Makita DGA454 Problems and Solutions

some common issues and problems with the Makita DGA454 angle grinder and their solutions:

• The angle grinder is not spinning at a constant speed or is slower than normal.
  • This is most likely caused by worn carbon brushes. To check the carbon brushes, first unplug the angle grinder and remove the side cover. The carbon brushes are located inside the motor housing. If the carbon brushes are worn down to the point where they are no longer making contact with the commutator, they will need to be replaced.
  • To replace the carbon brushes, follow these steps:
    • Remove the old carbon brushes by gently prying them out of the motor housing.
    • Insert the new carbon brushes into the motor housing, making sure that they are properly seated.
    • Replace the side cover and plug in the angle grinder.
• The angle grinder is smoking.
  • This is most likely caused by overheating. The angle grinder can overheat if it is used for too long at a high speed, or if it is used in a dusty environment. To prevent the angle grinder from overheating, take breaks every 15-20 minutes to let it cool down. If you are using the angle grinder in a dusty environment, use a dust mask to protect the motor from dust.
  • If the angle grinder is still smoking after taking these precautions, it may need to be serviced by a qualified technician.
• The angle grinder is making a loud noise.
  • This is most likely caused by worn bearings. The bearings in the angle grinder help to reduce friction and keep the motor running smoothly. If the bearings are worn, they can cause the angle grinder to make a loud noise.
  • To check the bearings, first unplug the angle grinder and remove the side cover. The bearings are located inside the motor housing. If the bearings are worn, they will be noisy and may have visible signs of wear, such as cracks or rust.
  • If the bearings are worn, they will need to be replaced. To replace the bearings, follow these steps:
    • Remove the old bearings by gently prying them out of the motor housing.
    • Insert the new bearings into the motor housing, making sure that they are properly seated.
    • Replace the side cover and plug in the angle grinder.

If you are unable to fix the problem yourself, you may need to contact Makita customer service for assistance.

Safety Information

• Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
• Save all warnings and instructions for future reference.
• The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. Work area safety

• Keep work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away from work area. Distractions can cause you to lose control of the power tool.

2. Electrical safety

• Use an extension cord that is in good condition and is the correct size for the power tool you are using. An undersized extension cord will cause a drop in voltage, resulting in reduced power and overheating.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

3. Personal safety

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating a power tool may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection when operating a power tool. Safety glasses with side shields are recommended for most applications. Dust mask, non-slip safety shoes, hard hat, hearing protection and gloves may also be required depending on the type of work being performed.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothing, jewelry or long hair can be caught in moving parts and result in serious personal injury.
• Use the right tool for the job. Do not force a power tool to do a job it was not designed to do. Use the right size power tool for the size of the workpiece.
• Do not overreach. Keep proper footing and balance at all times. This will enable better control of the power tool in unexpected situations.
• Use auxiliary handles, if provided, to maintain control of the power tool in unexpected situations.
• Use a non-skid mat or workshop floor to prevent slipping and accidental falling.

4. Power tool use and care

• Do not force the power tool. It will work better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off properly. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the power tool. This will prevent accidental starting of the power tool.
• Store power tools out of the reach of children and other untrained persons. Power tools are dangerous in the hands of untrained users.
