cleaning, lubricating
or performing any
kind of maintenance
or adjustment on
your machine.

Engine
Refer to the separate engine manual packed with your
unit for all engine maintenance.
Lubrication
Gear (Hex) Shaft
Once a season, lubricate the hex shaft with a penetrat-
ing oil, but not grease. Refer to Figure 17.
Wheels
At least once a season, remove both wheels. Clean and
coat the axles with a multipurpose automotive grease
before reinstalling wheels.
Auger Shaft
At least once a season, remove the shear pins on auger
shaft. Spray lubricant inside shaft, around the spacers.
Also lubricate the flange bearings found at either end of
the shaft. See Figure 24.
Gear Case
The auger gear case has been filled with grease at
the factory. If disassembled for any reason, lubricate
with two ounces of grease (Part Number 737-0168).
Before reassembling, remove old sealant and apply new
sealant.
NOTE:
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.
Drive Mechanism
Remove rear cover. Oil 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 rubber friction wheel and aluminum drive
plate.
Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
Drive/Auger Control Lock
The cam on the ends of the control rods which interlock
the drive and auger controls must be lubricated at least
once a season or every 25 hours of operation using
a multi-purpose automotive grease. The cam can be
accessed beneath handle panel.
Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the
snow thrower are subject to wear. They should be
checked periodically and replaced when necessary.
To remove skid shoes:
1. Remove the four carriage bolts and hex flange nuts
which secure them to the snow thrower.
2. Reassemble new skid shoes with the four carriage
bolts (two on each side) and hex flange nuts. Refer
to Figures 18A or 18B.

sure heads of carriage bolts are to the inside of
housing. Tighten securely.
