Return switch to OPERATION position
When the engine is not running, the oil
level gauge (dip stick) (figure 4-40) allows
the operator to check the oil level. The
gauge is stamped with an "H" (high, full)
and an "L" (low) level mark to indicate
lubricating oil supply. The crankcase
should be filled to the "H" mark on the
Never fill crankcase above "H" mark
When the engine is running, check the oil
level using the sight gauge. Set sight
gauge high level marker (2, figure 4-43)
while engine is not running and dipstick
shows oil at "H" (full). Set sight gauge low
level marker (4, figure 4-43) to indicate oil
level while engine is running. The sight
gauge will then show both operating and
nonoperating levels. Recheck oil level on
dipstick after setting sight gauge markers
to ensure that no oil was leaking during
the setting of the markers. After setting
sight gauge level markers, use the sight
gauge rather than the dipstick to monitor
Keep oil free of water and abrasives by
proper handling and storage.
Inspect engine for evidence of oil leaks.
After each operating interval of 300 hours,
remove breather and clean with cleaning
solvent, blow out with compressed air,
and reinstall on engine. See figure 4-8A.
Lubricating Instructions. Oil shall be changed
every 300 hours or 3 months, whichever comes
first. Oil may require changing more frequently
than usual because contamination by dilution
and sludge formation will increase under cold
weather operation conditions.
Before draining the oil system, operate
