DANGER
Observe User Manual
► Please observe the safety instructions in the user manual for all work!
CAUTION
Use the correct blanking plugs
► Only use blanking plugs in the machine which match the manufacturer's compressed
air connection. A tight fit cannot be guaranteed for other blanking plugs.
► We recommend the use of blanking plugs made by Festo.

► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation. Observe the instructions in section 1.2 "Preparatory Work..." [}15].
NOTICE
Recommendation
► We recommend that you always perform these tasks from the opposite side, over the
other gantry. You may need to use a stepladder or something similar to help you.
► Unplug the incremental encoder press-fit connection from the head interface. In this case
make a note of the position to make clear assignment easier later on.
► Unthread the connection cable as far as the incremental encoder (2).
► Loosen the three screws (4) fastening the X read head mounting bracket with incremental en-
coder and carefully remove the incremental encoder with the mounting bracket.
► Remove the two screws (3) and then remove the incremental encoder.
