DANGER
CARBON MONOXIDE
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.

2.1 Laws 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.

doors and windows are open. Only use this generator OUTSIDE and far away from windows, doors, and vents.
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

3.1 Determining 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

3.2 Installation

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.

Operation GP 2600

3.3 Generator 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.

3.4 Grounding 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.

3.5 Operating 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.

wc_tx000558gb.fm 19
Page 20
Operation GP 2600

3.6 Use 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.

3.8 Ground 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.

3.9 Circuit 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.
