Pipe / Fitting P250-355/8-12B:
 For pipe-to-fitting connections, the two spacers must be
engaged in both middle clamping elements, and the heating
element take-off device is suspended into the left 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
element. Thus, the movable clamping element can be shifted on the rod as space
requirements demand during clamping.
When some fittings are being processed in certain positions, such as horizontal bends or
welding necks, it is necessary to remove the heating element take-off device.
Pipe / Fitting P500-630/18-24B Plus:
 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
element. Thus, the movable clamping element can be shifted on the rod as space
requirements 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
machine. 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.
P500-630/18-24B Plus: Verify the direction of rotation! The machines were polarised
to turn clockwise before leaving our factory!
 Switch on trimmer unit. The planing discs should turn in the cutting direction; if not, use
suitable 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.
 Press the control lever leftward and slowly increase the milling pressure to the optimal value.
When the milling drive is overloaded or at rest, raise the machine and reduce the
pressure.
