Makita DGA458 Problems and Solutions
some common issues and problems with the Makita DGA458 angle grinder, along with step-by-step solutions from experts:
Issue: The angle grinder is not spinning at a constant speed or is slower than normal.
Solution: This is most likely due to worn carbon brushes. The carbon brushes are two pieces of an electric motor that transmit current to the rotating armature via the commutator. Worn carbon brushes can decrease the overall performance of the motor, and can even cause the motor to overheat.
To replace the carbon brushes, you will need to disassemble the angle grinder. Once the grinder is disassembled, you will need to locate the carbon brushes. They are usually located near the commutator, which is the round metal disc with copper segments.
Once you have located the carbon brushes, you will need to remove them. There are usually two screws that hold each carbon brush in place. Once the screws are removed, you can carefully pull the carbon brushes out of the grinder.
To install the new carbon brushes, simply reverse the steps above. Make sure that the new carbon brushes are properly aligned with the commutator. Once the new carbon brushes are installed, reassemble the angle grinder and test it to make sure that it is working properly.
Issue: The angle grinder is not starting.
Solution: This is most likely due to a faulty switch. The switch is responsible for turning the grinder on and off. If the switch is faulty, it will not be able to properly connect the power to the motor, and the grinder will not start.
To test the switch, you will need to use a multimeter. Set the multimeter to the continuity setting and touch the leads of the multimeter to the two terminals of the switch. If the switch is working properly, the multimeter should beep. If the multimeter does not beep, then the switch is faulty and will need to be replaced.
To replace the switch, you will need to disassemble the angle grinder. Once the grinder is disassembled, you will need to locate the switch. It is usually located near the handle of the grinder.
Once you have located the switch, you will need to remove it. There are usually two screws that hold the switch in place. Once the screws are removed, you can carefully pull the switch out of the grinder.
To install the new switch, simply reverse the steps above. Make sure that the new switch is properly aligned with the terminals. Once the new switch is installed, reassemble the angle grinder and test it to make sure that it is working properly.
Issue: The angle grinder is overheating.
Solution: This is most likely due to a dirty or clogged air filter. The air filter helps to keep the motor cool by preventing dust and debris from entering the motor. If the air filter is dirty or clogged, it will not be able to do its job properly, and the motor will overheat.
To clean the air filter, you will need to remove it from the grinder. Once the air filter is removed, you can clean it with a vacuum cleaner or compressed air. Once the air filter is clean, you can reinstall it in the grinder.
If the air filter is too badly damaged to be cleaned, you will need to replace it. To replace the air filter, you will need to purchase a new air filter that is compatible with your model of angle grinder.
Issue: The angle grinder is smoking.
Solution: This is most likely due to a bearing that is failing. The bearings in the angle grinder help to keep the motor and gears rotating smoothly. If a bearing is failing, it will start to make noise and smoke.
If the angle grinder is smoking, you should immediately stop using it and have it repaired by a qualified technician. Continuing to use the grinder could damage the motor and gears, and could even cause a fire.
