In principle, the jaw boxes do not require any special maintenance
beyond the usual care for clamping devices.
Depending on the type of stress, the clamping device should be
serviced at certain intervals

cleaning the jaw boxes regularly and lubricating the stressed parts
and guides with special grease LINO MAX.
For lubrication, the jaw box is equipped with a grease nipple
(item 15) for manual lubrication. For complete cleaning,
disassemble and clean the jaw box.

When replacing spare parts or cleaning, the jaw box will have to be
