4. Install Limit Ramps on Underside of Drive Rail

Push the gate to the fully closed position and drill two
⅜-inch holes through the drive rail to mount a 12-inch
plastic limit ramp under the drive rail.

Locate drive rail so that it will trip the limit switch
approximately 6-inches before the exact spot you want the
gate to stop.

Adjust the ramp left or right to achieve exact stopping point.

Fully secure by tightening both bolts.

Adjust the lever arms on the limit switch so that the roller
clears the underside of the drive rail by at least ¼-inch.

Push the gate fully open and repeat this procedure with the
other limit ramp.

Refer to the drive rail drawing S22 on page 17.
5. Clamp the Drive Wheels to the Drive Rail
When the wheels are fully clamped on the drive rail, the
red spring should be compressed to 2-inch in height. If
adjustment is necessary, turn the nut at the bottom of the
threaded rod assembly. Slightly less compression is okay
for lighter gates. See Section 8
— Use and Adjustment of
the Manual Release Mechanism on page 54.
