Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
Gear Shaft
Lubricate the gear shaft with 6-n-1 grease at least once
a season or after every 25 hours of operation (available
at automotive stores). Refer to Figure 26.
IMPORTANT:
Keep all grease and oil off the rubber
friction wheel and aluminum drive plate.
Chute Directional
Control
The worm gear on the chute directional control should
be greased with multipurpose automotive grease.
Gear Case
The gear case is lubricated with grease at the factory
and does not require checking. If it is disassembled for
any reason, lubricate with 2 ounces of Shell Alvania
grease EPR00. Before reassembling, remove old
sealant and apply new sealant.
Drive Control / Auger Control Lock
The cams on the ends of the control rods which
interlock the drive control and auger control must be
lubricated at least once a season or every 25 hours of
operation. The cams can be accessed beneath the
handle panel. Use a multi-purpose automotive grease.
See Figure 14.

Check Friction Wheel
Follow instructions below to check the condition of the
friction wheel rubber every 25 hours of operation.
1.
Remove the four self-tapping screws from the
frame cover underneath the snow thrower.
2.
Visually inspect the friction wheel rubber for
excessive wear, cracks, or loose fit on the friction
wheel drive hub.
3.
Also engage the drive control and check if the
friction wheel is making contact with friction plate. If
it does not make contact, adjust the drive control
cable and recheck the friction wheel.
