Faults
DANGER
Risk of electric shock.
Work on electrical plant only to be carried
out by qualified electricians.
Switch the plant to voltage-free before per-
forming any work; in order to do so, switch
the system to "0" at the main switch and se-
cure against restart.
Who may remedy faults?
Operator
Work designated with the sign "Operator"
may only be carried out by persons who
have been instructed in the safe operation
and maintenance on the wash plant
Electricians
Persons with a professional training in the
electro-technical area.
Customer Service
Work designated with the sign "Customer
Service" may only be done by the fitters of
Kärcher Customer Service or fitters who
have been authorised by Kärcher.
DANGER
Risk of electric shock. Switch the system
voltage-free, in addition, switch the main
switch to "0" and secure it against restart-
ing.
Risk of injury due to compressed air escap-
ing unexpectedly. Compressed air contain-
ers and compressed air lines also remain
under pressure after the plant has been
switched off. It is absolutely necessary to
reduce the pressure before starting work
on the plant. To do this, turn off the com-
pressed air supply and use the manual op-
eration to move the wheel wash system in
and out until the pressure has been re-
leased. Then check the pressure gauge on
the maintenance unit for absence of pres-
sure.
Risk of injury from high-pressure water jet
unexpectedly emerging. It is absolutely
necessary to depressurize the high-pres-
sure system prior to working on the system.
