Note: The autotuning function could cause the details under "CFG" to deviate minutely. Should
hunting occur, the autotuning function can be activated while the heating plate is cold (set
the menue item "S.tu" to "2" (two) in CFG menue, the system automatically resets the pa-
rameter to "0" (zero).
For lifting the milling equipment and the heating element, use lifting device 53410 or 53323, or a
suitable tool.
3.2.2 Measures for preparing welding
 Pipes smaller than the maximum welding range (diameter) of the machine, mount the
adapter clamping inserts suited for the pipe diameter with the screws found in the accesso-
ries kit.
The set is consisting of six wide-surface shells and two small-surface shells.
In so doing, please observe that the small-surface shells are mounted to the two lower external
main clamps. These are used in the left basic clamping element below and above only for pipe
to pipe bend connections.
 Insert the plastic pipe or fitting in the clamping device (use dolly with longer pipe < 2,5m sec-
tions) and tighten brass nut on the upper clamps. Adjust brass nuts (tighten or loosen) to
compensate for any ovalness.
For pipe-to-pipe connections, the two spacers must be engaged in

both left clamping elements (standard configuration at delivery).
Attention: Under no circumstances should the spacers be installed diagonally offset!
The pipes are each held by two clamping elements.
For pipe-to-fitting connections, the spacers must be swivelled to the

other side and engaged in the middle clamping elements.
Attention: Under no circumstances should the spacers be installed diagonally offset!
 The pipe is inserted into three clamping elements, and the fitting is held by one clamping el-
ement. Thus, the movable clamping element can be shifted on the rod as space require-
ments demand during clamping.
 Verify secure fit by moving the workpieces together.
Stay a safe distance away from the machine. Do not stand or reach into the ma-
chine. Keep other people away from the work area!
 Check to ensure that the heating plate has reached the setpoint operating temperature.
CAUTION! To guarantee uniform heat distribution over the entire heating element, the
heating element must not be used until at least 10 minutes after it reaches the target
temperature. Check and verify the temperature with a temperature meter and readjust if
necessary!
 Position the electrical trimmer between the two workpieces.
Verify the direction of rotation! The machines were polarized to turn clockwise before
leaving our factory!
 Switch on trimmer unit. The planing discs should turn in the cutting direction; if not, use suit-
able tools to change over the phase inverter in the mains plug.
Risk of serious injury! During operation trimmer unit, stay a safe distance away
from the machine, and do not reach into the rotating knife. Use trimmer in working
position only and return it into the designated carrying frame immediately after use.
Ensure that the safety switch functions properly at all times to avoid any accidental
starting of the trimmer away from the basic machine.
 Turn the pressure adjustment valve counter-clockwise all the way.
