Setting The Closed Gate Position
Step 17:
Carefully insert the power cable plug into the coupling at the
rear of the operator. Turn the plug until it aligns with the pins
in the coupling. Push the plug into the coupling until it stops.
Finger tighten the sleeve nut to lock the plug in position.
Replace the control box cover and fasten it with (4) screws.
Turn the control box power switch ON. The control board will
energize in approximately 15 seconds.

Stroke Adjustment Knob
Step 18:
Reattach front mount to gate bracket using clevis pin, washer, and hairpin clip. Press the transmitter to activate the
operator and see how far the gate closes. The push-pull tube will initially extend only 7
1
/
2
" until it is adjusted
(maximum extension of operator is 11
1
/
2
").
Step 19:
To increase the degree of gate closure, loosen the stroke
adjustment knob on the bottom of the operator housing
and move it about
1
/
8
" towards the gate bracket (Fig A).
Finger tighten the knob. (DO NOT USE PLIERS OR
OTHER TOOLS TO TIGHTEN KNOB) Press the
transmitter to check the closing distance. To decrease
the degree of gate closure, move the stroke adjustment
knob away from the gate bracket (Fig B).

Push-Pull Tube
Repeat the procedure in Step 19 until the gate closes firmly as the operator motor shuts down. Each time you adjust
the knob, finger tighten it before pressing the transmitter button to check your adjustment.
If the push-pull tube has been extended too far (i.e., if the knob is too close to the gate bracket), the gate will immediately
reverse and open after closing. When the knob setting is correct, the gate will close firmly, but not sharply, against
the positive stop plate. The motor will run for one-half second after the gate closes against the stop plate. If the motor
continues to run for more than one second, the push-pull tube is overextended and further adjustment is necessary. If
the motor strains too long against the stop plate, the fuse on the control board (above FIRST OPERATOR terminal)
will be blown. This blade-style 15 ampere fuse (sold by most automotive supply stores) can be easily replaced.
NEVER use a fuse rated higher than 15 amperes!
