Using a generator indoors CAN KILL YOU IN MINUTES.
Generator exhaust contains carbon monoxide (CO). This is a poison you cannot see or
smell. If you can smell the generator exhaust, you are breathing CO. But even if you cannot
smell the exhaust, you could be breathing CO.
•NEVER use a generator inside homes, garages, crawlspaces, or other partly enclosed
areas. Deadly levels of carbon monoxide can build up in these areas. Using a fan or
opening windows and doors does NOT supply enough fresh air.
•ONLY use a generator outside and far away from windows, doors, and vents. These
openings can pull in generator exhaust.
Even when you use a generator correctly, CO may leak into the home. ALWAYS use a
battery-powered or battery-backup CO alarm in the home.
If you start to feel sick, dizzy, or weak after the generator has been running, move to fresh
air RIGHT AWAY. See a doctor. You could have carbon monoxide poison.

2.1Laws Pertaining to Spark Arresters
Notice: State Health Safety Codes and Public Resources Codes
specify that in certain locations spark arresters be used on internal
combustion engines that use hydrocarbon fuels. A spark arrester is a
device designed to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified and rated by
the United States Forest Service for this purpose.
In order to comply with local laws regarding spark arresters, consult
the engine distributor or the local Health and Safety Administrator.

BACKFEED FROM THE GENERATOR INTO THE PUBLIC POWER
DISTRIBUTION SYSTEM CAN CAUSE SERIOUS INJURY OR
DEATH TO UTILITY WORKERS!
Improper connection of generator to a building’s electrical system can
allow electrical current from the generator to backfeed into utility lines.
This may result in electrocution of utility workers, fire, or explosion.
Connections to a building’s electrical system must be made by a
qualified electrician and comply with all applicable laws and electrical
codes.
If connected to a building’s electrical system the generator must meet
the power, voltage, and frequency requirements of the equipment in
the building. Differences in power, voltage, and frequency
requirements may exist and improper connection may lead to
equipment damage, fire, and personal injury or death.
Familiarity and proper training are required for the safe operation of the
machine. Machines operated improperly or by untrained personnel
can be dangerous. Read the operating instructions contained in both

3.Operation
3.1Determining Power Requirements
This generator is designed to operate single-phase, 60 Hz appliances
running at 120 VAC. Check the nameplate or label provided on tools
and appliances to make sure their power requirements match the
power output of the generator.
Some appliances and tools require a surge of current when starting.
This means that the amount of power needed to initially start the
equipment is larger than the power required to keep it running. The
generator must be capable of supplying this “surge” current. Other
types of appliances require more power than is actually stated on their
nameplate.
The information in “Approximate Starting Power Requirements” is
offered only as a general guideline to help you in determining power
requirements for different types of equipment. Check with your nearest
Wacker Dealer, or contact the manufacturer or dealer of the tool or
appliance, with questions regarding its power requirements.
NOTICE: If a tool or appliance does not reach full speed within a few
seconds when switched on, turn it off immediately to avoid damage.
Approximate Starting Power Requirements
•Incandescent lights and appliances such as irons and hot plates, which
use a resistive-type heating element, require the same wattage to start
and run as is stated on their nameplates.
•Fluorescent and mercury lamps require 1.2–2 times their stated
wattage to start.
•Electrical motors and many types of electrical tools often require a
large starting current. The amount of starting current depends on the
type of motor and its use.
•Most electrical tools require 1.2–3 times their stated wattage for
starting.
•Loads such as submersible pumps and air compressors require a very
large force to start. They need as much as 3–5 times the wattage
stated on the nameplate in order to start.
If the wattage is not given for a particular tool or appliance, it can be
calculated by multiplying its voltage and amperage requirements:
Single Phase: VOLTS x AMPS = WATTS

3.2Installation
Place the generator in an area where it will not be exposed to rain,
snow, or direct sunlight. Make sure it is positioned on firm, level
ground, so it will not slide or shift. Position the engine exhaust away
from areas where people may be present.
The surrounding area must be free from water and moisture. All
components must be protected from excessive moisture.

poison you cannot see or smell. NEVER use this generator inside a
tunnel or a trench.

Page 18
OperationGP 2600
3.3Generator Derating
All generators are subject to derating for altitude and temperature.
Internal combustion engines, unless modified, run less efficiently at
higher altitudes due to the reduction of air pressure. This translates
into a lack of power and thus reduction in generator output.
Temperature affects both engine and generator performance. As
temperature increases, an engine will run less efficiently and more
resistance will be found in electrical components. Therefore, as the
temperature increases, the output of the generator decreases. Altitude
also affects the cooling capacity of air—the higher the altitude the less
dense the air is and thus the lower its ability to transfer heat.
For every increase in altitude of 500 m (1650 ft.) above 1000 m (3300
ft.), the output of the generator will be reduced by 3%. For every
increase of 5° C (9° F) in ambient temperature above 40° C (104° F),
the output of the generator will be reduced by 3%. Use the tables
shown for altitude and temperature deration factors. It may be
necessary to consider both altitude and ambient temperature deration
factors to determine true generator output.

3.4Grounding the Generator
A ground connection (a) is located on the generator frame. For proper
operating safety, this ground terminal must be connected to a good
ground source. This ground connection must comply with National
Electrical Code standards, and state and local regulations.
3.5Operating Heavy Loads
Limit operations requiring the maximum rated output of 2600 Watts to
20–30 minutes. For continuous operation, do not exceed the
continuous rated output of 2250 Watts.
NOTICE: DO NOT exceed the current limit specified on the control
panel for any receptacle.

Page 20
OperationGP 2600
3.6Use of Extension Cords
When a long extension cord is used to connect an appliance or tool to
the generator, a voltage loss occurs—the longer the cord, the greater
the voltage loss. This results in less voltage being supplied to the
appliance or tool and increases the amount of current draw or reduces
performance. A heavier cord with a larger wire size will reduce the
voltage loss.
Damaged extension cords can cause electrical shock, resulting in
serious injury or death. DO NOT use worn, bare, or frayed cords.

3.8Ground Fault Interrupt (GFI)
The 120V, 20 Amp receptacle (a) is equipped with a ground fault circuit
interrupt (GFI). The GFI shuts off the power to the receptacle when a
ground fault occurs to a piece of equipment attached to the generator.
This GFI also protects the second 120V, 20A receptacle (c).
The GFI should be tested for proper operation every time the generator
is used.
To test GFI:
Start generator. Push TEST button (d) on receptacle in. The RESET
button (e) will pop out. Power is now off at the receptacle. If the RESET
button does not pop out, the GFI is not working. Do not run generator
until the problem can be corrected. To restore power to receptacle,
push the RESET button in.
If the RESET button pops out during operation, stop the generator and
check it and equipment for defects.
3.9Circuit Breaker
The generator is also protected by a 20-Amp circuit breaker (b) located
on the control panel.
The circuit breaker protects the generator from severe overloads or
short circuits. If the circuit breaker opens, turn the engine off
immediately and determine the cause before restarting. Check the
appliances and tools attached to the generator for defects and make
sure their power requirements do not exceed the power rating of the
generator or the current limit of the receptacles.
When the circuit breaker opens, the breaker button will pop out. To
reset circuit breaker, push button in.
