CUSTOMER RESPONSIBILITIES

LUBRICATION

Hex Shaft and Gears - Hex shait and gears require no lubrication. All bearings and bushings =t? lifetime lubricated and require no maintenance (See FIG. 3).

NOTE: Any greasing or oiling of the above components can cause contamination of the friction wheel. If the disc

drive plate or friction wheel come in contact with grease or oil, damage to the fdction wheel will result.

Should grease or oil come in contact with the disc drive plate or friction wheel, be sure to clean the plate and wheel

thoroughly.

NOTE: For storage, the hex shaft and gears should be

wiped with 5W-30 motoroil to prevent rusting(See FIG. 3).

5W30SAE30

NOTE: For extreme cold operating conditions of 0° F. and below, use a partial synethetic 5W30 motor oil for easier starting.

NOTE: Although multi-viscosity oils improve starting in cold weather, these multi-viscosity oils will result in in- creased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.

Position snow thrower so that the oil drain plug is lowest point on the engine. Remove oil drain plug and oil fill cap/dipstick. Drain oil into a suitable container Oil will drain more freely when warm.

Replace oil drain plug and tighten securely. Refill crankcase with S.AE. 5W-30 motor oil.
