Drive/Auger Control Lock: The cam on the ends
of the control rods which interlock the drive and
auger controls must be lubricated at least once a
season or every 25 hours of operation using a
multi-purpose automotive grease. The cam can be
accessed beneath the handle panel. See Figure 15

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 17.
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 21.
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 21) and recheck the friction wheel.
4. Replace friction wheel rubber if necessary. Refer to
instructions on page 19.
5. Re-attach frame cover to the snow thrower and put
the equipment back to operating position.
Checking Oil Level
Before operating snow thrower, check the oil level by
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°F. Check your snow thrower's engine oil
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 16.
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.

Changing Oil
Change engine oil after first two hours of operation and
every 25 hours thereafter.
In order to change oil, you will have to first drain the
used engine oil from the engine and then refill with fresh
oil.
1. Drain oil while engine is warm. Remove oil drain
plug located at the bottom of the recoil starter of the
engine. Catch oil in a suitable container.
2. When engine is drained of all oil, replace drain plug
securely.
3. Remove the dipstick from the oil fill. For location of
the oil fill, see Figure 13. Pour fresh oil slowly
through the plug. Replace dipstick.
Check and make sure that the level of oil is up to the
FULL mark on the dipstick.
