3.3 Start of operation (B)
The high-pressure cleaner must only be operated if all information on the
safety of people and the machine is observed!
The machines must not be positioned and operated in rooms subject to fire
and explosion hazards or in puddles. The devices must not be operated under
water!
Water connection facilities (ill. B-1)
 Use the hose clamp to fasten the water hose to the suction connection (A) on the pump.
Please note: only use clean water!
 Connect the water hose to the water supply and turn on the tap. The amount of water must
be adequate for the respective high-pressure cleaner type.
When drawing water in from a water tank, fasten the water intake hose (accessory item no.:
76066) to the intake adaptor (A) on the pump by means of the cap nut and insert the sieve (B)
into the water tank.
Please note: do not draw in dirty water. Sieve on the intake hose!
The maximum suction height is 2 m. The maximum water temperature amounts to 60°C.
Please observe the regulations of the water distribution company!
 Plug the line cord plug into the socket (except on HD 19/180B).
Please observe the necessary fuse protection in accordance with the current consumption of the
devices. When using cable drums, be sure to unwind the cable completely!
 Avoid loops when unwinding the high-pressure hose and nozzle and insert into the pipe to
be cleaned.
When using a washing lance (accessory item no.: 76088) please connect this to the high-
pressure hose by means of an adaptor.
 Switch on the device or actuate the motor (HD 19/180B) (s. petrol motor instruction manual).
In doing so, the high-pressure hose and nozzle are to be in the pipe and only
removed when the device has been switched off.
The on/off switch serves simultaneously as the motor-circuit switch and shuts down if the set
value (ampere) is exceeded.
Pipe cleaning nozzles are to be used depending on the type of contamination.
Use of chemical cleaning agents (ill. B-2)
Area of application: Heavily contaminated surfaces of houses, motor vehicles, paving tiles, etc.
Necessary for this application: Injector intake hose (accessory item no. 76067), washing lance
with control nozzle (accessory item no. 76088 / 76073) and chemical cleaning agent.
 Slide the adaptor (A) of the injector intake hose onto the hose connection (3) and insert the
chemical sieve (B) into the reservoir with the chemical agent.
 Connect the washing lance to the high-pressure hose and turn on the control nozzle (C).
The injector will now draw in the cleaning agent.
The chemical agent supply is shut down automatically when the control nozzle is closed.
 Allow the cleaning agent to act and rinse off subsequently at high pressure.
Chemical agent supply only up to a maximum hose length of 20 m! In this connection
please see accessory intake hose 10 m (item no.: 72810) and 20 m (item no.: 72812).
Please observe the regulations of the manufacture of the additive (e.g. protective
equipment) as well as the waste water regulations!
