SECTION 7 - MAINTENANCE AND TROUBLESHOOTING
When servicing the gate operator, always check any secondary
(external) reversing devices (loops, photocells, etc.) for proper
operation. If external reversing devices cannot be made operable,
do not place this operator in service until the malfunction can be
identified and corrected.
Always check the inherent reversing system when performing any
maintenance. If the inherent reversing system cannot be made
operable, remove this operator from service until the cause of the
malfunction is identified and corrected. Keeping this operator in
service when the inherent reversing system is malfunctioning
creates a hazard for persons which can result in serious injury or
death should they become entrapped in the gate.
When servicing this gate operator, always turn power
OFF!!
