3.2 Operation
Warning! The operation of the tube cleaning machine should only be carried out under full
compliance with all the instructions for the safety of persons and machinery!
 Position the machine at a distance of approx 1m from the opening of the tube to be cleaned
and fixed with the fixing brake (4).
 Slide guide hose onto the stay bolts (rear side of the machine housing) and fasten by means
of wing screws.
 Push spiral into the device and attach a suitable tool to the front. Select the appropriate tool for
the anticipated type of dirt blockage.
Caution! Before any further manual operations are carried out gloves must be worn!
 Start the motor as follows, reverse gear (1) must be turned in idling speed (N):
 turn switch (5) to "ON".
 open Fuel tap (6).
 Choke (7) to right position and pull the motor starter until the motor starts up.
 Close Choke (7), if the motor is in operating temperature.
 Regulate the throttle lever (8) 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 (R) and push the spiral slightly into the tube until a
resistance point is perceptible (blocked point)
 Pull the spiral out of the machine until a slight working bend is created.
 Operate the hand-lever (2b), the spirals will now start to rotate.
 Press the created working bend downward by hand in order to assert pressure in the
direction of the blockage.
Important: the screw should bore into the blockage and should not be pressed into the
blockage!
 Once the pre-stressed working bend has penetrated the tube, relieve the hand lever (2b) and
pull the spiral out of the machine in order to create another working bend.
 Form a working bend and repeatedly press the rotating spiral in the direction of the blockage
until the blockage has been removed.
If a tool has become jammed in the tube at the point of the blockage, switch the device to left-
hand motion and release the spiral from the blockage by moving forward and backward.
3.3 Removal of the tube blockage
 After successfully removing the blockage, use one hand to pull the rotating spiral out of the
tube until a slight bend is formed.
 Relieve the hand lever (2b) and push the spiral that has come to a standstill back into the
device.
 Operate the hand lever (2b) once more to make the spiral rotate again.
 Repeat these working sequences until all spiral segments have been removed from the tube.
