Always compare the generator nameplate data
with that of the equipment to be used to ensure that
watts, volts, amperage, and frequency requirements
are suitable for operating equipment. The wattage
listed on the equipment nameplate is its rated output.
However, some equipment may require three to ten
times more wattage than its rating on the nameplate,
as the wattage is influenced by the equipment
efficiency, power factor and starting system. NOTE: If
wattage is not given on equipment nameplate,
approximate wattage may be determined by

STARTING ELECTRIC MOTORS
DANGER Remember, exhaust fumes are
Electric motors require much more current (amps)
to start than to run. Some motors, particularly low cost
split-phase motors, are very hard to start and require 5
to 7 times more current to start than to run. Capacitor
motors are easier to start and usually require 2 to 4
times as much current to start than to run. Repulsion
Induction motors are the easiest to start and require
1.5 to 2.5 times as much to start than to run.
Most fractional motors take about the same
amount of current to run them whether they are of
Repulsion-Induction (RI), Capacitor (Cap), or Split-
Phase (SP) type. The following chart shows the
approximate current required to start and run various
types and sizes of 120 volt 60 cycle electric motors
under various conditions.

It is important to determine the total electrical load
before it is connected to the generator. The two major
factors in determining the life of a generator head are:
heat build up, caused by overloading the generator
and corrosive contaminants, that attack the wiring
insulation. If the generator is overloaded, the wires
become excessively hot and cause the insulation to
break down, reducing its ability to resist corrosive

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.

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.

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 10 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.
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.
OPERATING SPEED
The generator must be run at the correct speed in
order to produce the proper electrical voltage and
frequency.
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.
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
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.

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 roller bearings.
Proper care and maintenance are necessary to
ensure a long trouble free life.
Exercising The Generator - The generator
should be operated every four weeks.. This is
accomplished by starting the engine and applying a
load for 10 to 15 minutes. This will dry out any
moisture that has accumulated in the windings. If left,
