operation of the snow thrower.
2. Squeeze the left hand auger drive clutch to
engage auger.
3. While the left hand auger drive clutch is
engaged, engage the right hand traction drive
clutch.
NOTE:
NEVER move shift lever without first
releasing the drive clutch.
TIRE CHAINS
(OPTIONAL)
Use tire chains when extra traction is necessary.

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.

adjusting the angle of the chute assembly. The
sharper the angle, the shorter the distance snow is
thrown.

Avoid these areas.
• For most efficient snow removal, remove
snow immediately after it falls.
• Discharge snow
possible. Slightly
swath.
• 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.
• Be certain to follow the precautions listed
under ''To Stop Engine'' in previous column to
prevent possible freeze-up.
• Clean the snow thrower thoroughly after each
use.
ADJUSTING SKID SHOE
The space between the shave plate and the ground
can be adjusted by adjusting the skid shoe. Slide the
skid shoe upwards and lower the housing to remove
snow close to the ground. Slide skid shoe
downwards and raise the housing to remove snow
from uneven ground like gravel. For more details,
refer to Adjusting the Skid Shoes in section 5.
ADJUSTING TRACTION DRIVE CLUTCH
Refer to the Final Adjustments section on page 10
for instructions to adjust the traction drive clutch. If
you are not sure whether you have been able to
adjust the traction drive clutch properly, check as
follows.
1. Drain the gasoline from the snow thrower or put
a plastic film under the gas cap if the snow
thrower has already been operated. Tip the
snow thrower forward onto the auger housing.
2. Remove the frame cover underneath the snow
thrower by removing the six self-tapping screws.
3. With the traction drive clutch released, check if
there is clearance between the friction wheel
and the drive plate in all positions of the shift
lever. For correct adjustment there has to be
enough clearance.
4. With the traction drive clutch engaged, check if
the friction wheel is contacting the drive plate.
