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 inthis 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.

NEVERadd more loads than the generatorcapacity.Take

special careto consider surge loads in generator capacity,as

described above.

generator. Liquids canenter engine fuel system, causing

poor performance and/or failure to occur. In addition, if

liquid enters generator through cooling air slots, someof the

liquid will be retainedin voids and cracksof 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 andopenings

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.
