Lubrication
A
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.
IMPORTANT: When lubricating engine or draining oil,
avoid dripping oil onto transmission parts.
Wheels
* Oil or spray lubricant into bearings at wheels at
least once a season. Pull klick pin, remove wheels,
dean and coat axles with a multipurpose
automotive grease. See Figure 15

Chute Directional Control
•
The worm gear on the chute control should be
lubricated with multipurpose automotive grease.
Auger Shaft
•
At least once a season, remove shear bolts on
auger shaft. Oil or spray lubricant inside shaft and
lubricate the auger bearings. See Figure 16.
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. Keep alt grease
and oil off the friction wheel and drive plate.
Drive and Shifting Mechanism
• Remove rear cover. Oil any chains, sprockets,
gears, bearings, shafts, and shifting mechanism at
least once a season. See Figure 17. Use engine oil
ora spray lubricant. Avoid getting oil on rubber
friction wheel and aluminum drive plate.
Gear Case
•
The worm gear case has been tilled with grease at
the factory. If disassembled for any reason,
lubricate with 2 ounces of shell grease.
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.
Friction Wheei
•
The rubber on the friction wheel is subject to wear
and should be checked after 25 hours of operation,
and periodically thereafter. Replace the friction
wheel rubber if any signs of wear or cracking are
found following instructions on page 18.
