General Maintenance
WARNING
Accidental start-up. Disconnect negative battery
terminal before servicing to prevent accidental engine
rotation. Failure to do so could result in death or
serious injury.
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.
IMPORTANT NOTE: DO NOT perform routine service
(oil and filter changes, cleaning, etc.) unless all elec-
trical components are shut off.
Regular maintenance will improve performance and
extend engine/equipment life. Generac Mobile Products,
LLC recommends that all maintenance work be
performed by a GMP ASD. Regular maintenance,
replacement, or repair of emissions control devices and
systems may be performed by any repair shop or person
of the owner's choosing. However, to obtain emissions
control warranty service free of charge, work must be
performed by a GMP ASD or authorized Mitsubishi
engine dealer depending on the repair. See the
emissions warranty.
