SECTION 7: MAINTAINING YOUR SNOW THROWER
WARNING: Before lubricating, repair-
ing, or inspecting, disengage all clutch
levers and stop engine. Wait until all mov-
ing 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: When following instructions
in the engine manual for draining oil, be
sure to protect frame to avoid oil dripping
onto transmission parts.
Gear Shaft
• Lubricate the gear shaft with a good all-weather
multi-purpose light grease at least once a season or
after every 25 hours of operation.
IMPORTANT:
Keep all grease and oil off the friction
wheel and drive plate.
Chute Directional Control
• The worm gear on the chute directional control
should be greased with multipurpose automotive
grease.
Wheels
• Oil or spray lubricant into bearings at least once a
season. Pull the klick pins and remove wheels,
clean and coat axles with a multipurpose
automotive grease. See Figure 18.
Figure 18
Auger Shaft
At least once a season, remove the shear bolts on the
auger shaft. Spray lubricant inside the shaft. Also
lubricate the plastic auger bearings at least once a
season on the end of the auger shaft with a standard
grease gun. See Figure 19.
Gear Case
• The worm gear case has been filled with grease at
the factory. If disassembled for any reason,
lubricate with 2 ounces of shell grease, part number
737-0168.
IMPORTANT:
Do not overfill the gear case. Damage to
the seals could result. Be sure the vent plug is free of
grease in order to relieve pressure.

gears, bearings, shafts, and shifting mechanism at
least once a season. Use engine oil or a spray
