connecting cord, extension cord or plugs.
► Plug the mains plug of the connecting cord or extension 
cord into a properly installed, shockproof socket with the 
correct fuse rating.
► Connect the pressure washer via a residual current 
circuit breaker (30 mA, 30 ms).

WARNING
■ During operation, an incorrect mains voltage or incorrect 
mains frequency may result in an overvoltage in the 
pressure washer. The pressure washer may be damaged.
► Make sure that the mains voltage and the mains 
frequency of the power supply match the data on the 
rating plate of the pressure washer.
■ Electrical components may be overloaded during 
operation if more than one electric power tool is connected 
to a multiple socket. The electrical components may heat 
up and a fire may break out. This can result in serious 
injuries or death and damage to property.
► Only ever connect one pressure washer to one socket.
► Do not connect pressure washers to multiple sockets.

may be damaged and people may trip over it. People may 
be injured and the connecting cord or extension cord may 
be damaged.
► Route the connecting cord and extension cord so that 
the water jet cannot touch them.
► Route and mark the connecting cord and extension cord 
so that people will not trip over them.
► Route the connecting cord and extension cord so that 
they are not under tension or tangled.
► Route the connecting cord and extension cord so that 
they will not be damaged, kinked or crushed and will not 
be chafed.
