16 Maintenance and Care 8.4 Maintenance Servicing and assembling the module Clean all parts thoroughly and check for damage and wear. Treat all greased areas with lubricant. Link Schmierstoffe/Schmierstellen Oil or grease bare external steel parts. Replace all wear parts / seals. Position of the wearing parts ( 9, Page 19) Sealing kit ( 10, Page 21) Assembly Assembly takes place in the opposite order to disassembly. Observe the following: Unless otherwise specified, secure all screws and nuts with Loctite no. 243 and tighten with the appropriate tightening torque.link Anzugsmoment für Schrauben Make sure the individual components are clean for the assembly. No foreign substances must adhere to the parts. This also applies when mounting the gripper to an adapter plate provided by the customer and when flanging top jaws provided by the customer onto the gripping fingers. Clean and disinfect the gripper each time after maintenance SG 47 en

17 Maintenance and Care 8.5 Daily cleaning in the food industry Faultless continuous operation can only be ensured if the SG 47 gripper is constantly kept clean with impeccable hygiene. The gripper should usually be disinfected each time before cleaning (see cleaning agent recommendation in the appendix). Disinfectants must not come into contact with food, neither directly nor indirectly. Flush the device therefore with clear water after disinfecting it. NOTICE Do not add any aggressive solvents! 8.6 Cleaning the gripper in the food industry Clean the gripper with a cloth and warm water after using it. Stubborn or encrusted dirt must be soaked. Drying residues should be avoided. Dry residues prolong the cleaning measures or make them more difficult. To prevent material damage, only approved products may be used. Water hardness layers are to be removed as soon as possible. For this purpose, distribute a cleaning agent, if possible as foam, on the surface to be cleaned. Then remove the loosened dirt with warm water. Make sure you flush thoroughly after cleaning (see cleaning agent recommendation in the appendix). We recommend using low-pressure foam systems (< = 25 bar). Low pressure also prevents the development of aerosols and therefore recontamination of cleaned surfaces SG 47 en 17

18 Maintenance and Care 8.7 Recommended cleaning agents for the food industry NOTE A cleaning plan and other details can be found in the appendix. The cleaning agent manufacturers in the appendix are responsible for the chemical composition and function of their cleaning agents. The cleaning agents are only recommendations; the material compatibility and hygiene regulations must be checked by the customer if other cleaning agents are used. 8.8 Recommended types of lubricating grease for the food industry All individual components moved in the gripper are greased with a synthetic lubricant, Klübersynth UH Klübersynth UH has been developed for the special demands on lubricating grease of the food and pharmaceutical industry. It fulfills the provisions of the German Food and Consumer Goods Act (LFBG, 5 paragraph 1, 31 paragraph 1), as well as DIN V "Food- Processing Lubricants" and meets the American requirements "Guidelines of sec. 21 CRF of FDA regulations". Quality: H1 approval; the manufacturer is responsible for the correct material composition, function and certification of the lubricating grease. 8.9 Maintenance in the food industry The SG 47 gripper is designed for a long life. However, if it still needs repair, please contact our service department or our head office directly SG 47 en
