DANGER: It is the owner/operator's responsibility to ensure that the air-exchange system installed in any location where a propane floor care machine is being operated is of sufficient capacity and quality to support the use of such a machine. OSHA and other County,

State, or Federal Agencies publish guidelines on this subject that are usually most readily found in the possession of the respective owners and/or parent companies of any location or chain of locations. Failure on the part of the owner/operator to ensure that a propane floor care machine can be operated safely in a given location may lead to injury, sickness or even loss of life.

This Owner's Manual/Safety Procedures Guide has been prepared for the promotion of educational purposes only and

Clarke does not claim or assume any responsibility for the operator's actions or safety. To be completely aware of what local authorities may require, contact the Fire Marshal of your community.

Engine Emissions and CO Safety

The purpose of this document is to provide information on:

· The potential effects of CO exposure;

· The methods to reduce the risk of CO poisoning;

· The methods used to determine the amount of potential exposure to CO produced by equipment.

DANGER: All LPG (Liquid Propane Gas) powered engines, including this engine, produce

Carbon Monoxide (CO). It is a LETHAL POISON that is a colorless, odorless, tasteless, and non-irritating gas. It is produced by incomplete combustion of carbonaceous material such as propane (LPG).

Failure to provide for proper venting of CO produced during the operation of combustion powered engines may result in SERIOUS INJURY OR DEATH to the operator and those in the contaminated area.

The effects of CO can be experienced at different exposure levels, depending on the health of the individual. Conditions that affect the tolerance of the individual are smoking, age, temperature, humidity, and other conditions.

WARNING: Read and understand The Operators Manual completely before using this machine

This document explains how CO produced can be managed to reduce the risk of carbon monoxide poisoning.

All distributors, owners, and operators should be aware of the potential effects of CO and the methods used to prevent over exposure.

ALTO U.S. is dedicated to our customers, their safety, and providing information, services, and products that meet those needs.

Information provided in this document is current as of the date written November 1997.

Document Overview

The information provided in the following overview has been condensed to provide the reader with a summary of the material presented.

Potential Effects of CO Exposure

· Work place/industry guidelines for CO exposure limits vary substantially from region to region (OSHA) Permissible Exposure Limit (PEL) for CO is 50 ppm, as an

8-hour time weighted average.

· Definition of CO effects - The toxic effects of carbon monoxide in the blood are the result of tissue hypoxia (lack of oxygen). The severity depends on the state of activity of the individual and his tissue oxygen needs.

Methods to Reduce The Risks of CO Poisoning

· Air Exchange and CO Diffusion - CO does not mix with air on its own. Air currents can “stir” the CO and dilute the concentration values by mixing it with the available air. When using equipment over a large area in a short time “stirring” occurs as you walk.

· Application Considerations (Burnishing versus Stripping) - When activity is concentrated to a smaller area as in a stripping application, air “stirring” must be forced by the use of fans to reduce the risk of high concentrations of CO.

· Air Quality Monitoring – Deployment of a monitor/detector is essential for the safe operation of any equipment that has the potential to produce CO.

· Room Size and Time Estimations - The concentration and volume of CO production, the size of the area and the amount of air exchange are factors involved with determining safe time limits for operation in a specific room size.

· Maintenance of Equipment - LPG engines are dependent on engine tune up, and air filter replacement. CO concentration (production) skyrockets when the air to fuel ratio becomes fuel rich. Follow the recommended Maintenance Schedule for the engine.

· Safety Equipment Available. - Envirogard automated fuel to air ratio monitoring and regulation providing an optimum combustion, three-way type catalytic converter to scrub CO, Hydro Carbons (HC), and Nitrous Oxide (NOx) from the engine exhaust providing the lowest possible emissions, high cubic feet per minute (CFM) fans

(forced air mixing), and digital combustion analyzers for tail pipe emissions monitoring.

Potential Effects of CO Exposure

· Work place/industry guidelines for CO exposure limits

· Definition of CO effects

Work place/industry guidelines for CO exposure limits

Limits for permissible exposure to CO vary substantially from region to region. City, State, and

Industry requirements should be consulted prior to use of any equipment.

The current Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit

(PEL) for CO is 50 ppm, as an 8-hour time weighted average (TWA). This is computed by making measurements at intervals over 8 hours, then adding the sums of the concentrations and the intervals, and dividing by 8 hours. For example:

Time Interval

Time intervals =

50 ppm = 400

The current National Institute for Occupational Health and Safety (NIOSH), immediately dangerous to life and health concentration (IDLH) recommended level for CO is 1,200 ppm. NIOSH defines the IDLH exposure level as the concentration that could result in irreversible health effects or death, or prevent escape from the contaminated environment within 30 minutes.

Definition of CO effects

The toxic effects of carbon monoxide in the blood are the result of tissue hypoxia (lack of oxygen). carbon monoxide combines with hemoglobin to form carboxyhemoglobin. Since CO and oxygen react with the same group in the hemoglobin molecule, carboxyhemoglobin is incapable of carrying Oxygen. The affinity of hemoglobin for CO is 200 to 240 times greater than for oxygen. The extent of saturation of hemoglobin with CO depends on the concentration of the gas, the quantity of inspired air and on the time of exposure. The severity depends on the state of activity of the individual and his tissue oxygen needs.

According to Harrison’s Principles of Internal Medicine 7th edition, no symptoms will develop at a concentration of 0.01% CO (100ppm) in inspired air, since this will not raise blood saturation above 10 %.

Exposure to 0.05% (500ppm) for 1 hour during light activity will produce a blood concentration of 20% carboxyhemoglobin and result in a mild or throbbing headache. Greater activity or longer exposure causes a blood saturation of 30 to 50 %. At this point head ache, irritability, confusion, dizziness, visual disturbance, nausea, vomiting, and fainting can be experienced. Exposure for one hour to concentrations of

0.1% (1000ppm) in inspired air the blood will contain 50 to 80% carboxyhemoglobin which results in coma, convulsions, respiratory failure and death. On inhalation of high concentrations of CO, saturation of the blood proceeds so rapidly that unconsciousness may occur suddenly without warning.

· Room Size and Time Estimations

· Maintenance of Equipment

· Safety Equipment Available

Air Exchange and CO Diffusion

The most reliable method to prevent CO Poisoning is to ensure all the CO produced is vented outside.

With wood stoves or gas heaters this is performed with ductwork that carries the exhaust and CO outside.

Non-stationary combustion type equipment must be used in such a way that CO is not allowed to rise to a harmful or dangerous level.

CO does not readily dissipate or mix with air on its own. Air currents can “stir” the CO and dilute the concentration or ppm values by mixing it with the available air. When using equipment over a large area in a short time “stirring” occurs as you walk, or to say it another way, your Effective Operating Zone is large.

When activity is concentrated to a smaller area as in a stripping application, the Effective Operating Zone is small, and “stirring” must be forced by the use of fans to increase the Effective Operating Zone and reduce high concentrations of CO.

Air exchange rates (air exchange is defined as the exhausting of internal air to the external atmosphere), the size of the Effective Operating Zone, amount of CO produced, level of human activity, and the duration of exposure are all factors in the determination of the production of carboxyhemoglobin and the amount of CO blood saturation.

Application considerations (Burnishing versus Stripping)

When using equipment over a large area in a short time, as in most burnishing applications, your

Effective Operating Zone is large. When activity is concentrated to a smaller area as in stripping applications, the Effective Operating Zone is small and stirring or CO mixing MUST be forced by the use of fans to increase the Effective Operating Zone and reduce high concentrations of CO.

Caution: air mixing in itself may not be sufficient to reduce CO to a safe level.

The Effective Operating Zone can be defined as the area covered in a given time.

Stripping is quite a different type of operation than burnishing, and carries with it substantially more hazards, as stripping is a low movement operation compared to burnishing (less floor space for the same time). As shown in Model 1, the CO concentrations rise much quicker as the “Effective Operating Zone” is a very small area compared to the total building size.

IV

Notice the CO concentration and the Effective Operating Zone with air exchange. The CO cloud is still concentrated in a small area. Note the “Dividing Zone” shown above, this is the line where airflow changes direction. In Model 2, air changes are cut in ½ as little or no CO crosses the Dividing Zone to be exhausted.

Notice the CO concentration and the Effective Operating Zone (Expanded to the Dividing zone) with air exchange and forced air mixing. The CO cloud is still concentrated on one side of the Dividing zone.

Note the “Dividing Zone” shown above, this is the line where airflow changes direction. In Model 3, air changes are cut in ½ as little or no CO crosses the Dividing Zone to be exhausted.

Notice the CO concentration and the Effective Operating Zone (Expanded through the Dividing zone to the second vent) with air exchange and forced air mixing through the dividing Zone. The CO cloud is diluted with the available air in the building. Note the “Dividing Zone” shown above, this is the line where airflow changes direction. In Model 4, air changes are full as forced air mixing has moved and mixed the

CO between all air zones.

Air Quality Monitoring

Warning Deployment of a monitor/detector is essential for the safe operation of any equipment that has the potential to produce CO. CO sensors/detectors became available on the mass market around

1978. At present several brands sell in the fifty-dollar range. The main differences between the technologies involved are battery or electric and Semiconductor or Biomimetic types. Detectors for carbon monoxide (CO) are manufactured and marketed for use in either the home or occupational industrial settings. The detectors for home use are devices that will sound an alarm before CO concentrations in the home become hazardous. There is an Underwriters Laboratories, Inc., performance standard (UL 2034) for residential CO detectors. Detectors currently available on the market are battery-powered, plug-in, or hardwired. Some models incorporate a visual display of the parts per million (ppm) concentration of CO present in the home. For more information on CO detectors for home use, call the Consumer Product Safety

Commission Hotline at 1-800-638-2772.

CO detectors for use in residential settings are not designed for use in typical workplace settings.

Monitoring requirements in an occupational setting are different from monitoring requirements in the home. In the workplace, it is frequently necessary to monitor a worker's exposure to carbon monoxide over an entire work shift and determine the time-weighted average (TWA) concentration of the exposure. It may also be necessary to have carbon monoxide monitors with alarm capabilities in the workplace. The directreading instruments are frequently equipped with audio and/or visual alarms and may be used for area and/or personal exposure monitoring. Some have microprocessors and memory for storing CO concentration readings taken during the day. It is significant to note that some of the devices mentioned for workplace CO monitoring are not capable of monitoring TWAs, and not all are equipped with alarms. The appropriate monitor must be chosen on an application-by-application basis. For more information on the availability of workplace CO monitors or their application, call the National Institute for Occupational

Safety and Health at 1-800-35-NIOSH (1-800-356-4674).

Room Size and Time Estimations for Parts Per Million (PPM) CO

The fundamental factors in area CO levels involve:

The concentration and volume of CO production;

The size of the area;

The amount of *air exchange if any;

The amount of time CO is produced.

Multiplying length, width, and height will determine the volume or cubic feet in a room. So an empty building 100ft by 100ft with a 10ft ceiling would be 100,000 cubic ft. in size. Any material that is in the room and takes space would reduce the cubic feet.

*Air exchange is defined as the exhausting of internal air to the external atmosphere.

The Graph above depicts the relationships of air exchange to time and CO ppm with cubic feet area and percent CO emissions remaining constant.

If the symptoms still persist, discontinue operation of the machine.

WARNING: Onan Machines. Insulation installed in the new muffler may become loosed in the initial few hours of operation. This material will lodge in spark arrester in the muffler exit port. Onan requires that the spark arrester be removed and cleared of all debris after the first five hours of operation and as part of regular maintenance. Failure to perform this maintenance can rfesult in severe engine over-heating.

Introduction

Clarke propane floor care equipment is manufactured in two basic concepts: the buffer/burnisher and the floor stripper. Both of these designs are truly PORTABLE equipment. Propane buffers are best defined as ultra high speed buffers with the staying power to produce superior high gloss floor surfaces. Upon contact with the floor, the buffer should always be kept moving. The speed at which you walk will determine the results that you will obtain. Slower speeds create more heat and therefore more shine. Clarke recommends a moderate pace for best results and safe operation. NEVER RUN

WITH THE BUFFER!! While a credible shine will still result, the danger of trying to stop the machine in an emergency situation is unacceptable. When buffing, avoid loose tile, electric outlets, door thresholds and any object which may come in contact with the pad other than the floor itself. REMEMBER, the pad is turning very rapidly.

Proper care and maintenance will protect your investment and keep your machine serving you for many years to come. It is essential that these issues are closely followed:

CAUTION: Overfilling the propane tank is the number one cause of problems with a propane machine. This can cause the engine to run poorly or not at all.

Page 4

In addition, overfilling allows liquid propane to enter the fuel control system, possibly ruining the lockoff/regulator assembly. This voids the warranty on affected parts of the machine. To avoid problems, read and understand fully, the section "Filling and Storing Propane Tanks."

OVERHEATING is a major cause of engine failure.

Keep the cooling air bonnet filter clean. Protect your machine; don't allow wax dust/lint to build up on the cooling fins of the engine cylinder(s). A good high pressure spray wash directed at the fins when the

engine is cold will prevent this from happening.

LOW OIL AND DIRTY OIL account for most of the other failures. Clarke recommends changing the oil

on a regular schedule, perhaps exceeding that which is found in the engine manufacturers' manual.

Checking the oil daily, before putting the machine to work, is a good habit to get into and could save you the downtime and expense of replacing the engine due to oil starvation. AFTER AN OIL CHANGE, MAKE

SURE YOU HAVE REPLACED THE OIL SUPPLY

BEFORE RESTARTING THE ENGINE.

Propane Safety Information

Facts About LP Gas - Propane

As a fuel, Propane gas is unmatched for both safety and dependability. It has been used as a domestic household fuel for over half a century, and for over thirty years as an internal combustion engine fuel. Propane is a highly flammable fuel that is contained under pressure as a liquid. Vaporized gas has a similar explosive force to gasoline and mixtures as low as 2% LP Gas to air may be ignited in a closed environment. Care should be exercised to avoid escaping vapor as it can freeze skin and cause frost bite. Vaporized fuel is heavier than air and will collect in the lowest confined space available.

Facts About Propane Tanks

Propane tanks are constructed according to ASME or

Federal DOT #4ET20 pressure safety codes. Including the tank, all valves and fittings are UL Listed. Propane gas is noncorrosive and will not rust the inside of a tank. Should the tank exterior become damaged or rusted, discontinue use. DO NOT tamper with tank gauges or safety relief valves. NEVER use a tank not intended for use with a propane buffer. DO NOT substitute tanks that are used with a barbecue grill, etc. A. L. Cook recommends having propane tanks tested once a year by an authorized

National LP Gas Association sanctioned propane dealer.

3.

Make the connection to the quick coupler (A purge manifold system is most effective). Fully open the cylinder service valve as well as the outage valve. Vent to a safe atmosphere. A vent stack is recommended.

4.

On Overfill Prevention Device cylinders, the purge time is increased as a result of the new valve design. Opening the outage valve will help improve the speed of the purge.

5.

Repeat #3 and #4 for a total of FIVE purges.

6.

Repressurize the container with odorized LP-gas vapor to 15 psig.

7.

The container is now ready to be filled with LP-gas.

8.

Once filled, check all fittings and tank openings for leaks using an approved leak detector solution.

9.

The container is now ready to be placed in service. Add

DOT and OSHA labels.

Symptoms of a non-purge cylinder:

• Relief valve opens due to over pressurized cylinder creating hazardous situation.

• Moisture in the cylinder.

• Buffer operates initially but shuts down when fuel mixture becomes too lean.

The fuel tank is supplied directly from the manufacturer and is void of fuel. This tank must be purged at the time of the first fill. Local fuel vendors should be familiar with this operation and will provide this service.

Recommended Purge Procedures

How to purge new LP-Gas Buffer cylinders equipped with the Overfill Prevention Device:

New containers may contain vapor, air, or other contaminants. It is essential that these be removed before filling the container and placing it into service. Air in the container will cause abnormally high pressure, with the result that the pressure relief valve may open. Air in the system is also likely to cause lean mixture, making

ignition difficult. If a cylinder is suspected of being depressurized or open to the atmosphere for a period of time, it must be re-purged as if it were a new container.

Refilling & Storing Propane Tanks

The NFPA Technical Committee prohibits the storage of such containers in buildings. There are few exceptions to this rule. In other words, propane tanks should NOT be stored in buildings used by the public or frequented by anyone passing through or who is working in the building.

Full or empty, never leave tanks in small enclosed areas.

The tank(s) must be in a secure, tamper-proof storage enclosure that provides safety from accident or vandalism.

PROPANE TANKS SHOULD ALWAYS BE

TRANSPORTED, INSTALLED AND USED IN AN

UPRIGHT POSITION.

To purge a container, the following steps should be taken.

Purging of containers should be performed in an approved area (see NFPA #5 8) using NPGA #13 3.89(a) procedure.

OVERFILLING PROPANE TANKS IS HAZARDOUS.

The tank should NEVER be completely filled with liquid propane. 80% of the total tank volume is to be considered at ALL times as full. EXPANSION MUST BE ALLOWED

FOR. Propane Buffer tanks are equipped with a fixed liquid level gauge which contacts the liquid level at 80% of container capacity, allowing 20% for expansion. The top part of this device must be unscrewed counterclockwise so that vapor can escape through the small hole it its side, as the tank is refilled. When the escaping vapor starts to give way to liquid, the device must be quickly closed and the propane nozzle turned off.

1.

Determine if the container pressure is zero. Should the cylinder contain only pressurized air, the air may be vented directly to the atmosphere through the service valve using an adapter and the outage valve.

2.

Pressurize the container to approximately 15 psig with LPgas vapor. Never purge with liquid LP-gas! To do so will cause the moisture vapor to chill and remain in the cylinder. LPgas liquid also expands 270 times to vapor making the purge process ineffective. Use LPgas vapor only!

**IMPORTANT** The engine and the fuel system on your floor care machine are designed to run on fuel vapor, not fuel liquid. Overfilling the propane tank will result in damaging the lockoff and/or regulator. This will

VOID the WARRANTY on these components.

How to Operate the Machine Maintenance And Adjustments

Preparing The Machine For Use

BEFORE using any type of powered equipment, proper safety dictates you should visually inspect it.

1.

Adjust the HANDLE to a comfortable height and tighten the bolts to 30-50- ft/lbs.

2.

BONNET FILTER - Make sure the bonnet air filter atop the engine is clean. It should be changed hourly and thoroughly cleaned before reuse.

3.

Check the engine OIL LEVEL. Make sure the machine is in a level position.

** HONDA - DO NOT screw the dipstick in to get reading.

**KAWASAKI - DO NOT screw the dipstick in to get reading.

4.

Fill the tank following the instructions as given under the previous heading: "Refilling And Storing Propane Tanks." In addition, if your buffer came with an "80% Safety Fill Tank" then it should ONLY be filled through the threaded valve with the larger diameter that is covered by a yellow cap to ensure a "Full" level that is safe.

5.

PAD AND PAD HOLDER - Inspect the condition of the pad and pad holder. Is there a pad? Is it properly attached? What is its condition? Ensure the pad is clean and has at least a thickness of 1/3 inch. ALWAYS turn off the engine to clean or replace pad.

6.

TANK and FUEL LINES - The tank has already been covered but do the fuel lines show any sign of wear and tear, such as cracks or any corrosion? Screw the brass fuel line fitting onto the tank service valve hand tight only. This connection MUST be secure because the service valve has a safety valve inside it which will only open if the brass fuel line fitting is COM-

PLETELY seated into the service valve.

Starting the Engine

1.

Plug in 110 volt starter cord on models so equipped.

2.

We recommend setting the throttle on models with 110 volt starter to the following positions:

** HONDA - Set throttle/choke to the "choke" position.

**KAWASAKI - The KAWASAKI single cylinder and Kawasaki twin cylinder engines are designed to be started in the IDLE throttle position. This creates a vacuum necessary to open the lock-off valve inside the regulator. Actuation of the throttle lever will keep the lock-off valve from opening and the engine from getting fuel so the engine will not start. Proper maintenance will insure easy starting.

3.

Open (counterclockwise) the service valve on the propane tank about one and a half turns.

4.

Ensure the buffer is tilted back so that the pad is off the floor on all machines without a clutch.

5.

Engage starter for a MAXIMUM of 5 to 6 seconds or until the engine fires. Serious starter damage will result if this is exceeded and the warranty may not apply.

6.

Open the "choke" until the engine runs smoothly. (HONDA

ONLY)

7.

Operate the engine at half throttle for approximately two minutes for proper warm-up. Then advance to full throttle for best results.

NOTE: If the engine refuses to start, see the Trouble Shooting Guide.

Stopping The Engine

1.

Close (clockwise) the service valve on the propane tank.

2.

ALWAYS allow the engine to run until it stops from lack of fuel.

** ONLY IN AN EMERGENCY should the "stop" position on a

HONDA throttle or the "kill switch" on a KAWASAKI and ONAN models be used.

3.

Disconnect the fuel line from the tank.

4.

REMEMBER, when you are finished with the machine, store the propane tank outside the building, in a safe place away from heat or direct sunlight.

Emission Control Information

To protect the environment in which we will live, the manufacturer has incorporated crankcase emission (1) and exhaust emission

(2) control systems (EM) in compliance with applicable regulations of the United States Environmental Protection Agency and

California Air Resources Board.

1.

Crankcase Emission Control System. A sealed-type crankcase emission control system is used to eliminate blow-by gases. The blow-by gases are led to the breather chamber through the crankcase. Then, it is led to the air cleaner. Oil is separated from the gases while passing through the inside of the breather chamber from the crankcase, and then returned back to the bottom of crankcase.

2.

Exhaust Emission Control System. The exhaust emission control system applied to this engine consists of a carburetor and an ignition system having optimum ignition timing characteristics. The carburetor has been calibrated to provide lean air/fuel mixture characteristics and optimum fuel economy with a suitable air cleaner and exhaust system.

Tampering w/Emission Control System Prohibited

Federal law and California State law prohibits the following acts or the causing thereof: (1) the removal or rendering inoperative by any person other than for purposes of maintenance, repair, or replacement, of any device or element of design incorporated into any new engine for the purpose of emission control prior to its sale or delivery to the ultimate purchaser or while it is in use, or (2) the use of the engine after such device or element of design has been removed or rendered inoperative by any person.

Among those acts presumed to constitute tampering are the acts listed below:

Do not tamper with the original emission related part.

>Carburetor and internal parts

>Spark plugs

>Magneto or electronic ignition system

>Fuel filter element

>Air cleaner elements

>Crankcase

>Cylinder heads

>Breather chamber and internal parts

>Intake pipe and tube

General Maintenance and Adjustments

1.

Fuel control system. To ensure personal safety, adjustments should ONLY be made by a qualified LPG system technician or an authorized service center, using an exhaust gas analyzer. Do not operate the machine if carbon monoxide levels exceed OSHA standards.

2.

Pad replacement. Tilt the machine back on its rear caster to reach the pad centering device. Turn the outer ring counterclockwise to remove it. Remove the old pad. Install the new pad by carefully centering it against the "harpoon hook" plastic gripper. Replace the center locking ring. Check rotation of the pad driver.

Eccentricity of the pad should not exceed 1/4 of an inch.

Clarke ® Propane Burnishers Operator's Manual

Maintenance And Adjustments

3.

Belt replacement. Tilt the machine on its side

(observing the following precautions) and block securely.

**KAWASAKI and HONDA single cylinder - Do not

turn the carburetor side down. Oil will enter the intake manifold and may cause engine damage. Turn the machines with the exhaust side down.

**KAWASAKI twin cylinder - Do not tilt the machine on its nose as this is where the carburetor is located. It is okay to turn this model on either its left or right side.

(a) Remove pad.

(b) Use a suitable wrench to secure the top of the shaft and spin off the pad driver and remove it from the machine.

(c) Remove old belt carefully and completely.

(d) Install new belt and adjust the pressure of the

Lovejoy tensioner.

(e) Reinstall pad driver.

Recommended 20 Hour Maintenance Items -

>Change engine oil.

>Check pad driver for loose parts.

>Check belt for wear or slippage.

>Check engine pulley for tightness.

>Check wheel bolts.

>Check engine mount bolts.

>Check handle bolts.

>Check for leakage of engine oil at the various seals.

Recommended Oil Change Intervals

Do not exceed the 20 hour oil change interval. Oil changes more frequent than 20 hours will give even longer engine life. In any case, always use 30HD or

10W30 engine oil with all of the following ratings: SF, SG,

CC. The various engines have different oil sump capacities. Make sure the oil level is maintained at the "FULL" level.

Recommended 200 Hour Maintenance

Return machine to authorized service center for overall checkup.

Clarke ® Propane Burnishers Operator's Manual

Trouble Shooting

When troubles occur, be sure to check the simple causes which at first, may seem too obvious to be considered.

For example, a starting problem could be caused by fuel starvation due to an empty propane cylinder or an unopened service valve. If you don't check for this, starter burnout could result.

1.

KAWASAKI - "SURGING IDLE" - To smooth out the engines' idle characteristics, adjustment is provided by an idle screw on the lower left side of the carburetor as viewed from the operator's position. The screw is bright steel and 1/4" in diameter with a Phillips head on it. Rotating the screw clockwise will increase the idle speed and this should cure the "surging idle".

IF IT DOES NOT, call our customer service department for assistance.

2.

EXCESSIVE VIBRATION - Look for the following possibilities:

(1) Pad is off center. Remove and reinstall.

(2) Pad Driver is bent or cracked. (Possibly from striking a curb or bolt in the floor.) Replace immediately with a new part only.

(3) Bearings in Front End Assembly are worn. Place machine on its side where the muffler is mounted. Grip Pad Driver and move up, down and from side to side to check for slack in the bearings. If this is the case, then to effect a proper repair, the bearings should be replaced and possibly the shaft.

(4) Check to see if the bolts on shaft housing are tight. Look to see if the nuts, bolts and spacers on the Flex Coupler Assembly are all in place and tight.

3.

ENGINE STARTS AND IDLES, BUT WILL QUIT AS

THE THROTTLE IS ADVANCED - It is possible that the propane tank's service valve is faulty. To check for this, close the valve completely and then reopen very slowly while you listen for a "click" when the gas begins to travel through the valve. If you hear this very slight noise, then what is happening is the valve is only partially opening. This allows enough gas through to start and idle the engine, but not enough for full throttle operation. As the throttle is increased, allowing more air to enter the intake, the engine will quit from fuel starvation. Call your dealer or the factory for instructions on where to have the service valve replaced. Meanwhile, to get by, you can continue to open the service valve until you don't hear a "click" and then the engine will run normally. IF IT

DOES NOT, call our customer service department for further assistance.

4.

THE BUFFER SEEMS TO RUN WELL BUT DIES

DOWN WHEN THE PAD IS PLACED ON THE

FLOOR OR SOON THEREAFTER - Check for the same problem as in #3.

5.

EXCESSIVE NOISE FROM UNDER BUFFER - If this problem has developed after use of the machine from new, then the first place to check is the Lovejoy

Tensioner. As a new belt wears in, it naturally stretches a bit and the tensioner will begin to rattle.

Place the buffer on its side (with the muffler down) and reset by taking up the slack in the belt and tighten the Lovejoy Tensioner.

Page 7

Trouble Shooting

6.

STARTER WILL HARDLY TURN THE ENGINE

OVER or THE SOLENOID JUST CLICKS ON 12

VOLT OPTION MODELS - The battery is likely low in charge. This can be remedied by recharging the battery using a 12 volt battery charger at 4-12 amperes. The battery is located under the frame at the rear of the buffer. The positive post is the one with the RED cable attached to it. Follow the instructions that came with the battery charger.

REMINDER: this will continue to happen unless the buffer's engine is run for sufficient time between starts to recharge the battery.

7.

KAWASAKI V-TWIN - ENGINE BACKFIRES

LOUDLY AND REGULARLY SUDDENLY - Check the sparkplug boots. One of them is likely cracked, possibly due to contacting a corner of a shelf or a door frame. Remove the sparkplug lead from the sparkplug and replace the boot with a new one. The engine should now run normally. IF IT DOES NOT contact our customer service department for further assistance.

8. KAWASAKI SINGLE CYLINDER - HARD STARTING

- You've tried the normal methods and the engine still refuses to start and run. Remove the fuel hose from the cylinder and press in on the valve which is inside the quick coupler fitting on the end of the hose. This will release the built up pressure in the system and care should be taken not to be "burned" by the escaping gas. Then reattach the fuel line to the propane cylinder but DO NOT open the service valve.

Set the throttle at approximately 1/2 and press the starter button. Allow the engine to turn over about 2 or

3 times and then open service valve at least 1½ full turns. The engine should now be running. IF IT

DOES NOT, contact our customer service department for further assistance.
