cord after the engine starts.
Fuel Handling
DANGER
WHEN ADDING FUEL
• Turn off engine and let cool at least 2 minutes before removing the fuel
cap and adding fuel.
• Fill fuel tank outdoors or in a well ventilated area.
• Do not overfill the fuel tank. To allow for the expansion of gasoline, do not fill
above the bottom of the fuel tank neck.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other
ignition sources.
• Check fuel lines, cap, and fittings frequently for cracks or leaks. Replace if
necessary.
• Use an approved fuel container.
• If fuel spills, wait until it evaporates before starting engine.
WHEN STARTING ENGINE
• Ensure that spark plug, muffler, fuel cap, and air cleaner (if equipped) are in
place and secured.
• Do not crank the engine with the spark plug removed.
• If fuel is spilled, do not attempt to start the engine, but move the snow
thrower away from the area of the spill, and avoid creating any source of
ignition, until the fuel vapors have dissipated.
• Do not over-prime the engine. Follow the engine starting instructions in this
manual.
• If the engine floods, set choke (if equipped) to OPEN/RUN position, move
throttle (if equipped) to FAST position and crank until engine starts.
WHEN OPERATING EQUIPMENT
• Do not tip the snowthrower at an angle which causes the fuel to spill.
• Do not choke the carburetor to stop the engine.
• Never run the engine with the air cleaner assembly (if equipped) or the air
filter (if equipped) removed.
WHEN CHANGING OIL
• If you drain the oil from the top oil fill tube, the fuel tank must be empty or
fuel can leak out and result in a fire or explosion.
WHEN TRANSPORTING EQUIPMENT
• Transport with fuel tank EMPTY, or with fuel shut-off valve OFF.
WHEN STORING GASOLINE OR EQUIPMENT WITH FUEL IN TANK
• Store away from furnaces, stoves, water heaters, or other appliances that have
pilot light or other ignition source because they can ignite fuel vapors.

fuel stabilizer (follow instructions on fuel stabilizer package). D
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.
use
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 engine starts.
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.
Start the engine as follows:
1. Check the oil level. See the “Check/Add Oil” section in the ENGINE
MANUAL.
2. Make sure equipment drive controls are disengaged.
3. Push the ON /OFF switch (A
, Figure 18) to the ON position.
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
WARNING: 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.
A clean-out tool (AA, Figure 23) 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.
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 adjusted 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.

AUGER SHEAR PIN REPLACEMENT
The augers are secured to the auger shaft with special shear pins that are
designed to break if an object becomes lodged in the auger housing. Use
of a harder grade shear pin will reduce the protection provided by the
shear pin.
WARNING: Do not go near the discharge chute or auger
when the engine is running. Do not run the engine if
any cover or guard is removed.
Under most circumstances, if the auger strikes an object which could
cause damage to the unit, the shear pin will break. This protects the gear
box and other parts from damage.
The shear pins (A
broken shear pin as follows.
1. Tap out the broken shear pin with a pin punch.
2. Install a new shear pin and cotter pin. Bend the ends of the cotter pin

Replacing Broken Shear Pin Figure 41
CHECK THE TIRES
Check tires for damage. Check the air pressure in the tires with an
accurate gauge (see Figure 42).
CAUTION: Avoid Injury! Explosive separation of tire
and rim parts is possible when they are serviced
incorrectly.
• Do not attempt to mount a tire without the proper
equipment and experience to perform the job.
• Do not inflate the tires above the recommended pressure.
• Do not weld or heat a wheel and tire assembly. Heat can
cause an increase in air pressure resulting in an
explosion. Welding can structurally weaken or deform the
