OPERATION

CONNECTING THE PROPANE TANK

1. Make sure the engine is off and the propane tank is closed.

2. Unscrew the brass connector plug from the propane connector on the engine.

3. Connect the high pressure propane hose to the propane connector by turning the connector on the hose clockwise.

4. Connect the propane hose to the propane tank. The threads that connect to the propane tank are left
hand turn.

5. Open the valve on the tank slowly. Opening the valve too quickly could cause the sudden surge of
propane to activate a safety flow limiting device within the tank.

NOTE: Use only a high pressure propane hose. Do not use a hose with a regulator attached.

NOTE: When a new hose from a propane tank is being used, it may take a few seconds for the propane to
flow to reach the engine. The engine may start and then die, or not start immediately. A few extra
pulls of the starter are usually sufficient for the flow to reach the engine.
