FILTERS
A planned program of regular filter cleaning or
replacement will pay dividends in improved engine
life operation and reliability.
Air Filter Service air cleaner and replace element in
accordance with instructions in the engine manufac-
turer's manual. Perform this operation at times
specified in the operator maintenance schedule.
Air Restriction Indicator (Spec A-F): Located on the
duct between air filter and turbocharger to signal
condition of the air filter. When the RED signal
indicator on the device is fully exposed it is locked in
position.
At this time the air filter should be serviced.
After servicing air filter, reset indicator by depressing
the reset button on top of the unit.
Sets beginning Spec G do not have air restriction Indicator.

Oil Filters: Replacement of crankcase lubricating oil
and filters is recommended every 100 operating
hours,
or, on standby generator sets, every three
months. These time periods are for ideal situations
and must be adjusted lower if conditions warrant.
Replace filters at every oil change.
Fuel Filter Replace fuel filter every 3 months or more
often under extremely dusty conditions if used on a
standby unit; 200-250 operational hours in
con-
tinuous service.
