BEFORE STARTING THE ENGINE

Before you service or start the en- gine, familiarize yourself with the snow thrower. Be sure you under-

stand the function and location of all controls.

Check the tension of clutch cable before starting the engine. See To

Adjust The Control Cable para- graph in the Service & Adjust-

ments section of this manual.

Be sure that all fasteners are tight.

Make sure the height adjust skids are properly adjusted. See To Ad- just Skid Height paragraph in the Service & Adjustments section of

this manual.

Check tire pressure (14-17 pounds). Do not exceed maximum amount of pressure.

CHECK THE OIL:

NOTE: The engine was shipped from the factory filled with oil. Check the lev- el of the oil. Add oil as needed.

F-021073L 15

When the temperature falls below 32 de- grees, use the heated grips to keep your

hands warm. Move the heated grip switch to the ON position (see Figure 14). It will

take a couple of minutes for the grips to be- come warm. Because heated grips can be-

come very warm, we recommend that you wear gloves. If you notice that the grips are too warm, turn off heated grips.

To Add Oil

1. Make sure the unit is level. NOTE: Do not check the level of the

oil while the engine runs.

2. Remove the oil fill cap/dipstick. Check the oil.

3. If necessary, add oil until the oil reaches the FULL mark on the oil fill

cap/dipstick (see Figure 16). Do not add too much oil.

OII Fill Cap/Dipstick

NOTE: Oil levelmust be between Full and Add mark

Figure 16

4. Tighten the fill cap/dipstick securely each time you check the oil level.

NOTE: S.A.E. 5W30 motor oil may be

used to make starting easier in areas where temperature is consistently 20°F. or lower.

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.

_ 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

_ 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.

_ ARNING: 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.

• When connecting 120 volt AC "Power Cord", always connect the

cord to the Switch Box on the en- gine first, then plug the other end

into the three-hole grounded re- ceptacle. When disconnecting

"Power Cord", always unplug the end in the three-hole grounded re-

ceptacle first.

SNOW THROWING TIPS

1. For maximum snow thrower efficien- cy in removing snow, adjust ground

speed, NEVER the throttle. Go slower in deep, freezing or wet snow. If the wheels slips, reduce

forward speed. The engine is de- signed to deliver maximum perfor- mance at full throttle and should be

run at this power setting at all times.

2. Most efficient snow throwing is ac- complished when the snow is re- moved immediately after if falls.

BELT ADJUSTMENT

Traction Drive Belt

After approximately ten hours of opera- tion, a new belt will stretch and require

an adjustment of the belt tension. Also, if your snow thrower experiences a loss

of power under heavy load, check the condition of the traction drive belt. If it is

damaged or loose, replace it (see "How To Replace The Belts" in this section of the manual).

1. Disconnect spark plug wire.

2. Unlock both left and right wheel

locks. See "How To Use The Wheel Lockout" in the Operation section.

3. Remove screw from belt cover. Remove belt cover (see Figure 34).
