MAINTENANCE

WARNING: Disconnect the spark

the engine before performing
any repairs or maintenance
AUGERS
The augers are secured to the spiral shaft
with two shear bolts and hex locknuts.
See Figure 23. If you hit a foreign object
or ice jam, the snowthrower 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 replace-
ment hex bolts and hex lock nuts have
been provided with the snowthrower.
When replacing bolts, spray an oil lubri-
cant into shaft before inserting new bolts.
SHAVE PLATE AND SLIDE SHOES
The shave plate and slide shoes on the
bottom of the snowthrower are subject to
wear. They should be checked periodi-
cally and replaced when necessary.
NOTE: Some models are equipped
with reversible slide shoes and
may be turned over to increase
their lifespan.
