What You'll Learn
Locate the manual override
Electric roller shutters are convenient and enhance security and privacy, but sometimes you may need to open them manually in case of a power outage or a malfunctioning motor. Knowing how to do this is crucial for emergencies and maintenance. Most electric roller shutters feature a manual override mechanism, which is typically found on the motor or within the shutter casing. This can be in the form of a crank handle, a chain, a pull strap, or a winding rod.
The first step in opening an electric roller shutter manually is to locate the manual override. This is usually a small slot or hole near the motor or on the side of the shutter casing. If you cannot locate it, refer to your roller shutter's manual for exact instructions. If the manual override is a lever, simply turn it to disengage the motor and allow the shutter to be opened manually. If it is a keyhole, insert the provided manual override tool and turn it to disengage the motor.
The manual override tool could be a crank handle or a winding rod, which you would insert into the manual override slot or hole. If your roller shutter uses a crank handle, ensure you have it on hand. It should fit snugly and engage with the internal mechanism. If you cannot find the crank handle, it may be stored near the shutter. If your roller shutter uses a pull strap, it should be accessible near the bottom of the shutter or on the side.
Once you have located the manual override access point and the necessary tools, you can engage the mechanism. Turn the tool in the direction specified by the manufacturer's instructions, usually indicated in the manual or on the shutter casing. This action will engage the manual override mechanism, allowing you to manually raise or lower the shutter.

Use the correct tool
Electric roller shutters are heavy and complex systems, and attempting to adjust or repair them without the correct tools can be dangerous. If you're unsure about what you're doing, it's best to contact a professional roller shutter repair technician. They have the expertise and specialised tools to repair and maintain your roller shutters safely and effectively.
If you're confident in your ability to adjust your electric roller shutter, it's important to use the correct tools. Depending on the type of manual override system your roller shutter has, you may need specific tools. Consult your roller shutter's manual to identify the exact location and type of manual override mechanism for your model. The manual override can be a crank handle or a chain designed to enable manual operation when the electric system is unavailable. The crank handle is often stored near the shutter and provided by the manufacturer. If the manual override is a keyhole, you will need to insert the provided manual override tool and turn it to disengage the motor.
If your roller shutter is stuck, you can try to fix it by checking and cleaning the tracks. Use a soft brush or cloth to remove any debris. If the tracks are clean but the shutter is still sticking, you will need to lubricate them with a silicone-based lubricant. Be careful not to get any on the shutter's surface. You can adjust the tension by loosening the screws on the bottom bar and moving it up or down until the shutter operates smoothly.
If you need to open the shutter manually due to a malfunctioning motor, you can troubleshoot the issue once power is restored. Check the circuit breaker or fuse box to ensure the power supply to the motor hasn't been interrupted. If the motor still won't work, it may be a more serious issue that requires professional attention.

Engage the mechanism
Once you have located the manual override access point, it's time to engage the mechanism. This process will vary depending on the type of manual override system your roller shutter has. For example, if the manual override is a lever, you will simply need to turn it to disengage the motor. If your roller shutter uses a crank handle or winding rod, insert the tool into the manual override slot or hole and turn it in the direction specified by the manufacturer. This will engage the manual override mechanism, allowing you to manually raise or lower the shutter.
If your roller shutter uses a keyhole as the manual override, insert the provided tool and turn it to disengage the motor. Once the motor is disengaged, you can manually open the shutter by pulling it up or pushing it down, depending on the type of shutter. Remember that electric roller shutters can be heavy, so you may need assistance or a stable ladder to reach the shutter safely.
In some cases, the manual override mechanism may be located within the shutter casing. Consult your roller shutter's manual to identify the exact location and type of manual override mechanism for your specific model. Depending on the type of system, you may need specific tools such as a crank handle, which is often provided by the manufacturer and stored near the shutter.
It is important to note that attempting to repair electric roller shutters on your own can be dangerous. If you are not confident in your ability to troubleshoot and engage the mechanism, it is recommended to contact a professional roller shutter repair technician. They have the expertise and specialized tools to repair and maintain your roller shutters safely and effectively.

Adjust the speed
Adjusting the speed of your electric roller shutter can be done by setting the limits on the motor. This is a crucial step to ensure the shutter operates smoothly and efficiently, preventing damage and ensuring long-term functionality.
To adjust the speed, you must first turn off the power supply to the shutter for safety reasons. Then, using a screwdriver, remove the cover on the motor housing to access the limit switches. The lower limit switch controls how far the shutter descends. Use the adjustment tool provided to turn the limit switch in small increments. Turning it in one direction will extend the shutter's descent, while turning it the other way will shorten it. Test the shutter after each adjustment to see where it stops, and stop adjusting once the shutter closes to your desired position.
Once you are satisfied with the limit settings, replace the motor cover and secure it with the screws you removed earlier. You can then restore power to the shutter and test it again to ensure everything is working correctly.
If you notice a variation in the curtain speed, it may be necessary to change the spring or adjust the tension. Lack of tension is indicated by the roller shutter not being able to spring up or down. Adjusting the tension can be done by increasing it until the desired speed is achieved. If increasing the tension does not work, you may need to seek professional assistance.

Check for damage
If the shutter is still sticking, the tension may be too tight, which can be adjusted by loosening the screws on the bottom bar and moving it up or down until the shutter operates smoothly. Ensure that the area around the shutter is clear of any obstacles or hazards.
If the issue is with the motor, it could be due to incorrect placement within the shutter axle tube. Check that the motor drive wheel is inserted inside the axle tube and fixed securely with a screw or pop rivet. Over time, the wires and motor inside the shutter can deteriorate, and a replacement may be necessary.
If your roller shutter has a malfunctioning motor, check the circuit breaker or fuse box to ensure the power supply hasn't been interrupted. The motor may also stop working if it hasn't been installed properly or if there is a loose wire. If the motor is faulty or damaged, it's best to call a professional for assistance.
