(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 their 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 PREPARATIONS
Your generator has been thoroughly tested prior to
shipment from the factory. A factory test report has
been included with this manual. However, damage
can occur during shipping, so be sure to check for
damaged parts or loose or missing nuts and bolts. If
the aforementioned 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 no. 12 Ga. wire from the clamp to the generator
grounding screw located on the generator head. Do
not connect to a water pipe or a ground used by a
radio system.
CAUTION:
The engine has been shipped without
oil. Fill the crankcase with oil before trying to start.
Low oil shut-down prevents your generator from
starting without sufficient oil.
OPERATING SPEED
The generator must be run at the correct speed in
order to produce the proper electrical voltage and
frequency. The speed of the engine was carefully
adjusted at the factory so that the generator produces
the proper voltage and frequency.
The output voltage should be checked with a
voltmeter to ensure the generator is working properly
before 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 affected if correct RPM is
not maintained. See Load vs. Output chart.
