Lubrication and Maintenance (Continued)
NOTE: Run Engine just prior to changing oil. Oil
will flow more freely and carry away more con­
tamination when warm.
Drain engine crankcase by removing oil drain
plug. After oil has drained replace plug.
Remove oil fill cap with dipstick and pouring
slowly, fill crankcase to full mark on dipstick
(approximately 2 pints) with oil. Check oil level
with dipstick being sure that you replace
dipstick and tighten cap firmly.
Air Cleaner
IMPORTANT: DO NOT run engine with air
cleaner removed. Operating engine with an ex­
tremely dirty air cleaner for only a brief period
of time can cause engine damage.
Inspect filter every twenty-five (25) operating
hours. (More often if unit is used under ex­
tremely dirty or dusty conditions.)
Remove the air filter cover by; loosening or
removing screws, or snapping tab open depen­
ding on which type of air cleaner is incor­
porated on your engine. Pull out the filter ele­
ment and wash thoroughly in warm water and
detergent. Rinse in clear water and squeeze
(DO NOT wring) dry. Wrap filter in clean cloth
and squeeze until dry. Saturate filter with
engine oil and squeeze to distribute and
remove excess oil. (DO NOT twist).
Clean inside of cover and body of filter holder.
Replace filter and cover and secure.
