Hand Release (7)
(Option dependent on Type for mechanical release of both
brake circuits individually using a Bowden cable or by
hand)
Danger!
Operate the hand release carefully.
Existing loads are put into motion when the
hand release is activated.
The hand release is completely assembled manufacturer-
side.
The brake is released when both hand release levers are moved
simultaneously (7.1), see Figs. 7 and 8.
By lifting the hand release levers (7.1) up from the steel balls
(7.2), both cap screws (7.4) incl. washers (7.6) together with the
armature disk (2) are pulled against the coil carrier (1) (Fig. 6).
The rotor (3) is then free, thus releasing the brake.

Noise Damping (Item 14 / Fig. 2)
The noise damping used here was set and adjusted
manufacturer-side. However, this component is subject to
