WARNING:
If any adjustments are made to
the engine while the engine is running (e.g.
carburetor), keep clear of all moving parts. Be
careful of heated surfaces and mufflers.
Minor carburetor
adjustments
may be required to
compensate
for differences
in fuel temperature,
altitude
and load.
Service
Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 27. If you hit
a foreign object or ice jam, the snow thrower is
designed
so that the bolts will shear. This type of nut is
used where vibration occurs.
•
If the augers do not turn, check to see if the bolts
have sheared. Two replacement
shear bolts and
hex lock nuts have been provided with the snow
thrower. Since lock nuts cannot be threaded
onto a
bolt by hand, use a wrench. When replacing bolts,
spray an oil lubricant into shaft before inserting new
bolts.
•
To remove shave plate, remove carriage bolts,
belleville washers and hex nuts which attach shave
plate to the snow thrower housing. For location of
shave plate, see Figure 27.

of the carriage bolts are to the inside of the housing.
