SECTION 6: MAINTAINING YOUR SNOW THROWER
WARNING: Before lubricating, repairing,
or inspecting, disengage all controls 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.
Always wear safety glasses during
operation or while performing any
adjustments or repairs.
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 Figure 9.
IMPORTANT:
Keep all grease and oil off of 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 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 12.
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.
Auger Shaft
At least once a season, remove the shear pins on the
auger shaft. Spray lubricant inside the shaft and
lubricate the plastic auger bearings at least once a
season. See Figure 12.
Figure 12
Auger Bearings
Every season lubricate the auger bearings and the
bearings on the side of the frame with light oil. See
Figure 12.
Drive and Shifting Mechanism
Lubricate at least once a season or after every 25 hours
of operation. Remove the rear cover, lubricate any
chains, sprockets, gears, bearings, shafts, and shifting
mechanism at least once a season. Use engine oil or a
spray lubricant. Avoid getting oil on the friction
wheel rubber and aluminum drive plate. Refer to
Figure 9.
Drive / Auger Control Lock
The cams on the ends of the control rods which
interlock the drive and auger controls 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.
