PROPANE SAFETY INFORMATION
Facts About
Liquid Propane
Gas (LPG)
As a fuel, propane gas is unmatched for both safety and dependability. It has been used a 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.
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 the tank gauges or safety relief valves. NEVER use a tank not intended for use with a propane burnisher. DO NOT substitute tanks that are used with a barbecue grill, etc. WerkMaster recommends having propane tanks tested once a year by an authorized
National LP Gas Association propane dealer.

Purge Procedures
The fuel tank is supplied directly from the manufacturer and is void of fuel.
The tank must be purged at the time of the first fill. Local propane fuel vendors should be familiar with this operation and will provide this service.
WARNING
DO NOT attempt to repair the tank. Return the tank to your propane if necessary.

New containers may contain vapor, air, or other contaminants. It is essential that these be removed before filling the container and putting 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 a lean mixture, making ignition difficult. If a tank is suspected of being depressurized or open to the atmosphere for a period of time, it must be re-purged.
See an authorized propane dealer for proper purging of your new tank.
Symptoms of a non-purged propane tank:
• Relief valve opens due to over-pressurized propane tank creating
hazardous situation
• Moisture in the propane tank
• Burnisher operates initially but shuts down when the fuel mixture
becomes too lean.
