Maintenance
Maintenance Schedule
Follow the hourly or calendar intervals, whichever occurs first. More frequent
service is required when operating in adverse conditions noted below.
¹
Service more often under dirty or dusty conditions.
General Recommendations
Regular maintenance will improve the performance and extend the life of the
generator.
See any authorized dealer for service.
The generator’s warranty does not cover items that have been subjected to
operator abuse or negligence. To receive full value from the warranty, the
operator must maintain the generator as instructed in this manual.
NOTICE
Improper treatment of generator could damage it and shorten its
life.
• NEVER operate generator without protective housing or covers to assure
proper cooling.
Some adjustments will need to be made periodically to properly maintain your
generator.
All service and adjustments should be made at least once each season.
Follow the requirements in the Maintenance Schedule chart above.
NOTICE
Once a year you should clean or replace the spark plug and replace
the air filter. A new spark plug and clean air filter assure proper fuel-air mixture
and help your engine run better and last longer.
Generator Maintenance
Generator maintenance consists of keeping the unit clean and dry. Operate
and store the unit in a clean dry environment where it will not be exposed to
excessive dust, dirt, moisture, or any corrosive vapors. Cooling air slots in the
generator must not become clogged with snow, leaves, or any other foreign
material.
NOTICE
DO NOT use water or other liquids to clean generator. Liquids can
enter engine fuel system, causing poor performance and/or failure to occur. In
addition, if liquid enters generator through cooling air slots, some of the liquid
will be retained in voids and cracks of the rotor and stator winding insulation.
Liquid and dirt buildup on the generator internal windings will eventually
decrease the insulation resistance of these windings.
Cleaning
Daily or before use, look around and underneath the generator for signs of oil or
fuel leaks. Clean accumulated debris from inside and outside the generator. Keep
the linkage, spring and other engine controls clean. Keep the area around and
behind the muffler free from any combustible debris. Inspect cooling air slots and
openings on generator. These openings must be kept clean and unobstructed.
Engine parts should be kept clean to reduce the risk of overheating and
ignition of accumulated debris:
• Use a damp cloth to wipe exterior surfaces clean.
NOTICE
Improper treatment of generator could damage it and shorten its
life.
• DO NOT expose generator to excessive moisture, dust, dirt, or corrosive
vapors.
• DO NOT insert any objects through cooling slots.
• Use a soft bristle brush to loosen caked on dirt or oil.
• Use a vacuum cleaner to pick up loose dirt and debris.
Battery Maintenance (Model 030620 only)
Other than float charging, described elsewhere, no maintenance is required for
the starting battery. Keep the battery and terminals clean and dry.
NOTICE
Battery charging should be performed in a dry location, such as
inside a garage.
Fuel Valve Maintenance
Figure

The fuel valve is equipped with a fuel sediment cup, screen, and o-ring that
need to be cleaned.
1. Move fuel valve to off (
0
) position.
2. Remove sediment cup (
A
) from fuel valve. Remove o-ring (
B
) and
screen (
C
) from fuel valve.
3. Wash sediment cup, o-ring, and screen in a nonflammable solvent. Dry
them thoroughly.
4. Place screen and o-ring into fuel valve. Install sediment cup and tighten
securely.
5. Move fuel valve to on (
I
) position, and check for leaks. Replace fuel
valve if there is any leakage.
