This voltage (19-22 VAC) is then sent to the control box that
contains three rectifying diodes:

GA-4.5R/GA-4.5RA — LOAD APPLICATION
Single Phase Load
Always be sure to check the nameplate on the generator
and equipment to insure the wattage, amperage and
frequency requirements are satisfactorily supplied by the
generator 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

determined by multiplying nameplate
voltage by the nameplate amperage.
3. LARGE MOTORS
Submersible pumps, table saws etc.
WATTS = VOLTAGE x AMPERAGE
The power factor of this generator is 1.0 See Table 2 below
when connecting loads.
Total the running wattage and multiply by 3.
Example:
A conveyor belt runs at 8 KW
use a 24 KW generator.

Figure 2A. Generator Controls and Components
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 MQ service dealer.
3. Idle Control Switch – This unit is provided with an
automatic idle control 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-4.5R/GA-4.5RA — GENERATOR REFUELING
DANGER - REFUELING HAZARD
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 generator is placed
in a truck bed with a plastic liner, REMOVE generator from truck
bed and place on ground (Figure 3) to refuel. This possibility
exist of
fire
or
explosion
due to static electricity.

GA-4.5R/GA-4.5RA — INSTALLATION
Outdoor Installation
Install the generator in a area that is free of
bystanders
generator is on secure level ground so that it cannot slide
or shift around. Also install the generator 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 generator inside tunnels and
caves. The engine exhaust contains
noxious elements.
, and
overhead obstructions
WARNING - LETHAL EXHAUST GASES
. Make sure the
debris
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 generator
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 generator to
ground the generator.
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.
Mounting
The generator should always be mounted on a flat level
surface to isolate vibration of the generator when it is
running. DO NOT place the generator on slopes, the
possibility exists that the generator could slide.
NEC articles 250-64(b) and 250-66 set the following
grounding requirements:
1. Use one of the following wire types to connect the
generator 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 generator (Figure 4) connect the
ground cable between the lock washer and the nut on
the generator 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-4.5R/GA-4.5RA A.C. GENERATOR — OPERATION & PARTS MANUAL — REV. #1 (11/27/06) — PAGE 19
GA-4.5R/GA-4.5RA — INSTALLATION
Connecting the Ground
The nut and ground terminal on the generator should always be used to connect the generator 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).

GA-4.5R/GA-4.5RA — PRE-INSPECTION
General Inspection Prior to Operation
Ground Power Tools
When using power tools or electrical equipment requireing AC
power from the generator, make sure connecting (power tool)
cable has a ground pin as shown in Figure 5.
Figure 5. Ground Cables/Plugs
Extension Cable
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 generator 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.

To protect the generator from an overload always place the main

Maintenance
Perform the scheduled maintenance procedures as defined by
Table 6 and below:
DAILY
■
Thoroughly remove dirt and oil from the engine and control
area. Clean or replace the air cleaner elements as necessary.
Check and retighten all fasteners as necessary. Check the
gearbox for oil leaks. Repair or replace as needed.
WEEKLY
■
Remove the fuel filter cap and clean the inside of the fuel
tank.
■
Remove or clean the filter at the bottom of the tank.
■
Remove and clean the spark plug (Figure 25), then adjust
the spark gap to 0.024 ~0.028 inch (0.6~0.7 mm). This unit
has electronic ignition, which requires no adjustments.
Figure 25. Spark Plug Gap
Cleaning the Fuel Strainer
Clean the fuel strainer if it contains dust or water. Remove
dust or water in the strainer cap and wash it in gasoline.
Securely fasten the fuel strainer cap so that fuel will not
leak. Check the fuel strainer every 200 hours of operation or
once a month.
