2.

To avoid possible freeze-up of starter
proceed as follows.
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 the starter.

3.

To stop engine, push the throttle lever all the 
way down, or remove the ignition key. Do not 
turn key. Disconnect the spark plug wire from 
the spark plug to prevent accidental starting 
while equipment is unattended.

NOTE: Do not lose ignition key. Keep it in a safe 
place. Engine will not start without the ignition key.

4.

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.

TO ENGAGE DRIVE

1.

With the engine running near top speed, move
shift lever into one of the six 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.

2.

Squeeze the left hand auger clutch grip against 
the handle to  engage it.

3.

While the left hand auger clutch grip is engaged, 
squeeze the right hand drive clutch grip.

4.

Release the left hand auger clutch grip only. The 
interlock mechanism should keep the left hand 
clutch engaged until the right hand clutch is 
released.

NOTE: NEVER move shift lever without first 
releasing the drive clutch.

TO STEER SNOWTHROWER

The trigger levers are located on the underside of 
the handles and are used to steer your snowthrower.
NOTE: The drive clutch must be engaged when 
using the triggers to steer the snow thrower.

1.

To turn right, squeeze the right trigger lever and
guide the snowthrower to the right.

2.

To turn left, squeeze the left trigger lever and 

guide the snowthrower to the left.

3.

Squeeze both triggers to transport the unit when 
the engine is not running.

NOTE: These controls should be used while 
operating your snowthrower in open areas until you 
become familiar with their operation.

TO ENGAGE AUGERS

To engage augers and start snow throwing action, 
squeeze the auger clutch grip against the left 
handle. Release to stop the augers (traction drive 
clutch grip must also be released).
The auger drive clutch can also be locked so you 
can turn the chute crank without interrupting the 
snow throwing process. Refer to “Traction Drive/ 
Auger Clutch Lock” in the Control section.

TIRE PRESSURE

1.

Tires are over-inflated for shipping purposes.
Reduce the tire pressure to 10-15 p.s.i. for
snowthrower operation. Use pneumatic tires only
on your snowthrower unit.

2.

Tire chains (optional equipment) should be used 
whenever extra traction is needed.

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

Temperature of muffler and 

surrounding areas may exceed 150

o

F. 

Avoid these areas.

1.

For most efficient snow removal, remove snow
immediately after it falls.

2.

Discharge snow downwind whenever possible. 
Slightly overlap each previous swath. The 
distance that snow is being thrown can be 
adjusted by altering the angle of the chute 
assembly. Sharper the angle, shorter the 
distance snow is thrown. 

3.

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.

4.

Be certain to follow the precautions listed under 
‘‘To Stop Engine’’ to prevent possible freeze-up.

5.

Clean the snow thrower thoroughly after each 
use.

WARNING: 

Never attempt to clean

chute or make any adjustments while
engine is running.
