Safety Precautions and Guidelines for Use
3-jaw centric grippers
I. Qualifications of the operator
Persons with no experience in working with gripping installations are exposed to particular danger due to incorrect behaviour, particularly during set-up work due to the gripping movements and forces occurring. Gripping installations may therefore only be operated, adjusted or repaired by persons specifically qualified or trained for this work, or who have many years of experience in this work.
II. Risk of injury
For technical reasons, this unit may consist partly of sharp-edged individual parts. Particular care must therefore be taken to avoid injury when working on these parts!
1. Installed energy accumulators Moving parts preloaded with compression springs, tension springs of other springs or with other elastic elements represent a hazard potential due to their stored energy. Underestimating this potential can result in serious injuries due to projectile-like individual parts flying around uncontrolled. This stored energy must be relieved before further work can be carried out. Gripping installations to be dismantled must therefore be examined for such potential sources of danger using the corresponding assembly drawings. If the relief of this stored energy cannot be carried out without danger, the dismantling may only be carried out by authorised personnel.
2. Calculation of the necessary gripping forces If this gripping installation is intended to hold or clamp the workpiece against machining forces exerted from the outside, the machining forces involved in a given machining process must be determined and provided with a safety allowance commensurate with the calculation method and the machining operation. The gripping installation must then be able to generate at least the gripping forces calculated in this way.
3. Use of other/further clamping inserts/workpieces The necessary minimum clamping force must always be determined when using other clamping inserts or workpieces.
1.Clamping of other/further workpieces If special clamping sets are provided for this gripping installation (jaws, clamping inserts, systems, alignment elements, position fixators, tips, etc.), only the workpieces for which the clamping sets were designed may be clamped in the intended manner using these clamping sets. If this is not observed, insufficient clamping forces or unfavourable clamping positions may result in material damage or personal injury. If further or similar workpieces are to be clamped with the same clamping set, written approval must therefore be obtained from the manufacturer.
4. Gripping force check Gripping force check (general) In accordance with standard EN 1550 § 6.2 No. d) for rotating work holding chucks which can also be applied to stationary clamping installations in this one point, static gripping force measuring instruments should be used to inspect the maintenance condition at regular intervals in accordance with the maintenance manual. This prescribes that a gripping force check should be performed after approx. 40 operating hours, irrespective of the clamping frequency. If necessary, special clamping force measuring jaws or instruments (load cells) must be used for this.

Safety Precautions and Guidelines for Use
3-jaw centric grippers
5. Strength of the workpiece to be clamped In order to ensure reliable gripping of the workpiece with the applied load forces, the clamped material must be strong enough to withstand the gripping force. Non-metallic materials such as plastic or rubber, etc. may only be clamped after testing and under particular observation!
6. Installation and adjustment work During clamping or alignment movements, etc., short distances are travelled in short times, in some cases with high forces. The drive system provided for the gripper actuation must therefore always be switched off during installation and adjustment work. If the clamping movements are essential during set-up mode, however, then for clamping strokes longer than 4 mm
- A fixed or temporarily installed workpiece holder must be installed on the device, or
- An independently actuated holding device must be installed, or
- A workpiece loading aid must be provided, or
- The set-up operations must be performed in hydraulic, pneumatic or electric jog mode (corresponding control must be possible!).
The type of this set-up aid depends fundamentally on the machine tool employed and may have to be procured separately!
The machine owner must ensure that during the whole clamping process, any danger to persons from the movements of the clamping means is ruled out. For this reason, either 2-hand controls for actuation of the clamping movement or - even better - corresponding guards must be provided.
7. Tightening and replacement of bolts If bolts are replaced or loosened, faulty replacement or tightening may result in dangers for persons and materials. For this reason, the tightening torque recommended by the bolt manufacturer and corresponding to the bolt grade must always be used for al mounting bolts unless expressly specified otherwise.
The following tightening torque table applies for all the standard sizes M5 - M24 for grades 8.8, 10.9 and 12.9:
If replacing the original bolts, always use bolt grade 12.9 in case of doubt. The grade 12.9 must always be used for the mounting bolts of clamping inserts, top jaws, fixed stops, cylinder covers and comparable elements. All mounting bolts which due to their intended use have to be frequently loosened and tightened again (e.g. due to tooling work) must be coated with lubricant (grease paste) every six months in the thread area and on the head contact surface.

Safety Precautions and Guidelines for Use
3-jaw centric grippers
III. Environmental hazards
A very wide variety of different media are currently required for lubrication, cooling, etc. during operation of a clamping or gripping installation. These are generally connected to the clamping installation by pipes or hoses. The most frequently used are hydraulic oil, lubricating oil/grease and coolants. Particular attention must be paid to these media when working with the clamping installation to ensure that they do not get into the ground or water. Caution! Environmental hazard! This applies in particular:
During installation/removal as there may still be residues in the pipework, piston chambers or oil drain plugs, To porous, defective or not correctly installed gaskets, To lubricants that for design reasons escape or are slung out of the clamping installation during operation.
These escaping substances should therefore be collected and recycled or disposed of in accordance with the applicable regulations.
IV. Safety engineering demands on power-actuated gripping installations:
1. The gripping installation may only be moved when the clamping pressure in the gripper has been built up and clamping can be carried out in the admissible working range.
2. Clamping may only be released when the gripping installation has come to a standstill.
3. In the event of a failure of the clamping energy, a signal must be given that immediately stops the machine.
4. In the event of a failure of the clamping energy, the workpiece must remain firmly clamped.
5. In the event of an electric power failure and return, it must not be possible for the momentary switching position to change.
V. Safety precautions:
1. Do not move parts by hand when the power supply is connected and switched on.
2. Do not reach into the open mechanical elements or between the clamping jaws.
3. Disconnect the energy supplies during installation, retooling, maintenance and adjustment operations.
4. Carry out maintenance, retooling or attachment outside the danger zone.
5. During installation, connection, adjustment, commissioning and testing, measures must be taken to ensure that accidental actuation of the unit by the fitter or other persons is not possible.
6. When using all handling modules, protective guards in accordance with the EC Machinery Directive must be fitted.
7.
Dangers are posed by objects falling or being slung out. Measures must be taken to prevent such falling or slinging out.
8. The service and maintenance intervals must be observed.
9.
Grippers which clamp under spring load or which have a gripping force lock with springs are under spring tension. The resilient pressing star is also under spring tension. Particular care is therefore necessary during dismantling.
10. Particularly on grippers with gripping force maintenance, top jaws must be designed such that in pressure-free state, a gripper reaches one of the end positions so that no residual energy is released during changing of the top jaws. In addition, the admissible active clearances from the corresponding tables must be observed. Furthermore, the safety and accident prevention regulations applicable at the place of operation must be observed.

Caution: The energy supply must be switched off during installation of the dirt cover on the gripper. Observe also the safety precautions. Please refer to the catalogue for the connection dimensions of the respective gripper size.
1) Before installing the dirt cover on the RZP gripper, the lower cover must be loosened and
removed from the gripper.
2) The connection surfaces must be clean and free from dirt.
3) Install the covers (item 62) on left and right on the end faces of the gripper and tighten
the mounting bolts slightly.
4) Now place the cover plate (item 61) into the gripper and bolt this with the hexagon head
bolts to the gripper and the side covers (item 62). Tighten all the mounting bolts.
5) Take the Quad-Ring supplied and place it into the groove of the cover plate.
6) Install the intermediate jaw on the base jaw. The intermediate jaw is centered on the
base jaw by means of the centering sleeves. Pay attention to the clearances of the wiper surfaces on the intermediate jaw – surfaces may have different lengths. The intermediate jaw must protrude by the same amount on both sides after positioning. When the gripper is open, the overhang corresponds to the jaw stroke of the gripper. Fasten the intermediate jaw to the base jaw using cylinder screw (item 68). After installing the intermediate jaws, check the free movement of the jaws.
7) Install the centering sleeves on the intermediate jaw.

Maintenance, Repair of Centric Grippers
3-jaw centric grippers
Maintenance and service life
The maintenance condition of the gripper is crucial for its function, clamping force, precision and service life.
The gripper is lubricated at the factory with a basic lubrication of special grease, ID 1096752 Klueberplex BEM 41-132.
We recommend Klueberplex BEM 41-132 for relubrication.
Service life with normal use without preventive maintenance: 5 million cycles Service life with normal use with preventive maintenance: 10 million cycles
Recommendation for preventive maintenance:
For normal use: Lubrication / cleaning: Every 2 million cycles or 1x per year
For heavy-duty use: Lubrication / cleaning: Every 1 million cycles or every 6 months with grease nipple
If no grease nipple is fitted, a grease nipple should be fitted to the purge port and the gripper lubricated here.
We recommend Klueberplex BEM 41-132 for relubrication.

Maintenance, Repair of Centric Grippers
3-jaw centric grippers
Dismantling and assembly of a gripper:
Caution: Be sure to observe the safety precautions.
1) Disconnect the pressure lines
2) Loosen the bolts and remove the cover, item 6 (RZP) or item 4 (RZP-A).
3) Unscrew the bolts and remove the flange, item 5
4)
Loosen the locating screw, item 8 (RZP) or item 12 (RZP-A) and remove the piston disc, item 4 (RZP) or item 6 (RZP-A). (The locating screw is secured with Loctite)
5) Press the wedge piston, item 3, up out of the gripper body, item 1.
6) Pull the base jaws (item 2) out of the gripper body (item 1).
7) Remove all gaskets
8) Clean all parts thoroughly and inspect the parts for wear or defects.
9) Renew all gaskets
The gripper is reassembled in the reverse order. Pay attention to the correct numbering and position of the components. Unless otherwise prescribed, all bolts must be secured with Loctite 222 and tightened to a torque as specified in the DIN standard (see point II/7).
Type GA or GI with gripping force lock:
Caution! Particular dangers exist here! Be sure to pay attention to the assembly drawing!
Gripper body, flange, piston disc and piston may be under spring pressure. The spring load on the piston disc (GA type) or flange (GI type) must be countered by appropriate means.

Maintenance, Repair of Centric Grippers
3-jaw centric grippers
Maintenance:
Extensive maintenance work only becomes necessary at fairly long intervals (approx. every 5 million gripping cycles). As soon as the gripper starts to bind and lose its gripping force, however, it must be removed from the machine and subjected to a general cleaning.
The gripper is thereby dismantled into its individual parts, inspected for wear, cleaned and after repairing any damaged parts reassembled and recoated with special grease. We recommend that the sealing elements subjected to dynamic loads, in particular, are replaced at this point. One set of the wear parts and sealing elements marked in the parts list should therefore always be in stock for this purpose.
During assembly of the gripper, pay careful attention that marked parts are installed in their correct positions again.
We should point out that only OEM spare parts or installation parts from authorised suppliers should be used. No warranty claims will be accepted for any damaged caused by the use of parts from third parties.
Note: For smooth ordering of spare parts or individual parts, always
quote the 6-digit identification number engraved on the component and – if possible – also the serial number. The serial number consists of a letter followed by 2 number and possibly a consecutive number stamped either on the rating plate or in the immediate vicinity of the identification number.
