Step-by-Step Repair Instructions

1. Safety First

Before you begin any repairs, unplug the can opener and make sure it’s completely cool.

2. Inspect the Cutting Wheel

Check the cutting wheel for any visible damage, such as bending or dullness. If the wheel is damaged, it will need to be replaced.

3. Clean the Cutting Wheel

Over time, food particles and grease can accumulate on the cutting wheel, causing it to become less effective. Use a cleaning brush to remove any debris.

4. Lubricate the Gears

Apply a few drops of lubricating oil to the gears. This will help reduce friction and prevent grinding noises.

5. Align the Cutting Wheel

If the cutting wheel is misaligned, it may not be able to cut cans properly. Adjust the wheel to ensure it makes contact with the can in the center.

6. Tighten Loose Screws

Loose screws can cause leaks or prevent the can opener from functioning properly. Use a screwdriver to tighten any loose screws.

7. Replace Worn-Out Parts

If the cutting wheel, gears, or gasket are worn out, they will need to be replaced. You can purchase replacement parts at most hardware stores or online.

Tips for Preventing Future Problems

• Clean your can opener regularly to prevent food debris and grease from accumulating.
• Avoid using the can opener on cans that are dented or damaged.
• Lubricate the gears occasionally to keep them running smoothly.
• If you notice any unusual noises or leaks, stop using the can opener immediately and troubleshoot the issue.
