6.1 Maintenance

SECTION 6 - 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.

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.
