WARNING:
Always stop engine, disconnect
spark plug wire and move it away from the
spark plug before performing any adjustments
or repairs on the snow thrower.
WARNING:
Never attempt to clean the
discharge chute or make any adjustments
while the engine is running.
Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If snow thrower hits a
hard foreign object or ice jam, the bolts may shear.
Refer to Figure 15. If the augers will not turn, check to
see if the bolts have sheared.
Use replacement shear bolts and lock nuts provided
with the snow thrower. When replacing bolts, spray an
oil lubricant into shaft before inserting new bolts.
IMPORTANT:
Never replace auger shear bolts with
standard hex bolts. Any damage to the auger gearbox
or other components from hex bolt usage will not be
covered by the snow thrower's warranty.
Shave Plate and Skid Shoes
1.
The shave plate and skid shoes on the bottom of
the snow thrower are subject to wear. Check
periodically and replace when necessary.
2.
Remove the four carriage bolts and hex nuts which
attach two skid shoes to the snow thrower on two
sides. See Figure 16.
