use.
NOTE: Allow the engine to warm up for a few
minutes as the engine will not develop full power
until it reaches operating temperature.
SECTION 8: ADJUSTMENTS
WARNING: Never attempt to clean
chute or make any adjustments while
engine is running.
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 page 11.
ADJUSTING CHUTE
You can control the distance that snow is thrown by
adjusting the angle of the chute assembly. The
sharper the angle, the shorter the distance snow is
thrown.
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. To adjust the chute, loosen the hand knob. See
Figure 25.
2. Pivot the top of the chute assembly to the
position desired.
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

outside axle hole on the right side. This position
gives power drive to the left wheel only, making
the unit easier to maneuver.
Both Wheels Driving—Place klick pin in the hole in
the hub next to the rim on the right side. This
position is good for heavy snow as there is power
drive in both wheels.
