ENGINE MAINTENANCE
Note: During the first 50 hours of operation, avoid long periods of no load or sustained maximum load operation. If
the light tower is to run for longer than five minutes without a load, shut the engine down.
The engine is supplied with engine break-in oil from the factory. Extra care during the first 50 hours of engine
operation will result in better performance and longer engine life. DO NOT exceed 50 hours of operation with the
break-in oil. Operate the engine at lighter loads (50-75% 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 proce-
dures on the addition of break-in oil and extension of the break-in period.
The periodic maintenance schedule below lists basic maintenance intervals for the engine. For detailed mainte-
nance procedures refer to the engine operators manual
.
A copy of this manual was supplied with the unit when it
was shipped from the factory. For additional or replacement copies of the engine operators manual, contact an
authorized engine dealer in your area.

Drain the fuel filter daily in rainy or humid conditions.

Change the engine oil and filter after the first 50 hours of operation, then every 250 hours.
*** Replace the optional heated fuel filter every 1,000 hours (on MLT5200).
