This document is a supplement
to the Operating & Maintenance
Instructions for the engine that
powers this on-board generator.
This POWERLINK system includes the engine, an inverter,
and a Ground Fault Circuit Interrupter (GFCI). The GFCI is a
receptacle which protects against electrical shocks. A GFCI
detects ground faults.
If a ground fault is detected, the GFCI will interrupt the circuit
when it detects a difference in electric current. One type of
ground fault occurs when electricity flows through a person to
an earth ground instead of following the normal safe path.
Please be aware that the GFCI is not fail proof. Most brands are
susceptible to failures from power surges such as nearby
lightening strikes. For this reason and for your protection,
Briggs & Stratton makes the recommendation that the GFCI
gets tested before every use of the POWERLINK system. If
found to be defective, it must be replaced by an Authorized
Service Dealer before further use.
Also, please note that the GFCI does not protect from serious
electrical shocks resulting from contact between the system
neutral (white wire) and the “hot lead” (black wire). See listed
warnings within this document for further clarification on
hazards and how to avoid them.
The POWERLINKE Operating Instructions
contain safety information to:
• Make you aware of hazards associated with the
POWERLINK On-Board Generator System.
• Inform you of the risk of injury associated with those
hazards, and
• Tell you how to avoid or reduce the risk of injury.

metal in both straight slots of a receptacle)
• Current overloads
• Line-to-line short circuits
WARNING
WARNING
The POWERLINK On-Board Generator System produces
electricity that could result in death, serious injury and/or
property damage if proper precautions are not followed.
Never handle any kind of electrical cord or device while
standing in water, or while barefoot, or while hands and/or feet
are wet.
Do not operate unit:
• in rain.
• if electrical cord or device, which is plugged into the GFCI
receptacle over heats.
• if electrical output is lost.
• if flame, spark or smoke is observed while unit is running.
Maintain and use proper sized electrical cord sets and extension cords per electrical device specification. Use cords rated
for no less than 15 amps.
Use cords which are in good condition. Never use worn, bare,
frayed or otherwise damaged cord sets.
Avoid contact with bare wires, terminals, and damaged cords.
Keep extension cord lengths at minimum possible length. Long
extension cords draw additional power.
Running the POWERLINK On-Board Generator System
produces heat.
Severe thermal burns can occur on contact.
Avoid contact with hot surfaces, such as the inverter.
DANGER
The engine used in the POWERLINK On-Board
Generator System gives off carbon monoxide, an odorless,
colorless, and poisonous gas.
Breathing carbon monoxide can cause nausea, fainting, or
death.
Never run POWERLINK On-Board Generator System in an
enclosed area, even if doors or windows are open.
THE POWER IN POWERLINK
The POWERLINK On-Board Generator System will operate
continuously at 1000 watts output, and up to 1500 watts for brief
periods. Operating at loads above 1000 watts continuously may
trigger the POWERLINK system to reset and halt the electrical
output needed to power the load. The system produces 120 volts, 60
cycle AC electrical power. Prior to connecting any electrical device,
ensure compatibility of operating voltage and frequency
requirement.
The POWERLINK system output remains 120 volts throughout the
entire engine speed range. Output wattage increases with engine
speed. Select the engine speed that will power the electrical device
satisfactorily without triggering the POWERLINK reset.
CAUTION: Damage may result if the equipment
operates outside of a +/–10% voltage variation from the
rated voltage of 120V.
POWERLINK OPERATING
INSTRUCTIONS
[1] Start the engine and set the desired engine speed.
[2] No load should be applied to the engine, (Power-Take-Off

to the GFCI receptacle after reset.
TESTING THE GFCI
To ensure proper operation, and avoid injury the GFCI receptacle
should be tested before every use.
[1] Have the POWERLINK system running and the power reset.
[2] Plug in a lamp or radio for verification that electrical power is
present.
[3] Press the GFCI TEST button in order to trip the system and
stop the flow of electricity.
[4] If the device is still being powered, the GFCI is not working
properly. Seek an Authorized Service Dealer.
[5] If the power goes off, the GFCI is working properly. To restore
power, press the RESET button.
CAUTION: Do not connect a battery charger, or charge
batteries from POWERLINK. This could cause
damage to the battery charger or the POWERLINK
system.
Electrical Operating Power Loss
The POWERLINK system has safety features to protect the
system and the operator. The electrical output of the POWERLINK
system will shut down at any electrical overload caused by
temperature or a system overload.
On an overload, the reset opens and disconnects electrical power to
the GFCI receptacle, tripping the system. A manual reset switch,
located on the tractor, has been installed to reset the electrical output
of the POWERLINK system. Once reset, operating power is
returned and the work load can be reconnected.
If the system continually trips, causing the operator to reset,
increase engine speed. If engine is running at top speed and the
system is still tripping, the system is being overloaded. Decrease the
load.
If power does not resume after reset, it may be a thermal overload.
Wait 15 minutes before actuating the reset.
The electrical operating output will also cease if there is a ground
fault. The GFCI receptacle will trip to protect the operator. See also,
Resetting the POWERLINK System.
Do not perform any modifications to
