EXTENSION CORD CABLE SIZE
Refer to the table below to ensure the cable size of the extension cords you use are capable of carrying the required load.
Inadequate size cables can cause a voltage drop, which can burn out the appliance and overheat the cord.

ELECTRIC MOTOR LOADS
It is characteristic of common electric motors in normal operation to draw up to six times their running current while starting.
This table may be used to estimate the watts required to start electric motors; however, if an electric motor fails to start or
reach running speed, turn off the appliance or tool immediately to avoid equipment damage. Always check the requirements
of the tool or appliance being used compared to the rated output of the generator.

NOTICE:
Operating voltage and frequency requirement of all
electronic equipment should be checked prior to plugging
them into this generator. Damage may result if the
equipment is not designed to operate within a +/- 10%
voltage variation, and +/- 3 hz frequency variation from the
generator name plate ratings. To avoid damage, always
have an additional load plugged into the generator if
solid state equipment (such as a television set) is used.
A power line conditioner is recommended for some solid
state applications.
ELECTRICAL
GROUND FAULT CIRCUIT INTERRUPTER
See Figure 1.
The 20 amp, 120 volt receptacles on the generator are
protected by a Ground Fault Circuit Interrupter (GFCI),
which guards against the hazards of ground fault currents.
An example of ground fault current is the current that would
flow through a person who is using an appliance with faulty
insulation and, at the same time, is in contact with an electrical
ground such as a plumbing fixture, wet floor, or earth.
GFCI receptacles do not protect against short circuits,
overloads, or shocks.
The GFCI receptacles can be tested with the TEST and
RESET buttons.
To test:

Depress the TEST button. This should cause the Reset
button to pop out.
 To restore power, depress the RESET button.
Perform this test monthly to ensure proper operation of the
GFCI. If the generator is stored outdoors, unprotected from
the weather, test the GFCI receptacle before each use.
