Push Arm Installation (Cont.)
Pull Arm Installation
1. Install the slide track assembly at the pull side of the door at the proper location from the hinge end of
the door as shown below:
2. To install the pull arm, the operator must be powered to the full open position, as it is not possible to
install the arm in the closed position as to allow proper preload.
3. Power the door to the open position through the use of the hold-open switch on the side of the header.
It may be necessary to first execute a “setup” on the operator prior to doing this. See page 11 for
commissioning instructions.
4. Once the operator is rotated to the full open position, manually move the door to the desired full open
position and insert the slide track guide block into the track. When completed, the end caps to the track
can be installed.
