General Recommendations
Regular maintenance will improve the performance and
extend the life of the generator. See an 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 and the engine
operator’s manual.
• Some adjustments will need to be made periodically to
properly maintain your generator.
• All maintenance in this manual and the engine
operator’s manual should be made at least once each
season.
• Once a year you should clean or replace the spark plug,
clean or 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. Please refer to
your engine operator’s manual for more details.
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.
NOTE: 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. 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 can 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.
Fuel valve Maintenance
The fuel valve is equipped with a fuel sediment cup, screen,
retaining ring and o-ring that need to be cleaned every 100
hours or once a year (whichever occurs first).
1. Move fuel valve to “Off” position.
2. Remove sediment cup (A) from fuel valve. Remove
o-ring (b), retaining ring (c) and screen (D) from fuel
valve.
3. Wash sediment cup, o-ring, retaining ring, and screen
in a nonflammable solvent. Dry them thoroughly.
4. Place screen, retaining ring, and o-ring into fuel valve.
Install sediment cup and tighten securely.
5. Move fuel valve to “On” position, and check for leaks.
Replace o-ring if there is any leakage.
