FILL GAS:

The engine is certified to comply with California and US EPA emission regula- tions for ULGE (Utility or Lawn and Gar- den Equipment) engines. ULGE

engines are certified to operate on reg- ular unleaded gasoline.

_lb ARNING: Alcohol blended

fuels (called gasohol or

those using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel sys- tem of an engine while in storage.

NOTE: To avoid engine problems, the

fuel system must be emptied before storage for 30 days or longer. Start the

engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See the Storage sec-

tion in this manual for additional infor- mation.

Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

Fill the fuel tank only with a fresh, clean, unleaded regular, unleaded pre- mium, or reformulated automotive gas-

oline. DO NOT use leaded gasoline.

Make sure that the container you pour the gasoline from is clean and free from rust or other foreign particles. Never use gasoline that may be stale from long periods of storage in the container.

Fuel Tank

Figure 19

_lb ARNING: Gasoline is flam-

mable. Always use caution when handling or storing

gasoline.

• Do not fill fuel tank while snow

thrower is running, when it is hot, or when snow thrower is in an en-

closed area.

• Keep away from open flame or an electrical spark and do not smoke

while filling the fuel tank.

• Never fill the tank completely. Fill the tank to within 1/4"-1/2" from

the top to provide space for ex-

pansion of fuel.

• Always fill fuel tank outdoors and

use a funnel or spout to prevent

spilling.

• Make sure to wipe up any spilled fuel before stating the engine.

• Store gasoline in a clean, ap-

proved container and keep the

cap in place on the container.

TO START ENGINE

Be sure that the engine has sufficient oil. The snow thrower engine is equipped with a recoil starter. Before starting the engine, be certain that you have read the following information.

4_lk WARNING: The starter is

equipped with a three-wire power cord and plug and is

designed to operate on 120 volt AC

household current. It must be prop- erly grounded at all times to avoid the possibility of electrical shock which may be injurious to operator.

• Follow all instructions carefully

as set forth in the "To Start En- gine" section.

• Determine that your house wiring

is a three-wire grounded system. Ask a licensed electrician if you are not sure. If your house wire

system is not a three-wire system, do not use this electric starter un-

der any conditions.

• If your system is grounded and a

three-hole receptacle is not avail- able at the point your starter will

normally be used, one should be

installed by a licensed electrician.
