3.3 Start of operation (B)

ENGLISH 13

Water connection facilities (ill. B-1)

 Use the hose clamp to fasten the water hose to the suction connection (A) on the pump.

 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.

The maximum suction height is 2 m. The maximum water temperature amounts to 60°C.

 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).

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).

3.4 Shutdown

 Switch the device off.

 Stop the supply of water (turn off tap).

 Remove air: for the washing lance – open the gun briefly, for high-pressure hose – switch

motor on briefly until the pressure has been released.

 Unscrew the washing lance and the high-pressure hose and store accordingly.

 Empty the pump: switch on the motor for approx. 20 seconds.

 Remove the power plug.

 Winter: Store the pump in frost-free places.

 Clean the water filter.

4 Care and Maintenance

Use the gauge glass to check the oil level every time before start-up (please observe hori-

zontal position). The oil level should be half way up the gauge glass.

14 ENGLISH

The first oil change should take place after 500 operating hours. Further oil changes after 1000

operating hours in each case. Type of oil: Castrol Formula RS.

Warranty of any kind shall expire if the pump is operated without a universal safety valve or if the

limiting values for temperature and speed are exceeded ("Guidelines for safety spray guns ").

The safety valve must be set in such a way that the maximum operating pressure cannot be ex-

ceeded by more than 10%.

For HD 19/180B only:

The petrol motor should be serviced and cared for in accordance with the manufacturer’s in-

structions.

The high-pressure cleaning devices must only be disassembled and repaired by trained special-

ised staff.

The ROTHENBERGER service stations or the manufacturer’s service department are available

to you. We are naturally able to provide you with spare parts without delay. Please contact your

dealer or the manufacturer.
