Shift Rod Adjustment
Skid Shoes
To adjust the shift rod, proceed as follows:
The space between the shave plate and the ground can
be adjusted. See Figure 11.
•
Remove the hairpin clip and slide the shift rod
connector up, to separate the upper shift rod from
the lower shift rod. See Figure 10.
•
For close snow removal on a smooth surface, raise
skid shoes higher on the auger housing.
Use a middle or lower position when the area to be
cleared is uneven.

Adjust skid shoes by loosening the four hex nuts
and carriage bolts. Move skid shoes to desired
position.
Make certain the entire bottom surface of skid shoe
is against the ground to avoid uneven wear on the
skid shoes. Retighten nuts and bolts securely.
•
•
Place the shift lever into the sixth (6) position.
Rotate the shift arm clockwise (from the operator’s
position) as far as it will go.
Thread the upper shift rod downward until the
elbow on its lower end aligns with the hole found in
the lower shift rod.
Reconnect the upper shift rod to the lower shift rod
by reinserting the hairpin clip removed earlier and
sliding the shift rod connector back down into place.

Carburetor
•
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
Refer to the separate engine manual, packed with
your unit, for carburetor adjustment information.
IMPORTANT: Make certain to check for correct
adjustment of the shift rod as instructed under Final
Adjustments in the Assembly Section, before operating
the snow thrower.
•
WARNING: If any adjustments need to be
made to the engine while the engine is
running (e.g. carburetor), keep clear of all
moving parts. Be careful of muffler, engine
and other surrounding heated surfaces.
Chute Assembly
The distance snow is thrown can be adjusted by
changing the angle of the chute assembly. To do so,
stop the engine by removing the ignition key and loosen
the plastic wing knobs found on either side of the
discharge chute. Pivot the chute upward or downward
before re-tightening the wing knobs.
Drive Wheels
•
The wheels may be adjusted for two different
methods of operation. Follow the steps below for
adjustment. See Figure 12.
