Step-by-Step Guide: How to Change the Blade on a Dewalt Reciprocating Saw
This guide focuses on the quick release blade Dewalt mechanism, which is prevalent in most modern Dewalt reciprocating saws.
Step 1: Prepare Your Saw
- Disconnect Power: As mentioned, unplug the corded saw or remove the battery from your cordless model. Double-check that it’s disconnected.
- Position the Saw: Place the saw on a stable, flat surface. Ensure the blade you are removing is not pointing at anything.
Step 2: Remove the Old Blade
This is where the quick change blade reciprocating saw feature comes into play.
- Locate the Blade Clamp: Look at the front of the saw, where the blade inserts. You’ll see the blade clamp assembly.
- Engage the Release Mechanism:
- Rotary Collar Type: You will see a collar around the front of the saw’s shoe. Grip this collar firmly. Rotate it in the direction indicated (usually counter-clockwise, but there might be an arrow) until it stops. You might feel or hear a click.
- Lever Type: Some Dewalt models have a lever. You might need to pull this lever outwards or upwards to release the blade.
- Slide Out the Old Blade: Once the clamp is released, the old blade should slide out freely from the chuck. If it’s stuck, a gentle wiggle might help. Do not force it.
Tip for Stuck Blades: If the blade is stubborn, ensure the clamp is fully in the open position. Sometimes, debris can get lodged in the mechanism. A gentle tap with a rubber mallet on the clamp housing might dislodge it, but be careful not to damage the saw.
Step 3: Select and Prepare the New Blade
Now that the old blade is out, it’s time for Dewalt saw blade install.
- Choose the Right Blade: Select the appropriate blade for your cutting task. Consider the material, the thickness of the material, and the desired cutting speed or finish.
- Inspect the Blade: Before installing, check the new blade for any defects, such as bent teeth or cracks.
Step 4: Insert the New Blade
This is the core of how to insert blade reciprocating saw.
- Align the Blade: Note the orientation of the blade. Most blades are designed to cut when the teeth point downwards (for standard cuts) or upwards (for flush cuts or cutting overhead). The shank (the part that inserts into the saw) is usually flat on one side and rounded on the other. The flat side typically faces outwards or towards the front of the saw.
- Insert into the Chuck: Slide the shank of the new blade into the opened blade clamp. Make sure it goes in as far as it can.
- Secure the Blade:
- Rotary Collar Type: Rotate the collar back to its original position (usually clockwise). You should feel it lock into place.
- Lever Type: Release the lever. It should spring back and lock the blade securely.
- Test the Lock: Gently pull on the blade to ensure it is firmly secured. It should not wiggle or pull out. This step is crucial for proper blade installation reciprocating saw.
Step 5: Final Checks
- Re-attach Power: Once the new blade is securely installed and you’ve confirmed it’s locked, you can re-attach the battery or plug in the saw.
- Brief Test: Before starting your main cut, run the saw for a few seconds in a safe area (without the blade touching any material) to ensure the blade is spinning correctly and the saw is operating smoothly.
Switching Blades on a Dewalt Saw for Different Tasks
The ability to swap blades quickly is what makes a quick change blade reciprocating saw so valuable. Here’s a quick guide to blade selection for common tasks:
