study the following precautions and insist
those working with you, or for you, follow
them.
2. In order to provide a better view, certain
photographs or illustrations in this manual
may show an assembly with a safety shield
removed. However, equipment should never
be used in this condition. Keep all shields in
place. If shield removal becomes necessary
for repairs, replace the shield prior to use.
3. Replace any safety sign or instruction sign
that is not readable or is missing. Location of
such safety signs is indicated in this manual.
4. Never use alcoholic beverages or drugs which
can hinder alertness or coordination while us-
ing this equipment. Consult your doctor about
using this machine while taking prescription
medications.
5. Under no circumstances should young
children be allowed to work with this
equipment. Do not allow persons to use or
assemble this unit until they have read this
manual and have developed a thorough
understanding of the safety precautions
and of how it works. Review the safety
instructions with all users annually.
6. This equipment is dangerous to children and
persons unfamiliar with its operation. The
operator should be a responsible, properly
trained and physically able person familiar
with machinery and trained in this equipment's
operations. If the elderly are assisting with
work, their physical limitations need to be
recognized and accommodated.
7. Never exceed the limits of a piece of machin-
ery. If its ability to do a job, or to do so safely,
is in question - DON'T TRY IT.
8. Do not modify the equipment in any way. Un-
authorized modication may result in serious
injury or death and may impair the function

2.3 SAFETY TRAINING
1. Safety is a primary concern in the design and
manufacture of our products. Unfortunately,
our efforts to provide safe equipment can
be wiped out by a single careless act of an
operator or bystander.
2. In addition to the design and conguration of
equipment, hazard control and accident pre-
vention are dependent upon the awareness,
concern, prudence and proper training of
personnel involved in the operation, transport,
maintenance and storage of this equipment.
3. It has been said, "The
best safety feature is an
informed, careful opera-
tor." We ask you to be that
kind of an operator. It is the
operator's responsibility to read and under-
stand ALL Safety and Using instructions in the
manual and to follow these. Accidents can be
avoided.
4. Working with unfamiliar equipment can
lead to careless injuries. Read this manual
before assembly or using, to acquaint
yourself with the machine. If this machine
is used by any person other than yourself,

5.5 CONTROLS
Before starting to work, all operators should fa-
miliarize themselves with the location and func-
tion of controls.
1. Engine:
Read the engine manufacturers operator's
manual before starting for more detailed
instructions.
a. Ignition Key Switch (Electric Start):
This key switch controls the electrical
power to the engine electrical system.
Turn the switch clockwise to turn the elec-
trical system ON and the engine will run.
Turn further against the spring-loaded
detent to engage the starter. Release
the key once the engine starts and it will
return to the run position. Turn counter-
clockwise to stop.
b. Indicator Light/Circuit Breaker Reset:
The LED indicator light and circuit moni-
tors the engine electrical circuit. It will
illuminate when the circuit exceeds its
preset value and trip the breaker. Depress
the indicator to reset the breaker and the
light will go out.
c. Choke:
This push/pull knob controls the position
of the choke. Pull the knob out to close the
choke for starting when the engine is cold.
Push the knob in to open the choke as the
engine warms.Always push the knob fully
in when operating the machine.
d. Ignition Switch (Manual Start):
This switch controls the electrical power
to the engine electrical system. Turn the
switch counter-clockwise to turn OFF.
Turn clockwise to the rst position for
ON.
e. Choke:
This lever controls the position of the
choke. Slide the lever to the left to close
the choke valve for starting when the
engine is cold. Slide to the right to open
the choke as the engine warms. Always
open the choke fully when operating the
machine.

f. Throttle:
This lever controls the engine RPM. Move
the lever to the left to increase the engine
speed and right to decrease. Always run at
maximum engine RPM when operating.
g. Fuel Shut-Off Valve:
This valve controls the ow of fuel to the
engine. Turn the valve at right angles to
the fuel line to turn the fuel off and parallel
to turn the fuel on.
h. Starting Rope:
This retracting rope and T-bar is used to
turn the engine over for starting. Grasp the
T-bar rmly and pull the rope sharply to start
the engine. Close the choke if the engine is
cold.

2. Electrical Controls:
a. 120 Volt, 20 Amp Outlets: These outlets
are used to provide 120 Volt, 20 Amp power
to the customer.
b. 120 Volt, 30 Amp Outlets: These outlets
are used to provide 120 Volt, 30 Amp power
to the customer.
c. 120/240 Volt Outlet: This outlet is used
to provide 240 Volt power to the customer
(GF5000A/EA - 20 A, GF6000A/EA - 25 A,
GF7200EA - 30 A).
d. 120 Volt Circuit Breakers: These push
switches are used to reset the circuit
breakers to the adjacent 120 Volt outlets.
Push the switch to reset the breaker if it is
tripped.
e. Master Breaker: This two position switch
controls the master breaker for the gen-
erator. Move the switch up to engage the
breaker before starting or when the breaker
trips and down to disengage the breaker.
f. Hour Meter: This meter measures and
displays the time the generator has been
operating.
g. Automatic Idle Control: This six-position
rotary switch sets the operating time of the
generator before the engine goes to low
idle. It is a convenience to the user that
requires intermittent use that the generator
continue to run at full RPM or power. It is
more economical to run at low idle but then
the RPM must come up to speed to provide
full power.

5.6 FIELD OPERATION
Although the Portable Generator is easy to use, each
operator should review this section to familiarize
himself with the detailed safety and operating
procedures. When using this machine, follow this
procedure:
1. Clear the area of bystanders, especially small
children.
2. Review and follow the Pre-Operation Checklist
(see Section 5.4).
3. Position the generator in the following manner:
a. Level to minimize the chance of spilling
fuel.
OPERATING SAFETY
• Read and understand operator's manual before
starting. Review safety instructions annually.
• Stop and disable engine, remove ignition key
and place in your pocket and wait for all mov-
ing parts to stop before servicing, adjusting or
repairing.
• To prevent electrical shocks, do not operate
this generator in the rain or with wet hands. It
should be grounded in damp or highly conduc-
tive conditions.
• Close and secure all guards, deectors and
shields before starting and operating.
• Do not connect the generator to a commercial
power line.
• Do not operate with damaged or defective
extension cords, or power cords. Never oper-
ate any electrical equipment with damaged or
defective cords.
• Do not operate this generator in areas with poor
ventilation. The exhaust fumes contain carbon
monoxide, a poisonous, odorless, invisible gas.
Prolonged exposure can lead to unconscious-
ness and death.
• Do not refuel the engine while it is in opera-
tion or still hot. Do not refuel the engine near
open ames, pilot lights or sparking electrical
devices (e.g. power tools, welders or grinders).
Do not operate the generator near ammable
products.
• The engine should be refuelled in a well-lit area.
Avoid fuel spillage.
• Never allow children or unauthorized people
to operate or be around this machine.
• Keep the working area clean and free of de-
bris to prevent tripping. Operate only on level
ground.
• Do not cover the generator while in operation.
Overheating can result in damaged equip-
ment.
• For storage, do not cover the generator until it
has cooled down completely.
• The ambient temperature should not exceed
100° F/40° C.
b. In a dry area to prevent shocks and
shorts.
c. Away from all flammable liquids and
fumes.
d. With a ground to minimize the chance of
