The figures given above are for an average load
such as a blower or fan. If the electric motor is
connected to a hard starting load such as an air
compressor, it will require more starting current. If it is
connected to a light load or no load such as a power
saw, it will require less starting current. The exact
requirement will also vary with the brand or design of
the motor.
Generators respond to severe overloading
differently than the power line. When overloaded, the
engine is not able to supply enough power to bring the
electric motor up to operating speed. The generator
responds to the high initial starting current, but the
engine speed drops sharply. The overload may stall
the engine. If allowed to operate at very low speeds,
the electric motor starting winding will burn out in a
short time. The generator head winding might also be
damaged.
Running the generator under these conditions may
result in damage to the generator stator as well as the
electric motor windings. Because the heavy surge of
current is required for only an instant, the generator
will not be damaged if it can bring the motor up to
speed in a few seconds. If difficulties in starting a
motor are experienced, turn off all other electrical
loads and if possible reduce the load on the electric
motor.
EXTENSION CORDS
When electric power is to be provided to various
loads at some distance from the generator, extension
cords can be used. These cords should be sized to
allow for distance in length and amperage so that the
voltage drop between the set and point of use is held
to a minimum.

(a) Hard-starting motors require 3 to 5 times the
rated running watts.
(b) These loads may require up to 15 minutes to
restart due to its normal build up of compressor head
pressure.
NOTE: For extremely hard to start loads such as
air conditioners and air compressors, consult the
equipment dealer to determine the maximum wattage.
PRE-START UP PREPARATIONS
Your generator has been thoroughly tested prior to
shipment from the factory. However, damage can
occur during shipping, so be sure to check for
damaged parts, loose or missing nuts and bolts. If the
aforementioned problems occur, call customer service
at 1-800-270-0810.
