DAILY MAINTENANCE CHECKS
Check the engine oil level daily before starting engine. DO NOT start the generator if the oil level is below
the ADD mark on the dipstick. The normal operating level for the engine oil is anywhere in the crosshatch pattern
between the FULL and ADD markings. Add oil to the engine only if the level is below the ADD mark on the bottom
of the crosshatch pattern. DO NOT OVERFILL the crankcase. Consult the engine OPERATION AND MAINTENANCE
MANUAL for the proper grade of oil, including special operating conditions such as a change in season or climate.
Check the coolant level daily. The coolant is checked by visually inspecting the level in the coolant overflow jug,
located near the radiator. The normal operating level is anywhere between the FULL and ADD markings on the
overflow jug, with the optimum level noted as “NORMAL RANGE”. Coolant may be added directly to the overflow jug
WHEN THE ENGINE IS STOPPED AND COMPLETELY COOL. Consult the engine OPERATION AND MAINTE-
NANCE MANUAL for coolant recommendations and proper mixture.
Check the condition of the air filter by viewing the level of vacuum draw on the filter minder gauge. Replace the air
filter when the yellow center bar reaches the red section on the gauge (20 in. H
2
0).
* Replace primary air cleaner when restriction indicator shows a vacuum of 25 in. H

** Change the oil and oil filter after the first 100 hours, then every 250 hours.
*** If engine manufacturer’s recommended coolant is used, the flushing interval may be extended. See engine
OPERATION AND MAINTENANCE MANUAL.
**** Check the torque of the generator drive plate bolts after the first 250 hours of operation, then annually.
