9 Maintenance and Repair

9.1 General notes

The rotary grippers are almost maintenance-free. Nevertheless, some

maintenance work must be carried out to ensure an optimum operating

condition of the rotary grippers.

Each rotary gripper is accompanied by a safety information sheet. This

information sheet must be read carefully by every person who carries out

work on and with the rotary gripper.

9.2 Safety instructions for maintenance and repair

Also observe the safety instructions in



Chapter 2 „Safety instructions“ in

this manual.

WARNING

Danger of injury due to improper maintenance!

Improperly carried out maintenance activities can cause considerable

damage to property and serious injury.



The operator must exercise due care and only use trained maintenance

personnel to carry out the activities.



Always wear personal protective equipment when carrying out maintenance

and repair work!

WARNING

Risk of injury due to uncontrolled movements of the rotary grippers!

Signals from the control system can trigger unintentional movements of the

rotary grippers, which can cause injury.



Before starting any work on the rotary grippers, switch off the control unit

and secure it from being switched on again. Observe the operating

instructions of the controller used!



Before starting any activities, switch off the media supply (pneumatics) and

secure it from being switched on again!
