Section 4 Maintenance and Troubleshooting
Maintenance Recommendations
Regular maintenance will improve perfor-
mance and extend generator life. See a quali-
fied dealer 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.

Every 100 Hours or Every Season*
Change oil ǂ
Every Season
Replace spark plug
Check valve clearance***
Every 200 Hours or Every Season
Inspect/clean air filter**
ǂ Change oil after first 30 hours of operation,
then every season.
* Change oil and oil filter every month when
operating under heavy load or in high tem-
peratures.

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.
