SAFETY STANDARDS
REQUIRE OPERATOR PRESENCE CONTROLS
TO MINIMIZE THE
RISK OF INJURY. YOUR SNOW THROWER IS EQUIPPED WITH SUCH CONTROLS. DO NOT
AI-FEMPT TO DEFEAT THE FUNCTION OF THE OPERATOR PRESENCE CONTROL UNDER
ANY CIRCUMSTANCES.
TRAINING
1.
2.
Read the operator's
manual carefully. Be
thoroughly familiar with the controls and the
proper use of the snow thrower. Know how to
stop the snow thrower and disengage the
controls quickly.
Never allow children to operate the snow thrower
and keep them away while It Is operating. Never
allow adults to operate the snow thrower without
proper Instruction. DO not carry passengers.
3.
Keep the area of operetlon clear of all persons,
particularly small children, and pets.
4.
Exercise caution to avoid slipping or falling,

crushed rock surfaces,
7.
Never aftempt to make any edjustmsnts while the
engine (motor)
Is running
(except when
specifically recommended by the manufacturer).
8.
Let engine (motor) and snow thrower adjust to
outdoor temperatures before starting to clear
SNOW.

Always weer safety glasees or eye shields du ring
operetlon or while performing an adjustment or
repair to protect eyes from foreign objects that
may be thrown from the snow thrower.
OPERATION
1. Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at all
times.
PREPARATION
1. Thoroughly Inspect the area where the snow
thrower Is to be used and remove all doormats,

for hidden hazards or traffic.
3.
After striking a foreign object, stop the engine
(motor), remove the wire from the spark plug,
disconnect
the cord on electric

6.
When cleaning, repairing, or Inspecting, make
cartaln the auger/impeller and all moving parts
have stopped. Disconnect the spark plug wire
and keep the wire away from the plug to prevent
accidental starting.
Take all possible precautions when leaving the
snow thrower unattended. Disengage the auger/
Impeller, shift to neutral, stop engine, and
remove key.
(d) Replace fuel tank cap securely and wipe up
spilled fuel.
(e) Never store fuel or snow thrower with fuel In
the tank Inside of a building where fumes may
reach an open flame or spark.
(f) Check fuel supply before each use, anowlng
space for expenslonas the heatofthe engine

MAI'NTENANCE AND STORAGE
DO not run the engine indoors, except when starting
the engine and for transporting the snow thrower In
or out of the building. Open the outside doors;
exhaust fumes are dangerous (containing CARBON
MONOXIDE, an ODORLESS and DEADLY GAS).
1.
Check shear bolts and other bolts at frequent
improper tightness to be sure the snow thrower
is In safe working condition.
2. Never store the snow thrower with fuel in the fuel
tank inside a building whers Ignition sourcee are
present such as hot water and space heaters,
clothes dryers, and the llke. Allow the engine to
cool before storing In any enclosure.
Do not clear snow across the face of slopes.
Exercise caution when changing direction on
slopes. Do not attempt to clear steep slopes.
10. Never operate the snow thrower without proper
guards, plates or other safety protective devices
In place.
11. Never operate the snow thrower near glass
enclosures,
automobiles,
window
wells,
drop-offs, and the like wit hour proper adjustment
of the snow discharge angle. Keep children and
pets away.
12. Do not overload the machine
capacity
attempting to clear snow at too fast a rate.
3.
Always •refer to operator's manual instructions
for Important details If the snow thrower is to be
stored for an extended period.
4.
Maintain or replace safety and Instruction labels,
as necessary.
Run the snow thrower a few minutes after
throwing snow to prevent freeze-up of the auger/
impeller.

WARNING
This snow thrower Is for use on sidewalks,
driveways, and other ground level surfaces.
14. Never direct dlscherge at bystanders or allow
anyone In front of the snow thrower.
CAUTION should be exercised while using on
steep sloping surfaces. DO NOT USE SNOW
THROWER ON SURFACES ABOVE GROUND
LEVEL such as roofs of residences, garages,
porches or other such structures or buildings.
15. Disengage power to the augerllmpeller when

SKID MOUNTING NUTS
TO ADJUST SKID HEIGHT
Thissnowthroweris equippedwithtwo heightadjustment
skids,located on the outside of the auger housing(See
Fig. 20).These skidselevatethefront of thesnowthrower.
AUGER HOUSING
For normalhard sudaces, adjustthe skids as follows:
•
Check tirepressure(14 to 17 pounds).See sideoftire
for maximuminflation.Do notexceed maximumpressure on side of tire.
•
Place the extra shear bolts supplied (found in parts
bag) under each end of the scraperbar near but not
underthe skid.
•
Loosen the skid mounting nuts (See Fig. 20) and
adjust the skids up to bring the front of the snow
throwerdown. Re-tightenthe mounting nuts.
•
Set the skid on the other side at the same height.

Forrockyor uneven surfaces,adjustthe skidsas follows:
•

the skids shouldalwaysbe adjustedto allow1/8" between
the scraperbar and the sidewalkor area to be cleaned.
The scraper bar may have to be returned to its original
lowersettingto maintaintheoriginalperformancelevel.To
adjust:
•
Positionthe snow thrower on a level sudace.
•
Make sure both tires are equally inflated.
•
Loosen the carriage bolts and nuts securing the
scraperbar to the auger housing.
•
Adjustthe scraper bar to the properposition.
•
Tightenthecarriage bolts and nuts,making sure that
the scraperbar is parallelwith the workingsurface.
•
Loosen both 1/2" nuts on the crank adjusting rod
(using3/4" wrenches).
•
Rotate the adjustingrod in or out to allowabout 1/8"
clearance between the notch in the flange and the
outerdiameter of the worm.
•
Once this clearance is set, tigtltenthe nuts.
NOTE: Be sure the crank does not touchthe side of the

TO REPLACE AUGER SHEAR BOLT
The augers are secured to the auger shaft with special
bolts (See Fig. 33) that are designed to break (to protect
the machine) if an object becomes lodged in the auger
