6.1 Notes

Original spare parts

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

Exchange of housing and base jaws

The base jaws and the guidance in the housing are matched. To
exchange these parts, send the product with a repair order to
SCHUNK or order the housing with the base jaws as a set.

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.

Interval [Mio. cycles]
