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.

To remove shave plate, remove the carriage bolts,
belleville washers and hex nuts which attach it to
the snow thrower housing. Reassemble new shave

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 bolts may shear.

Drain the gasoline from the snow thrower, or place
a piece of plastic film under the gas cap.
Tip the snow thrower up and forward so that it rests
on its auger housing.
Remove six self-tapping screws from the frame
cover underneath the snow thrower.
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 Loose Parts on page 5. For future use, order kit
number OEM-710-0890.
Roll the front and rear auger belts off the engine
pulley. See Figure 18.
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 coved by your snow thrower’s warranty.
