ACCESS CONTROL SOLUTIONS . . . 34 Preventative Maintenance Guide
• When servicing, place AC power switch to the OFF position. If the operator is equipped with a
battery back-up system, place the battery power switch to the OFF position.
• Inspection and service should be performed anytime a malfunction is observed or suspected.
High cycle usage may require more frequent service checks.
• Use only Shell OMALA 150 gear oil when adding or replacing gearbox oil. IMPORTANT:
Do not fill gearbox to top. Gearbox is full when oil completely covers inspection
window.
Always check external reversing devices (loops, photo-cells, etc.) when performing maintenance. If
reversing devices are not functional and cannot be placed in an operable state, DO NOT PLACE
OPERATOR IN SERVICE. If the operator is equipped with a battery back-up system, follow the steps
below to check the operation of this system.
CAUTION: Keep clear of the arm and all internal moving parts.
1. Prior to checking the battery back-up system, both the AC power switch and the battery
back-up switch should be in the ON position.
2. Place the AC power switch to the OFF position. The arm should rotate to the UP position
approximately two seconds after the AC power switch is shut off.
3. Turn the AC power switch to the ON position. The operator will resume normal operation.
