Maintenance
•
Check the oil level daily. Refer to the engine opera-
tor's manual for the appropriate oil specification.
Verify that the oil is correct for special operating
conditions such as a change in season or climate.
• DO NOT start the unit if the engine oil level is
below the add mark on the dipstick.
• Normal operating level is in the cross-hatch
pattern between the full and add markings on
the dipstick.
Basic Maintenance Schedule
Refer to the diesel engine manufacturer's operating manual for a complete list of maintenance requirements. Failure to
comply with the procedures as described in the engine operator's manual will nullify the warranty, decrease perfor-
mance, and cause equipment damage or premature equipment failure. Maintenance records may be required to com-
plete a warranty request.
Use the schedule in the following tables as a guide for regular maintenance intervals. For additional or replacement
copies of the engine operator's manual, contact a GMP ASD.

† Generac Mobile Products, LLC recommends that oil change intervals on the MLT6SM equipped with the Mitsubishi L3E-W461ML Tier
4 engine be extended to 750 hours after initial break-in (if operating at high speed). The engine comes from the factory with a larger
sump that holds 5.5 quarts (5.2 L) of engine oil. After the initial 50 hour break-in and oil change, the sump, coupled with the larger oil
filter, allows the engine to operate up to 750 hours between routine oil changes.
Hot, humid, or dusty conditions can shorten engine oil service life, regardless of suggested oil change intervals. In extreme conditions,
determine oil life and change intervals through regular oil sampling and analysis.
Always follow the recommendations of the OEM engine manual that was shipped with the unit for specific operating instructions. If
further technical assistance is required, contact Generac Mobile Products Technical Service at 1-800-926-9768.
