Craftsman 536.88123 operating instructions Oil Recommendation, Engine Lubrication

LUBRICATION

• Hex Shaft and Gears - Hex shaft and

gears require no lubrication. All bearings and bushings are lifetime lubricated and require no maintenance.

NOTE: Any greasing or oiling of the above components can cause contamination of the friction wheel. If the disc drive plate or friction wheel comes in contact with grease

or oil, damage to the friction wheel will re- sult.

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 motor oil to prevent rusting. See second figure on page 15.

•Auger Gear Box - The auger gear box is lubricated at the factory and should not

require additional lubrication. If for some reason the lubricant should leak out, or if

the auger gear box has been serviced,

add Lubriplate No. 630-AA or equivalent.

Maximum 3-1/4 ounces should be used.

Remove filler plug as seen in figure below once a year. If grease is visible, do not add. If grease is not visible, use a piece of fine wire like a dipstick, to check if there is grease in the gearbox. Add grease if necessary. Reinstall gear box filler.

OIL RECOMMENDATION

Only use high quality detergent oit rated with AP_ service classification SG. Select

the oil'sviscosity grade according to your expected operating temperature:

NOTE: For extreme cold operating condi- tions of 0° and below, use a partial synthetic 0W30 motor oil for easier starting.

Change the oil every twenty-five (25) hours thereafter, and at the beginning of each season.

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

•Replace the oil drain plug and tighten se- curely.

SPARK PLUG

Make sure that the spark plug is tight- ened 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 at .030 inch.

LUBRICATION

Check the crankcase oil level (see figure be-

low) before starting the engine and after each five (5) hours of continuous use. Add

S.A.E. 5W30 motor oil as needed. Tighten

fill cap/dipstick securely each time you check the oil level.
