Installing jigsaw blades on DeWalt 20-volt jigsaws can be a breeze! Here’s a step-by-step guide to help you get it done quickly and efficiently. Begin by ensuring that your jigsaw is off and the battery is disconnected. It’s crucial to work on a cooled-down jigsaw to prevent any burns.
Locate the blade ejection lever on the front of the saw. It is typically a small, spring-loaded lever. Push the lever away from you and simultaneously pull down the blade clamp. This will allow you to clear the path for the new blade. Next, align the new blade’s teeth facing downwards and insert it into the blade clamp. Carefully push the blade up until it is securely held in place. Release the blade clamp by pushing it towards you and lock the blade in place by engaging the blade ejection lever back into its original position. Ensure the blade is firmly seated by gently pulling on it.
Finally, reconnect the battery and turn on the jigsaw. Test the blade by making a few cuts on a scrap piece of wood. If the blade cuts smoothly without any wobbling or vibration, you have successfully installed the blade. Remember, it’s indispensable to wear gloves and safety glasses throughout the process for your protection.
Disassembling the Jigsaw
Before you can insert a new blade into your DeWalt 20V jigsaw, you must first disassemble the tool. Follow these steps to do so safely and efficiently:
1. Unplug the Jigsaw
First and foremost, it is crucial to unplug the jigsaw from the power source. This safety precaution prevents accidental activation while disassembling the tool. Locate the power cord and disconnect it at the plug.
Once the jigsaw is unplugged, you can proceed to the next steps.
2. Remove the Shoe Insert
The shoe insert is a small, removable piece located on the base of the jigsaw. To remove it, simply grasp the insert with your fingers or a pair of pliers and pull it straight out. This will expose the blade clamp mechanism below.
3. Open the Blade Clamp
With the shoe insert removed, you will see a metal blade clamp. To open the clamp, locate the lever or knob on the side of the jigsaw and rotate it counterclockwise. This will loosen the clamp and allow you to insert or remove the jigsaw blade safely.
4. Remove the Old Blade
Once the blade clamp is open, you can remove the old blade. Grip the blade firmly with one hand and gently pull it straight up out of the clamp. If the blade is stuck, you may need to use a pair of pliers or a screwdriver to help pry it loose.
Inserting the New Blade
Once you’ve selected the appropriate blade for your project, it’s time to insert it into the jigsaw. Here’s a detailed step-by-step guide:
Step 1: Remove the Base Plate
Loosen the screws holding the base plate in place using an Allen key or wrench. Carefully lift off the base plate to expose the blade clamp.
Step 2: Open the Blade Clamp
Locate the lever or dial that releases the blade clamp. Press or turn the release mechanism to open the clamp and allow the insertion of the new blade.
Step 3: Insert the Blade
Align the teeth of the new blade with the guide slots on the blade clamp. Insert the blade into the clamp ensuring that the teeth are facing in the correct direction. The blade should be inserted with the teeth pointing downward for cutting on the upstroke and upward for cutting on the downstroke.
| Cutting Direction | Teeth Orientation |
|---|---|
| Upstroke (Cutting on the way up) | Teeth facing downward |
| Downstroke (Cutting on the way down) | Teeth facing upward |
Tip: If you’re unsure of the correct teeth orientation, consult your jigsaw’s manual or check the manufacturer’s website for specific guidance.
Step 4: Close the Blade Clamp
Once the blade is inserted, press or turn the release mechanism again to close the blade clamp. Ensure that the blade is securely held in place without any wobble.
Step 5: Reattach the Base Plate
Place the base plate back onto the jigsaw and tighten the screws to secure it. Your new jigsaw blade is now installed and ready for use.
Securing the Blade
4. Tightening the Blade: A Comprehensive Guide
Once the blade is seated correctly, it’s crucial to tighten it securely. Use the provided wrench or key to hold the retaining bolt still while you turn the nut clockwise using the other hand. Ensure you have a firm grip and apply enough force to snugly fasten the blade, but avoid overtightening as it may warp or damage the blade. To ensure proper tightness, use a torque wrench set to the manufacturer’s recommended torque specification. However, if you’re working without a torque wrench, aim for a snug fit that allows the blade to move freely without excessive play.
| Tip | Explanation |
|---|---|
| Secure the blade firmly, but don’t overtighten | Overtightening can warp or damage the blade |
| Use a torque wrench for precise tightening | Ensures proper tightness without damaging the blade |
| Aim for a snug fit without excessive play | Allows the blade to move freely during cutting |
Adjusting Blade Tension
Once you’ve inserted the blade, you’ll need to adjust the blade tension to ensure it’s held securely. Most DeWalt jigsaws have a tool-less blade tension lever or knob that allows you to easily adjust the tension without the need for a hex key or other tools. Here’s how to adjust the blade tension:
- Identify the blade tension adjustment lever or knob on your specific DeWalt jigsaw model.
- Hold the lever or knob and turn it counterclockwise to loosen the blade tension.
- Insert the blade into the jigsaw and tighten the lever or knob clockwise until the blade is held firmly in place.
- Test the blade tension by gently pulling on the blade. It should feel snug but not overly tight.
- If the blade moves too easily or rattles, tighten the tension lever or knob further. If the blade is too tight, it may bind or break during operation, so loosen the tension slightly.
Tips for Adjusting Blade Tension
- Different blades may require different tension settings. Thinner blades generally require less tension than thicker blades.
- Always check the blade tension before each use to ensure it’s secure and properly adjusted.
- Avoid overtightening the blade tension, as this can damage the blade or the jigsaw mechanism.
Safety Precautions
1. Wear Safety Gear: Always wear eye protection, gloves, and a dust mask when working with power tools.
2. Unplug Power Tool: Before performing any maintenance or adjustments, ensure that the jigsaw is unplugged from the power source.
3. Inspect Blade: Check the blade for any damage or wear before installation. Do not use a damaged blade.
4. Keep Clear of Blade: Keep your hands and fingers away from the blade area while the jigsaw is running.
5. Securely Clamp Workpiece: Secure the workpiece firmly before starting to cut. This will prevent the material from moving during the cutting process.
6. Avoid Kickbacks: Maintain a firm grip on the jigsaw and use both hands to control the tool. Avoid cutting into materials that are too thick or hard, as this can cause kickbacks.
7. Use Correct Blade: Choose the correct blade for the material you are cutting. Incorrect blade selection can lead to ineffective cutting and potential hazards.
8. Follow Manufacturers’ Instructions: Refer to the manufacturer’s instructions for specific safety guidelines and maintenance procedures.
9. Additional Precautions for 20 Volt DeWalt Jigsaws:
- Remove Battery Before Changing Blade: Always remove the battery from the jigsaw before changing the blade.
- Locate Blade Clamp Lever: Identify the blade clamp lever on the jigsaw, usually located near the blade housing.
- Pull Up Clamp Lever: Pull up the blade clamp lever to release the blade.
- Remove Old Blade: Grip the old blade firmly with gloved hands and pull it straight out of the blade holder.
- Insert New Blade: Align the new blade with the blade holder and insert it securely.
- Secure Blade: Push down on the blade clamp lever to secure the new blade in place.
- Inspect Blade Installation: Ensure that the blade is properly installed and securely fastened before continuing.
