OPERATION INFORMATION

ENGINE BREAK-IN

Engine break-in as a result of proper care during the first hours of operation of a new or rebuilt engine results in the ideal fitting of all internal moving metal parts, which is essential for top engine performance. For controlled engine break-in.

1. Operate the equipment as it is intended to be operated.

However, for the first 3 hours, if possible, operate the equipment at about half the available engine power, occasionally operating at full engine power for brief periods. Also, if possible, avoid prolonged low-speed, low-power operation during engine break-in.

2. Proper engine oil is especially critical during break-in because of the higher engine temperatures that can be expected. See RECOMMENDED ENGINE OIL.

Change the oil if it is not appropriate for the ambient temperatures during the break-in periods. See Table 1,

Figure 1 Page 6.

3. Check the oil level twice a day or after every 4 hours of operation during the first 24 hours of operation.

4. Change the oil and oil filter after the first 5 hours of operation.

After engine has reached operating temperature while pad is still off the floor. Before lowering burnishing head, adjust throttle to operating speed. After slowly lowering machine to floor, place hands lightly on the handle and allow the

machine to create the floor pressure. Bearing down and

pushing hard will lead to premature belt problems and operator fatigue. For smoother turns and greater maneuverability, buff aisles from the right side first.

CAUTION: DO NOT RUN MACHINE FOR MORE THAN 15

SECONDS IN ONE SPOT OR BURNING WILL OCCUR.

IDLING AND STOPPING THE MACHINE

If for any reason the machine needs to be idled for short periods, simply tilt machine back on its rear caster and release throttle bail into Idle Position. Machine will now idle safely. (CAUTION: DO NOT IDLE BUFFER ON REAR

CASTER FOR MORE THAN TWO MINUTES. This will raise the emissions level.)

OPERATION IN DUSTY CONDITIONS

1. Keep the engine cooling fins and flywheel air inlet screen and precleaner (filter) clean.

2. Perform air cleaner maintenance more often than normal - as required.

3. Change the engine oil more often than normal. See

Table 2, Page 10.

OPERATION IN HOT WEATHER

Pay particular attention to the following items when operating the engine in temperatures above 100°F (38°C):

1. Keep the engine cooling fins and flywheel air inlet screen and precleaner (filter) clean: See to it that nothing obstructs air flow to and from the engine.

2. Check the oil level more frequently.

3. Change the oil more often than normal. See Table 2,

Page 10.

4. Make sure the engine oil viscosity is appropriate for the ambient temperature and change the oil if necessary. See Table 1, Figure 1 page 6.

OPERATION IN COLD WEATHER

Pay particular attention to the following items when operating the engine in temperatures below freezing.

To stop machine tilt back on rear caster, turn valve on

propane tank off, and allow fuel in the lines to be used up.

FOR EMERGENCY SHUT OFF ONLY: turn off ignition

switch. Electric start models: use emergency stop switch on right side of control panel.

STORAGE

HOURLY CHECK

Due to the large amount of dust that can be encountered in floor care applications, the recoil dust filter should be checked after each hour of operation. Remove and clean the filter.

DAILY CHECKS

The operator should make a complete visual and audible inspection of the engine daily. Check the following before starting the engine for the first time each day.

1. Check all fuel lines and fitting for possible leakage.

2. Check crankcase oil level with the engine off. If engine has been run, allow a minimum of 10 minutes for the oil to drain down before checking. Check oil level with machine in operating position. Do not operate engine with the oil level below the ADD mark or above the FULL mark.

3. Inspect exhaust system for possible leakage and cracks. Locate leaks in muffler and piping while the engine is operating. Repair leaks immediately.

4. Inspect air cleaner system for leaks. Make certain all clamps and fittings are tight and free of potential leaks.

5. Check the engine cooling system to make sure the cooling fins and ducting area are clean. Remove dust, dirt or oil from the cooling surfaces.

DAILY (8 HOUR) MAINTENANCE

The operator should check the following before the first start of the day and after every eight hours of operation:

1. Inspect fuel lines and fittings for leaks. Repair leaks immediately.

2. Look and listen for exhaust system leaks while the engine is running. Look for cracks and severe rusting in the muffler and tailpipe. Have all leaks repaired before continuing to operate the equipment.

!

CAUTION

Hot exhaust parts can cause severe burns. Allow the engine time to cool before servicing the exhaust system.

3. Check the engine for dirt and debris and clean the flywheel air inlet screen and cylinder cooling fins as necessary. On floorcare equipment engines, remove the cooling air precleaner element every 4 to 8 hours of operation and wash it in warm water and mild detergent.

REGULATOR OPERATION

LP-gas vapor enters at point (A), then passes into primary area

(B) at point (28), where pressure is reduced from up to 250 p.s.i.

at the tank to 4 p.s.i. in area (B). Fuel pressure against diaphragm

(4) overcomes spring (6) and as movement increases, spring (9) will close lever (10). The primary diaphragm breather (not shown in drawing), is vented to secondary chamber so that rupture of this diaphragm would direct fuel into the carburetor.

Fuel now moves through passage (E), past secondary valve (29) into secondary area (C). As negative pressure (vacuum) is created at carburetor venturi and is transmitted through dry-gas hose to chamber (C) atmospheric pressure, exerted through vent hole

(G), forces down secondary diaphragm (18), secondary lever

(24) and spring (22). Fuel will flow in proportion to air velocity through carburetor venturi, insuring an ideal mixture at all engine speeds.

Whenever engine is operating, vacuum diaphragm (16) is down against floor (H) and spring (17) is collapsed. The idle and starting adjustment is made with tapered screw (27) which regulates the whisker wire system (not shown), opening up secondary orifice slightly (but only when vacuum diaphragm is drawn down). Very little vacuum is needed to start this vacuum diaphragm travel; 0.2”

Mercury to start and 0.5” Mercury for full travel. The instant engine stops rotating, loss of vacuum in section (D) releases diaphragm

(16), causing bumper (K) to push against secondary lever (24), overcoming action of whisker wire and insuring 100% lockoff.

This patented Beam design will lock off primary pressures up to five times in excess of normal, permits starting without priming or choking.
