Section 4 Maintenance and Troubleshooting

Maintenance Recommendations

Regular maintenance will improve perfor-
mance and extend generator life. See an
IASD for service.
Generator warranty does not cover items sub-
jected to operator abuse or negligence. To
receive full warranty value, operator must
maintain generator as instructed in this man-
ual, including proper storage as detailed in
Winter Storage and Long Term Storage.
NOTE: Call 1-888-GENERAC (1-888-436-
3722) with questions
replacement.

Maintenance Schedule

Preventive Maintenance

Dirt or debris can cause improper operation
and equipment damage. Clean generator
daily or before each use. Keep area around
and behind muffler free from combustible
debris. Inspect all cooling air openings on
generator.
WARNING
Do not insert any object through the air cooling slots.
Generator can start at any time and could result in
death, serious injury, and unit damage.
• Use a damp cloth to wipe exterior surfaces
clean.
• Use a soft bristle brush to loosen caked on
dirt, oil, etc.
• Use a vacuum to pick up loose dirt and
debris.
• Low pressure air (not to exceed 25 psi)
may be used to blow away dirt. Inspect
cooling air slots and openings on generator.
These openings must be kept clean and
unobstructed.
NOTE: DO NOT use a garden hose to clean
generator. Water can enter engine fuel system
and cause problems. If water enters generator
through cooling air slots, some water will be
retained in voids and crevices of rotor and sta-
tor winding insulation. Water and dirt buildup
on generator internal windings will decrease
insulation resistance of windings.

Engine Maintenance

Accidental start-up. Disconnect spark plug wires
when working on unit. Failure to do so could result
in death or serious injury.
Engine Oil Recommendations
Only high-quality detergent oils classified for
service SF, SG, SH, SJ or higher are recom-
mended. DO NOT use special additives.
Climate determines proper engine oil viscos-
ity. See chart to select correct viscosity.
