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:
Remove the four carriage bolts and hex flange nuts which
1.
secure them to the snow thrower.
Reassemble new skid shoes with the four carriage bolts
2.
(two on each side) and hex flange nuts. Refer to Fig. 6-1.
To remove shave plate:
Remove the carriage bolts and hex nuts which attach it to
1.
the snow thrower housing.
Reassemble new shave plate, making sure heads of carriage
2.
bolts are to the inside of housing. Tighten securely.
Tire Pressure
Before operating, check tire pressure and reduce pressure to
between 15 psi and 20 psi.
If the tire pressure is not equal in both tires, the unit may pull to
one side or the other.
Lubrication
Gear Shaft
The gear (hex) shaft should be lubricated at least once a season
or after every twenty-five (25) hours of operation.
Allow the engine to run until it is out of fuel.
1.
Carefully pivot the snow thrower up and forward so that it
2.
rests on the auger housing.
Remove the frame cover from the underside of the snow
3.
thrower by removing four self-tapping screws which secure
it. Refer to Fig 8-3.
Apply a light coating of engine oil (or 3-in-1 oil) to the hex
4.
shaft. See Fig. 6-2.
NOTE:
When lubrication the hex shaft, be careful not to get
any oil on the aluminum drive plate or the rubber friction
wheel. Doing so will hinder the snow thrower’s drive
system. Wipe off any excess or spilled oil.
Wheels
At least once a season, remove both wheels. Clean and coat the
axles with a multipurpose automotive grease before reinstalling
wheels.
Chute Directional Control
Once a season, lubricate the eye-bolt bushing and the spiral with
3-in-1 oil.
