TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)

improve starting in cold weather, these multi-viscosity oils

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 operation orat least

once ayear 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.

tank by running engine until fuel tank is empty.

wire where it cannot come in contact with spark plug.

» Be sure lawn mower is on level surface.
