How to Effortlessly Install DeWalt Jigsaw Blades (20 Volt): A Step-by-Step Guide

Installing Dewalt jigsaw blades on a 20-volt model is a straightforward process, even for novice users. With the right tools and a few simple steps, you can quickly and easily equip your jigsaw with the appropriate blade for your cutting needs. Whether you’re tackling intricate curves in wooden planks or slicing through metal sheets, having the correct blade installed ensures precise cuts and optimal performance.

Before you begin, gather the necessary tools: the jigsaw blade and a hex key. Ensure that the jigsaw is unplugged and the blade guard is in place. To remove the old blade, use the hex key to loosen the screw holding it in place. Carefully detach the old blade and discard it properly. Now, align the new blade with the blade clamp on the jigsaw. Insert the blade’s tang into the clamp and tighten the screw using the hex key until it’s snug but not overtightened.

Finally, ensure the blade guard is properly attached and that the jigsaw is plugged in before making any cuts. Test the blade on a scrap piece of material to verify that it’s cutting smoothly and accurately. Remember to follow all safety precautions when using power tools, such as wearing appropriate eye and ear protection, and always unplug the jigsaw before changing blades. By following these steps, you’ll have your Dewalt jigsaw up and running with a new blade in no time, ready to tackle any cutting project with confidence.

Removing the Blade Guard

The blade guard on a DeWalt 20-volt jigsaw is essential for protecting the user from accidental contact with the blade, but it must be removed in order to change the blade. Here’s a step-by-step guide on how to remove the blade guard:

Unplug the Jigsaw: Always ensure that the jigsaw is unplugged before performing any maintenance or repairs. This prevents the risk of accidental activation.
Locate the Blade Guard Release Lever: The blade guard release lever is typically located on the top or side of the jigsaw housing. It is usually a small, spring-loaded lever.
Slide the Blade Guard Release Lever: Slide the blade guard release lever in the direction indicated by the arrow or icon on the jigsaw housing. This will disengage the guard from its locking position.
Lift the Blade Guard: Once the blade guard release lever is engaged, gently lift the guard up and away from the base of the jigsaw. It should pivot easily on the hinge pin or bracket.
Pull the Blade Guard Forward: Once the guard is lifted, pull it towards the front of the jigsaw until it disengages from the base and can be completely removed.
Inspect the Blade Guard: Before reinstalling the blade guard, take a moment to inspect it for signs of damage or wear. If any damage is found, replace the blade guard immediately to ensure user safety.
Lubricate the Hinge Pin (Optional): For smooth operation and to prevent seizing, it’s recommended to apply a small amount of light machine oil or lubricant to the hinge pin or bracket where the blade guard pivots.
Reinstall the Blade Guard: To reinstall the blade guard, simply reverse the removal steps. Position the guard back on the base of the jigsaw and slide it into place.
Engage the Blade Guard Release Lever: Ensure that the blade guard is properly seated and then slide the blade guard release lever back to its locked position.
Test the Blade Guard Operation: Before using the jigsaw, always check that the blade guard is securely attached and pivots smoothly. Move the guard through its full range of motion to ensure it operates as intended.

Cutting Curves with a Jigsaw

Jigsaws are versatile tools that can cut intricate curves in a variety of materials, making them ideal for projects such as cabinetry, woodworking, and crafting. To get the most out of your jigsaw, it’s important to properly install the blades. Here is a step-by-step guide to installing Dewalt jigsaw blades in a 20-volt cordless jigsaw:

1. Safety First

Before handling any power tools, it’s crucial to wear appropriate safety gear. This includes safety glasses, earplugs, and gloves. Ensure that the jigsaw is unplugged or the battery is removed for added safety.

2. Locate the Blade Clamping Lever

Find the blade clamping lever on the side of the jigsaw. It usually has a lever or a knob that you can move up or down.

3. Lift the Blade Clamping Lever

Push or pull the blade clamping lever upwards to release the tension on the blade clamp.

4. Remove the Old Blade (if applicable)

If there is an existing blade installed, grip it firmly and pull it straight out from the jigsaw.

5. Insert the New Blade

Align the shank of the new blade with the blade slot in the jigsaw. Make sure the teeth of the blade are facing in the correct direction for the type of cut you want to make.

6. Tighten the Blade Clamping Lever

Push the blade clamping lever down to secure the blade. Ensure that the blade is held tightly, but avoid overtightening, which can damage the blade or the jigsaw.

7. Test the Blade

Make a few practice cuts on a scrap piece of material to ensure that the blade is cutting properly and that there is no vibration or chatter.

8. Blade Selection

Choosing the right blade for your project is essential. Blades come in various sizes, shapes, and materials. Consider the following factors:

Material: Different materials, such as wood, metal, or plastic, require specific blade types.
Thickness: The thickness of the material determines the length of the blade you need.
Tooth Count: A higher tooth count results in smoother cuts, while a lower tooth count yields faster cuts.
Blade Length: Longer blades provide greater reach, but they may also vibrate more.

9. Blade Care and Maintenance

To prolong the life of your jigsaw blades, follow these tips:

Clean the Blades: Wipe down the blades with a damp cloth after each use to remove resin or debris.
Sharpen the Blades: Regularly sharpen the blades to maintain optimal cutting performance.
Replace Worn Blades: Replace blades that show signs of excessive wear, such as chipping or dullness.

10. Blade Types for Cutting Curves

Jigsaw blades for cutting curves come in various types, each with its unique characteristics:

Scroll Blades: Thin, narrow blades designed for intricate cuts.
Reverse-Tooth Blades: Blades with teeth pointing in the opposite direction, providing a smooth finish on the cut edge.
Vari-Tooth Blades: Blades with varying tooth sizes, allowing for faster and cleaner cuts.

11. Cutting Techniques

Mastering proper cutting techniques will enhance your results:

Use a Guide: A straightedge or a guide can help you make precise cuts.
Control the Speed: Adjust the jigsaw speed according to the material and blade type.
Follow the Grain: Cut with the grain of the material to minimize chipping or breakage.

12. Common Problems and Solutions

Problem	Solution
Blade Vibrates	Use a shorter blade or reduce the jigsaw speed.
Blade Bends or Breaks	Choose a blade with a higher tooth count or reduce the cutting pressure.
Blade Cuts Too Slowly	Try a blade with fewer teeth or increase the jigsaw speed.
Blade Gets Jammed	Unplug the jigsaw and remove the blade. Check for obstructions and clean the blade.

13. Additional Tips

Practice on scrap material before cutting your actual workpiece.
Test different blade types to find the one that works best for your project.
Stay patient and take your time to achieve the desired results.
