5 .3 .1 Bracket mounting procedure
To fit the compact chain brackets, refer to the diagram shown below and follow the
instructions carefully.
1. Choose the shortest support posts which will still allow the laser beam to pass
over or through the coupling. Insert the support posts into the bracket.
2. Fasten them in place by tightening the hex screws on the sides of the bracket
frame.
3. Place the bracket on the shaft or coupling, wrap the chain around the shaft
and feed it through the other side of the bracket: if the shaft is smaller than the
width of the bracket frame, insert the chain from the inside of the bracket as
shown in the diagram; if the shaft is larger than the bracket width, insert the
chain into the frame from the outside.
4. Catch the chain loosely on the anchor peg.
5. Turn the bracket thumbscrew to tighten the assembly onto the shaft.
6. Clip the loose end of the chain back onto itself.
The bracket should now be tight upon the shaft. Do not push or pull on the bracket
to check, since this could loosen its mounting.
To remove the brackets, loosen the thumbscrew, then remove the chain from its
anchor peg.
The compact chain-type brackets cover most situations, but in cramped or
special cases, other types of brackets may be required. Ask your PRÜFTECHNIK
representative for details.
