ENGINE BREAK-IN REQUIREMENTS
Note: During the first 20 hours of operation, avoid long periods of no load or sustained maximum load operation. If
the generator is to run for longer than five minutes without a load, shut the generator down.
The engine is supplied with engine break-in oil from the factory. Extra care during the first 100 hours of engine
operation will result in better performance and longer engine life.
DO NOT
exceed 100 hours of operation with the
break-in oil. Operate the engine at heavy loads (60-90% of maximum) as much as possible. If the engine has spent
significant time at idle, constant speeds and/or light load or if makeup oil is required, a longer break in period may
be needed. Consult the engine OPERATION AND MAINTENANCE MANUAL for a full description of necessary
procedures on the addition of break-in oil and extension of the break-in period. Use the schedule table on the following
page as a guide for regular maintenance intervals.
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
MAINTENANCE 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.
