Choose a location where the generator will not
be exposed to rain, snow or direct sunlight.
Common places for mounting your PTO generator
are to a trailer or a cement slab. However you
choose to mount the generator, make sure it can
get as close to the load as possible. This will make
using the generator more convenient and reduce
voltage drop.
The installation site must be free from water,
moisture, or dust. Foreign matters, such as dust, dirt,
sand, lint, or abrasive materials can cause damage

24 HP minimum.
if allowed inside the generator.
All electrical
components should be protected from excessive
moisture or the insulation system will deteriorate
and result in grounding or shorting out of the
generating system.
When trailer mounting the generator select a
trailer that is wide enough to withstand the torque
of start-up and loading torque. Wheels that are not
spaced properly could cause the trailer to tip over.
The constant vibration of the generator can cause
metal fatigue of the trailer base if the steel used is
not thick enough.
DANGER Always have proper guarding
of rotating parts.
Failure to guard the power
transmission mechanisms may result in serious
injury or death.
While seated on the tractor and the engine at
idle, engage the PTO. Slowly increase the throttle
until the needle in the generator voltmeter is at or
above the black line in the green area. A load can
now be applied to the generator. Remember to

When mounting the generator on a cement slab
use the optional mount kit (item #165935),
available in the Northern catalog and the NorthStar
parts catalog. The kit comes with two mounting
plates and three grade 5, 7/16-14 bolts. Use grade
5 3/8” anchor bolts to mount plates to the concrete.
If the control box is not located on the correct
side for your application, it can be rotated to the
opposite side. First remove the fan vents, then
remove the four drive end bracket bolts. Remove

STARTING ELECTRIC MOTORS
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.
LOAD APPLICATION
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
120V,

Starting Amps
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
contaminants. Over time the effectiveness of the
insulation is eliminated and a dead short can result.
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

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.

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.

GENERATOR CARE
GROUNDING - All units must be grounded.
Drive a 3/4” or 1” copper pipe or rod into the ground
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.

penetrate moist earth.
The pipe/rod must
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.
Exercising The Generator - The generator
should be operated every four weeks. 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.
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
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.

the clock should be correct within +/- 2 seconds per
minute. All speed setting adjustments should be
done by a qualified technician.
