13Generator 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. 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.
• Use a soft bristle brush to loosen caked on dirt or
oil.
• Use a vacuum cleaner to pick up loose dirt and
debris.
Oil
Oil Recommendations
NOTE: When adding oil to the engine crankcase, use a
high quality detergent oil classified “For Service SF,
SG, SH, SJ” or higher. DO NOT use special additives.
1. Choose a viscosity according to the table below.
* Check oil level frequently at higher temperatures.
NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol with “SJ/CF
ENERGY CONSERVING” or higher, is an acceptable
oil at all temperatures. Use of synthetic oil does not
alter required oil change intervals.
When adjusting or making repairs to your
generator:
• Disconnect the spark plug wire from the spark plug and place
the wire where it cannot contact spark plug.
When testing for engine spark:
• Use approved spark plug tester.
• DO NOT check for spark with spark plug removed.
Unintentional sparking can result in fire or
electric shock.
WARNING
• DO NOT expose generator to excessive moisture, dust, dirt,
or corrosive vapors.
• DO NOT insert any objects through cooling slots.
Improper treatment of generator can damage it and
shorten its life.
