SECTION 6: MAINTAINING YOUR SNOW THROWER
WARNING: Before lubricating, 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.
Lubrication
Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
WARNING: If any adjustments need to be
made to the engine while the engine is
running (e.g. carburetor), keep clear of all
moving parts. Be careful of muffler, engine
and other surrounding heated surfaces.
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, or order part number 737-0170).
Refer to Figu re 10.
IMPORTANT: Keep all grease and oil off of the rubber
friction wheel and aluminum drive plate.
ChuteDirectional 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 it does not require checking. If disassembled for
any reason, lubricate with 2 ounces of Shell Alvania
grease EPR00, part number 737-0168. Before
reassembling, remove old sealant and apply new
sealant. See Figure 13.
To check the level of grease in the gear case, remove
the vent plug. If necessary, add grease using a grease
gun and the grease fitting on the side of the gear case.
IMPORTANT: Do not overfill the gear case, since
damage to the seals could result. Be sure the vent plug
is free of grease in order to relieve pressure.
AugerShaft
At least once a season, remove the shear bolts on the
auger shaft. Spray lubricant inside the shaft and
lubricate the plastic auger bearings at least once a
season. See Figure 13.

spray lubricant. Avoid getting oil on the friction
wheel rubber and aluminum drive plate. Refer to
Figure 10.
There is a grease fitting on the top of the axle shaft
which drives the rear track drive wheels on both sides
of the unit. Grease these fittings every 25 hours or once
a season.
TractionControl/ AugerControlLock
The cams on the ends of the control rods which
interlock the traction drive and auger drive controls
must be lubricated at least once a season or every 25
