IMPORTANT:
To relieve pressure, always remove the
vent plug before lubricating the gear case. See Figure
14. Failure to do so could result in damage to the gear
case seals.
Figure 14
Discharge Chute
The base of the discharge chute and the spirals on the
chute crank should be lubricated at least every 25
hours of use. Apply the lubricant under the base of the
chute and where the spirals contact the discharge
chute. See Figure 15.
Figure 15
Drive and Shifting Mechanism
At least once a season or after every 25 hours of
operation, remove rear cover. Lubricate any chains,
sprockets, gears, bearings, shafts, and the shifting
mechanism at least once a season. Use engine oil or a
spray lubricant. Avoid getting oil on friction wheel and
aluminum drive plate. Refer to Figure 11.
Gear Shaft
Lubricate the gear shaft with 6-in-1 grease (part
number 737-0170) at least once a season, or after
every 25 hours of operation. Refer to Figure 11.
IMPORTANT:
Be careful not to allow grease to get on the
drive plate or friction wheel.
Traction Control / Auger Control Lock
The cams on the ends of the control rods which
interlock the traction drive and auger drive clutches
must be lubricated at least once a season or every 25
hours of operation using a multi-purpose automotive
grease. The cams can be accessed beneath the handle
panel. See Figure 16.

Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
Bonded Friction Wheel
Follow the instructions below to check the condition of
the bonded friction wheel every 25 hours of operation.
• Remove the six self-tapping screws from the frame
cover underneath the snow thrower.
• Visually inspect the bonded friction wheel 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. Refer to Figure 11.
• If it does not make contact, adjust the traction drive
cable and recheck the friction wheel.
• Replace bonded friction wheel if necessary. Refer
to instructions in Service Section on Page 17.
