Keep generator
clean
Keep generator clean.
If dust or debris accumulates on the generator, clean the generator with a
damp cloth or soft bristle brush. Do not allow air intakes to become blocked.
Note: Do not spray generator with a garden hose or pressure washer.
Water may enter the generator and cause damage to the rotor, stator, or
internal windings.
Recharge and
maintain battery
(if electric start)
Inspect, recharge, and maintain your battery according to your battery
manufacturer’s instructions. (Only for those models equipped with electric
start.)
Do not store with battery charger always connected. Batteries that are over-
charged can boil themselves dry and produce excessive amounts of hydrogen,
an explosive gas.
Brush Assembly
Maintenance
Inspect brushes every 12 months, or 200 hours.
Replace brush assembly after 1000 hours of operation.
Hours of operation and environmental conditions influence
brush life.
Look for excessive or uneven wear, if either condition is
present, take the unit to a qualified repair technician.
IMPORTANT:
If a part needs replacement, only use parts that meet the manufacturer’s specifications. Replace-
ment parts that do not meet specifications may result in a safety hazard or poor operation of the
generator.
