Maintaining your tools is crucial for keeping them in optimal working condition, especially when it comes to power tools like the Dewalt DW707 chop saw. Among the most important maintenance tasks is changing the brushes. In this comprehensive guide, we will explore everything you need to know about changing the brushes on your Dewalt DW707 chop saw. From understanding why this task is essential to step-by-step instructions, you will be equipped with the knowledge to carry out this procedure efficiently and confidently.
Why Is Changing Brushes Vital?
Changing the brushes in a chop saw is not just a maintenance chore; it significantly affects the tool’s performance and longevity. Here are some reasons why this task is essential:
Performance Optimization
Over time, brushes wear down due to constant friction, which can lead to a decrease in motor performance. Worn brushes may cause inadequate power transfer, resulting in reduced cutting efficiency and accuracy.
Preventing Damage
If you allow worn brushes to remain in the chop saw, they can damage the armature or the commutator. This kind of damage can be costly to repair, making it a far more budget-friendly option to replace the brushes as soon as they show signs of wear.
Extended Lifespan
Regular maintenance, including brush replacement, can extend the life of your Dewalt DW707. Keeping your tool in good condition allows it to serve you faithfully for longer.
Identifying When to Change Brushes
Recognizing when it’s time to change your brushes is key to maintaining your tool’s effectiveness. Here are a few signs to watch for:
- Decreased Power: If you notice that the motor struggles to maintain speed, it might be due to worn brushes.
- Noisy Operation: Excessive noise during operation could indicate a problem with the brushes.

Step-by-Step Guide to Changing Brushes on Dewalt DW707
Now that you’re equipped with the tools and knowledge of why this maintenance is necessary, let’s walk through the process step-by-step.
Step 1: Safety First
Before you begin any maintenance work on your chop saw, always prioritize safety. This means:
1. Unplug the Saw
Ensure that the chop saw is completely unplugged from the power source to avoid accidental activation.
2. Wear Safety Goggles
Always wear safety goggles to protect your eyes from debris that may be released during the maintenance process.
Step 2: Remove the Side Cover
Using your screwdriver, carefully remove the screws securing the side cover of the chop saw. Set the screws aside in a safe, easily identifiable place so that you can find them when you’re ready to reassemble.
Step 3: Locate the Brushes
Once the side cover has been removed, locate the brush holders. The brushes will usually be found near the motor. You should be able to see two brush holders, one for each brush.
Step 4: Remove the Old Brushes
To remove the old brushes:
1. Release the Tension
Gently pull the springs or clips that hold the brushes in place. Be careful to avoid applying too much force, which may cause damage.
2. Extract the Brushes
Pull the brushes out of the holders. Inspect them for wear; if they appear significantly worn down, they need replacing.
Step 5: Prepare the New Brushes
Before installing your new brushes, it’s essential to prepare them:
1. Clean the Slot
Use compressed air to blow out any dust or debris in the brush holder slots. This ensures a clean fit for the new brushes.
2. Compare New and Old Brushes
Make sure the new brushes match the size and shape of the old ones. This is crucial for proper function.
Step 6: Install the New Brushes
Now that your new brushes are ready:
1. Insert the New Brushes
Carefully place the new brushes into their holders. Make sure they fit snugly.
2. Secure the Brushes
Gently press the springs or clips back into place to secure the brushes.
Step 7: Reassemble the Saw
With the new brushes installed, it’s time to put everything back together:
1. Replace the Side Cover
Carefully align and replace the side cover. Ensure that it fits properly and securely.
2. Tighten the Screws
Using your screwdriver, tighten the screws to keep the side cover secure. Double-check that everything is snug but avoid over-tightening.
Step 8: Test the Chop Saw
Finally, it’s crucial to test your chop saw before returning to work:
1. Plug in the Saw
Reconnect your chop saw to the power supply.
2. Perform a Test Run
Start the saw and observe its operation. Listen for any unusual noises, and check for smooth and powerful performance.
Common Issues When Changing Brushes
While changing brushes is a relatively straightforward task, you may encounter some common issues. Here’s how to handle them:
Brushes Not Fitting Properly
If the new brushes don’t seem to fit:
1. Double-Check Compatibility
Ensure that the brushes are indeed the right model for your Dewalt DW707.
2. Inspect the Holder
Look for any debris or damage inside the brush holder that could prevent a proper fit.
Difficulty Removing Old Brushes
In some cases, you may find the old brushes are difficult to remove:
1. Gentle Tapping
If the brushes are stuck, a gentle tap with a soft tool may help dislodge them.
2. Apply Lubrication
Applying a small amount of lubricant can assist in freeing stubborn brushes, but exercise caution to avoid over-application.
