Electrical connection

The  network  voltage  must  conform  to  the  voltage  indicated  on  the  tool  name  plate. 
Under  no  circumstances  should  the  tool  be  used  when  the  power  supply  cable  is  damaged.  A  damaged  
cable  must  be  replaced  immediately  by  an  authorized  Customer  Service  Center.  Do  not  try  to  repair the 
damaged cable yourself. The use  of  damaged  power  cables  can  lead  to  an  electric shock.

WARNING: Always use a Residual Current Device (RCD)  also known as a Ground Fault Circuit Interrupter 
(GFCI).  Use an RCD in a separate control box with one or more socket outlets in accordance with EN 
60309-2 with the earthing contact position 1 h. Always use this device whenever using the machine to  
reduce  the  risk  of  shock  hazards.  Test and  reset the   device before each use. Press the “Test” button 
to test. Press the “Reset” button to energize   the circuit to the machine.

WARNING: Always connect the plug into the wall socket with a drip loop. If  the cable leads downward 
directly into the wall socket, any water on the cable could run into the socket, causing a hazard.
