Lubrication

For a view of the lubrication points on the snow thrower, see Figure 19.

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 accessed beneath the handle panel.

Gear Case

•The gear case is lubricated with grease at the factory and does not require checking. If disassembled for any reason, lubricate with two ounces of Shell Alvania grease.

Bearings

•Once a season lubricate the auger bearings and the bearings on the side of the frame with light oil. See lube chart below.

Check V-belts

Follow the instructions below to check the condition of the drive belts every 50 hours of operation.

•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 six 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 instructions and . Recheck the friction wheel.

•Replace friction wheel rubber if necessary. Refer to instructions on page 23.

Engine Maintenance

Engine Oil

Only use high quality detergent oil rated with API service classification SF, SG or SH. Select the oil’s SAE viscosity grade according to the expected operating temperature.

colder 32o warmer

5W30 SAE30

Viscosity Chart

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi- viscosity oils will result in increased oil consumption when used above 32oF. Check your snow thrower’s engine oil level more frequently to avoid possible engine damage from running low on oil.

Refer to the viscosity chart for proper selection of engine oil.

Checking Oil Level

Before operating the snow thrower, check the oil level.

•With engine on level ground, the oil must be to FULL mark on dipstick.

•Stop engine and wait several minutes before checking oil level. Remove oil fill cap and dipstick.
