OPERATION
Auger Clutch Bail
WARNING: AVOID INJURY. Read
and understand Operational
Safety Rules and Fuel Safety
Rules before proceeding.
WARNING: IMPROPER
ADJUSTMENT could result in
death or serious injury. AUGER
BRAKE MUST DISENGAGE
when clutch is engaged. BRAKE
MUST STOP AUGER WITHIN 5
SECONDS of releasing auger
clutch bail.
CONTROLS AND FEATURES
Refer to Figure 1 for controls and features
locations.
Ignition Switch
The ignition switch is operated with a
removable key that has two positions.
STOP
RUN
OS1680
Squeeze the auger
clutch bail against the
handlebar to engage
auger.
"STOP" Position: Ignition
system is shut down.
"RUN" Position: All controls
are operable.
To start the engine, the key
must be in the "RUN" position.
To stop the engine, turn the
key to the "STOP" position.
Auger
When handlebar is lifted so auger contacts the
ground, auger propels unit forward while
collecting snow. Forward speed will vary
according to depth and moisture content.
Engaged
Disengaged
Release bail to
disengage and brake
auger.
OS1562
IMPORTANT: Check auger to be sure it is not
frozen. If belt squeals when clutch bail is
engaged, auger is frozen. Immediately release
the clutch bail and move the unit to a heated
area to thaw.
GB - 11
Discharge Chute Deflector
IMPORTANT: Check clutch/brake function
before each use. If auger clutch bail moves
freely with no resistance before contacting
handlebar, adjust or repair unit before
operating.
Primer Bulb
Push in the primer bulb to add
fuel for easier engine start. See
Starting and Shut Off.
OS1620
Choke Control Knob
OS1570
The discharge chute deflector controls how
high snow is thrown.
Use handle at rear of deflector to position
deflector at desired height.
Push down handle to increase height of
discharge.
Pull up on handle to decrease height of
discharge.
IMPORTANT: If chute deflector does not stay
in set position, adjust as directed in To Adjust
Discharge Chute Deflector, or repair before
operation.
Handlebars
When pulled out (away from
auger housing) the choke
control knob chokes off air to
the engine for easier start.
When pushed in, control knob
allows for normal operation.
IMPORTANT: When engine has started, open
choke slowly by gradually pushing choke
control in.
Recoil Starter Handle
When pulled, handle will crank engine.
IMPORTANT: DO NOT let handle snap back
against unit.
Discharge Chute
Discharge Chute rotates 220°. Rotate chute
with discharge chute handle.
Chute Crank Handle (938017, 018)
Rotate the Chute with Discharge Chute Crank
Handle (Figure 8).
IMPORTANT: DO NOT force frozen Chute
controls. Start engine and run for 3-5 minutes
to thaw. If still frozen, take to warm place until
controls are free.
Adjust upper handlebar by selecting alternate
holes for "J" Bolts.
CAUTION: Adjust auger control
cable after changing handlebar
height.
Tighten handlebar knobs to secure upper
handlebar.
The upper handlebar can be folded for
storage.
Scraper Blade
The scraper blade allows the back of the
housing to keep better contact with the surface
being cleared. It also prevents damage to the
housing from normal wear.
IMPORTANT: DO NOT allow scraper blade to
wear down too far or auger housing will
become damaged.

engine to adjust to the outdoor temperatures
before clearing snow. Before shut off, run
auger a few minutes to prevent freeze-up of
auger.
NOTE: Try out each control without the engine
running to see how it works and what it does.
WARNING: THROWN
OBJECTS could cause death or
serious injury. ALWAYS position
discharge chute straight ahead
(away from operator) for starting.
• If you cannot pull starter handle, auger is
frozen. Move unit to a heated area to thaw
to prevent possible damage.
2. Check Clutch Function
Manual Start
WARNING: FAILURE OF
CLUTCHES OR BRAKES may
result in death or serious injury.
Check clutch and brake function
before each use. Repair or
adjust before operation.
1. With key in "STOP" position, squeeze
auger clutch bail to Engaged position.
2. Pull recoil starter handle. Auger should
rotate with the turning of the engine.
3. Release the auger clutch bail.
4. Pull recoil starter handle again. Auger
must not rotate as engine turns.
If the auger clutch bail moves freely with no
resistance before contacting handlebar, adjust
or repair before operation( see To Adjust
Auger Control Cable).
1. Turn discharge chute straight ahead.
2. Push primer bulb 1 to 3 times for cold
engine.

stroke. Let rope rewind slowly.
IMPORTANT: DO NOT let starter handle snap
against unit.
8. Repeat until engine starts. (If engine does
not start, refer to Troubleshooting.)

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
Shutoff
1. Engage and run auger a few minutes
after use to prevent freeze-up of auger.
2. Release auger clutch bail and allow auger
to stop.
3. Turn ignition switch to "STOP" position.
4. Remove key.
TO THROW SNOW
IMPORTANT: Allow unit and engine to adjust
to the outdoor temperature before clearing
snow.
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.

WARNING: IMPROPER
ADJUSTMENT could result in
death or serious injury. AUGER
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 in (17.1-18.4 cm) before contacting
handlebar.
A properly adjusted clutch must extend control
cable spring approximately 1/4 in to 3/8 in
(6-10 mm) before clutch bail contacts
handlebar (Figure 12).
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 a small wrench, tighten the
locknut.
IMPORTANT: If there is still no resistance, the
idler position must be adjusted. See To Adjust
Idler Position.
