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.
GENERATOR CARE
The generator head is a two pole, 3600 RPM,
60 Hz, brushless, revolving field and synchronous
type with two sealed radial bearings.
Proper care and maintenance are necessary to
ensure a long trouble free life.
Exercising The Generator - The generator
should be operated ev ery four w eeks. This is
accomplished by starting the engine and applying
a load for 15 minutes. This will dry out any
moisture that has accumulated in the windings. If
left, this moisture can cause corrosion in the
winding. Frequent operation of the generator will
also ensure that the set is operating properly should
it be needed in an emergency.
Generator Maintenance - The generator head
is brushless and maintenance free. Any major
generator service including the installation or
replacement of parts should be performed only by a
qualified electrical service technician. USE ONLY
NorthStar APPROVED REPAIR PARTS AVAILABLE
AT 1-800-270-0810.
A. Bearing - The bearings used in this generator
are a heavy duty, sealed ball bearing type. They
require no maintenance or lubrication.
B. Receptacles - Quality receptacles have been
utilized. If a receptacle should become cracked or
otherwise damaged, replace it. Using cracked or
damaged receptacles can be both dangerous to the
operator and destructive to the equipment.
WARNING, Stand-by Operation
If your generator is to be used as a standby
electric power source in case of utility failure, it
must be installed by a registered and licensed
electrician and in compliance with all applicable
state and local electrical codes. Also, local Fire
Departments must be consulted concerning proper
and safe handling procedures for gasoline. NEVER
connect any generator to any existing electrical
system without an isolating, UL approved transfer
switch, installed by a licensed electrician.
