Section 4 Maintenance and Troubleshooting

Maintenance

Regular maintenance will improve perfor-
mance and extend engine/equipment life. The
manufacturer recommends that all mainte-
nance work be performed by an Independent
Authorized Service Dealer (IASD). Regular
maintenance, replacement 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 an
IASD. See the emissions warranty.
NOTE: Call Powermate customer service at 1-
800-445-1805 with questions about compo-
nent replacement.

schedule intervals,

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.
