Do you have a bench grinder that needs repair? In many cases your bench grinder only needs simple maintenance and cleaning to function properly. Before you contact a professional repair your bench grinder, read these simple steps that can help you repair it yourself. First, note down and prepare the tools and materials you will need.

Step 1 – Unplug your Bench Grinder

Before you work on trying to repair your bench grinder, make sure it is completely shut off. The grinder should also be unplugged to avoid any instance of accidentally pressing the "on" switch. Put on your goggles and gloves for protection.

Step 2 – Remove Debris

Over the days, months or years that you've been using the bench grinder, you will see the build-up of dust, sparks and debris. Whenever you polish or grind objects with your bench grinder, the debris, sparks and dust collect on the safety shield covers that comes with the grinder at purchase. If you don't periodically clean the cover and remove the dust and debris, there's a big chance that your grinder and polisher wheels will get stuck. That's why you have to regularly clean it. Get the chisel and position its head against the debris and the piles of metal sparks that you find around the inner lip of your safety shield. Swing the hammer against the chisel to start taking out the chunks of debris that has built up. Do the same on each side of the bench grinder wheels.

Step 3 – Finish Cleaning

After all the sparks and debris build-up have been removed, take your small wire brush and clean each wheel. Brush around the wheel until you've cleaned the whole thing. It might help to use a vacuum to get rid of the small debris.

Step 4 – Test out your Bench Grinder

Now that it's clean and debris that might have caused your grinder to stock up is removed, it's time to test it out. Plug your bench grinder and switch it on to see if it's working. If it is, great job. All you needed to do was to remove the debris that's been keeping it from turning on. However, if it still doesn't work, perhaps it's time to check the parts of your bench grinder.

Step 5 – Inspect the Bench Grinder Parts

Inspect each part of the bench grinder and see it anything needs replacement. Always make sure to locate the model number of your bench grinder and refer to your manual. In case you've lost your manual, you can try searching for one either online or by ordering through the manufacturer. That's why you will need to note down the model number. You can find it on a plate attached to the housing of the bench grinder's motor.
