Once the clamp has been adjusted to the desired force depending on the minimum
work pressure the non-reversibility should be checked according to the point
(5.3 Self-Iocking).
5.3 Self-locking
After the desired clamping force has been set in accordance with the minimum working
pressure (Table „Operating pressure"), check the self-locking mechanism of the clamp.
Checking the bearing gap:
· Remove side bearing cover on the
clamp
· If the clamping arm position (0°) is
reached, self-locking acts if
A = 0,5 mm

Maintenance
The clamps are fitted with low maintenance bearings and guides for use in large batch
production. It is nonetheless necessary to protect the clamp from dirt and pollution. The
maintenance interval depends on the ambient conditions and the frequency of use.
6.1 Cleaning
·
Remove cover
·
Blow out clamp from both sides
·
Spray mechanisms with a lubricant suitable for needle bearings
·
Re-attach cover
Cleaning the unit with a high-pressure cleaner, dry ice or similar
can damage the clamp!
If used under extreme ambient conditions (welding spatter, etching, high temperatures,
etc.), in particular during arc welding, the clamp must be coated with a special agent
(fluropolymer).
The power clamps GN 865 / GN 866 are not suitable for use in arc welding.
6.2 Compressed air
·
We advise using conditioned (filtered) compressed air to prevent particles such as
dust, oil or others damaging the inner components of the power clamps.
·
If a compressed air system with oil lubrication is used, the oil must be mineral-based
or synthetic to avoid incompatibility with the grease of the seals.
6.3 Grease for seals
·
The commercial grease AR 34-402 is used in all standard power clamps.
For special-purpose designs and for high temperatures, Barrierta L55/1
is recommended. Both greases are brands of Klüber Lubrication. If you have any
further questions, please contact the manufacturer directly.

Close the power clamp
with pressure or by hand until it
reaches the top position.
Bring both screws on the mobile arm
over to the sheet until they contact it
without pressure.
Open the clamp with pressure or by
hand until it gets the position of rest.
Turn the screws and adjust them
according to H or turn screws figures.
