Storage

When the engine is not in use, use the following

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 filter while the engine is still

warm from operation. See "Change Oil and Oil

Filter" on page 10.

3. Turn valve on LPG tank off and run engine until

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 storage. On dual-fuel units, the gasoline fuel

system must be completely emptied, or the

gasoline must be treated with a stabilizer to

prevent deterioration. If you choose to use a

stabilizer, follow the manufacturer's

recommendations, and add the correct amount for

the capacity of the fuel system. Fill the fuel tank

with clean, fresh gasoline. Run the engine for 2-3

minutes to get stabilized fuel into the carburetor.

Close fuel shut-off valve when unit is being stored

or transported.

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.

lower and affected by, but not limited to, accessories (air cleaner, exhaust, charging, cooling, fuel pump, etc.), application,

engine speed and ambient operating conditions (temperature, humidity, and altitude). Kohler reserves the right to change

product specifications, designs and equipment without notice and without incurring obligation. A horsepower reduction of

approximately 10 percent may be expected with the operation and use of LPG as fuel.
