turn key. Disconnect the spark plug wire from the
spark plug to prevent accidental starting while
equipment is unattended.
To prevent starter freeze-up:
•Run engine for a few minutes before stopping to
help dry off any moisture on the engine.
•Electric Starter: Connect power cord to switch
box on engine, then to 120 volt AC receptacle.
With the engine running, push starter button and
spin the starter for several seconds. The unusual
sound made by spinning the starter will not harm
engine or starter. Disconnect the power cord from
receptacle first, and then from switch box.
•Recoil Starter: With engine running, pull starter
rope with a rapid, continuous full arm stroke three
or four times. Pulling the starter rope will produce
a loud clattering sound, which is not harmful to
the engine or starter.
•Wipe all snow and moisture from the carburetor
cover in the area of the control levers. Also, move
control levers back and forth several times. Leave
throttle control lever in the STOP or OFF position.
Leave choke control in the FULL choke position.
•Remove ignition key and disconnect spark plug
wire. Do not turn key.
IMPORTANT: Do not lose ignition key. Keep it in a safe
place. Engine will not start without the ignition key.
To Engage Drive
•With the engine running near top speed, move
shift lever into one of the five FORWARD
positions or two REVERSE positions. Select a
speed appropriate for the snow conditions that
exist. Use the slower speeds until you are familiar
with the operation of the snow thrower.
•Squeeze the auger control and the augers will
turn. Release it and the augers will stop.
•Squeeze traction control and the snow thrower
will move. Release it and unit will stop. Never
move shift lever without releasing traction control.
To Engage Augers
•To engage augers and start throwing snow,
squeeze the auger control against the left handle.
Release to stop the augers.
Tire Chains (Optional Equipment)
•Tire chains should be used whenever extra
traction is needed. If your unit is not equipped
with tire chains, you may purchase them.
Operating Tips
NOTE: Allow the engine to warm up for a few minutes
as the engine will not develop full power until it
reaches operating temperature.
WARNING: The muffler, engine and their
surrounding areas become hot and can
cause a burn. Do not touch.
•Discharge snow downwind whenever possible.
Slightly overlap each previous path.
•Set the skid shoes 1/4" below the scraper bar for
normal usage. The skid shoes may be adjusted
upward for hard-packed snow. Adjust downward
when using on gravel or crushed rock.
•Avoid possible starter freeze-up. Clean the snow
thrower thoroughly after each use.
SECTION 5: MAKING ADJUSTMENTS
WARNING: NEVER attempt to make
any adjustments while the engine is
running, except where specified in the
operator’s manual.
Chute Assembly
The distance snow is thrown can be adjusted by
changing the angle of the chute assembly. Refer to
Chute Tilt Control on page 10.
Skid Shoe
The space between shave plate and ground can be
adjusted by raising or lowering the skid shoes. Refer
to Skid Shoe Adjustment on page 15.
Traction Control
Refer to Final Adjustments on page 9 to adjust
traction control. If you are want to check further for
correct adjustment, proceed as follows:
WARNING: Drain the gasoline out of
snow thrower engine, place a piece of
plastic film under the gas cap to avoid
spillage before beginning the job.
•Tip the snow thrower forward, allowing it to rest
on the auger housing.
•Remove the frame cover underneath the snow
thrower by removing six self-tapping screws.

13
•With the traction control released, there must be
clearance between the friction wheel and the
drive plate in all positions of the shift lever.
•With traction control engaged, the friction wheel
must contact the drive plate. See Figure 16.
Figure 16
If adjustment is necessary:
•Loosen the jam nut on the traction drive cable
and thread the cable in or out as necessary.
•Retighten the jam nut to secure the cable when
correct adjustment is reached.
•Reassemble the frame cover.
NOTE: If you placed plastic film under the gas cap, be
certain to remove it before operating the snow
thrower.
Auger Control
Refer to details on page 9 to adjust the auger
control.
Shift Rod
To adjust the shift rod, proceed as follows.
•Remove the hairpin clip and flat washer from the
shift handle under the handle panel.
•Place shift lever in sixth (6) position or the fastest
forward speed.
•Push shift arm assembly down as far as it will go.
•Rotate the ferrule up or down on the shift rod as
necessary until the ferrule lines up with the upper
hole in the shift lever. See Figure 17.
•Insert ferrule into the upper hole in shift lever.
•Reinstall the hairpin clip and the washer.
IMPORTANT: Check for correct adjustment of the shift
lever rod as instructed on page 9, before operating
the snow thrower.
Figure 17
Drive Wheels
The wheels may be adjusted for two different
methods of operation. The adjustment is made by
placing the click pins in one of two different holes on
the right side of the unit. See Figure 18.
One Wheel Driving: Insert the click pin only
through the outside hole of the axle (not the rim)
on the right side of the snow thrower. This posi-
tion gives power drive to the left wheel only, mak-
ing the unit easier to maneuver.
Both Wheels Driving: Insert the click pin
through the hole in the hub of the rim and the
inside hole on the snow thrower’s right axle. This
position is good for heavy snow as there is power
drive in both wheels.
Figure 18
IMPORTANT: Never operate the snow thrower with the
click pin inserted through both the rim and the outside
hole in the axle. Doing so can result in serious
damage to the drive system.
