Daily Walk-Around Inspection

CAUTION
Equipment Damage. Failure to perform a daily
inspection could result in damage to the unit.
Perform a walk-around inspection of the unit every day
before starting the unit. Look for conditions that could
hinder performance or safety, such as (but not limited to):
•
Oil, coolant, and fuel leakage
•
Blocked vents
•
Loose or missing hardware

Loose or broken electrical connections
Inspect the fan belt for cracks, fraying, or stretching. Ver-
ify the belt is correctly seated in the pulley grooves.

General Maintenance

Poorly maintained equipment can become a safety
hazard. In order for the equipment to operate safely and
correctly over a long period of time, periodic maintenance
and occasional repairs are necessary. DO NOT perform
routine service (oil and filter changes, cleaning, etc.)
unless all electrical components are shut off.
Regular maintenance will improve performance and
extend engine/equipment life. Generac Mobile Products,
LLC recommends that all maintenance work be per-
formed by a GMP ASD. Regular maintenance, replace-
ment or repair of the 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, the work must be
performed by a GMP ASD or authorized Mitsubishi
engine dealer depending on the repair. See the emis-
sions warranty.

Always clean the unit after each use to remove dust,
grease, mud, or spilled fuel or oil. Use soft, clean rags to
wipe the cabinet exterior and control panel. Low-pressure
compressed air (less than 40 psi [276 kPa]) can also be
used to remove dust and debris from the cabinet interior.
This unit contains sensitive electronic components that
can be damaged by high pressure and heat. Do not:
•
wash the unit with a high pressure hose or power
washer.
•
wash the engine block or fuel tank with a power
washer or steam cleaner. Water may enter the
cabinet and collect in the generator windings or
other electrical parts, causing damage.

If the unit is stored outside, inspect for water inside
the cabinet and generator before each use. If wet,
dry the unit thoroughly before starting.
