10 Ground Fault Circuit Interruptor (GFCI)
NOTICE
Running the pressure washer without water will cause the
pump to overheat, which may result in permanent damage.
Always connect and turn on the water supply to the pump
before starting the motor. Do not operate the pressure
washer without water.
Disconnecting the Water Hose
To disconnect the water hose:
Switch off the pressure washer, @ 11.2.
Disconnect the pressure washer from the power supply.
Shut off the water supply.
Pull the spray gun trigger to relieve pressure.
Lock the spray gun trigger.
Remove the water hose (1).
Unscrew the coupling (2).
10.1 Testing the Ground Fault Circuit Interruptor
WARNING
To reduce the risk of electrocution, always test the GFCI
each time you plug in your unit and before you start work.
The pressure washer has an electrical protection
mechanism. The ground fault circuit interruptor (GFCI) is an
important safety device that is intended to protect the
operator and bystanders from the risk of electric shock or
electrocution. It is designed to quickly and automatically
disconnect a circuit when it detects that the electric current
is not balanced.
A GFCI does not provide protection against unexpected or
dangerously high current, therefore it cannot replace a fuse
or protect against overheating or fire risk due to over-current
(overload) or short circuits if the fault does not lead to
current leakage.
To test the ground fault circuit interruptor (GFCI):
Connect the power supply cord to a properly installed
electrical outlet that matches the voltage and electrical
frequency stated on the pressure washer's rating plate.
The indicator LED (2) on the GFCI should be ON.
Depress the TEST button (1).
The LED (2) should shut OFF.
If the LED does not shut OFF after depressing the TEST
button, the GFCI is not working. Disconnect the pressure
washer from the power supply and have it inspected by an
authorized STIHL servicing dealer before further use.
Before starting work, always reset the GFCI as described
in chapter @ 10.2.
