SECTION 7 - MAINTENANCE AND TROUBLESHOOTING
When servicing the gate operator, always check any secondary (external) reversing devices (loops, photo eyes, 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!!
If gearbox requires oil, use only Mobil SYNTHETIC SHC-629 Oil. Do not completely fill gearbox with oil. Gearbox should
be half full only. Do not exceed this level.
Inspection and service of this gate operator by a qualified technician should be performed anytime a malfunction is observed or
suspected. High cycle usage may require more frequent service checks.
