Rules for safe 4E-180 series generator operation

Failure to follow these instructions may lead to serious injury or even death.
This equipment is to be operated by trained and qualified personnel only.
Do Not operate this equipment before reading this information.

• Do not work alone.

• Know how to stop the engine quickly and understand how to operate all of the controls.

• Check engine oil level prior to each use and add as necessary before starting engine.

• Always wear personal protective clothing, safety glasses and other personal protection devices according

to the rules of the work area.

• Read, understand and follow any and all brand specific information provided by the particular engine or

motor manufacturer.

• Generators are a source of potentially lethal high voltage and should be operated by qualified personnel

only.

• Do not operate electrical equipment standing in water, with wet hands or in the rain. Electrical shock

could occur causing bodily harm or even death.

• Use adequately sized connecting cable for extension cords.

• Maintain electrical cords in good condition and have damage repaired by qualified personnel prior to use.

Damaged, frayed or exposed wiring can result in electrical shock causing severe bodily harm or even
death.

• To reduce fire hazards and provide adequate ventilation keep internal combustion engines at least 3ft

(1m) away from buildings, combustible materials and other equipment during operation. Operate the
equipment on level or very nearly level surfaces. Do not put the engine powered generator indoors while
the engine is still hot.

• Always use extreme caution when handling flammable liquids. Fumes are combustible. Always refuel only

in a well ventilated area away from sparks and open flame. Never refuel a hot or running engine. Fire or
explosion could result from fuel vapors or fuel spilled on a hot engine. Stop the engine and allow engine
to cool before re-fueling. Do not smoke around the machine while refueling. Promptly clean up any
spilled fuel. Failure to follow these recommendations could result in bodily harm or death.

• This generator is equipped with a ground terminal and the generator must be grounded to an external

grounding source. Ground the generator from the lug provided by the manufacturer according to Federal,
State and local codes for site conditions. Failure to properly ground this equipment can result in serious
bodily harm or death.

• Operate internal combustion engine-driven generators only

carbon monoxide build-up and / or excessive heat due to lack of air flow. This can result in serious bodily
harm or even death.

• Never operate generator in an explosive atmosphere. This can result in serious bodily harm or death.

• Check all tools powered by the generator for proper ground or circuit protection.

• Always wear rubber boots and gloves as added protection when operating a concrete vibrator or similar

device immersed in a water based solution.

Emergency Preparedness:

• Know the location of the nearest fire extinguisher and first aid kit.

• Know how to contact the nearest ambulance and/or Fire Department

This portion of the manual covers the Generator Section (driven power

producing section) only.

Diesel Engine, Baldor Electric Motor or other power source is provided by the specific manufacturer of
the drive unit and was included with the generator as a separate manual. Based upon the power source
of your high-cycle generator, please refer to the specific manufacturer’s manual for information on the
drive unit.

Please read this manual, all safety information and the drive unit manual in their entirety before

operating the generator.

WARNING! When operating, the High-Cycle Generator produces an

Manuals for the drive section using a Honda Gasoline Engine, Yanmar

electrical current and can cause injury or even death if used

improperly.

The Denver High-Cycle Generator is designed to produce 3-Phase, 180 Hertz (High Cycle) electricity and
can be wired for either 115 volt or 230 volt (230 volt is the factory setting) and is intended to be used to
provide the power to a high-cycle concrete vibrator that has been designed to operate on the supplied
power. The Denver High-Cycle Generator cannot be used to provide power to single-phase equipment
or 3-Phase equipment that requires a power supply that is something other than 180 Hertz (i.e. 60
Hertz)

WARNING! Making modifications to the Generator Section will

void the warranty and may result in injury or even death.

The electricity produced by the Generator Section is supplied to two (2) 7410 receptacles located on the
front of the Generator Section (see Fig. 1). The receptacles are designed for a 4-pronged, 3-phase, 7411
twist-lock plug. To insert the plug, make sure that the prongs of the plug line up to the appropriate slots
in the receptacle and push all the way in. Once the plug has been fully inserted, twist it to the right
(clockwise) to lock the plug into the receptacle. To remove the plug from the receptacle, twist the plug
to the left (counterclockwise) to unlock and then pull the plug straight out to remove.

Grounding

5

WARNING! Before using the generator make sure that it is properly

grounded according to National, State and local codes per site

conditions. Consult with a competent, qualified electrician. Failure

to properly ground the generator is a potential shock hazard and

may result in injury or death.

Before starting the generator or connecting power tools to the receptacles, make sure that the
generator is properly grounded according to National, State and local codes per site conditions. Ground
the generator using the grounding lug located on the cover plate of the Generator Section (see Fig. 1) to
a grounding electrode such as a ground rod with minimum #8 gauge wire. Resistance to ground should
measure 500 ohms or less. Note: As normally configured, the engine/generator assembly is isolated
from the frame using rubber mounts.

Simply placing the frame on the ground will not provide a proper grounding connection.

Per OSHA Fact Sheet, “Grounding Requirements for Portable Generators”

Bonding Versus Grounding…

“Bonding and grounding are separate requirements for generators and other electrical distribution
systems. Grounding means the connection, or the establishment of a connection, of an electric circuit or
equipment to reference ground, which includes the generator’s frame. Bonding is the intentional
connection between the grounded circuit conductor (neutral) and the grounding means for the
generator, which includes the generator’s frame. Thus, effective bonding of the neutral conductor to the
generator’s frame is also a concern for the safe use of the equipment. As with grounding terminal
connections, proper bonding of the neutral terminal of a power receptacle may be confirmed via testing
by a competent electrician with the correct equipment, and the ohmic resistance should measure near
zero and must not be intermittent, which indicates a loose connection.”

As a source of additional information, please see the complete OSHA Fact Sheet “Grounding
Requirements for Portable Generators” regarding proper grounding of portable generators included as
a separate flyer in the literature sent with the generator.

Grounding by placing the frame on the ground may be achieved if the engine/generator assembly is
bonded to the frame. If the generator has a wheel kit or is positioned in such a manner that the frame is
elevated and/or isolated from the earth then grounding must be accomplished by using the grounding
lug and a grounding electrode such as a ground rod per National, State and local codes per site
conditions; otherwise, proper grounding will not be achieved.

Consult a competent and qualified electrician when determining how to properly ground or modify

this generator assembly per National, State and Local codes per site conditions.
