2 Function and application When compressed air is applied to connection 2, the piston of the micro parallel gripper HGPM-... is pressed against a mechanism. A mechanism transfers the longitudinal mo ve- ment of the piston to the gripper jaws 6. Gripper fingers are fastened to the gripper jaws. When the jaws open, they can grip work loads by the inner contour; when the jaws close, they can grip work loads by the outer contour. The micro parallel gripper HGPM-... is single- acting and depending on the mechanism it can be used for gripping from the outside or from the inside. When the gripper is exhausted, a reset spring returns the gripper jaws to the starting posi- tion: – gripper fingers open: on HGPM-...-EO-... – gripper fingers closed: on HGPM-...-EZ-... The HGPM-... is designed for gripping and holding work loads in handling processes. Fig. 2

3 Conditions of use Please note Incorrect handling can lead to malfunctioning. S Observe the following instructions in order to ensure correct and safe use of the product. S Compare the values specified e.g. for pressures, forces, torques and tempera- tures with your actual application. S Make sure that there is a supply of correctly prepared compressed air. S Please observe also the relevant technical regulations, as well as national and local regulations. S Remove all transport material such as protective wax, foils, caps and cartons. The waste materials can be disposed of in separate containers for recycling. S Take into acccount the prevailing ambient conditions. S Pressurize your complete system slowly (e.g. with a safety sart-up valve type HEL-...). S Observe the warnings and instructions on the product and in these operating instructions. S Use the product in its original condit ion without undertaking any modifications. Fig. 4 LF-... LR-... Fig. 5 Fig. 6HGPM-...-G.. Festo HGPM-...-G.. 0103NH English

4 Fitting Mechanical components Fastening the gripper fingers S Use gripping fingers as short and as light as possible. S Screw two fastening screws into the threaded holes in each of the gripping jaws. The maximum screw depth must not be exceeded. Otherwise the function can be affected. The different gripping jaws have the following connection threads: HGPM-08 HGPM-12 Jaw width (toleranced) 3 +0,05 mm 4 +0,05

Thread size M2.5 M3 Max. permitted screw depth (only with HGPM-...-EO-..) 4mm 4mm Max. tightening torque (short-term) 0.4 Nm 0.8 Nm Fig. 8 Fitting the HGPM-... Please note High acceleration forces in the longitudinal direction of the gripper (e.g. when fitted on moving par t s such as the DGP-...) reduce the gripping force. S Make sure that the resulting work load forces lie within the reduced gripping force range. Fig. 7 Fig. 9HGPM-...-G.. Festo HGPM-...-G.. 0103NH English

5 Commissioning Complete system S Slowly pressurize your complete system. This will prevent any uncontrolled move- ments. The safety start-up valve type HEL-... or HEM-... can be used for slow pressuriza- tion during the starting phase. Individual unit S Observe the permitted values for the following (see catalogue): – the maximum gripper force as a factor of the lever arm and the eccentricity – the maximum permitted gripping times – the maximum gripper finger weight force. Warning Moving parts can cause injury to hands and fingers. S Therefore make sure that: – nobody can place his/her hand between the gripper fingers – no objects lie within the range of the gripper fingers. S Start a test run – at first with slow positioning movements – then under application conditions. The HGPM-... must hold the work load securely. S Conclude the test run. The gripper should now be exhausted. Fig. 11 Fig. 12HGPM-...-G.. Festo HGPM-...-G.. 0103NH English

6 Care and maintenance S If necessary, clean the exterior of the HGPM-... with a soft cloth. The permitted cleaning medium is soap suds, max. + 60 °C. 7 Dismantling and repairs Warning If there is a drop in pressure, the work load will suddenly slide down. S Make sure that the gripper is not holding a work load when it is exhausted. 8 Accessories Designation Type Safety valve HEL-.../HEM-... Adapter plate AM-.../HAPG-... Fig. 14 Fig. 13HGPM-...-G..
