Step 17
Carefully insert the power cable
plug into the coupling at the
rear of the opener. 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.
Setting the Closed Position
Step 18
Reattach the front mountof the opener arm to gate bracket using a clevis pin, washer, and hairpin clip. Press the transmitter
button to activate the opener and determine the degree of gate closure. Initially, the push-pull tube will extend only 7" to 8"
until the stroke adjustment knob is set (see below right). The maximum extension of the push-pull tube is 11
1 / 2 ".
Step 19
To increase the degree of gate closure, loosen the
stroke adjustment knob on the bottom of the
opener housing and move it approximately
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 button to check your adjustment. To
decrease the degree of gate closure, move the stroke
adjustment knob away from the gate bracket (see
Fig. B).
Step 20
Repeat the procedure in Step 19 until the gate closes firmly as the opener 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!
