4.3.2 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 o il level between the F ull
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.

4.3.3 Oil Additions
Adding some oil between oil changes is normal. The
amount varies with generator set usage. Open the oil fill
cap and pour in a small amount of oil using a funnel or
other suitable pouring device. See Section 1, Service
Views, for the oil check and oil fill locations.
4.3.4 Oil and Filter Change
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Press the generator set off/reset
button to shut down the generator set. (2) Disconnect the
power to the battery charger, if equipped. (3) Remove the
battery cables, negative (--) lead first. Reconnect the negative
(--) lead last when reconnecting the battery. Follow these
precautions to prevent the starting of the generator set by the
remote start/stop switch.
Change the oil after the first 40 hours of engine
operation. Then change the oil according to the service
schedule or before generator set storage. Change the
oil more frequently if the generator set operates under
dirty, dusty conditions. Change the oil while the engine
is still warm. See Section 1, Service Views, for oil fill, oil
check, and oil filter locations.
Dispose of all waste materials (engine oil, fuel, filter,
etc.) in an environmentally safe manner.
