Disassembling the Angle Grinder
If you want to learn how to repair an angle grinder, one of the first things you need to know is how to disassemble it. This can seem daunting at first, but with the right approach and tools, it’s actually a fairly straightforward process. Start by unplugging the grinder and removing the blade guard, then using a wrench to loosen and remove the locking nut holding the blade in place.
From there, you can remove the blade and inspect it for damage or wear. You can also disassemble other parts of the grinder, such as the motor or gearbox, to diagnose and fix issues. However, it’s important to be very careful when working with these components, as they can be quite heavy and potentially dangerous.
With a bit of patience and care, though, you can take your angle grinder apart and start repairing it like a pro.
Removing the Disc and Guard
Removing the disc and guard is an essential part of disassembling an angle grinder. It is important to note that you should always unplug the grinder before attempting to disassemble it. Start by removing the disc from the spindle.
To do this, find the spindle lock button located on the side of the grinder, and hold it down while using a wrench to turn the disc counterclockwise. Once the disc is loose, you can remove it from the spindle. Next, you will need to remove the guard, which is the safety cover that surrounds the disc.
The guard is typically held in place with several screws or bolts. Locate these fasteners and use a screwdriver or wrench to remove them. Once all the fasteners are removed, carefully lift the guard off of the angle grinder.
Be sure to take note of how the guard was attached so you can easily reinstall it later. With the disc and guard removed, you can now proceed with further disassembly or maintenance on your angle grinder.
Getting to the Motor
To get to the motor of your angle grinder, you’ll need to take it apart. But don’t worry, it’s not as difficult as it may seem. First, unplug the grinder and remove the disc.
Then, use a screwdriver to loosen the screws holding the outer casing in place. Once removed, you should be able to see the motor and gears. If you’re having trouble getting to the motor, refer to your grinder’s manual for specific instructions.
It’s important to note that if you’re not comfortable taking apart your grinder, it’s best to leave it to a professional. This way, you can ensure that your grinder is properly disassembled and reassembled without causing any damage. With a little patience and caution, accessing the motor of your angle grinder is a breeze.
So, go ahead and give it a try for yourself!
Repairing the Angle Grinder
If you’re a DIY enthusiast, you’ve probably used an angle grinder before. These powerful tools are great for grinding, cutting, and polishing metal and other materials. However, like any tool, angle grinders can break down and need repair.
So, how to repair angle grinder? First, check to see if the problem is a simple fix, like a loose bolt or frayed cord. If so, tighten the bolt or replace the cord. If the problem is more serious, such as a burned-out motor or broken gearbox, it may be time to replace the angle grinder altogether.
To prevent future breakdowns, be sure to clean and lubricate your angle grinder regularly, and always use the correct attachments and grinding wheels for the job at hand. By taking care of your angle grinder, you can ensure that it will last for years to come.
Replacing Faulty Components
If your angle grinder starts acting up, then you may need to replace some faulty components. One of the most common issues with angle grinders is a malfunctioning switch. If the switch isn’t working properly, then your grinder may not turn on or off correctly.
To fix this problem, you’ll need to take the grinder apart and replace the switch. Another issue you may encounter is a worn-out or damaged grinding wheel. If this is the case, then you’ll need to replace the wheel before you can use your grinder again.

Putting everything back together after disassembling an angle grinder can be a daunting task. The first step is to refer back to your disassembly guide and make sure you have all the parts and tools needed. Once verified, start by putting the armature back in place, followed by the bearings.
Secure the armature with the top retaining screw. Next, fit the field coils in place and put back the brush holders. You can now insert the brushes carefully, one at a time.
Make sure they slide smoothly into the brush holder and contact the armature surface for proper electrical conductivity. Replace the cord and reassemble the handle. Finally, put the guard back in its place to protect against debris.
A properly reassembled angle grinder should run smoothly without any issues. Happy grinding!
