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 levef more frequently to avoid
possible engine damage from running low on oil.
Change the oil after the first two hours of operation and
every 25 hours thereafter or at least once a year if the lawn
mower is not 'bsed 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
