1. Important Information
EC Declaration of Conformity (see MRL Appendix II A)
1.1. Manufacturer explanation
Rules and standards complied with:
Machinery guidelines 89/392/EWG, 91/368/EWG
Manufacturer:
Montech AG, Gewerbestrasse 12 CH-4552 Derendingen
Tel. [phone], Fax [phone]
1.2. Purpose
GPP grippers are used where workpieces have to be regularly gripped internally or externally, for
material handling purposes.
Under all circumstances attention must be paid to the performance limits, as given in the technical data in
these instructions.
1.3. Hazards
The use of GPP grippers in an installation is only permissible when they are guarded by MOVING, ISO-
LATING PROTECTIVE DEVICES as per EN 292-2, para.4.2.2.3. Failure to comply with this protective
measure can result in injury due to fingers being squeezed, for example.
1.4. Additional information
The aim of the present User Manual is to enable users to employ gripper GPP correctly and safely. Should
further information be required in relation to your particular application, please contact the manufacturer.
When reordering User Manuals, it is essential to quote the reference number, the product name and
serial number.
