Functional description

The high-pressure pipe cleaning devices are self-priming compact devices for cleaning pipes,
drains, downpipes, house service connections, rain downpipes and for cleaning work in ducts of
the following diameters:
HD 11/90 and HD 13/100 dia. 40 – 150 mm up to a maximum length of 30 m
HD 17/190 and HD 19/180B dia. 40 – 200 mm up to a maximum length of 40 m
All types are equipped with:
• Continuously variable pressure regulation
• A pump with 3 ceramic plungers running in an oil bath, run-dry safe, stainless steel valves,
brass pump housing, leak refeed, pressure gauge with bar/psi scale, self-priming up to 2 m
• Integrated suction injector, solvent feed outside of the pump, thus no damage to the high-
pressure seal.
When using a washing lance (accessory item no.: 76068 / 76073) the high-pressure cleaners al-
so serve to clean the surfaces of motor vehicles, buildings, machines, etc.
3.3 Start of operation
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!
 Unroll the high pressure hose with nozzle loop-free and lead it into the pipe to be cleaned at
least up to the marking.
When using a washing lance (accessory item no.: 76068/76073) please connect this to the high-
pressure hose by means of an adaptor. In doing so remove the dead man's switch (10) with
connecting hose (12) and connect the connecting hose (7) to the reel connection (11).
 Switch on the device or actuate the motor (HD 19/180B) (see petrol motor instruction manu-
al).
In doing so the high pressure hose with nozzle must at least be at the marking in
the pipe and may only be removed after the device has been switched off.
 Press the washing lance/dead man's switch in order to activate the spray of liquid.
