Check Friction Wheel Rubber
Follow the instructions below to check the condition of
the friction wheel rubber every 25 hours of operation.
• Remove the six self-tapping screws from the frame
cover underneath the snow thrower.
• Visually inspect the friction wheel rubber for
excessive wear, cracks, or loose fit on the friction
wheel drive hub.
• Also engage the traction control and check if the
friction wheel is making contact with the friction
plate.
• If it does not make contact, adjust the traction drive
cable following instructions and recheck the friction
wheel.
• Replace friction wheel rubber if necessary. Refer to
instructions in Service Section.
SECTION 7: SERVICING YOUR SNOW THROWER
WARNING: Before servicing, repairing, or
inspecting, disengage all clutch levers and
stop engine. Wait until all moving parts have
come to a complete stop. Disconnect spark
plug wire and ground it against the engine to
prevent unintended starting.
Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If you hit a foreign object
or ice jam, the snow thrower is designed so that the
bolts may shear. See Figure 16.
If the augers do not turn, check if the bolts have
sheared. Two replacement shear bolts and hex lock
nuts have been provided with the snow thrower. Refer
to Loose Parts on page 5.
IMPORTANT:
NEVER replace the auger shear bolts with
standard hex bolts. Any damage to the auger gearbox
or other components, as a result of doing so, will NOT
be covered by your snow thrower’s warranty.
Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the
snow thrower are subject to wear. They should be
checked periodically and replaced when necessary.
NOTE: The skid shoes on this machine have two wear
edges. When one side wears out, they can be rotated
180° to use the other edge.
• Remove the six carriage bolts (three per side), bell
washers and hex nuts which secure the skid shoes
to the snow thrower on either side. See Figure 12.
• Reassemble new skid shoes with the hardware
removed earlier (cupped side of bell washer against
the skid shoes). Make certain the skid shoes are
adjusted to be level. Refer to Figure 12.
• To remove the shave plate, remove the carriage
bolts, bell washers and hex nuts which secure the
shave plate to the snow thrower housing. See
Figure 16.

• Reassemble the new shave plate, making sure
heads of carriage bolts are to the inside of the
housing.
Replacing Belts
To remove and replace either the auger belt or the drive
belt, follow the steps below and then proceed to the
specific steps listed under respective sub-headings.
• Disconnect the chute crank assembly at the
discharge chute end by removing the hairpin clip
and the two flat washers.
• Remove the plastic belt cover, located near the
engine, by removing the three self-tapping screws
and flat washers that secure it. See Figure 17.
• Remove the large shoulder bolt and washer on the
left hand side of the engine pulley. See Figure 18.
Auger Belt
• Remove the cotter pin and washer from the ferrule
in order to disconnect the auger idler rod from the
brake bracket assembly. See Figure 19.
• Slip the auger control belt (the front belt) off the
engine pulley.
