SECTION 6 - MAINTENANCE AND TROUBLESHOOTING
When servicing the gate operator, always check any 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 entrapment protection devices (external and internal) when performing any maintenance. If any of these
devices 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 any entrapment protection devices are 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.
