Page 9: Safety
Intended Use The centric clamp KZS-H/KZS-HG is used to clamp regularly and irregularly shaped workpieces. ▪ In the case of special workpiece geometries, corresponding top jaws must be used. -
Page 10: Improper Use
2 | Safety The centric clamp is a 2-jaw centric clamp. Only original RÖHM base jaws and top jaws may be used. Third-party makes may impair the safety of the centric clamp and lead to damage. The clamping point of the jaws must lie as close as possible to the centric clamp. -
Page 11: Obligations Of The Owner
Safety | 2 ▪ use of the centric clamp for suspending loads. ▪ operation outside of the defined operating parameters. ▪ operation with modifications not approved by the manufacturer. ▪ operation without effective safety equipment. ▪ assembly of the centric clamp and individual parts with incorrect tighten- ing torque (see Checking the Tightness of Screw Connections [} 36]). -
Page 12: Qualification Of Operating And Specialist Personnel
2 | Safety Qualification of Operating and Specialist Personnel Trained personnel Trained personnel have been instructed in correct handling and possible dangers when using the centric clamp. In particular, the personnel must have been instructed in the safety equipment. Qualified personnel Personnel without experience of handling a centric clamp are exposed to in- creased risks of injury in the event of incorrect conduct, especially during as- sembly and maintenance work, due to the clamping movements and forces. -
Page 13: Personal Protective Equipment And Personnel Qualification
Safety | 2 Personal Protective Equipment and Personnel Qualification When working on and with the centric clamp KZS-H/KZS-HG, personal pro- tective equipment must be worn. The owner is responsible for providing per- sonal protective equipment. ▪ Personal protective equipment must be in perfect condition when carrying out work. -
Page 14: Dangers Due To Flying Parts
Dangers due to Flying Parts During operation, the connection between the clamped workpiece and the centric clamp KZS-H/KZS-HG may become loose due to mechanical failure (e.g. due to defective parts) or incorrect operation. The workpiece may then fly out and cause serious crushing and impact injuries. -
Page 15: Danger Of Crushing
Safety | 2 2.6.4 Danger of Crushing The machine manufacturer and / or operator must ensure that all danger to persons due to unavoidable travel movements is excluded. For this purpose, 2-handed operation, for example, or preferably suitable safety guards can be used. -
