Manual Release Adjustment
Caution: Load to be removed or blocked. Brake will be
inoperative during this procedure.

brake is released;
b) The release knob returns to its normal position
automatically when power is applied to the magnet.
NOTE: Adapter housing (7) must be removed to make this
adjustment.

position automatically, turn screw (17) clockwise 1/4 turn
and try again.
NOTE: You may have to repeat Steps 2 or 3 to get
the release to operate properly.
It is important that the release knob returns to its
