may be turned over to increase their lifespan.
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 Fig. 6-1.

Lubrication
Gear Shaft
The gear (hex) shaft should be lubricated at least once a season
or after every twenty-five (25) hours of operation.
1.
Allow the engine to run until it is out of fuel.
2.
Carefully pivot the snow thrower up and forward so that it
rests on the auger housing.
3.
Remove the frame cover from the underside of the snow
thrower by removing the self-tapping screws which secure
it. Refer to Fig 7-4.
4.
Apply a light coating of Regular Grade Anti-Seize to the hex
shaft. See Figure 6-2.
NOTE: When lubricating the hex shaft, be careful not to get
any anti-seize on the aluminum drive plate or the rubber
friction wheel. Doing so will hinder the snow thrower's
drive system. Wipe off any excess.
Figure 6-2
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 from the auger
shaft. Spray lubricant inside the shaft and around the spacers and
the flange bearings found at either end of the shaft.
See Fig. 6-3.
