Check V-Belts
Follow instructions below to check the condition of the
drive belts every 50 hours of operation.
1.
Remove the plastic belt cover on the front of the
engine by removing two self-tapping screws.
2.
Visually inspect for frayed, cracked, or excessively
worn out belts. Replace, if necessary, following
instructions on page 14.
Check Friction Wheel
Follow instructions below to check the condition of the
friction wheel rubber every 50 hours of operation.
1.
Remove two self-tapping screws from the frame
cover underneath the snow thrower. Refer to
Figure 18.
2.
Visually inspect the friction wheel rubber for
excessive wear, cracks, or loose fit on the friction
wheel drive hub.
3.
Also engage the drive control and check if the
friction wheel is making contact with drive plate. If it
does not make contact, adjust the drive cable and
recheck the friction wheel.
4.
Replace friction wheel rubber if necessary. Refer to
instructions on page 15.
5.
Re-attach frame cover to the snow thrower and put
the equipment back to operating position.
Check Chute Cables
Once a season or every 25 hours of operation,
whichever is earlier, check whether the chute cables
have slackened. Adjust if necessary, following
instructions on page 17.
SECTION 5: SERVICE & ADJUSTMENT
•
All adjustments in the Service and Adjustments
section of this manual should be checked at least
once each season.
Servicing Augers
The augers are secured to the spiral shaft with two
shear pins and cotter pins. See Figure 15 . If you hit a
foreign object or ice jam, the snow thrower is designed
so that the bolts will shear.
1.
If the augers do not turn, check to see if the pins
have sheared.
2.
Replace the pins if needed. Two replacement shear
pins and cotter pins have been provided with the
snow thrower. Spray an oil lubricant into shaft
before inserting new pins and securing with new
cotter pins. See Figure 15.
