Setup and
Adjustment
WARNING

plug wire and ground it
against the engine to
prevent unintended
starting.
Do not use the chute
handle to lift the snow
thrower.
Over-inflating the tire with
excessive pressure (well
above 20 psi) may cause
the tire/rim to burst with
sufficient force to cause
serious pressure.
All references to left
or right side of the snow
thrower is from the
operating position only.
IMPORTANT: This unit is shipped with the engine full of
oil. After assembly, see Operation section for fuel and
oil details.

Clean-Out Tool
This tool and the electric extension cord, if so equipped,
may be fastened with a cable tie to the rear of the auger
housing for shipping purposes. In that case, cut the
cable tie and remove the extension cord now.
Final Adjustments
IMPORTANT: Check the adjustments as instructed and
make any final adjustments necessary before operating
the unit. Check all nuts and bolts for tightness. Failure to
follow these instructions may cause damage to unit.
Tire Pressure
The proper inflation pressure is 20 psi. Check the tire
pressure periodically and maintain equal pressure in both
tires at all times. Excessive pressure (well above 20 psi)
may cause the wheel (tire/rim) assembly to burst with
sufficient force to cause serious injury. Do not over-inflate
the tire. Use a manual pump or portable electric tire
inflator to prevent over-inflation. NEVER USE AN AIR
COMPRESSOR.
