Safety devices
Safety devices serve to protect against injuries and
must not be changed or circumvented.
Relief valve with pressure switch
When the lever on the handgun is released the pres-

sure jet ceases. When the lever is pulled the pressu-
re switch switches on the pump again.
Moreover, the relief valve prevents the permissible
operating pressure from being exceeded.

Operation

!
Serious danger!
Vehicle tyres and tyre valves can be damaged by
the high-pressure jet and become perforated. The
first sign of this is a discoloration of the tyre. When
cleaning them maintain a distance of at least 30 cm.
Never grasp the power plug with wet hands.
Before each use check the power cord and power
plug for damage. Have a damaged power cord re-
placed immediately by an authorized Kärcher ser-
vice point or an electrical specialist.
Before each use check the high-pressure hose for
damage. Replace a damaged high-pressure hose
immediately.
!
Danger of injury!
Owing to the water jet emerging from the high-pres-
sure nozzle a recoil force operates on the handgun.
Ensure you have a secure footing and hold the hand-
gun and spray lance firmly.
If necessary wear protective clothing for protection
against return spray.
