- Using the Wall Control: Press the wall control button once to open or close the garage door. Pressing it again during motion will stop the door.
5.2. Manual Override (Emergency Release)
In case of a power outage or malfunction, you can manually operate the garage door:
- Ensure the garage door is fully closed if possible.
- Pull the red emergency release handle firmly downwards. This disengages the door from the opener.
- You can now manually open or close the garage door.
- To re-engage, pull the red handle towards the opener until it clicks into place. Operate the opener once to ensure it is properly re-engaged.
CAUTION: Do not use the emergency release unless the garage door is closed. If the door is open, it may fall rapidly.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your garage door opener. Always disconnect power before performing any maintenance.
6.1. Monthly Checks
- Safety Reversal Test: Place a 1.5-inch (4 cm) object on the floor in the door's path. The door must reverse upon contact. If not, adjust the force settings or contact service.
- Door Balance: Disengage the opener using the emergency release. Manually open the door halfway. It should stay in place. If it drifts up or down, the door springs are unbalanced and require professional adjustment.
- Hardware Inspection: Check all hinges, rollers, cables, and springs for wear, rust, or damage.
6.2. Annual Maintenance
- Lubrication: Apply a silicone-based lubricant to the rollers, hinges, and springs. Do not lubricate the opener rail unless specified by the manufacturer.
