FILL THE FUEL TANK

This engine is certified to operate on gasoline. Exhaust Emission Control

System: EM (Engine Modifications).

Fill the fuel tank with fresh, clean, unleaded regular, unleaded premium, or re-

formulated automotive gasoline with a minimum of 85 octane along with a

fuel stabilizer (follow instructions on fuel stabilizer package). D

DO NOT

use

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.

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 snowthrower is running, hot, or when snowthrower 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.

START THE ENGINE

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

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.

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 snowthrowers. 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 snowthrower thoroughly after each use.

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

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

other chemicals. Wipe snowthrower dry.

9. Before starting snowthrower, always inspect augers and impeller for

ice accumulation and/or debris, which could result in snowthrower

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 19

A

• SHUT OFF THE ENGINE!

• Wait 10 seconds to be sure that the impeller blades have stopped

rotating.

• Always use a clean-out tool, not your hands.

A clean-out tool (A

A

, Figure 19) is attached to either the handle or the top of the

auger housing. Use the clean-out tool to remove snow from the auger housing.
