SECTION 7: SERVICING YOUR SNOW THROWER
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.
Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If you hit a foreign object
or ice jam, the snow thrower is designed so that the
bolts may shear. See Figure 15.
If the augers do not turn, check if the bolts have
sheared. Two replacement shear bolts and hex lock
nuts have been provided with the snow thrower. Refer
to LoosePartson page 5.
IMPORTANT: NEVER replace the auger shear bolts with
standard hex bolts. Any damage to the auger gearbox
or other components, as a result of doing so, will NOT
be covered by your snow thrower's warranty.
ShavePlateandSkidShoes
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: The skid shoes on this machine have two wear
edges. When one side wears out, they can be rotated
180 ° to use the other edge.
