leaded gasoline. We recommend that fuel stabilizer be added to the fuel

each time that gasoline is added to the fuel tank.

NOTE: Winter grade gasoline has higher volatility to improve

starting. Be certain container 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.

CAUTION: DO NOT use gasoline containing any

amount of alcohol as it can cause serious damage to

the engine or significantly reduce the performance.

START THE ENGINE

Be sure that engine oil is at FULL mark on the oil fill cap/dipstick. The snow

thrower engine is equipped with an A.C. electric starter and recoil starter. Before

starting the engine, be certain that you have read the following information.

If engine floods, set the choke to the OPEN/RUN position and crank until the en-

gine starts.

WARNING: The electric starter is equipped with a

three−wire power cord and plug designed to operate on AC

house hold current. The power cord must be properly

grounded at all times to avoid the possibility of electric shock

which can cause injury to the operator. Follow all instructions

carefully as set forth:

Make sure your house has a three−wire grounded system.

If you are not sure, ask a licensed electrician. If your house does

not have a three−wire grounded system, do not use this electric

starter under any condition.

If your house has a three−wire grounded system but a three-hole

receptacle is not available to connect the electric starter, have a

three−hole receptacle installed by a licensed electrician.

WARNING: To connect power cord, always connect the

power cord first to the switch box located on the

engine and then plug the other end into a three−hole

grounded receptacle.

WARNING: To disconnect the power cord, always

unplug the end connected to the three−hole grounded

receptacle first.

WARNING: Gasoline is flammable. Always use

caution when handling or storing gasoline. Turn

engine off and let engine cool at least two minutes before

removing the gas cap. Do not add gasoline to the fuel tank

while snow thrower is running, hot, or when snow thrower

is in an enclosed area. Keep away from open flame,

electrical sparks and DO NOT SMOKE while filling the fuel

tank. Never fill the fuel tank completely; but fill the fuel

tank to within 1-1/2 inches (3.8 mm) from the top to

provide space for the expansion of the fuel. Always fill fuel

tank outdoors and use a funnel or spout to prevent spilling.

Make sure to wipe up any spilled fuel before starting the

engine.

Store gasoline in a clean, approved container, and keep

the cap in place on the container. Keep gasoline in a cool

well ventilated place; never in the house. Never buy more

than a 30 day supply of gasoline to assure volatility.

Gasoline is intended to be used as a fuel for internal

combustion engines; therefore, do not use gasoline for any

other purpose. Since many children like the smell of

gasoline, keep it out of their reach because the fumes are

dangerous to inhale, as well as being explosive.

A

, Figure 10). Pull

the starter cord handle slowly until resistance is felt, then pull rapidly.

WARNING: Rapid retraction of the starter cord (kickback)

will pull your hand and arm toward the engine faster

than you can let go. Broken bones, fractures, bruises,

or sprains could result. When starting engine, pull the

starter cord slowly until resistance is felt and then pull

rapidly to avoid kickback.

NOTE: If the engine does not start after three attempts, see the

Engine Manual Troubleshooting section.

8. Electric Start: First connect the extension cord to the power cord

receptacle and then into a wall receptacle. If additional extension cord is

required, make sure it is three-wire.

WARNING: If the extension cord is damaged, it must

be replaced by the manufacturer (or its service agent)

or a similarly qualified person to avoid a hazard.

Starting with Electric Start Figure 11

IMPORTANT: To extend the life of the starter, use short

starting cycles (five seconds maximum). Wait one minute

between starting cycles.

CLEAR A CLOGGED DISCHARGE CHUTE

DANGER: Hand contact with the rotating impeller inside

the discharge chute is the most common cause of injury

associated with snow throwers. Never clear or unclog

discharge chute with your hands, or while engine is

running. Fingers can quickly become caught and

traumatic amputation or severe laceration can result.

OPERATING TIPS

1. Most efficient snowthrowing is accomplished when snow is removed

immediately after it falls.

2. For complete snow removal, slightly overlap each swath previously taken.

3. Snow should be discharged downwind whenever possible.

4. For normal usage, set the skids 1/8 inch (3 mm) below the scraper

bar. For extremely hard-packed snow surfaces, the skids may be ad-

justed upward to ensure cleaning efficiency.

5. On gravel or crushed rock surfaces, the skids should be set at 1-1/4

inch (32 mm) below the scraper bar (see “Adjust Skid Height” in the

MAINTENANCE section of this manual). Rocks and gravel must not

be picked up and thrown by the machine.

6. After the snowthrowing job has been completed, allow the engine to

idle for a few minutes, to melt snow and ice accumulated on the

engine.

7. Clean the snow thrower thoroughly after each use.

8. Remove ice and snow accumulation and all debris from the entire

snow thrower, and flush with water (if possible) to remove all salt or

other chemicals. Wipe snow thrower dry.

9. Before starting snow thrower, always inspect augers and impeller for

ice accumulation and/or debris, which could result in snow thrower

damage.

10. Check oil level before every start. Make sure the oil is at the FULL

mark on the oil fill cap/dipstick.

Clean-Out Tool Figure 13

LUBRICATE AUGER GEAR BOX

The auger gear box is lubricated at the factory and should not require

additional lubrication. If for some reason the lubricant should leak out,

or if the auger gear box has been serviced, add Lubriplate GR132 Grease or

equivalent. Maximum 3- 1/4 ounces, (92 grams) should be used.

Remove filler plug (A

A

, Figure 14), once a year. If grease is visible, do not

add. If grease is not visible, use a piece of fine wire, like a dipstick to check

if there is grease in the gear box. Mobilux EP1 and Shell Alvania EP1 are

suitable equivalents.
