Oil Check

Check the oil level in the crankcase every 24 hours of
operation or before the engine is started each day. Do
not check the oil level while operating the unit. Stop the
generator set and keep the generator set level to get an
accurate reading. To check the oil level, remove the
dipstick and wipe the end clean. Reinsert the dipstick
and wait at least 30 seconds. Remove the dipstick and
check the level. Maintain the oil level between the Full
and Add marks on the dipstick, as shown in Figure 4-2.
See Section 1, Service Views for the dipstick location.
Note: Do not operate the set if the oil level is below the
Add mark or above the Full mark on the dipstick.
