WARNINGWARNING
WARNING
WARNINGWARNING
Before connecting this generators to any building’s
electrical system, a licensed electrician must install an
isolation (transfer) switch.
Serious injury or death may result without this transfer
switch.
GA-6RE/GA-6REA FAMILIARIZATION
Generator
The Multiquip GA-6RE/GA-6REA generators have been
designed as a portable dual purpose power source for 60
Hz (single phase) lighting facilities, power tools, submersible
pumps and other industrial and construction machinery.
These generators are mounted on rubber vibration isolators
that have a steel base backplate which is attached to the
protective steel pipe carrying frame. The protective carrying
frame is made of steel tubing and fully wraps around the
generators to protect against damage. See Figures 3A
through 3E for the basic controls and indicators for the GA6RE/GA-6REA generators.
These portable generators are supplied with a electrical
control box
control box is also placed on rubber isolators.
Control Box
The control box is provided with the following:
■
120/240V twist-lock output receptacle (single phase).
. To reduce vibration caused by the engine, the
Excitation System
The GA-6RE/GA-6REA-series generators use a magnet
attached to a flywheel to produce AC voltage from a lamp
coil beneath the flywheel. As the magnetic passes the coil it
produces approximately 19-22 AC volts.
This voltage (19-22 VAC) is then sent to the control box that
contains three rectifying diodes:
z
Excitation (diode 1)
z
Battery (diode 2)
z
Slow Down (diode 3)
The AC voltage will pass through the excitation diode that
converts the voltage to DC power.
This DC power is then sent to the excitation windings housed
within the main windings commonly called the "stator".
This voltage is then transferred into the rotor through
induction. The rotor contains two diodes within it which rectify
the DC voltage and send it out through the main windings,
as AC voltage.
Alternator
The alternator, a brushless revolving-field type, is
permanently aligned to the engine through rigid coupling.
Engine
These generators are powered by a 11.5 HP, air-cooled, 4stroke ROBIN gasoline engine. Reference Table 2, for engine
specifications.

GA-6RE/GA-6REA — LOAD APPLICATION
Single Phase Load — 60 Hz
Always be sure to check the nameplate on the generators
and equipment to insure the wattage, amperage and
frequency requirements are satisfactorily supplied by the
generators for operating the equipment.
Generally, the wattage listed on the nameplate of the
equipment is its rated output. Equipment may require 130—
150% more wattage than the rating on the nameplate, as
the wattage is influenced by the efficiency, power factor and
starting system of the equipment.
To determine the running wattage for your load, multiply
the running wattage as indicated by steps 1, 2, and 3 below:
1. INCANDESCENT LOADS
Lights, heaters and similar appliances.
Total the running wattage and multiply by 1.
Example:
29 light bulbs @ 100W each = 2.9 KW
use a 3 KW generator.
2. SMALL MOTORS
Drills and other small power tools.
Total the running wattage and multiply by 2.
Example:
NOTE
If wattage is not given on the equipment's
name plate, approximate wattage may be
A 1 inch drill runs at 1 KW
use a 2 KW generator.
determined by multiplying nameplate
voltage by the nameplate amperage.
3. LARGE MOTORS
Submersible pumps, table saws etc.
WATTS = VOLTAGE x AMPERAGE

1. Lifting Bail Eye – Attach a rope or chain to this lifting eye
when lifting of the generator is required. Never stand
underneath the generator while it is being lifted. Place lifting
eye in down position when not in use.
2. AC-Voltmeter – This voltmeter indicates (with a mark) the
rated 60 Hz (single-phase) output voltage. In addition the
voltmeter can also be used as a diagnostic tool. If the
voltmeter indicator (needle) is below the rated voltage,
engine problems may exist (low/high RPM's). To prevent
damage to the generator or power tools turn the generator
OFF and consult your authorized Multiquip service dealer.
3. Idle Control Switch – These generators are provided with
an automatic idle control device for noise suppression and
reduced fuel consumption. The automatic idle control
automatically engages under a no-load condition. With the
automatic idle control switched “ON”, the engine revolutions
will automatically drop to about 2600 rpm (low-speed
operation) within 3 seconds after the load stops. When the
operation is resumed, the engine speed is automatically
increased to about 3600 rpm (high-speed operation) as
soon as the load is connected.

GA-6RE/GA-6REA — INSTALLATION
Outdoor Installation
Install the generator/welder in a area that is free of
bystanders
generators are on secure level ground so that it cannot slide
or shift around. Also install the generators in a manner so
that the exhaust will not be discharged in the direction of
nearby homes.
The installation site must be relatively free from moisture
and dust. All electrical equipment should be protected from
excessive moisture. Failure to do will result in deterioration
of the insulation and will result in short circuits and grounding.
Foreign materials such as dust, sand, lint and abrasive
materials have a tendency to cause excessive wear to
engine and alternator parts.
Pay close attention to ventilation when
operating the generators inside tunnels
and caves. The engine exhaust contains
noxious elements.
Mounting
The generators should always be mounted on a flat level
surface to isolate vibration of the generators when it is
running. DO NOT place the generators on slopes, the
possibility exists that the generators could slide.

Indoor Installation
,
Exhaust gases from gasoline engines are extremely
poisonous. Whenever an engine is installed indoors the
exhaust fumes must be vented to the outside. The engine
should be installed at least two feet from any outside wall.
Using an exhaust pipe which is too long or too small can
cause excessive back pressure which will cause the engine
to heat excessively and possibly burn the valves.
Eliminate the danger of deadly carbon monoxide gas.
Remember that exhaust fumes from any gasoline engine
are very poisonous if discharged in a closed room, but
harmless if allowed to mix with the outside air. If the
generators is installed indoors, you must make provisions
for venting the engine exhaust to the outside of the building.
Generator Grounding
To guard against electrical shock and possible damage to
the equipment, it is important to provide a good EARTH
ground. Always use the ground terminal on the generators
to ground the generators. Ground the generators from its ground
connector so that the resistance to ground is 500 ohms or less.
Article 250 (Grounding) of the National Electrical Code (NEC)
provides guide lines for proper grounding and specifies that
the cable ground shall be connected to the grounding system
of the building as close to the point of cable entry as
practical.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generators to earth ground.
a. Copper - 10 AWG (5.3 mm2) or larger.
b. Aluminum - 8 AWG (8.4 mm2) or larger.
CAUTIONCAUTION
CAUTION
CAUTIONCAUTION
An electric shock is apt to happen
when vibrators are used. Pay close
attention to handling when operating
vibrators and always use rubber
boots and gloves to insulate the
body from a short circuit.
GA-6RE/GA-6REA A.C. GENERATORS — OPERATION & PARTS MANUAL — REV. #0 (06/06/05) — PAGE 21
2. When grounding the generators (Figure 3) connect the
ground cable between the lock washer and the nut on
the generators and tighten the nut fully. Connect the
other end of the ground cable to earth ground.
3. NEC article 250-52(c) specifies that the earth ground
rod should be buried a minimum of 8 ft. into the ground.
GA-6RE/GA-6REA — INSTALLATION
Connecting the Ground
The nut and ground terminal on the generators should always be used to connect the generators to a suitable ground. The
ground cable should be #8 size wire minimum.
At the generator, connect the terminal of the ground cable between the lock washer and the nut (Figure 5) and tighten the
nut fully. Connect the other end of the ground cable to a suitable earth ground (ground rod).

General Inspection Prior to Operation
Ground Power Tools
When using power tools or electrical equipment requireing AC
power from the generators, make sure connecting (power tool)
cable (Figure 6) has a ground as shown in Figure.
Extension Cable
When electric power is to be provided to various tools or loads at
some distance from the generators, extension cords are normally
used. Cables should be sized to allow for distance in length and
amperage so that the voltage drop between the generators and
point of use (load) is held to a minimum. Use the cable selection
chart (Table 4) as a guide for selecting proper cable size.
