Operation; Removal Of Pipe Blockages - Rothenberger R 140 B Bedienungsanleitung

Up to pipe diameter 150mm - 600mm, with max. length up to 140m, you can work with the
leverage unit by rod adapter (ref. 3.6). The assembly of the leverage unit will expand
significantly the working range.
The machine functions on the "Sectional Cable" principle, i.e., only as many spirals resp. rods as
necessary are coupled together. The power of the motor is transmitted to the spirals resp. rods
adapter via the clamp-mounting system by exerting pressure on the hand-lever.
We recommend the operating always with two men, because of the high working range of the
machine.
3.2

Operation

The machine should be positioned at a distance of approx. 1m from the entry to the pipe to be
cleaned and fixed with the fixing brake (4).
The spiral should now be inserted into the machine and coupled at the front by means of a
suitable tool. The tool should be selected to accord with the suspected type of fouling.
Important! Put on safety gloves before any other actions are
performed!
The reverse gear (1) must be turned in idling speed (1a)!
Now you can start the motor as follows:
- turn switch (A) to "ON"
- open Fuel tap (B)
Choke (C) to right position
-
- pull the motor starter until the motor starts up
close Choke (C), if the motor is in operating temperature
-
- regulate the throttle lever (D) until the necessary operating speed is achieved
- slide the spiral approx. 500mm into the pipe to be cleaned
reverse gear (1) turn to clockwise rotation (1b)
-
Note! All spirals and tools are effective working only in clockwise rotation.
spirals should be moved manually toward the point of fouling. Once a slight resistance is felt
(blockage), the spirals should again be pulled out the machine until an arc relative to the pipe
occurs. This so-called working arc (3) should be maintained with one hand (wear gloves!). The
hand-lever (2) is pressed down (2b), the spirals will now start to rotate.
Regulate the working speed at the throttle lever (D).
3.3

Removal of pipe blockages

The working arc (3) produced should be pressed downward by the operator, generating a
pressure towards the blockage with the drain-cleaning machine remaining in its position. The
working pressure resulting from the spirals intrinsic tension and manual pressure acts against
the blockage in the pipe.
Once the pre-tensioned working arc has penetrated into the pipe, the hand-lever (2a) should be
released and the spirals should be pulled again out the machine in order to create a new
working arc. This cycle of creation of a working arc and pushing of the rotating spirals towards
the blockage should be repeated until the blockage has been eliminated.
Note: If the tool is blocked in the pipe, the machine should be set to reverse and the
spirals disengaged from the blockage by means of backward and forward movements.
The machine should then be reset to forward (1a) and the spirals moved up to the
blockage again. The procedure for removal of the blockage should then be continued
as described above
