Precautions for rear release button
1. The release button is a safety measure for emergency evacuation when operator is accidentally trapped in the safety fence(hazard area).
2. Rotate the metal knob 90° anticlockwise to release safety door switch and open the door.
3. After removed danger, please rotate the metal knob 90° clockwise to restore the locked state. The door cannot be locked evenif the door is closed when the release knob is in the unlocked position.
4. Be sure to install the emergency release knob in an operable place inside safety fence (hazardous area).
5. Please do not operate the emergency release knob with tools or apply excessive force or force in directions other than theoperating direction, or beyond the knob rotation angle range, so as to avoid damage to the knob parts and cause failure.

Brackets Size
Loosen 4 screw on top of head, rotate thehead to the right key inserting position andthen install it.
When install on side hung door, it should be over than semidiameter
Please install the safety switch door and insertion key under range 1-3.5mm
The installation of operation key allows ±1mm deviation within the key insertion center of the hole.
