INSPECTION, MAINTENANCE, AND CLEANING
WARNING! Make sure the Circuit Breaker for the Gate Opener is in its “OFF” position
and that the fuse is pulled from within the Gate Opener Control Box before performing
any inspection, maintenance, or cleaning procedures.
1. Before each use, inspect the general condition of the Gate Opener hardware. Check
for loose screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, and any other condition that may affect its safe operation. If
abnormal noise or vibration occurs, have the problem corrected before further use. Do
not use damaged equipment.
2. Periodically recheck all nuts, bolts, and screws for tightness.
3. Periodically wash the Actuator Arm (A) stainless steel pistons with mild soap and water.
Do not oil the pistons.
4. Replace the Remote Control Battery every year as follows: Remove the two screws from
the back cover. Carefully open the cover. Remove the current battery. While following the
polarity markings on the plastic housing and the circuit board, install a new battery of the
same kind (“23A”). Carefully close the remote and secure. If the battery replacement is
done in a timely manner, the remote will store its codes in its memory. If not, reprogram
the remote according to the directions earlier in the manual.
