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).
Auger Gear Box - The auger gear box has been
factory lubricated for life. If for some reason lubricant
should leak out, have the auger gear case checked by
a competent repairman.
ENGINE
LUBRICATION
Check the crankcase oil level (See FIG. 4) before starting
the engine and after each five (5) hou rs of continuous use.
Add S.A.E. 5W-30 motor oil as needed. Tighten fill cap/
dipstick securely each time you check the oil level.
OIL RECOMMENDATION
Only use high quality detergent oil rated with API service
classification SG. Select the oil's viscosity grade accord-
ing to your expected operating temperature:
RECOMMENDED VISCOSITY GRADES
COLDER_<-- i2 ° --_>WARMER
5W30 SAE30
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.

SPARK PLUG
• Make sure that the spark plug is tightened securely
into the engine and the spark plug wire is attached to
the spark plug.
• If a torque wrench is available, torque plug to 18 to 23
foot pounds.
• Clean the area around the spark plug base before
removal to prevent dirt from entering the engine
• Clean the spark plug and reset the gap periodically to
.030 inch (See FIG. 6).
