GA-6RE/GA-6REA — GENERAL INFORMATION
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 GA-
6RE/GA-6REA generators.
These portable generators are supplied with a electrical
control box . To reduce vibration caused by the engine, the
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).
■ 120V twist-lock receptacle (2) (single phase).
■ 120V GFCI single phase duplex output receptacles (GA-
6REA has two).
■ 21 amp main circuit breaker.
■ AC Voltmeter
■ Ground Terminal
■ Full Power Switch
■ Idle Control Switch
■ Operation Switch
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, 4-
stroke ROBIN gasoline engine. ReferenceTable 2, for engine
specifications.
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.

PAGE 16 — GA-6RE/GA-6REA A.C. GENERATORS — OPERATION & PARTS MANUAL — REV. #0 (06/06/05)
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.
If wattage is not given on the equipment's
name plate, approximate wattage may be
determined by multiplying nameplate
voltage by the nameplate amperage.
WATTS = VOLTAGE x AMPERAGE
The power factor of this generators is 1.0 See Table 3 below
when connecting loads.
NOTE
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:
A 1 inch drill runs at 1 KW
use a 2 KW generator.
3. LARGE MOTORS
Submersible pumps, table saws etc.
Total the running wattage and multiply by 3.
Example:
A conveyor belt runs at 8 KW
use a 24 KW generator.
Extension Cables
When electric power is to be provided to various tools or
loads at some distance from the generator, 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 (Tables
4 and 5 ) as a guide for selecting proper cable size.
The idle control device is operated at a
minimum load capacity of 100W. If the
load capacity is less than 100W, place
the idle control switch in the OFF position.
NOTE
Motors and motor-driven equipment draw much greater
current for starting than during operation. Always use an
adequate size extension cable which can carry the
required load.
CAUTIONCAUTION
CAUTIONCAUTION
CAUTION
When using a combination of dual
receptacles, total load should not
exceed the rated capacity of the
generator.

will provide 120V, 20 amps.(There are only on the GA-
6REA.)
7. 120V Output Receptacle – NEMA L5-20R twist-lock
receptacle will provide 120V, 20 amps, 60 Hz.
8. 120V Output Receptacle – NEMA L5-30R twist-lock
receptacle will provide (120V, 30 amps, 60 Hz.)
9. 120V/240V Output Receptacle – This NEMA L14-30R
twist-lock receptacle will provide (120V, 50 amps, or
240V, 25 amps, 60 Hz.)
10. Main Breaker – This 2-pole circuit breaker (240V/25 amps
or 120V/41.6 amps) protects the generator from short
circuiting or overloading. When starting the generator
always have the circuit breaker placed in the "OFF"
position.
11. Ground – This ground connection point should be
connected to a good earth ground (ground rod)
12. Battery – This unit is equipped with a 12 VDC battery.
Replace with only recommended type battery.
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.
4. Operation Switch – Place this
toggle switch in the "ON"
position (up) for normal operation.To turn-off the generators,
place the operation switch in the "OFF" position (down).

When the full power switch is in the
120V position, the 240V twist-lock
receptacle cannot be used .
NOTE
When the switch is in the 240 volt (down) position, you can
acess half of the rated power of the generating set at 120
volts from the GFCI duplex receptacle and up to half of the
rated power of the set at 120 volts from 120V twist-lock
receptacle; or full rated power of the set at 240 volts from
the 240V twist-lock receptacle.
13. Full Power Switch – The generators are provided with a
full power switch. Figures 3C and 3D show simplified wiring
diagrams of the dual voltage system.
When the full power switch is in the 120 volt (up) position,
you can access the
full rated power of the generator at
120 volts from the GFCI duplex receptacle and the120V
twist-lock receptacle, or a combination of both receptacles
as long as the total load does not exceed the generating
set capacity.

This ROBIN engine is equipped with
a low oil shutdown capability. A built
in sensor will automatically turn off
the engine should the oil level fall
below a safe operating condition.
Make sure the generators is placed
on level ground. Placing the generators on level ground will
ensure that the low oil sensor will function properly.

14. Fuel Cock Lever – Turn this lever downward to start
(down)the flow of fuel into the carburetor.Turn upward to
stop ( up ) the flow of fuel.
15. Spark Plug – Provides spark to the ignition system. Set
spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Clean
spark plug once a week.
16. Muffler/Heat Shield – Used to reduce noise and emissions.
NEVER touch this
heat shield when the generator/welder
is in use. Always allow time for the generators to cool down
before performing maintenance.
17. Choke Lever – Used for starting the engine.
Close the
choke lever when starting a cold engine or in cold weather
conditions.The choke enriches the fuel mixture.
Open the
choke lever if starting a warm engine or in warm weather
conditions.
18. Recoil Starter (pull rope) – Manual-starting method. Pull
the starter grip until resistance is felt, then pull briskly and
smoothly.
19. Engine Oil Filler Cap – Remove this cap/dipstick when
the adding of engine oil is required. See Table 5 for
recommended type engine oil.

GA-6RE/GA-6REA — GENERATOR REFUELING
Figure 4. Generator Refueling
Adding fuel to the tank should be done only when
the engine is stopped and has had an opportunity
to cool down. In the event of a fuel spill, DO NOT
attempt to start the engine until the fuel residue
has been completely wiped up, and the area surrounding the
engine is dry. If generators is placed in a truck bed with a plastic
liner, REMOVE generators from truck bed and place on ground
(Figure 4) to refuel.This possibility exist of
fire or explosion due
to static electricity.
