generator so that the exhaust fumes will not be
directed towards people.
NEVER operate the generator, or handle any
electrical equipment while standing in water, while
barefoot, while hands are wet or while in the rain or
snow. Electric shock may result.
The installation site must be free from water,
moisture, or dust. All electrical components should be
protected from excessive moisture or the insulation
system will deteriorate and result in grounding or
shorting out the generating system.
Foreign matters, such as dust, dirt, sand, lint, or
abrasive materials can cause damage to the generator
head and engine if allowed into its cooling system.
ALWAYS use a ground fault circuit interrupter
(GFCI) in damp or highly electrical conductive areas
and on construction job-sites to prevent electric shock.
ALWAYS remove the spark plug or spark plug
wire before working on the engine or generator, to
prevent accidental starting.
NEVER install your generator inside confined
areas. Inside installation can cause health hazards or
death.
ALWAYS provide adequate ventilation. Do not
operate generator in any enclosed or narrow space.
Engines consume oxygen and give off deadly carbon
monoxide poisonous gas. Improper ventilation will
cause damage to generator and possible injury to
people.
DANGER Remember, exhaust fumes are
deadly carbon monoxide gas, and must be vented to
the outside where there are no people. Cooling air of
sufficient amounts must be allowed to flow in and
exhausted out to ensure proper cooling of the engine
and generator head.
NEVER touch hot muffler, hot exhaust manifold or
engine cooling fins.
LOAD APPLICATION
ALWAYS remove all oil or gasoline deposits and
accumulated dirt from generator and immediate area.
Keep generator head and engine clean.
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 can 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 system. NOTE: If
wattage is not given on equipment nameplate,
approximate wattage may be determined by
NEVER operate the generator under the following
conditions:
A. Excessive change in engine speed, slow or
fast.
B. Overheating in load connecting devices.
C. Sparking or arcs from generator.
D. Loss of electrical output.
E. Damaged receptacles.
F. Engine misfire.
G. Excessive vibration.
H. Enclosed compartments, or confined areas.
I. Flame or smoke.
J. Rain, snow or wet conditions.
K. Operator non-attendance.
WARNING Check fuel system on a
regular basis. Look for signs of leaks, deterioration,
chafed or spongy fuel hose, loose or missing fuel hose
clamps, damaged fuel tank or a defective fuel shut-off
valve. Correct any defects before operation.

STARTING ELECTRIC MOTORS
EXTENSION CORDS
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.
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.
Current/Power Maximum Extension Cord Length
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.

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 winding might also be
damaged.

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.

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.
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.
BEFORE STARTING
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 post located on the control panel. Do not
connect to a water pipe or a ground used by a radio
sy stem .
1. Make sure the generator is positioned on firm
l evel surface.
2. Check the crankcase for oil and maintain at a
proper level.
3. Check fuel level and fill tank with fresh unleaded
gasoline if necessary. Allow for gasoline expansion by
never filling fuel tank completely to the top. Always
wipe up and remove any spilled gasoline.
4. Make sure that the exhaust fumes are directed
away from people.
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.
STARTING
OPERATING SPEED
1. Disconnect all loads to generator.
2. Move engine on-off lever located on engine to
the I position.
3. For cold engine, move choke lever to full choke
position. For a warm engine, move choke lever to to
half choke or run position.
4. Grasp recoil handle and pull.
5. When engine starts, move choke lever to run
position.
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 to ensure
the generator is working properly before connecting a
load to the generator. Failure to do so could result in

STOPPING
1. Disconnect all loads to generator.
2. Move engine on-off switch to the O position.
ENGINE CARE
Refer to your Tecumseh Owner’s Manual for
proper care and maintenance.
CAUTION NEVER change oil on a hot
engine, the hot oil could cause severe burns.
GENERATOR CARE
The generator head is a two pole, 3600 RPM, 60
Hz, brushless, revolving field and synchronous type
with one sealed radial roller bearing. The rotor of the
generator head is directly connected to the engine
crank shaft and the stator is rigidly coupled to the
engine casting via the generator head casting.
Exercising The Generator - The generator
should be operated every four weeks. Warm the
unit up by starting the engine and letting it run for 10 to
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 engine 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 FACTORY
APPROVED REPAIR PARTS. Obtain all factory parts
from Customer Service at 1-800-270-0810.
A. Bearing - The bearing used in these generators
is a heavy duty sealed ball bearing. 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.
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.
