element. Thus, the movable clamping element can be shifted on the rod as space
requirements demand during clamping.
Stay a safe distance away from the machine. Do not stand or reach into the
machine. Keep other people away from the work area.
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!
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.

An excessively high milling pressure can lead to overheating and damage to the
miller drive. When the milling drive is overloaded or at rest, raise the machine

valve.
Should the joint surfaces show any misalignment, repeat the trimming procedure. For best
results the workpiece ends should not be mismatched by more than 10% of the wall
thickness and the maximum gap between the joint surfaces no more than 1.0 mm. This
recommendation does not release you from your obligation to observe national welding
guidelines. Clear away any remaining shavings with a clean brush.
CAUTION! Do not touch the trimmed, ready to weld surfaces. Ensure that the surfaces are
free of any and all containments and foreign objects!
