Poorly maintained equipment can become a safety
hazard. In order for the equipment to operate safely and
properly over a long period of time, periodic maintenance
and occasional repairs are necessary. DO NOT perform
routine service unless all electrical components are OFF.
Regular maintenance will improve performance and
extend engine/equipment life. Generac Mobile Products
LLC recommends all maintenance work be performed by
a Generac Mobile Products Authorized Dealer (ASD).
Inspecting the Unit
•
If the unit is stored outside, check for water inside
the cabinet and control panel cover before each
