SECTION 8: SERVICE
WARNING:
Before servicing, repairing, or
inspecting, disengage all clutch levers and
stop engine. Wait until all moving parts have
come to a complete stop. Disconnect spark
plug wire and ground it against the engine to
prevent unintended starting.
Engine
•
Refer to the engine manual for all engine
maintenance procedures.
Augers
•
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 22. If you
hit a hard foreign object or ice jam, the snow
thrower is designed so that the bolts may shear.
•
If the augers will not turn, check to see if the bolts
have sheared. 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.

•
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, cupped washers and hex nuts which attach
them to the snow thrower. Reassemble new skid
shoes with the four carriage bolts, cupped washers
(cupped side goes against skid shoes) and hex
nuts. See Figure 24.
