recommended oils.
CHANGE ENGINE OIL
Change engine oil after the first 8 hours of operation.
Thereafter, change oil every 50 operating hours.
Change oii more frequentiy if operating consistently
under heavy load or at high ambient temperatures.
• Warm up engine for at least five minutes, then shut down.
• With engine still warm from running, clean area around
oil drain plug and remove oil drain plug (Figure 4). Drain
oil completely into a suitable container.
• When oil has drained, install and tighten drain plug.
• Remove oil dipstick and fill crankcase with the recom­
mended oil (See Page 8). The engine crankcase can hold
about 1 quart (950ml). DO NOT FILL ABOVE “FULL”
MARK.

Replace the engine oil filter after the first 8 hours of
operation, every 50 operating hours thereafter.
• Turn oil filter counterclockwise to remove (Figure 4).

• Turn new filter clockwise until its gasket contacts lightly
with the filter adapter. Then tighten with an additional 3/4
to one turn by hand.
• Run engine and check for leaks.
NOTE: Check oil level and fill to full mark after
checking for leaks. Filter will retain some oil.
