Power Management
To prolong the life of your generatorand attacheddevices, it
is important to take carewhen adding electrical loadsto your
generator. Thereshould be nothing connectedto the
generator outlets before starting its engine.Thecorrect and
safe way to managegeneratorpower isto sequentiallyadd
loads asfollows:
1. With nothing connectedto the generator,start the
engine asdescribed in this manual.
2. Plug in andturn on the first load, preferablythe largest
load you have.
3. Permit the generatoroutput to stabilize (engine runs
smoothly and attacheddeviceoperates properly).
4. Plug in andturn on the next load.
5. Again, permit the generatorto stabilize.
6. Repeatsteps 4 and 5 for eachadditional load.

or any other foreign material.
NOTICE DONOTusewater or other liquids to clean
generator. Liquids canenter 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 retainedin voids and cracks of the rotor and
stator winding insulation. Liquid and dirt buildup on the
generator internalwindings will eventuallydecreasethe
insulation resistanceof these windings.
Cleaning
Dailyor before use, look around and underneaththe
generatorfor signs of oil or fuel leaks. Cleanaccumulated
debris from inside and outside the generator. Keepthe
linkage, spring and other engine controls clean. Keepthe
areaaround and behind the muffler free from any
combustible debris. Inspect cooling air slots and openings
on generator. Theseopenings must be kept cleanand
unobstructed.
Engine parts should be kept cleanto reducethe risk of
overheating and ignition of accumulateddebris:
• Use a damp cloth to wipe exterior surfaces clean.
NOTICE Improper treatment of generator can damage it
and shorten its life.
• DO NOTexposegenerator to excessivemoisture, dust, dirt, or
corrosive vapors.
• DONOTinsert any objects through cooling slots.
• Use a soft bristle brush to loosen cakedon dirt or oil.
• Use a vacuum cleanerto pick up loose dirt and debris.
