F. Engi ne mi sfire.
G. Excessive vibration.
H. Enclosed compartments, or confined areas.
I. Flame or smoke.
J. Rain, snow or wet conditions.

WARNING Check fuel system on a
regular basis. Look for signs of leaks, deterioration,
chafed or spongy fuel hose, loose or missing fuel hose
clamps, damaged fuel tank or a defective fuel shut-off
valve. Correct any defects before operation.
WARNING Keep the fire extinguisher
close by your generator, and be familiar on how to use
it. Consult your local fire department for correct
extinguisher type.
INSTALLATION
OUTDOORS: Choose locations where the
generator will not be exposed to rain, snow or direct
sunlight. Position the generator on secure, level
ground so it will not tip or slide down a hill. Place the
generator so that the exhaust fumes will not be
directed towards people.
The installation site must be free from water,
moisture, or dust. All electrical components should be
protected from excessive moisture or the insulation
system will deteriorate and result in grounding or
shorting out the generating system.
Foreign matters, such as dust, dirt, sand, lint, or
abrasive materials can cause damage to the generator
head and engine if allowed into its cooling system.
NEVER install your generator inside confined
areas. Inside installation can cause health hazards or
death.
DANGER Remember, exhaust fumes are
deadly carbon monoxide gas, and must be vented to
the outside where there are no people. Cooling air of
sufficient amounts must be brought in and exhausted
out to ensure proper cooling of the engine and
generator head.
LOAD APPLICATION
It is important to determine the total electrical load
before it is connected to the generator. The two major
factors in determining the life of a generator head are:
heat build-up, caused by overloading the generator
and corrosive contaminants that attack the wiring
insulation. If the generator is overloaded, the wires
become excessively hot and cause the insulation to
break down, reducing its ability to resist corrosive
contaminants. Over time the effectiveness of the
insulation is eliminated and a dead short can result.
Always compare the generator nameplate data
with that of the equipment to be used to ensure that
watts, volts, amperage, and frequency requirements
are suitable for operating equipment. The wattage
listed on the equipment nameplate is its rated output.
However, some equi pment may requi re three to ten
times more wattage than its rating on the nameplate,
as the wattage is influenced by the equipment
efficiency, power factor and starting system. NOTE: If
wattage is not given on equipment nameplate,
approximate wattage may be determined by
multiplying nameplate voltage by nameplate
amperage.
VOLTS X AMPS = WATTS
Example: 120V X 5A = 600W
When connecting a resistive load such as
incandescent lights, heaters or common electric power
tools, a capacity of up to the generator full rated
wattage output can be used.
When connecting a resistive-inductive load such
as a fluorescent or mercury light, transformers or
inductive coils, a capacity of up to 0.6 times the
generators full rated output can be used.
Always allow the generator to reach operating
speed before a load is applied.
STARTING ELECTRIC MOTORS
Electric motors require much more current (amps)
to start than to run. Some motors, particularly low cost
split-phase motors, are very hard to start and require 5
to 7 times more current to start than to run. Capacitor
motors are easier to start and usually require 2 to 4
times as much current to start than to run. Repulsion
Induction motors are the easiest to start and require
1.5 to 2.5 times as much to start than to run.
Most fractional motors take about the same
amount of current to run them whether they are of
Repulsion-Induction (RI), Capacitor (Cap), or Split-
Phase (SP) type. The following chart shows the
approximate current required to start and run various
types and sizes of 120 volt 60 cycle electric motors
under various conditions.
