(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
these problems occur, call Customer Service at 1-800-
270-0810.
GROUNDING - All units must be grounded. Drive
a 3/4” or 1” copper pipe or rod into the ground close to
the generator. The pipe/rod must penetrate moist
earth. Connect an approved ground clamp to the pipe.
Run a 8 gauge wire from the clamp to the generator
ground screw. Do not connect to a water pipe or a
ground used by a radio system.
OPERATING SPEED
The generator must be run at the correct speed in
order to produce the proper electrical voltage and
frequency.
The output voltage should be checked to ensure
the generator is working properly subsequent to
connecting a load to the generator. Failure to do so
could result in damage to equipment plugged into the
unit and possible injury to the individual.
All engines have a tendency to slow down when a
load is applied. When the electrical load is connected
to the generator, the engine is more heavily loaded,
and as a result the speed drops slightly. This slight
decrease in speed, together with the voltage drop
within the generator itself, results in a slightly lower
voltage when the generator is loaded to its full capacity
than when it is running with no load. The slight
variation has no appreciable effect in the operation of
motors, lights and most appliances. Electronic
equipment and clocks will be effected if correct RPM is
not maintained. See Load vs. Output chart

Output voltage should be checked periodically to
ensure continued proper operation of the generating
plant and appliances, it can be checked with a portable
meter. Frequency can be checked by using an electric
clock with a sweep second hand. Timed against a
wrist watch or a stop watch the clock should be correct
within +/- 2 seconds per minute. All speed setting
adjustments should be done by a qualified technician.
