SECTION 5 – MAINTENANCE AND TROUBLESHOOTING
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.

5.1 Maintenance

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 SYNTHETIC SHC-629 oil. Do not completely fill gearbox with oil.
Gearbox should be half full only. Do not exceed this level. Synthetic oil MUST be used!
