8.1 Notes

DANGER

Danger of explosion in potentially explosive areas!

•

Observe supplementary sheet for products with explosion-
resistant versions "SRU-plus -...-EX".

Original spare parts

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

8.2 Maintenance interval

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.
