al release page 5).
3. Remove the 2 screws on the sides of the cover (see picture 7).

5.5 Gate Rack Mounting

1. Manually move the gate into CLOSED position.
2. The steel or nylon rack can be attached by welding (steel only) or with screws (see picture 9). Put the first rack segment at the end of the gate so that it connects to the
operator sprocket as shown in the picture 10 and attach the rack to the gate. Then move the gate and attach the next rack segment near to the previous segment.
Proceed this way until you will reach complete OPEN position.
NOTE: At all times consider that the rack does not complietly lie on the operator sprocket or has too much distance to it.
Before assembly:
• Check whether the required screw-in depth available.
• Use the supplied connecting elements (screws) to assemble
the racks.
• Attach the rack segment at the right position by using the
delivered screws.
NOTE:
The material type and thickness at the mounting position of the
rack must be considered. The operator must be disengaged.
