STOW G-4.5R — GENERAL INFORMATION  
STOW G-4.5R Familarization  
Circuit Breaker  
General Inspection Prior to Operation  
To protect the generator from an overload, a 2-pole, 15 amp  
This generator has been thoroughly inspected and accepted  
prior to shipment from the factory.However, be sure to check  
for damaged parts or components, or loose nuts and bolts,  
which could have become disloged in transit.  
circuit breaker is provided on the control panel. Make sure  
to switch this circuit breaker to the "OFF" position prior to  
starting the engine.  
Excitation System  
The STOW Model G-4.5R generator has been designed as  
a portable lightweight power source for 60 Hz (single-phase)  
vibrators, lighting facilities, power tools, submersible pumps  
and other industrial and construction machinery.  
The STOW G-4.5R generator uses a magnet attached to a  
flywheel to produce AC voltage from a lamp coil beneath  
the flywheel. As the magnet passes the coil it produces  
approximately 19-22 AC volts.  
This generator is powered by a 9.0 HP ROBIN air-cooled  
gasoline engine. The alternator, a brushless revolving-field  
type, is permanently aligned to the engine through rigid  
coupling.  
This voltage (19-22 VAC) is then sent to the control box that  
contains three rectifying diodes:  
z
z
z
Excitation (diode 1)  
Battery (diode 2)  
Slow Down (diode 3)  
The generator is 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  
generator to protect against damage.  
The AC voltage will pass through the excitation diode that  
converts the voltage to DC power.  
This portable generator is supplied with a electrical control  
panel. The control panel includes items as listed below.  
This DC power is then sent to the excitation windings housed  
within the main windings commonly called the "stator".  
Control Panel  
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.  
The generator control panel has the following componets:  
NEMA 5-20R, GFCI duplex receptacle, (120V, 20 amps)  
NEMA L5-20R, twist-lock receptacle (125V, 20 amps)  
NEMA L5-30R, twist-lock receptacle (125V, 30 amps)  
Engine  
The four-cycle air-cooled ROBIN gasoline engine is designed  
to meet every performance requirement of this generator.  
Reference Table 1, for engine specifications.

STOW G-4.5R — LOAD APPLICATION  
To determine the running wattage for your load, multiply  
the running wattage as indicated by steps 1, 2, and 3 below:  
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.  
1. INCANDESCENT LOADS  
Lights, heaters and similar appliances.  
Total the running wattage and multiply by 1.  
Example:  
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.  
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.  
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.  
Total the running wattage and multiply by 3.  
Example:  
A conveyor belt runs at 8 KW  
use a 24 KW generator.  
WATTS = VOLTAGE x AMPERAGE  
The power factor of this generator is 1.0 See Table 2 below  
when connecting loads.  
Table 2. Power Factor By Load  
CAUTION

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 2 ) as a  
guide for selecting proper cable size.  
Common power tools  
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.  
When using a combination of dual  
receptacles, total load should not  
exceed the rated capacity of the  
generator.

STOW G-4.5R — INSTALLATION  
Outdoor Installation  
Indoor Installation  
Install the generator in a area that is free of debris,  
bystanders, and overhead obstructions. Make sure the  
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.  
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.  
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.  
Generator Grounding  
Foreign materials such as dust, sand, lint and abrasive  
materials have a tendency to cause excessive wear to  
engine and alternator parts.  
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.  
CAUTION  
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.  
Pay close attention to ventilation when  
operating the generator inside tunnels and  
caves. The engine exhaust contains  
noxious elements.  
NEC articles 250-64(b) and 250-66 set the following  
grounding requirements:  
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.  
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 3) 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.

STOW G-4.5R — 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 5) and tighten the  
nut fully. Connect the other end of the ground cable to a suitable earth ground (ground rod).

STOW G-4.5R — PRE-INSPECTION  
General Inspection Prior to Operation  
Ground Power Tools  
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.  
When using power tools or electrical equipment requireing AC  
power from the generator, make sure connecting (power tool)  
cable (Figure 6) has a ground as shown in Figure.  
Never! use power tools or  
equipment that do not have a  
ground capability, the possibility  
exists of electrocution, electrical  
shock or burn, which can cause  
severe bodily harm or even  
DEATH!  
Main Circuit Breaker  
To protect the generator from an overload always place the main  
circuit breaker in the "OFF" position prior to starting the engine.

Placing the idle control switch in  
the down position allows the  
engine to operate at a maximum  
speed of about 3600 RPM's. When  
the idle control switch is place in  
the up position (ON), the generator  
will run at idle speed (2200 RPM's) until a load is applied, at that  
time the engine speed will increase to 3600 RPM's as long as  
the load is being applied. When the load is not in use, the engine  
speed will drop back to the idle mode after about 3 seconds.
