SECTION 9: MAINTENANCE
WARNING:
Disconnect the spark plug
wire and ground against the engine
before performing any repairs or
maintenance.
AUGERS
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 16. If you
hit a foreign object or ice jam, the snow thrower is
designed so that the shear bolts will shear.
If the augers will not turn, check to see if the hex
bolts have sheared. Two 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.

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.
NOTE:
All models are equipped with reversible
skid shoes.
To remove skid shoes, remove the carriage bolts,
Belleville washers and hex nuts which attach them to
the snow thrower. Reassemble new skid shoes with
the carriage bolts, Belleville washers (cupped side
goes against skid shoes) and hex nuts.
To remove shave plate, remove the carriage bolts,
Belleville washers and hex nuts which attach it to the
