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 16.
Check Friction Wheel
Follow instructions below to check the condition of the
friction wheel rubber every 50 hours of operation.
1. Remove the self-tapping screws from the frame
cover underneath the snow thrower. Refer to
Figure 15.
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 (refer
to page 19) and recheck the friction wheel.
4. Replace friction wheel rubber if necessary. Refer to
instructions on page 18.
5. Re-attach frame cover to the snow thrower and put
the equipment back to operating position.
Checking Oil Level
Lubricate
shift rod &
Before operating snow thrower, check the oil level by
shift arm
following steps below.
NOTE: Although multi-viscosity oils (5W30, 10W30
etc.) improve starting in cold weather, these multi-
viscosity oils also result in higher oil consumption when
used above 32
level more frequently to avoid possible engine damage
from running low on oil.
1. With engine on level ground, oil must be to FULL
mark on dipstick. See Figure 10 .
2. Stop engine and wait several minutes before
checking oil level. Remove oil fill cap and dipstick.
3. Wipe dipstick clean, insert it into oil fill hole and
tighten securely.
4. Remove dipstick and check. If oil is not up to the
FULL mark on dipstick, add oil.
