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
