Maintaining your DeWalt DW705 miter saw is essential for optimal performance and longevity. One of the key maintenance tasks involves changing the brushes. Over time, the brushes wear down due to friction and electrical current, leading to decreased performance and, in some cases, motor failure. In this comprehensive guide, we will walk you through the steps to change brushes on your DeWalt DW705, ensuring you can keep your tool running smoothly and efficiently.
Understanding the Importance of Brush Maintenance
Before we get into the step-by-step process, it’s crucial to understand why brush maintenance is vital. The brushes in your DeWalt DW705 play a significant role in:
1. Electrical Conductivity
The brushes facilitate a vital electrical connection between the stationary parts and the rotating parts of the motor. As brushes wear down, this connection can weaken, leading to inefficiency or, worse, electrical failure.
2. Tool Longevity
Changing the brushes at regular intervals can extend the life of your tool. Worn brushes can lead to overheating and even permanent motor damage, which can be costly to repair.
3. Performance Consistency
For professionals and hobbyists alike, maintaining the performance of your tools is essential. Regularly replacing brushes can ensure your miter saw operates at peak performance, delivering smooth cuts and precise angles.
Signs That It’s Time to Change the Brushes
Recognizing the signs indicating it’s time to replace your brushes can save you from unexpected downtimes and repair costs. Here are some common indicators:
- Excessive Sparking: If you notice increased sparking around the brushes during operation, it’s time for a change.
- Decreased Power: A sudden drop in cutting power can also signal worn brushes.
Tools and Materials You Will Need
Before starting the process, gather all the necessary tools and materials:
- Replacement Brushes: Make sure to buy specific brushes compatible with the DeWalt DW705.
- Screwdriver: A Phillips-head screwdriver is typically required.
- Wrench or Socket Set: Depending on your model, you might need this to remove the motor cover.
- Multimeter: Optional for checking electrical problems.
- Protective Gear: Safety glasses and gloves are recommended.
Step-by-Step Guide to Changing Brushes on a DeWalt DW705
Changing the brushes on the DeWalt DW705 can be a straightforward task if you follow the steps outlined below carefully.
Step 1: Power Off and Unplug the Tool
The first and most important step in changing the brushes is ensuring that the saw is not connected to a power source. This will help prevent any accidental startups or electrical shocks.
Step 2: Remove the Motor Cover
Using a screwdriver or wrench, remove the screws or bolts holding the motor cover in place. Carefully set the motor cover aside to gain access to the brush housing. Keep all screws organized as you will need them to reassemble the tool.
Step 3: Locate the Brush Holders
The brush holders are usually located on either side of the motor. You will see the brushes housed within these holders. Each holder will likely have a retaining clip or screw keeping the brush in place.
Step 4: Remove the Old Brushes
Using a pair of pliers, carefully pull the brush out of its holder. Be cautious not to damage any surrounding components during this process. Check for any signs of excess wear or damage on both the brushes and the holders.
Step 5: Insert the New Brushes
Take the new brushes and insert them into the holders. Ensure they fit snugly and that the spring mechanism is functioning correctly. A poorly seated brush can lead to poor performance and additional wear.
Step 6: Reattach the Motor Cover
After ensuring that the new brushes are securely in place, it’s time to reattach the motor cover. Align it correctly and fasten it with the screws or bolts you previously removed.
Step 7: Power On and Test the Tool
After everything is secured, plug in your DeWalt DW705 and turn it on. Observe whether it operates smoothly and without excessive sparking. This testing phase is crucial to ensure everything is functioning as intended.
Step 8: Routine Check and Maintenance
To prevent issues in the future, make it a habit to check your brushes regularly. Depending on how often you use your saw, consider creating a schedule for maintenance checks every few months.
Tips for Successful Brush Replacement
Here are some additional tips to facilitate a successful brush replacement on your DeWalt DW705:
1. Buy Quality Replacement Brushes
Always opt for high-quality, OEM (Original Equipment Manufacturer) brushes designed specifically for the DeWalt DW705. Cheap imitations may not perform well and could lead to further electrical issues.
2. Wear Protective Gear
Even though this task may seem straightforward, wearing protective gear can safeguard against any unexpected accidents such as electric shocks or debris.
