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.
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 Adjusting the Skid Shoes in section 5.
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
1. To adjust the chute, loosen the hand knob. See
Figure 25.
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
