7.1 Notes

Original spare parts

Use only original spare parts of SCHUNK when replacing spare and
wear parts.

Replacement of the housing and base jaws

The base jaws and the guides in the housing are matched to each
other. To replace these parts, send the product to SCHUNK with a
repair order.

7.2 Maintenance and lubrication intervals

CAUTION

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.
