Maintaining
Your Snow
Thrower
WARNING
Before lubricating,
repairing, or inspect-
ing, disengage all
controls and stop
engine. Wait until all
moving parts have
come to a complete
stop.
Keep all grease and oil
off of the rubber friction
wheel and aluminum
drive plate.
Engine
Refer to the separate engine manual packed with your
unit for all engine maintenance.
Lubrication
Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
Gear Shaft
The gear (hex) shaft should be lubricated at least once
a season or after every 25 hours of operation.
WARNING: Run the engine com-
pletely dry of gasoline before tipping
snowthrower.
1. Carefully pivot the snow thrower up and forward so
that it rests on the auger housing.
2. Remove the lower frame cover by removing the
screws which secure it.
3. Apply a light coating of an all-weather multi-purpose
oil to the hex shaft. See Figure 6-1.
NOTE: Avoid getting oil on rubber friction wheel and
aluminum drive plate.
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 6-2.
Augers
• The augers are secured to the spiral shaft with
shear pins and cotter pins. If the auger should strike
a foreign object or ice jam, the snow thrower is
designed so that the pins may shear. Refer to Figure
6-2.
• If the augers will not turn, check to see if the pins
have sheared. One set of replacement shear pins
has been provided with the snow thrower. When
replacing pins, spray an oil lubricant into shaft before
inserting new pins.
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 Figure 6-3.
