1
Turn the laser mains isolator ON.
2
Turn the pointing diode ON.
Note
If you have more than one shutter and pointing diode fitted, please ensure
the correct pointing diode is ON
3
Using a suitable piece of white card, check if a red beam is present at the workpiece
ie. at the end of the PIPA fibre and focus head assembly.
4
If no beam is present, loosen the screws (item 2) holding the pointing diode
assembly.
5
Reposition the diode assembly, on the oversized holes, looking for a beam at the
workpiece.
6
When you have a beam present at the workpiece tighten the screws (item 2).
7
Using a 1.5mm allen key, locate the three adjusters (item 4) on the diode body.
8
Adjust each one in turn to optimise for the brightest beam at the workpiece.
Note
If there is no change in brightness, loosen all three adjusters to allow the
diode to move freely.
9
When optimised for the maximum brightness, tighten all three adjusters on to the
diode.
