needed. Call our Customer Support Department, as
instructed on Page 2, for information on tire chains and
other optional accessories.
Operating Tips
NOTE: Allow the en gine to warm up for a few mi nutes
as the engine will not develop full power until it reaches
operating temperature.
WARNING: Temperature of muffler and
surrounding areas may exceed 150
these areas.
•For most efficien t snow r emoval, re move sno w
immediately after it falls.
•Discharge snow downwind whenever possible.

Drive Wheels
The wheels may be adjusted for two different methods
of operation. The adjustment is made by placing the
click pins in one of two different holes on the right side
of the unit. See Figure 16.
One Wheel Driving—Insert the click pin only
through the outside hole of the axle (not the rim) on
the right side of the snow thrower. This position
gives power drive to the left wheel only, making the
unit easier to maneuver.
Both Wheels Driving—Insert the click pin through
the hole in the hub of the rim and the inside hole on
the snow thrower’s right axle. This position is good
for heavy snow as there is power drive in both
wheels.
IMPORT ANT :
