Owner’s Manual for Mobile Light Tower 37
Maintenance
* Replace the air cleaner element yearly, or after six cleanings, whichever occurs first.
** Generac Mobile recommends that oil change intervals on the MLT6SKDS equipped with the Kubota engine be
extended to 750 hours after initial break-in. The engine comes from the factory with a larger sump that holds 5.5
qts (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. 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 Technical Service at 1-800-926-9768.
