The speed of the engine was carefully adjusted at

the factory so that the generator produces the proper

voltage and frequency. For normal usage, the speed

setting should not be changed. If the generator

is being run continuously on a very light load, it is

often advisable to lower the operating speed slightly.

Whenever making any speed adjustments check the

unit with a voltmeter or tachometer and be sure the

speed is correct.

Lower voltage may damage both the generator and

any load connected to it. Running the engine at ex-

cessively high speeds results in high voltage, which

may signiﬁ cantly shorten the life of appliances being

used.

Output voltage should be checked periodically to

ensure continued proper operation of the generat-

ing plant and appliances. If the generator is not

equipped with a voltmeter, 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.

CONNECTING THE LOADS

APPLYING THE LOADS

Allow the engine to warm up for two or three minutes

before applying any load. This will allow the engine

to reach normal operating temperature and oil to cir-

culate throughout the engine. A short warm-up time

will permit the engine to work more efﬁ ciently when

the load is applied and will reduce the wear in the

engine, extending its life.

Receptacles have been provided to allow loads to

be connected to the generator. The loads should

be added one at a time. If a large motor is being

started or multiple motors are being started, they

should be started individually and the largest should

be started ﬁ rst.

CAUTION: EQUIPMENT OVERLOAD

Keep the generator load within the generator and

receptacle nameplate rating. Overloading may cause

damage to the generator and/or the loads .

Most electric tools and appliances will have the volt-

age and amperage requirements on their individual

nameplates. When in doubt consult the manufac-

turer or a local electrician. The nameplate amperage

rating for electric motors can be misleading. See

“Starting Electric Motors” in Unit Capabilities (page

4).

These engine-generator sets are inherently self reg-

ulating based on engine speed. The engine governor

will automatically adjust itself to the load. No harm

to the generator will result if it is operated with no

load connected. Proper utilization of the receptacles

located on the control panel is necessary to prevent

damage to either the receptacles or the generator.

The generator is a limited source of electrical power,

therefore pay special attention to the receptacle

and generator ratings. The nameplate rating can be

obtained through a single receptacle as long as the

receptacle amperage rating is not exceeded.

GROUNDING

All units must be grounded. Drive a 3/4 or 1” cop-

per pipe or rod into the ground close to the engine-

generator set. The pipe must penetrate moist earth.

Connect an approved ground clamp, to the pipe.

Run a no. 10 Awg wire from clamp to the generator

ground lug on the “end cover”. Do not connect to a

water pipe or to a ground used by a radio system.

The engine-generators covered in this manual were

designed for portable use. DO NOT OPERATE THIS

GENERATOR INDOORS. The unit should be stored

in a warm dry location. During a power outage, move

the unit outdoors to a ﬂ at dry location such as a

driveway or sidewalk.

WIRING

Plug your tools such as drills, saws, blowers, sump

pump and other items to be powered directly into

the generator receptacles. Before plugging in all

the tools and cord sets, recheck the rating of the

generator set. Be sure it can handle the intended

load and is compatible with the voltage, phase, and

current ratings. ‘Hard Wiring’ this unit directly into a

temporary construction site electrical system is NOT

A SIMPLE DO-IT-YOURSELF JOB. For your safety

all wiring must be done by a qualiﬁ ed electrician and

conform to the National Electric Code and com-

ply with all state and local codes and regulations.

Check with local authorities before proceeding.

WARNING: PERSONAL DANGER

A fully isolated, double pole double throw manual

transfer switch must be installed any time a genera-

tor is being connected to an existing distribution

system.

1. These engine generator sets are designed for

portable heavy duty commercial use. Receptacles

are provided on the control panel to permit 120 and

240 volt portable appliances and tools to be plugged

directly into them. Please note that the 3-wire 240

volt receptacle(s) on these units are designed to

power only 240 volt tools. There are two hot leads

and a ground wire, but no neutral connection, in the
