CONTROL ARM ASSEMBLY (SW470)

1.Set the control arm stop on the operator in the positions appropriate for the installation (Figure 1).

2.Install the arm channel to the hub assembly to the operator output shaft.

3.Secure the arm channel to arm hub with 1/4-20 black plastic knobs provided (Hub is factory installed - Figure 2).

4.Assemble extension arm to control arm. Be sure to keep the extension arm with spot-faced side up. Use the holes that are appropriate for desired degree of gate opening. The extension arm should swivel easily on pivot screws when the nuts are tightened. Attach the other end of the actuator arm to the gate brackets (Figure 3).

CAUTION

If the arm stop is installed incorrectly, the gate will be prevented from opening and damage to the operator may result!

1.Install gate bracket (supplied) or install an angle (2" x 2" x 1/4" by others) horizontally on gate, at the same height as the top surface of the control arm extension (see figure to the right).

2.Adjust the eccentric stop as shown so that the wide area of the eccentric stop is against the arm. Be sure that the control arm and actuator are in a straight line. Install the gate bracket and if required install an angle (for SW490 2" x 2" x 1/4" by others) at the appropriate point on the gate in reference to gate hinge pin.

NOTE: As an alternative, (2) 3/8-16 bolts and a nut plate are provided. Adjust arm length and then rotate the eccentric stop 180 degrees so that the small thickness is against the arm. This will provide the necessary deflection in the arm assembly to lock the gate.
