Fixing the DeWalt DW705: Step-by-Step Guide
To effectively fix your DeWalt DW705, it’s imperative to follow a systematic approach. Here’s how to tackle each common problem:
Fixing a Saw that Won’t Start
When your DeWalt DW705 refuses to start, it could stem from several sources. To diagnose and fix the issue, follow these detailed steps:
Step 1: Check the Power Source
- Ensure that the saw is plugged in securely. A loose connection may halt operations.
- Check your extension cord (if used) for any damage. Replace it if necessary.
Step 2: Inspect the On/Off Switch
- Remove the rear cover of the saw to examine the switch.
- Ensure it is clean and free from debris. If damaged, it may require replacement.
Step 3: Test the Motor
- Use a multimeter to test the motor for continuity. Set your multimeter to the ohm setting and check the motor’s windings.
- If there’s no continuity, your motor may be faulty and require replacement.
Step 4: Examine Internal Wiring
- Inspect the internal wiring for any signs of fraying or disconnection.
- If you find any damaged wires, they will need to be repaired or replaced.
Step 5: Check the Circuit Breaker
- Sometimes, the issue may be more simple: check your circuit breaker and reset it if it has tripped.
Fixing Inaccurate Cuts
If your DeWalt DW705 is producing inaccurate cuts, it’s crucial to identify the root cause. Follow these steps to resolve the issue:
Step 1: Check the Blade Alignment
- Use a square to ensure the blade is aligned with the miter slot.
- If misaligned, adjust the blade’s alignment according to the manufacturer’s instructions.
Step 2: Inspect the Blade
- Examine the condition of the blade. A dull or damaged blade can cause poor cuts.
- If needed, either sharpen the blade or replace it with a new one.
Step 3: Adjust the Bevel and Miter Settings
- Make sure the bevel and miter angles are set correctly according to your cut specifications.
- Always recheck the settings after making adjustments.
Step 4: Secure the Workpiece
- Ensure that the material you are cutting is properly secured. Using clamps can help stabilize the workpiece and produce consistent cuts.
Fixing Excessive Vibration
Excessive vibration can lead to imprecise cuts and may even affect the longevity of your saw.
Step 1: Inspect the Blades
- Ensure that the blades are sharp and free from debris.
- Check if the blade is properly mounted. Unevenly fixed blades can lead to vibrations.
Step 2: Examine the Motor Mounts
- Check the motor’s mounting screws to ensure they are secure. Loose mounts can result in unnecessary vibrations.
Step 3: Use a Thicker Base
- If the vibration persists, consider using a more stable or thicker base for your miter saw.
- An unstable surface can amplify vibration.

What common issues can occur with the DeWalt DW705 Compound Miter Saw?
The DeWalt DW705 Compound Miter Saw may experience several common issues, including misalignment of the blade, difficulty in adjusting the miter angles, and a failure to start. Misalignment can lead to inaccurate cuts, making it crucial to regularly check the calibration of your saw. Ensure that the blade is mounted correctly and that the saw’s pivot points are properly lubricated for smooth operation.
Additionally, the saw might encounter problems during miter angle adjustments, which can stem from wear and tear on the adjustment mechanism. Over time, the tightening knobs or levers may become loose or damaged. It’s important to inspect these components frequently and replace them if you notice any abnormalities to maintain precision and efficiency during your projects.
How do I troubleshoot a DeWalt DW705 that won’t start?
If your DeWalt DW705 Compound Miter Saw fails to start, the first step is to check the power source. Ensure that the saw is plugged in and that the outlet is functional. You can do this by testing it with another device. If the outlet works, inspect the power cord for any signs of damage or fraying, which can prevent electricity from reaching the saw.
If the power source is not the issue, examine the switch and trigger. Sometimes, dust or debris can accumulate around these areas, causing the saw to be unresponsive. Cleaning around the switch and ensuring it is functioning appropriately is essential. If the saw still doesn’t start, consider checking the internal circuitry or consulting a professional technician for repairs.
What should I do if my miter angles are not accurate?
If you find that the miter angles on your DeWalt DW705 are not cutting accurately, the first step is to check the calibration of the detent system. The detents are pre-set angles that help you achieve exact cuts, and they could become misaligned over time. You can calibrate the saw by adjusting the set screws on the miter scale and realigning stop points to ensure they match the angles indicated on the scale.
Additionally, inspect the fence and table for any warping or damage, as this can also affect cutting accuracy. Ensure that the fence is squared up to the blade by measuring the distance from the blade to the fence at both the front and back. If discrepancies are found, adjust the fence accordingly to guarantee a straight guide for your cuts.
How can I replace the blade on the DeWalt DW705?
Replacing the blade on the DeWalt DW705 Compound Miter Saw is a straightforward process that requires a few tools. Begin by unplugging the saw to ensure safety during the replacement. Next, use the provided blade wrench, usually stored on the saw, to loosen and remove the arbor nut. After this, carefully remove the old blade, ensuring you’re following the arrows indicating the direction of rotation.
Once the old blade is removed, place the new blade onto the arbor, ensuring it is positioned correctly and aligned with the direction of rotation. Replace the arbor nut and tighten it securely with the wrench. After confirming that everything is firmly in place, plug the saw back in and test it briefly to ensure the blade is operating smoothly.
How do I maintain my DeWalt DW705 to prevent common issues?
Regular maintenance is crucial for the optimal performance of your DeWalt DW705 Compound Miter Saw. Start by cleaning dust and debris from the saw after each use, focusing on the blade, table, and components. A clean workspace prevents accumulation that can interfere with the saw’s functionality and accuracy. Additionally, make it a habit to lubricate moving parts, such as pivot points and the miter adjustment mechanism, to ensure smooth operation.
Another aspect of maintenance includes regularly checking for loose screws and bolts. Over time, vibrations can cause components to loosen. Periodically inspect the saw’s hardware and tighten any loose parts to maintain stability. Lastly, keep the blade sharp and replace it when it shows signs of wear; a dull blade can lead to unnecessary strain on the motor, thereby extending the life of your saw.
Can I use a different blade type with my DeWalt DW705?
You can use a variety of blade types with your DeWalt DW705 Compound Miter Saw, as long as they fit the size specifications and meet the saw’s requirements. The standard blade size for the DW705 is 12 inches, and the arbor size is typically 1 inch. Ensure that the blade is designed for miter saws to achieve optimal performance and safety.
However, keep in mind that different blades serve various purposes based on the material you’re cutting. For instance, a blade designed for fine woodworking will provide cleaner cuts, while a blade meant for cutting construction materials might be more efficient at making rough cuts. Always choose the blade appropriate for your specific task to maximize the efficiency and longevity of both the blade and the saw.
What safety precautions should I follow while using the DeWalt DW705?
Safety should always be a priority when using any power tools, including the DeWalt DW705 Compound Miter Saw. Always wear appropriate personal protective equipment (PPE), such as safety goggles, ear protection, and a dust mask, to shield yourself from debris and noise. Additionally, ensure that your hair is tied back and that loose clothing or jewelry is secured away from moving parts to prevent accidents.
Before starting the saw, familiarize yourself with the controls and ensure that your workspace is clear of any obstacles. When making a cut, keep both hands away from the blade path, and always use the proper push sticks or supports when necessary. Lastly, never attempt to remove or adjust the workpiece while the saw is running; always wait until the blade has come to a complete stop before making any adjustments or handling materials.
