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
Personal Injury. Fuel lines are pressurized.
Servicing the fuel lines may release high
pressure fuel and could result in death or
serious injury.
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.
• 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.
