e. Always avoid hot muffl ers, exhaust manifolds,
and engine parts. They can cause severe
burns instantly.
f. The use of the engine-generator set must com-
ply with all national, state, and local codes.
TESTING POLICY
Before any generator is shipped from the factory, it
is fully checked for performance. The generator is
loaded to its full capacity, and the voltage, current
and frequency are carefully checked.
Rated output of generator is based on engineering
tests of typical units, and is subject to, and limited
by, the temperature, altitude, fuel, and other condi-
tions specifi ed by the manufacturer of the applicable
engines.
INTENDED USES
These engine generator sets have been designed
primarily for portable use. A 120 volt GFCI AC re-
ceptacle is provided in the end cover to connect your
loads (lights, portable tools, and small appliances).
This portable unit requires large quantities of fresh
air for cooling the engine and generator. For safety,
long life and adequate performance, these units
should never be run in small compartments without
positive fresh air fl ow.
RESTRICTED USES
DO NOT install and operate this generator in a small
compartment., i.e. generator compartments of ve-
hicles, motor homes or travel trailers. These com-
partments will not allow enough free fl ow of fresh
air to reach the engine generator set for cooling and
will cause the unit to overheat damaging both the
engine and generator. Small compartments will also
develop hot spots where there is very little air fl ow
and may cause a fi re.
PLEASE NOTE There are 3rd party companies
making enclosures for generators that have been
properly engineered. The use of these 3rd party
enclosures is acceptable as long as they have been
certifi ed and meet current code.
DO NOT attempt to operate at 50 cycles. These
units are designed and governed to operate at 60
cycles only.
UNIT CAPABILITIES
GENERATOR CONNECTIONS
This generator is designed for 120 volt alternating
current (AC) use only. A GFCI protected duplex out-
let is provided for connection to various loads.
Check the appliance or tool nameplate for the cur-
rent and voltage to insure compatibility. Although a
circuit breaker is provided, damage due to overload-
ing constitutes abuse and will not be warranted. Re-
fer to the generator nameplate for unit’s capabilities.
STARTING ELECTRIC MOTORS
Electric motors require much more current (amps) to
start them than to run them. Some motors, par-
ticularly low cost split-phase motors, are very hard
to start and require 5 to 7 times as much current
to start them as to run them. Capacitor motors are
easier to start and usually require 2 to 4 times as
much current to start them as to run them. Repul-
sion Induction motors are the easiest to start and
require 1 1/2 to 2 1/2 times as much to start them as
to run them.
Most fractional horsepower motors take about the
same amount of current to run them whether they
are Repulsion Induction (RI), Capacitor (Cap), or
Split-Phase (SP) type. The chart below shows the
approximate current required to start and run various
types and sizes of 120 volt 60 cycle electric motors
under average load conditions.

The fi gures given above are 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.
