I. SETTING LIMIT CAMS
• Adjust the limit cams by loosening the clamp and rotating the cams. The cams
rotate with the swing arm shaft, so small adjustments are magnified by the length
of the gate.
• Use manual controls to move the gate during limit cam adjustment.
• To avoid damage to the gate and gate operator due to the gate overrunning its
limits, perform the following steps carefully:
1. SETTING RIGHT GATE LIMIT CAMS

barely closes the limit switch.

limit cams until they are set properly.
