Pull the knob (11), swing the machine upward, and allow the locking bolts to click in.
Make sure that both bolts are engaged in the holes in the frame!
Pull the trimmer lock (7) to the front and swivel the trimmer (1) to the back.
Swivel heating element (2) to the back.
Connect power plug of trimmer unit (1) and heating element (2) to the power supply stated
on the type plate.
The red "Stand by" diode on the heating element lights up, which means: voltage is being ap-
plied. Switch on the heating element on the hand grip using the large press-button (lights up
green) and set the desired temperature using the "+" or "-" button (160°C to 285°C / 320°F to
545°F).
Heating is displayed on the hand grip by the yellow diode. Horizontal bars also appear on the
temperature indicator. The yellow diode goes out shortly before reaching the set nominal tem-
perature (tolerance +/-3°C / 5.4°F) and the green one lights up. The heating element is usable
after a further 10 minutes. Note: upon first reaching the nominal temperature the set value can
be exceeded for short time.
Check the temperature using an external temperature measuring instrument. If there are devia-
tions it means that the heating element must be re-calibrated: press the "+" and "-" button simul-
taneously and then set the difference using the "+" or "-" button.
If "Er1" appears this means the electronics are defective. For "Er2" the resistance thermometer
is either defective or not connected. Send the device to an authorised ROTHENBERGER spe-
cialist workshop
Very hot – Do not touch! The heating element can reach a temperature of
approx. 290°C / 554°F!

Measures for preparing welding
For pipes which are smaller than the maximum diameter of 160 mm to be welded the clamp-
ing inserts / bracket of the corresponding diameter are to be inserted in the main clamps.
Be sure to use the correct reduction clamping inserts! The upper reduction clamp-
ing inserts, or the bracket + lower reduction clamping inserts + support fork in-
serts, must match!
Version A: Open the clamping plates (8) and swing them to the rear position. Press the up-
per reducing insert against the rear stop and tighten the tensioning screw (8.2).
Version B: Open the clamping plates (9) and insert the upper clamping element (9.1) and
tip forward (the clamping pin is the rotation axis).
Insert the lower reduction.
Supports bracket inserts are to be inserted in the support brackets (10) and fastened with
the knurled screws.
Insert the plastic pipes or fittings to be welded into the clamps.
Put the support brackets (10) under the pipe or fitting, loosen knurled head screw and move
the support bracket accordingly, turn if required and thighten knurled head screw.
For straight pipes to be welded align the support brackets with the front surface
parallel to the centre of the groove in the tables!
Version A: Close the clamping plates (8). Using the adjusting nut (8.1) adjust the tension
and bring the handle to the end position until the maximum force is reached.
Version B: Untwist the clamping plates (9), swing the bracket backward and bring the
clamping device to the operating position. When tensioning, be sure that the wings of the
wing nut are always at 90° to the axis of the pipe.
Check whether the workpieces are tight in the clamping tool by moving the workpieces to-
gether. When applied max. welding pressure must not slip through pipes! Thus, a successful
welding process it is ensured.
