Makita circular saws are known for their precision and durability, making them a popular choice among woodworkers and DIY enthusiasts. However, like any power tool, they can encounter issues over time. One common problem users might face is a malfunctioning brake.
If the brake on your Makita circular saw is not working as it should, it can pose serious safety concerns. In this article, we will explore the potential reasons behind makita circular saw brake not working issue and provide you with solutions to get your saw’s brake back in working order.
Understanding the Makita Circular Saw Brake System
Before delving into troubleshooting, it’s essential to understand how the brake system in a Makita circular saw works.
The brake’s primary function is to stop the spinning blade quickly when you release the trigger, enhancing safety during and after cutting.
This is achieved by reversing the flow of electricity in the motor, effectively slowing down and stopping the blade’s rotation.
Makita Circular Saw Brake Not Working (7 Fixes)
Here we have provided 7 practical fixes for Makita circular saw brake not working.
Clean the Commutator:
Over time, the brake’s effectiveness can diminish due to a dirty commutator. The commutator is a critical component that enables the brake to function correctly.
To address this issue, follow these steps:
- Ensure the saw is unplugged and in a safe, stable position.
- Let the saw rev at full speed for a minute to clean the commutator.
- Observe if the brake’s performance improves.
Cleaning the commutator is a simple and cost-effective solution that can restore the brake’s functionality.
It is worth noting that you should regularly clean the commutator to prevent future issues.
Replace the Motor Brushes:
The motor brushes are essential for establishing a good connection with the commutator.
If they are worn or not seated properly, they can prevent the brake from working effectively. Here’s how to address this problem:
- Disconnect the saw from the power source.
- Remove the motor brushes carefully.
- Replace the worn or improperly seated brushes with new ones.
- Reassemble the saw and test the brake’s functionality.
Replacing the motor brushes can often resolve issues with the brake. It’s crucial to choose compatible brushes and follow the manufacturer’s guidelines for replacement.
Check the Armature:
If the motor brushes are excessively burnt, chipped, or broken, it’s essential to inspect the armature before replacing them.
A damaged armature can negatively impact the new brushes' lifespan and the brake’s effectiveness.
- Disconnect the saw from the power source.
- Inspect the armature for any signs of damage or wear.
- If the commutator is damaged, consider addressing that issue first to prevent premature brush wear.
A damaged armature may require professional assistance or a complete replacement, depending on the extent of the damage.
Check the Field and Armature Brushes:
The brake system operates using the field and armature brushes, and any dirt or debris can hinder its activation. Be sure to check the following:
- Disconnect the saw from the power source.
- Clean the field and armature brushes, ensuring they are free from any obstructions.
- Verify that the blade is securely attached and not loose.
Keeping the field and armature brushes clean is essential for optimal brake performance, and a loose blade can pose a safety hazard.
Check the Brake Mechanism:
If the brake mechanism itself is damaged or worn, it may require professional repair or replacement.
This is a more complex task, and unless you have experience with power tool repairs, it’s advisable to seek help from a qualified technician.
Damaged brake mechanisms should not be ignored, as they compromise the safety of the tool.
Proper Saw Usage:
Preventing brake issues begins with proper saw usage. Ensure you follow these guidelines:
Use the appropriate blade for the material you are cutting. This ensures the saw operates efficiently and reduces strain on the brake system.
Avoid forcing the saw through the material. Let the blade do the work, and use a steady, controlled motion.
Regularly check that the blade is securely tightened and that the saw is adequately lubricated to prevent undue stress on the brake.
Consider Upgrading to a Newer Model:
If your Makita circular saw is older or has endured heavy use, it may be worth considering upgrading to a newer model.
Newer saws often incorporate advanced safety features and improved brake systems, reducing the risk of accidents and enhancing overall performance.
Conclusion:
A malfunctioning brake on a Makita circular saw is a serious concern that can jeopardize your safety while using the tool.
However, by understanding the brake system and following the troubleshooting steps mentioned in this article, you can often diagnose and resolve the issue on your own.
Remember to maintain your saw regularly, clean the commutator, replace motor brushes when necessary, and follow proper usage guidelines to extend the life of your tool and keep it in peak working condition.
If you encounter more complex issues with the brake or suspect damage to the brake mechanism, do not hesitate to seek professional assistance.
In the end, ensuring that your Makita circular saw is operating safely and efficiently is paramount, allowing you to complete your woodworking and DIY projects with confidence.
