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.
DANGER
Fuel and its vapors are extremely flammable and explosive.
Always handle fuel with extreme care.
Failure to observe these safety instructions can cause a fire
or explosion which will result in severe burns or death.
Fuel Handling
Keep the area of operation clear of all persons, particularly small children
and pets.
Thoroughly inspect the area where the snowthrower will be used and remove
all doormats, sleds, boards, wires, and other foreign objects.

SNOW THROWING TIPS
.This snow thrower will propel itself for-
ward when the handle is raised enough
to cause the auger blades to contact the
ground. The auger will stop when control
switch lever is released.
.For most efficient snow throwing, turn the
discharge chute deflector to throw snow
downwind, and slightly overlap each
swath. In light snow take up to a full cut
and in heavy snow take less than a full
cut.
.The distance snow will be discharged
can be adjusted by moving the discharge
chute deflector. Raise the deflector for
more distance or lower the deflector for
less distance.
.In windy conditions, lower the chute de-
flector to direct discharged snow close to
the ground where it is less likely to blow
into unwanted areas.
.Keep the area to be cleared free of
stones, toys and other foreign objects for
safety and to prevent damage to the
snow thrower.
.Do not use the auger propelling feature
when clearing gravel or crushed rock
driveways. Move the handle down to
raise the auger slightly.
.The allowable forward speed of the snow
thrower is dependent on the depth and
weight of the snow. Experience will es-
tablish the most effective method of using
the snow thrower under different condi-
tions.
DRY AND AVERAGE SNOW
.Snow up to eight inch depth can be re-
moved rapidly and easily by walking at a
moderate rate. For snow or drifts of a
greater depth you may find it desirable to
slow your pace to allow the discharge
chute to dispose of the snow as rapidly
as the auger receives the snow.
.Plan to have the snow discharged in the
direction the wind is blowing.
WARNING: Always stand be-
hind snow thrower (operators
position) when starting motor.
Do Not put hands, feet, hair or loose
clothing on near the discharge chute de-
flector or auger housing while the motor
is running.
WARNING: Objects such as
gravel, rocks or other debris, if
struck by the auger, may be
thrown with sufficient force to cause per-
sonal injury or property damage.
Not for Reproduction
OPERATION
16
WET PACKED SNOW
Move slowly into snow of this condition. The
greater the depth, the slower you should go.
When it appears that the wet, packed snow
is causing the auger to slow down and the
chute to clog, back off and begin a series of
short jabs into the snow. These short back
and forth, 4 to 6 inch, jabbing motions will
“belch” the snow from the chute.
SNOW BANKS AND DRIFTS
In snow of greater depth than the unit, use
the ”jabbing” technique described above.
Turn the discharge chute away from the
snow bank. More time will be required to re-
move snow of this type than level snow.

TO ADJUST THE DRIVE BELT
If the motor drive pulley and the auger drive
pulley are not aligned properly, excessive
belt wear will occur. To check the pulley
alignment, proceed as follows:
1. Remove the belt cover (see “To Remove
Belt Cover”).
2. Place a straight edge approximately 16”
long across the large auger pulley, con-
tacting two points and extending to the
motor pulley (see Figure 13). The outside
of the motor pulley must be flush with the
straight edge. If the pulleys are aligned,
skip to the last step). Figure 13

MOTOR SERVICE
Motor repairs and adjustments should be
done by technicians trained to work on snow
thrower type motors. Take your snow throw-
er to an authorized service center for repair
and adjustment.
SNOW THROWER STORAGE
.Thoroughly clean the snow thrower.
.Lubricate all the lubrication points (see
the Maintenance section).
.Be sure that all nuts, bolts and screws
are securely fastened. Inspect all visible
moving parts for damage, breakage and
wear. Replace if necessary.
.Touch up all rusted or chipped paint sur-
faces; sand lightly before painting.
.Cover the bare metal parts of the blower
housing and auger with rust preventative,
such as a spray lubricant.
.Store the snow thrower indoors in a
clean, dry, locked-up place out of reach
of children.
.Store the extension cord with the snow
thrower to prevent misplacement.
.Inspect the snow thrower thoroughly for
worn, loose or damaged parts. Make all
necessary repairs before storing snow
thrower.
.Inspect extension cord thoroughly for
signs of excess wear or damage. If worn
or damaged, replace with a U.L. listed
cord suitable for outdoor use in cold
weather.
NOTE: A yearly checkup or tune-up at an
authorized service center is a good way
of ensuring that your snow thrower will
provide maximum performance for the
next season.
