4.4
Attachment of the EasyClamp
•
Carefully lay the EasyClamp around the glass and fold the
top and bottom segments together, closing them at their
open connection point.
•
Insert the bolt that does not have a spacer spring, and
tighten the knurled nuts slightly.
•
Tighten all knurled nuts uniformly by hand.
Note:
Always tighten the knurled nuts by hand and not to the block
(with the spring pressed together completely). Otherwise the
prestressing will be lost.
There must always be a gap of about 2 mm between the
knurled nut and the support surface.
4.5
Removal of the EasyClamp
On all EasyClamp connections,
only the bolt without a
spacer spring
has to be removed in order to open the con-
nection.
•
Release the knurled nuts on all (2 or 3) bolts until the springs
have been relieved. Do not, however, screw the nut all
the way off.
•
On the bolt that does not have a spacer spring, release
the knurled nut far enough (without removing it completely)
so that the bolt can be tilted out and removed as a unit.
•
At the connection point, which is now open, spread the
top and bottom segments apart and carefully remove the
EasyClamp.
