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.
