Function Speed Control Full Load / Idle Mode - Kärcher HDS 9/50 De Tr1 Service Manual

9.14.4 Function speed control full load / idle mode

If pressure is applied to the casing (5) during operation of
the pump, the piston (3) is pressed against the spring (2)
and thus pulls the Bowden cable (6) into the casing. This
way the speed control on the motor is changed and the
motor reaches the maximum speed.
