Intended use
The module was designed for linear movement of useful loads into any desired position, where the load does not react in an manner endangering persons, property or the enviroment as a result of this manipulation.
The module is intended for installation in a machine. The require-ments of the applicable guidelines must be observed and complied with.
The module may be used only in the context of its defined applica-tion parameters.
Any other use or use exceeding that specified is an infringement of appropriate use. The manufacturer bears no liability for damage resulting from such use.
Environmental and operating conditions
• Use the module only within its defined application parame-ters( 6, Page 13) "Technical Data" and catalog
• Do not expose the module to excessive vibration and / or shock.
• Sicherstellen, dass die Umgebung sauber ist und die Umge-bungstemperatur den Angaben gemäß Katalog entspricht. War-tungs- und Schmierintervalle beachten ( 11, Page 25)
• Make sure that the environment is free from splash water and vapors as well as from abrasion or processing dust. Excepted are modules that are designed especially for contaminated en-vironments.

Compressed air supply
NOTE
• Observe the requirements for the air supply "Technical Data" Technical data
• The operation with lubricated or unlubricated compressed air is fully permitted (observe the following note).
• Use connection cables with the same or larger cross section as the connection threads.
• Before installing connecting cables, remove dust, dirt or par-ticles by blowing the equipment.
• Avoid penetration of sealant into the pipeline network.
• Take the pneumatic components just before mounting out of the packaging.

Commissioning
NOTICE
Before commissioning! Please read these instructions carefully. Only with the knowledge of this manual errors can be pre-vented, and trouble-free operation is ensured.
• Check technical specifications.( 6, Page 13) "Technical Data".
• Do not use the linear module until you have determined that it is in perfect operating condition, after having checked for com-pliance with all permissible operating parameters.
• Regulate the operating speed of the cylinder with regulator valves ( 7.2, Page 15). Starting slow, increase the speed until the desired operating speed is reached.
• When mounting loads, take measures to prevent impermissible forces and torques.
• Do not subject the linear module to loads outside of the oper-ating range.
– Excessive loads can result in damage or inaccuracy of the guide unit.
– The maximum permissible loads are specified in our stan-dard catalog.

Re-adjustment of the end position sensor is not necessary. Tighten the clamping screw (5) again after adjusting the desired stroke.
Max. permissible screw tightening torque for property class 8.8:
• LM 25 1.5 Nm
