Lubrication
For a view of the lubrication points on the snow
thrower, see Figure 20.
Sprocket Shaft
Lubricate the sprocket shaft with grease at least
once a season or after every 25 hours of
operation.
IMPORTANT: Keep all grease and oil off of the
friction wheel and the drive plate.
Shifting Mechanism
Lubricate the shifting mechanism and pivot
points on the shift rod with engine oil at least
once a season or after every 25 hours of
operation.
Traction Drive Control
• Lubricate cams on the ends of the control rods
which interlock the traction drive and auger
controls at least once a season or every 25
hours of operation with grease. The cams can be

• Remove the plastic belt cover on the front of the
engine by removing two self-tapping screws.
Visually inspect for frayed, cracked, or
excessively worn out belts.
Check Friction Wheel
Follow the instructions below to check the condition of
the friction wheel rubber every 25 hours of operation.
Remove the four self-tapping screws from the
frame cover underneath the snow thrower.
• Visually inspect the friction wheel rubber for
excessive wear, cracks, or loose fit on the
friction wheel drive hub.
• Also engage traction drive control and check if
the friction wheel is making contact with the
friction plate.
• If it does not make contact, adjust the traction
drive cable following adjustment instructions.
Recheck the friction wheel.
• Replace friction wheel rubber if necessary.
Refer to instructions on page 22.
