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 the spark
plug wire and ground it against the engine to
prevent unintended starting.
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.
• Periodically check all fasteners and hardware to
make sure they are tight.
Lubrication
Drive and Shifting Mechanism
• At least once a season or after every 25 hours of
operation, remove rear cover. Lubricate all chains,
sprockets, gears, bearings, shafts, and the shifting
mechanism. Use engine oil or a spray lubricant.
Refer to Figure 12.
IMPORTANT: Keep all grease and oil off the rubber
friction wheel and drive plate.
Auger Gear Case
The auger gear case is lubricated with grease at the
factory and it does not require checking. If disassem-
bled 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, use a spray lubricant to
lubricate the auger shaft inside the auger spiral
hubs and spiral spacers. The bowtie cotter pins and
shear pins may be removed to aid in lubricating the
spiral hubs. Spray lubricant inside hub and spin the
auger spiral by hand to disperse the lubricant. See
Figure 14.
Figure 14
Discharge Chute
The base of the discharge chute and the worm coil 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 coil contacts the discharge chute.
See Figure 15.
Figure 15
Auger Bearings and Shaft
• Every season lubricate the auger shaft bearing at
each end of the shaft. See to Figure 14.
• Lubricate the bearings on the side of the frame with
a light oil. From inside the wheels, spray lubricant
into the bearings at least once a season.
• Remove the wheels, one side at a time, and clean
and coat axles with multi-purpose automotive
grease.
