Maintenance
1. Check the door at least twice a year if it is properly balanced and all working parts are in good working
condition or not.
2. Check the reversing sensitivity at least twice a year, and adjust if it is necessary.
3. Make sure that the safety devices are working effectively (photo beams, etc.)
4. Light bulb replacing:

of the new light bulb is in accordance with the local voltage and the power is within 25 Watt. Demount the
screws on the lamp cover. Take the lamp cover away then twist off the old light bulbs anti-clockwise. Fix the
new lamp bulb and lamp cover.

will void the warranty.
