AVOIDING INCORRECT USE
To ensure correct use, the following actions are not permitted:
Any other than the permitted voltages and currents
Marking on surfaces which are live
Marking on transfers between materials (edge of PCB; between PCB and PCB tracks
Never exceed the max. working travel of 2 mm; this is to prevent damage to the gear motor
REPLACING THE MARKING PROBE
The replacement kit, which consists of a spring,
pin and lock, can be exchanged in the event of
wear (order no. SK 790-AWE).
To dismantle, remove the pin with pliers. Fit the
new parts in the replacement kit according to
the sketch. The lock has to be plugged onto the
needle with the beveled side. For this purpose we
can supply an insertion tool
(order no. WHE 1200/790) which presses the lock
into the gear shaft drill hole.
