CHANGE OIL
Change oil after the first 8 hours of

operating conditions, change oil every
50 hours of operation or monthly,
whichever occurs first.
NOTE: Oil should be changed
every 25 hours of operation if
the engine is operated under
heavy load, or in high ambient
temperatures.
When changing oil use a high quality
SAE 10W-30 or SAE 30 weight detergent
oil classified “For Service SC, SD, SE, SF or
SG”. Detergent oils keep the engine
cleaner and retard the formation of
gum and varnish deposits. No special
additives should be used with
recommended oils. The following table
provides the recommended viscosities
of oil to use based on the anticipated
operating temperature range.
