storing.
Operation
1. Do not put hands o r feet near rotating p arts, in the a uger/
impeller housing o r disc harge chu te. Cont act wit h the
rotating parts can am putate ha nds and feet.
2. The auger/impelle r clutch lev er is a safety de vice. Nev er
bypass its operati on. Doing so, makes the ma chine
unsafe and may cause p ersonal i njury.
3. The clutch leve rs must o perate easily in both d irections

transporting or not in use.
15. Never operate machine at high tran sport speeds on
slippery surfaces. Look down and b ehind an d use ca re
when in reverse.
16. If the machine should sta rt to vibrate a bnormally, stop th e
engine, disconnect the spark plug an d grou nd it agai nst
the engine. Inspect thoroughly for dam age. Repair any
damage before starting and ope rating.
17. Disengage all clutch lev ers and s top engin e before y ou
leave the operating position (be hind the handles). Wai t

check all compon ents a nd replace with orig inal
equipment manuf acturer’s (O.E.M. ) parts on ly. “Us e of
parts which do not meet the original equipment
specifications ma y lead t o imprope r performan ce and
compromise safety!”
6. Check clutch controls periodically to verify they engage
and disengage proper ly and adjust, if necessary. Re fer to
the adjustment sec tion in th is opera tor’s manual for
instructions.
7. Maintain or replace safety and instruction labels, as
necessary.

the augers. Pull the control handle back against the
upper handle to engage the augers; release to
disengage.

Located on right side of dash panel, the chute crank
determines the direction that snow will be discharged.
Turn clockwise to discharge snow to the left; turn
counterclockwise to discharge to the right.
Discharge Chute
The angle of the discharge chute controls the distance
that the snow is thrown. Tilt the discharge chute up for
greater distance; tilt down for less distance. Loosen the
hand knob on the side of the discharge chute to adjust.
Tilt the chute to the desired position, and tighten the
knob.

SECTION 4: OPERATING YOUR SNOW THROWER
Before Starting
WARNING: Read, understand, and follow
all instructions an d warnings on the machine
and in this manual before operating.
• The spark plug wire was disconnected for safety
purposes during assembly. Attach spark plug wire
to spark plug before starting.
Fuel And Oil Mixture
WARNING: Use extreme care when
handling gasoline. Gasoline is extremely
flammable and the vapors are explosive.
Never fuel machine indoors or while the
engine is hot or running. Extinguish cigarettes,
cigars, pipes and other sources of ignition.
Your snow thrower uses a two cycle engine that
requires a mixture of gasoline and two cycle engine
oil. Refer to the engine operator’s manua l for proper oil
and fuel recommendations.
• A plas tic cup was provided inside the fuel fill
opening on the fuel tank. Remove and discard this
cup before filling up the tank. Use the seperate fuel
tank cap to close after fill-up.
Starting Engine
• To start the engine of your snow thrower, follow the
starting instructions in the engine operator’s
manual.

Stopping Engine
• Run the engine for a few minutes before stopping to
help dry any moisture on the engine.
• To stop engine: Turn ignition key to OFF position
and remove it from the snow thrower.
IMPORT ANT :
Engine will not start without it.
• Wipe all snow and moisture from the unit. Move the
choke lever back and forth several times and leave
it in the ON position.
Keep the ignition key in a safe place.
Operating Tips
• Discharge snow downwind whenever possible.
Slightly overlap each previously cleared path.
• Lifting up on the handle will allow the rubber on the
augers to propel the snow thrower forward. Pushing
downward on the handle will raise the augers off
the ground and stop the forward motion.
NOTE: Excessive upward pressure on the handle will
result in premature wear on the rubber auger blades
which would not be covered by warranty.
• Run the engine for a few minutes before stopping to
help dry any moisture on the engine.
• Clean the snow thrower thoroughly after each use.
WARNING: Muffler, engine and surrounding
areas become hot and ca n cause a burn. Do
not touch.

SECTION 5: MAKING ADJUSTMENTS
WARNING: NEVER attempt to make any
adjustments while the eng ine is running, except
where specified i n the ope rator’s manual .
Shave Plate
• To check the adjustment of the shave plate, place
the unit on a leve l surface. See Figure 12. The
wheels, shave plate and augers should all contact
the level surface. Note that if the shave plate is
adjusted too high, snow may blow under the
housing. If the shave plate wears out excessively,
or the unit will not self-propel, the shave plate may
be adjusted too low.
NOTE: On new units or units with a new shave plate
installed, the augers may be slightly off the ground.
Augers
• To adjust, tip the snow thrower back so that it rests
on the handle. Loosen the lock nuts and bolts which
secure the shave plate to the housing. See Figure
13. Move the shave plate to desired position and
retighten the nuts and bolts. Make certain all nuts
and bolts are tightened securely.
