Electric roller shutters provide convenience and security, but when there’s a power outage or an electrical failure, you may find yourself unable to operate them as usual. Knowing how to manually open a roller shutter without electricity is essential, especially in emergencies. Here’s a step-by-step guide to help you through the process.
Before attempting to manually open a roller shutter, it’s important to identify the type of system you have. Electric roller shutters typically come with a manual override mechanism designed for situations when there’s no power.
• Manual Override with Crank Handle: Most electric roller shutters have a manual override that allows you to operate the shutter using a crank handle.
• Manual Override with Pull Strap: Some shutters may use a pull strap mechanism instead of a crank handle.
Knowing which type of system you have will help you proceed with the correct method.
To manually operate the roller shutter, you’ll need to locate the manual override mechanism. This is usually found near the motor or on the shutter itself.
• Crank Handle Mechanism: Look for a small opening or slot, often located on the side or bottom of the shutter casing, where the crank handle can be inserted.
• Pull Strap Mechanism: If your shutter uses a pull strap, it should be accessible near the bottom of the shutter or on the side.
Step 3: Prepare Your Tools
If your roller shutter uses a crank handle, ensure you have it on hand. This tool is often provided with the shutter when it is installed. If you don’t have the original crank handle, you may need to purchase a replacement from the manufacturer or a hardware store.
For shutters with a crank handle mechanism:
1. Insert the Crank Handle: Insert the handle into the manual override slot. It should fit snugly and engage with the internal mechanism.
2. Turn the Handle: Slowly and steadily turn the handle in the direction indicated by the manufacturer. Typically, turning the handle clockwise will raise the shutter, while turning it counterclockwise will lower it.
3. Proceed with Caution: Take your time when turning the handle. Forcing it or turning too quickly can cause damage to the mechanism.
If your roller shutter is equipped with a pull strap mechanism:
1. Locate the Strap: Find the pull strap, which should be accessible near the bottom or side of the shutter.
2. Pull the Strap Gently: To raise the shutter, pull the strap downwards smoothly and steadily. To lower the shutter, let the strap retract slowly, controlling the speed with your hand.
3. Avoid Abrupt Movements: Sudden or forceful movements can cause the strap to slip or break, so proceed gently.
If the shutter does not move smoothly, there may be an obstruction in the tracks or an issue with the mechanism. Here’s what you can do:
• Inspect the Tracks: Check for any visible debris, dirt, or objects that might be blocking the shutter’s movement.
• Lubricate the Tracks: Use a silicone-based lubricant on the tracks to ensure smooth operation. Avoid oil-based lubricants, as they can attract more dirt.
Once you have opened or closed the shutter manually:
• Lock the Shutter: If your roller shutter has a locking mechanism, engage it to prevent unauthorised access.
• Check Stability: Ensure that the shutter is stable and properly aligned. If the manual override is only a temporary solution, consider scheduling a professional inspection to address any underlying electrical issues.
Knowing how to open a roller shutter without electricity is crucial for maintaining security and access during power outages or electrical failures. While many roller shutters are equipped with manual override mechanisms, the process can be challenging if you’re not familiar with it.
If you encounter any difficulties or are unsure about operating the manual override, it’s best to contact a professional. A skilled technician can not only help with manual operation but also inspect and repair any electrical issues, ensuring your roller shutters are fully functional and secure.
