ENGINE

LU BRICATION

Use only high quality detergent oil rated with API service classification SG-SL. Select the

oil's SAE viscosity grade according to your expected operating temperature.

SAE VISCOSITY GRADES

-20		0	30	32	40	60	80	100
-30	-20	-10		0		10	20	30	40
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, they will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil. Change the oil after every 25 hours of opera- tion orat least once a year if the lawn mower

is not used for 25 hours in one year. Check the crankcase oil level before

starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.

TO CHANGE ENGINE OIL

1.Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

2.Be sure lawn mower is on level surface.

NOTE: Oil will drain more freely when warm. Catch oil in a suitable container.

3.Remove bottom oil drain plug.

4.After oil has drained completely, replace oil drain plug and tighten securely.

5.Fill engine with oil. (See "ADD OIL" in the Operation section of this manual).

6.Reconnect spark plug wire to plug.
