7.3 Gate Operator’s Monthly Checkup
Caution: Make SURE gate area is clear BEFORE testing the gate operator!
DO NOT repair or adjust gate systems yourself. Contact a trained gate systems technician with any questions
or to make any repairs or adjustments. If you feel uncomfortable performing any of these inspections or testing,
a qualified service technician will perform the visual inspections and testing for you.
You can find a trained service technician at DoorKing’s “Dealer Locator” at www.doorking.com
Test Built-In Reversing Sensor
Begin with the gate in the fully OPEN position. Stand just outside the path of the gate and close the gate (typically auto-timer
will time-out and close gate automatically). As the gate is closing, firmly press a solid object against the end of the gate
frame in the direction opposing the travel of the gate. The gate should stop within 2 sec. and reverse to the OPEN position.
Another input command is needed before the gate will reset and close again. Repeat this test while opening the gate. Start
from the fully CLOSED position. While opening, gate should stop and reverse to the CLOSE position. If gate does NOT
respond like it should in either direction of gate travel, contact a trained service technician to make adjustments or repairs.
Test Photo Sensors
If the gate has a photo sensing device protecting the path of a closing gate, perform the following test. Begin with the gate in
the fully OPEN position. Stand just outside the path of the gate and close the gate (typically auto-timer will time-out and close
gate automatically). Pass an object across the path of the closing photo sensing beam. The gate should stop within 2 sec.
and reverse to the OPEN position. Typically the auto-timer times out and gate closes again.
If the gate has a photo sensing device protecting the path of a opening gate, start from the fully CLOSED position. OPEN
gate. Pass an object across the path of the opening photo sensing beam. The gate should stop, the gate will resume opening
when the beam is clear. If gate does NOT respond like it should in either direction of gate travel, contact a trained service
technician to make adjustments or repairs.
Test Reversing Edges
If the gate has a reversing edge(s) protecting the path of a closing gate, perform the following test. Begin with the gate in the
fully OPEN position. Stand just outside the path of the gate and close the gate. As the gate is closing, firmly press a solid
object against the reversing edge in the direction opposing the travel of the gate. The gate should stop within 2 sec. and
reverse to the OPEN position (typically auto-timer will time-out and close gate automatically). If the gate encounters another
obstruction before it is closed, the gate will stop and reverse to the OPEN position again. A input command is needed before
the gate will reset and close again, auto-timer will NOT close gate (Typically, press your remote button for input command).
If the gate has a reversing edge(s) protecting the path of a opening gate, starting from the fully CLOSED position.
Stand just outside the path of the gate and open the gate. OPEN gate. As the gate is opening, firmly press a solid object
against the reversing edge in the direction opposing the travel of the gate. gate should stop and reverse to the CLOSE
position. If gate does NOT respond like it should in either direction of gate travel, contact a trained service technician to make
adjustments or repairs.
Visual Inspection
Visually inspect the rollers, fasteners, brackets and other gate hardware for proper alignment, proper tightness, and signs of
damage, breakage, looseness, rust or wear. Moving parts should be lubricated and should not be squeaking.
Visually inspect wiring for fraying or exposure. If a malfunction is found, contact a trained service technician to make
adjustments or repairs.
Note: This gate operator uses high levels of force to move the gate and most people underestimate the power of these
systems and do not realize the potential hazards associated with this system if NOT maintained properly.
Scheduled maintenance visits are offered by most qualified service technicians to MAINTAIN your gate operator system.
