4 Putting into Operation
4.5 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.
4.6 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 comple-
tely) 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.
