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.
There is a grease fitting on the top of the axle shaft
which drives the rear track drive wheels on both sides
of the unit. Grease these fittings every 25 hours or once
a season.
Chute Directional Control
The spiral on the end of the chute directional control
and the base of the discharge chute itself should be
lubed with multi-purpose automotive grease once a
season. See Figure 12.

Traction Control / Auger Control Lock
The cams on the ends of the control rods which
interlock the traction drive and auger drive 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.
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 and grease the fittings on the end of the auger
shaft with a standard grease gun. See Figure 13.

Gear Case
The gear case is equipped with a grease fitting on the
left housing and should be lubricated with Shell Alvania
grease EPR00, part number 737-0168 every 25 hours.
See Figure 13.
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.
Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
IMPORTANT: When following instructions in separate
engine manual for draining oil, be sure to protect frame
to avoid oil dripping onto transmission parts.
SECTION 7: SERVICING YOUR SNOW THROWER
WARNING: Before servicing, 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.
Engine
Refer to the separate engine manual packed with your
unit for all engine maintenance procedures.
Augers
• The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If you hit a hard
foreign object or ice jam, the snow thrower is
designed so that the bolts may shear.
Refer to Figure 13.
• If the augers will not turn, check to see if the bolts
have sheared. Replacement shear bolts and hex
lock nuts have been provided with the snow
thrower. When replacing bolts, spray an oil
lubricant into shaft before inserting new bolts.
