Shutdown; Care And Maintenance - Rothenberger HD 11/90 Instrucciones De Uso

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. 76068 / 76073) and chemical cleaning agent.
 Remove the dead man's switch (10) with connecting hose (12) and connect the connecting
hose (7) to the reel connection (11).
 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 by means of an adaptor 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 high-pressure 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!

Shutdown

 Release the dead man's switch, the spray jet stops.
 Switch off the device or deactivate the motor (HD 19/180B) (see petrol motor instruction
manual).
 Stop the supply of water (turn off tap).
 Venting: Press the dead man's switch shortly to relieve the pressure.
 After using the washing lance: unscrew the washing lance from the high pressure hose and
store in an orderly fashion.
 Emptying the pump: press the dead man's switch and switch on the motor for about 20 sec-
onds.
 Remove the power plug (HD 11/90, HD 13/100, HD 17/190).
 Wind the high pressure hose in an orderly fashion onto the reel.
 Winter: Store the pump in frost-free places.
 Clean the water filter.

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.
Check that the sieve is clean every time before start-up! Please
ensure that the water is clean when taking in at outside locations
The hose cross-section must be at least ½" =12.7 mm (free pas-
sageway)!
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 fluid 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%.
