nent replacement.
Maintenance Schedule
Follow maintenance schedule intervals, whichever
occurs first according to use.
NOTE: Adverse conditions will require more frequent ser-
vice.

completed as detailed in the following chart.
Preventive Maintenance
WARNING: Personal injury. 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. (000142a)
Dirt or debris can cause incorrect operation and equip-
ment damage. Clean generator daily or before each use.
Keep area around and behind muffler free from combus-
tible debris. Inspect all cooling air openings on genera-
tor.
• 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 stator wind-
ing insulation. Water and dirt buildup on generator inter-
nal windings will decrease insulation resistance of
windings.
Engine Maintenance
