12 SECTION 2 — ASSEMBLY & SET-UP
Auger Control Lever
WARNING! Prior to operating
your unit, carefully read and
follow all instructions below.
Perform all adjustments to verify
your equipment is operating
safely and properly.
Refer to Controls & Operation section (page 16)
for the location of auger control lever and
check adjustment as follows:
1. When auger control lever is released and
in disengaged “UP” position, the cable
should have very little slack. It should
NOT be tight.
2. In a well-ventilated area, start the snow
thrower engine. Refer to your Engine
Operator’s Manual.
3. While standing in the operator’s position
(behind the unit), depress the auger
control lever to engage auger.
4. Allow auger to remain engaged for
approximately ten (10) seconds before
releasing auger control lever. Repeat this
several times.
5. With auger control lever in disengaged
“UP” position, walk to front of machine.
6. Confirm that auger has completely
stopped rotating and shows NO signs
of motion. If auger shows ANY signs
of rotating, immediately return to
operator’s position and shut OFF engine.
Wait for ALL moving parts to stop before
readjusting auger control lever.
7. To readjust the auger control cable,
loosen upper hex screw (a) on auger
control bracket. See Figure 2-37.
8. Position bracket upward to provide
more slack (or downward to increase

Tire Pressure
WARNING! Under any
circumstance do not exceed
manufacturers recommended
psi. Equal tire pressure should be
maintained at all times. Excessive
pressure when seating beads
may cause tire/rim assembly to
burst with force sufficient to
cause serious injury. Refer to
sidewall of tire for recommended
pressure.
The tires are over-inflated for shipping
purposes. Check tire pressure before
operating unit. Refer to tire side wall for tire
manufacturers recommended psi and deflate
(or inflate) tires as necessary.
NOTE: Equal tire pressure is to be maintained
at all times for performance purposes.
Adjustments
Skid Shoes
The snow thrower skid shoes are adjusted at
the factory set roughly 1/8” below the shave
plate. Adjust them downward, if desired, prior
to operating the snow thrower.
CAUTION: Use extreme caution
when on gravel and adjust auger
housing height to clear gravel or
crushed rock surfaces to avoid
picking up and throwing gravel or
crushed rock.
For close snow removal on a smooth
surface, raise skid shoes higher on auger
housing.
Use a lower position when area to be
cleared is uneven, such as a gravel
driveway.
NOTE: If you choose to operate unit on a
gravel surface, keep skid shoes in position for
maximum clearance between ground and
shave plate.
To adjust skid shoes:
1. Loosen four hex nuts (a) (two on each
side) and carriage bolts (b). Move skid
shoes to desired position.
See Figure 2-36.

NOTE: The skid shoes on your unit may
look slightly different (and have different
hardware) than ones shown in
Figure 2-36.
2. Make certain entire bottom surface of
skid shoe is against ground to avoid
uneven wear on skid shoes.
3. Retighten hex nuts (a) and
carriage bolts (b) securely.
