• Check the adjustment of the traction control as
instructed earlier. Repeat the previous steps to
provide more slack in the cable, in necessary.
If you are uncertain that you have reached the correct
adjustment, proceed as follows:
WARNING:
snow thrower's engine, and place a piece of
plastic film under the gas cap to avoid spillage
before beginning the job.
• Tip the snow thrower forward, allowing it to rest on
the auger housing.
• Remove the frame cover underneath the snow
thrower by removing six self-tapping screws.
• With the traction control released, make sure there
is clearance between the friction wheel and the
drive plate in all positions of the shift lever.
• With the traction control lever engaged, make sure
the friction wheel solidly contacts the drive plate.
See Figure 10.

If adjustment is necessary, adjust traction control as
instructed below:
• Thread the lock nut outward (down the coupler) to
provide more slack in the cable or thread the lock
nut inward (up the coupler) to provide less slack in
the cable. Refer to Figure 9
• Reattach the spring to the bracket.
• Reassemble the frame cover.
NOTE: If you placed plastic film under the gas cap, be
certain to remove it before operating the snow thrower.

Skid Shoe Adjustment
The space between the shave plate and the ground can
be adjusted by repositioning the skid shoes. For close
snow removal, as when using on a smooth concrete or
asphalt driveway, place the skid shoes in the low
position. Use the middle or high position when the area
to be cleared is uneven. When operating on gravel,
always put skid shoes in the high position.
See Figure 7.
Adjust skid shoes as follows:
• Loosen, but do not remove, the three hex nuts
which fasten the skid shoe to the auger housing.
• Raise or lower the skid shoe to desired position.
• Retighten the hex nuts loosened earlier.
• Repeat on the other side of the snow thrower.
NOTE: Make certain the entire bottom surface of skid
shoe is against the ground to avoid uneven wear on the
skid shoes.

Tire Pressure (Pneumatic Tires)
The tires are overinflated for shipping purposes.
• Check tire pressure. Maintain pressure between 10
and 14 psi.
NOTE: If the tire pressure is not equal in both tires, the
unit may pull to one side or the other.
WARNING:
any circumstance is 30 psi. Equal tire pressure
should be maintained at all times. Excessive
pressure (over 30 psi) when seating beads
may cause tire/rim assembly to burst with
force sufficient to cause serious injury.
