3.1.3 Description of the LM 20/25 module
The LM 20/25 consists of the base body (1) with pneumatic connections (6) and
cylinder and the front plates (2) and back plates (3).
The stop positions are set by means of a stop screw (4). To query the limit positions
an inductive sensor with a diameter of 6.5 mm (not included in the scope of delivery)
can be fixed in the stop screw.
The movement at the limit positions is absorbed by a hydraulic shock absorber (5).

3.1.4 Intended use
The series of the linear module LM 20 and LM 25 is used for the linear movement of
rigidly mounted loads in non-explosions harzadous ambient and operating conditions
that are specified for this module; see catalogue technical.
NOTE
These Instructions montage should be read carefully before carrying
out any activity on or with the module.
The module may only be used in accordance with intended purpose.
Modification on the module that are not described in these Montage
Instructions or have not been approved in writing by Afag are not
permitted. In case of inexpert changes or improper assembly,
installation, operation, maintenance or repairs, Afag rejects all
liability.
CAUTION
Connection of compressed air and operation of pneumatic
systems may cause unpredictable movements which may.
Result in personal unjuri or damage to property.
When connecting compressed air for the first time make sure that all air chokes are
closed. Ventilate the system slowly.

3.1.5 Warranty
3.1.6 Areas of application
The Linear modules are exclusively for the linear movement in any position of
payloads at the forehead to record maximum 2-8 kg (LM 20) and 4-9 kg (LM 25)
designed, (see technical data). They can also be used in combination with other
modules than Pick and Place machines, the permissible load capacities should,
however, not be exceeded.
Any other use is regarded as inadequate.
NOTE
The manufacturer does not accept any liability for damage resulting
from such use. The risk is that of the user alone.
Intended use also includes paying attention to the Montage Instructions and
observing the maintenance and repair instructions specified by manufacturer.
The Linear module LM 20/25 may only be operated and serviced by correspondingly
trained personnel who have also profound knowledge of the dangers.
CAUTION
The applicable regulations for prevention of accidents and the
other generally accepted safety-relevant and occupational
safety and health regulations are to be followed.
The term of the warranty on Afag handling components and systems is:
 24 months following commissioning, but a maximum of 27 months following delivery.
 Wear parts (e.g. shock absorbers) are not covered by the warranty. *
The warranty covers the replacement or repair of defective Afag parts. No further claims will be
accepted.
The warranty will be voided in event of the following:
 Use for other than the intended purpose
 Failure to observe the notes on installation, commissioning, operation and maintenance in
the operating manual
 Improper installation, commissioning, operation and maintenance
 Independent repairs and constructional changes without prior instruction by Afag
Automation AG
 Removal of the serial number on the product
 Using the module without shock absorbers, or with defective shock absorbers
 Inadequate monitoring of wear parts
*A customer has the right to a defect-free product. This is also applicable for accessories and wear parts, if they are
defective.
However, wear does not fall within the scope of the warranty.
