GA-3.6H Series — GENERAL INFORMATION
GA-3.6H Series Familiarzation
Generator
The Multiquip GA-3.6H series 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 2A
through 2E for the basic controls and indicators for the GA-
3.6H Series 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:
■ NEMA L14-20R, twist-lock receptacle,125/250V, 20 amps.
■ NEMA L5-20R, twist-lock receptacle, 125V, 20 amps.
■ NEMA L6-30R, twist-lock receptacle, 250V, 30 amps.
(GA-3.6HZ only)
■ NEMA L5-30R, twist-lock receptacle, 125V, 30 amps.
■ NEMA 5-20R, GFCI duplex receptacle,125V, 20 amps
(GA-3.6HA has two).
■ 13.5 amp main circuit breaker.
■ AC Voltmeter
■ G.F.C.I. Ground Terminal (GA-3.6HZ only)
■ Full Power Switch
■ Idle Control Switch
■ Operation Switch
Excitation System
The GA-3.6H 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 8.0 HP, air-cooled, 4-
stroke HONDA gasoline engine. Reference Table 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.F

GA-3.6H Series— 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 (Table 3)
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.

GA-3.6H Series— CONTROLS AND INDICATORS
1. Lifting Bail Eye – Attach a rope or chain to this lifting eye
when lifting of the generators is required. Never stand
underneath the generators 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 generators or power tools turn the generators
OFF and consult your authorized Multiquip service dealer.
3. Idle Control Switch – The 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
rocker switch in the "ON"
position (up) for normal operation.To turn-off the generators,
place the operation switch in the "OFF" position (down).

GA-3.6H Series — GENERATOR REFUELING
Figure 3. Generators 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 3) to refuel.This possibility exist of
fire or explosion due
to static electricity.

GA-3.6H Series — INSTALLATION
Outdoor Installation
Install the generator/welder in a area that is free of debris ,
bystanders , and overhead obstructions . Make sure the
generators is 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.
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.
Generators 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 generator. 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.
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.
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.
Pay close attention to ventilation when
operating the generators inside tunnels
and caves.The engine exhaust contains
noxious elements.
CAUTIONCAUTION
CAUTIONCAUTION
CAUTION
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.

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 4) and tighten the
nut fully. Connect the other end of the ground cable to a suitable earth ground (ground rod).
