storage procedure. Federal, state, or local laws
governing LPG fuel tank storage may also apply.
Follow the applicable storage laws.
1. Clean the exterior surfaces of the engine.
2. Change the oil and fi lter while the engine is still
warm from operation. See Change Oil and Oil
Filter on page 9.

the fuel system is empty. Turn ignition key switch
off . Separate LPG tank from the unit and store
separately in an area designated for safe LPG tank

4. Remove the spark plugs. Add one tablespoon of
engine oil into each spark plug hole. Install the
plugs, but do not connect the plug leads. Crank
the engine two or three revolutions.

fuel tank in a designated safe LPG storage area at
all times when not in use.
