WARRANTY.

H. Removing Snow from Engine

After each use, remove snow from the following areas:

Oil Fill Cap/Dipstick

Fuel Fill Cap

Recoil Starter/Flywheel Screen

Linkage

Guards

Spark Plug Connection (If visible).

Electric Starter Switch Box, if present (see equipment manufacturer’s instructions).

See "A. Engines with Electric Starters" instructions on page 10. Afterward, continue reading instructions below.

NOTE

See equipment manufacturer’s instructions for proper location of fuel fill cap and control lever.

Removing snow will ease operation of the recoil starter rope and reduce the risk of water contamination when opening fuel fill cap.

NOTE

For more information about recoil starters see "B. Engines with Recoil Starters" instructions on page 13.

VIII. Transporting Your Engine

NEVER transport this engine inside another vehicle or in any enclosed

space if there is any gasoline in the tank. Fuel vapor or spilled fuel may ignite.

If there is fuel in the fuel tank, close the fuel valve, if equipped, and

transport the engine upright in an open vehicle, such as an open trailer or open bed of a pickup truck.

If you DO NOT have an open vehicle and have to transport the engine upright in a closed vehicle, follow these steps for emptying the fuel tank before transporting:

1.Empty fuel tank by using a commercially available suction device designed for use with gasoline.

! WARNING

DO NOT pour fuel from engine or

siphon fuel by mouth.

 

2.Drain fuel into an approved red GASOLINE container, being careful to avoid spilling.

3.Run the engine until remaining fuel is consumed.

 

NEVER leave the engine
