Step PTO-3:
With the gate in the fully closed position and the opener retracted, swing the opener to the gate. Mark reference points for
bolt holes on gate cross member through middle of gate bracket slots. The opener must be level. (Some vertical adjustment is
possible by sliding the post bracket assembly up and down.) Drill
3 / 8 " holes into the gate cross member as marked. Fasten
gate bracket to cross member using (2) 3/8" x 3" bolts, washers, lock washers, and nuts. Attach the opener to the post bracket
assembly and gate bracket using clevis pins, washers, and hairpins clips.
Step PTO-7:
Repeat the procedure in step PTO-6 until the gate stops firmly
(but not sharply) against the open position stop plate. The
motor will continue to run for one-half second after the gate
opens 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!
NOTE: Each time you adjust the knob, finger tighten it before pressing the transmitter button to check your adjustment.
Step PTO-6:
To increase the degree of gate opening, loosen the
stroke adjustment knob on the bottom of the opener
housing and move it about
1 / 8 " toward the gate bracket
(see Fig. A). Finger tighten the knob–DO NOT USE
PLIERS OR OTHER TOOLS TO TIGHTEN KNOB.
Press the transmitter to check your adjustment. To
decrease the degree of gate opening, move the stroke
adjustment knob away from the gate bracket (see Fig B).

Step PTO-4:
Make sure the control box power switch is OFF. Use a small
screwdriver to move the PULL / PUSH DIP switch from the
factory setting to PUSH. Replace control box cover. Turn
power switch ON. The control board is now configured to push
the gate open.
Step PTO-5:
Press the transmitter to activate the opener and
determine the degree of gate opening. Initially, the
push-pull tube will extend only 7
1 / 2 " until it is adjusted
(see below right). The maximum extension of opener is
11
1 / 2 ".
