TO THROW SNOW
CAUTION: HIDDEN HAZARDS may result in
minor or moderate injury and/or damage to
unit. Stay alert for holes, rocks, roots, traffic,
and other hazards.
To propel unit and throw snow:
1. Start engine.
2. Squeeze auger clutch bail against handlebar to
engage auger.
3. Lift handlebar so auger contacts surface to be
cleared. Lift the handlebar only high enough to
propel unit forward.
NOTE: Do not lift so high to allow snow to kick back
from under unit.
Tips for Operation
Snow is best removed as soon as possible after a snow
fall.
To clear an area, run unit in an overlapping series of
paths. For large areas; start in the middle and throw
snow to each side, so snow is not cleared more than
once.
ALWAYS direct snow away from area to be cleared and
with direction of the wind.
IMPORTANT: DO NOT overload unit capacity by
attempting to clear snow at too fast a rate.
TO TRAVEL TO ANOTHER WORK AREA
1. Release auger clutch bail to disengage auger.
2. Press down on handlebar enough to raise front of
unit slightly off the ground and push or pull unit.
TO TRANSPORT UNIT
Use extra care when loading or unloading unit onto
trailer or truck.
Secure unit chassis to transport vehicle. NEVER
secure by rods or linkages that could be damaged.
Always shutoff engine for transport.
FILLING THE FUEL TANK
Check fuel level by looking at fuel level indicator on rear
of unit. Add fuel as required.
WARNING: FLAMMABLE FUEL and its
EXPLOSIVE VAPORS can result in death or
serious injury.
Handle fuel with extreme care.
ALWAYS use an approved fuel container.
No Smoking! No Lighted Materials! No Open
Flames!
Allow engine to cool before any service.
ALWAYS clean up any spilled fuel.
To add fuel to fuel tank:
IMPORTANT: Two cycle engines require that oil be
mixed with fuel. Failure to mix oil with fuel will result in
seizure and severe damage to engine. DO NOT use
gasohol or gasoline containing alcohol because
alcohol will cause internal parts to deteriorate. See
Engine Manual for correct type and grade of fuel.
1. ALWAYS place unit in open or well ventilated area.
2. Stop engine and allow to cool.
3. See engine manual for proper fuel/oil mixture.
4. Clean fuel cap and surrounding area to prevent dirt
from entering fuel tank.
5. Remove cap.
6. Fill fuel tank with mixture. Tank capacity is 1.2
quarts (1.1 liters).
NOTE: Fuel mixture left standing for prolonged periods
will begin to separate; thoroughly shake mixture before
use.
7. Replace fuel cap and tighten.

CLEAN ENGINE COOLING SYSTEM
Engine is air cooled. Air must circulate freely around
engine to prevent overheating.
Every year (more often if conditions require) remove
cooling shrouds and clean cooling fins. Clean external
surfaces of engine of dust, dirt and oil deposits which
can contribute to improper cooling. Refer to Engine
Manual.
IMPORTANT: DO NOT operate engine with cooling
shrouds removed. Engine overheating and damage will
result.
CLEAN UNIT
After each use, brush snow and debris off with a soft
bristled brush. Occasionally apply a light coat of spray
lubricant to exposed metal joints and surfaces. Wipe off
excess with soft cloth. Do not use abrasives or harsh
cleaners.
IMPORTANT: Take steps to prevent rust and corrosion.
Never spray unit with water or store unit outdoors.
Water can seep into sealed bearings, which are sealed
against dirt and debris only, causing reduced
component life.

BRAKE MUST DISENGAGE when clutch is
engaged. BRAKE MUST STOP AUGER
WITHIN 5 SECONDS of releasing auger
clutch bail.
There must ALWAYS be some slight noticeable slack in
the auger control cable when the auger is disengaged.
This allows Extension Spring to pull idler Arm/Brake,
which applies the brake to the Belt.
The auger clutch bail should travel 6-3/4 to 7-1/4”
(17.1-18.4 cm) before contacting handlebar.
A properly adjusted clutch must extend control cable
Spring approximately 1/4 to 3/8” (6-10 mm) before
clutch bail contacts handlebar.
1. Shut off engine.
2. Loosen locknut on threaded section of control
cable adjusting feature.
3. Turn solid section to provide some slight,
noticeable slack in cable.
4. Hold the solid section with a pliers and gently, with

1/4 to 3/8”
1/4 - 3/8"
(6-10 mm)
TO ADJUST IDLER POSITION
The idler must be as close as possible to the drive belt
when the auger clutch is disengaged, but not so close
that it causes auger rotation.
WARNING: ROTATING PARTS can cut off
body parts. Keep hands and feet away. Loose
clothing, long hair or scarves can get caught
in rotating parts and cause death or serious
injury.
To adjust the idler position:
IMPORTANT: If adjustment cannot be achieved, the
Drive Belt must be replaced.
1. Shut off engine, allow to cool, and remove cowl.
2. Ensure control cable has some slight, noticeable
slack when auger clutch is disengaged (bail in
lowered position).
3. Ensure belt fingers are properly adjusted. See To
Adjust Belt Finger.
4. Loosen idler hardware, reposition idler along slot in
idler arm, and tighten hardware.
5. Check for proper extension of control cable spring.
See To Adjust Auger Control Cable.
6. Start engine and ensure auger does not rotate
when auger clutch is disengaged.
