SECTION 6: MAINTAINING YOUR SNOW THROWER
General Recommendations
• Always observe safety rules when performing any
maintenance.
• The warranty on this snow thrower does not cover
items that have been subjected to operator abuse
or negligence. To receive full value from the
warranty, operator must maintain the snow thrower
as instructed in this manual.
• Some adjustments will have to be made
periodically to maintain your unit properly.
• All adjustments in the service and adjustments
sections of this manual should be checked at least
once each season.
• Periodically check all fasteners and hardware to
make sure these are tight.
Lubrication
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. Refer to Figure 10.
IMPORTANT:
Avoid spillage of oil on rubber friction
wheel and aluminum drive plate.
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 10.
IMPORTANT:
Keep all grease and oil off the rubber
friction wheel and drive plate.
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.
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 bolts
from the auger shaft and spray lubricant inside the
shaft. See Figure 13.
Figure 13
Auger Bearings and Shaft
• Every season lubricate the auger bearings and the
bearings on the side of the frame with light oil. See
to Figure 13.
Wheels
• Oil or spray lubricant into bearings at wheels at
least once a season. Pull klick pin, remove wheels,
clean and coat axles with a multipurpose
automotive grease. See Figure 14.

Engine
Refer to the engine manual for instructions.
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.
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 the spark plug
wire and ground it against the engine to
prevent unintended starting.
