6 Maintenance
6.1 Notes
Original spare parts
Use only original spare parts of SCHUNK when replacing spare and
wear parts.
It is of advantage to have maintenance performed and the seals
replaced at SCHUNK. If this is not possible, you can perform the
maintenance and replace the seals yourself.
To replace parts, send the complete gripper with a repair order to
SCHUNK.
In the case of the PWG-S 80, the piston and body must be aligned
and mounted with a device during the assembly.

6.2 Maintenance interval
NOTICE
Material damage due to hardening lubricants!
Lubricants harden more quickly at temperatures above 60°C,
leading to possible product damage.
• Reduce the lubricant intervals accordingly.
