Setup

1. Battery Installation and Removal

The DEWALT DCS334B is a bare tool and requires a DEWALT 20V MAX XR battery pack (not included).

1. To install the battery: Align the battery pack with the tool's battery port. Slide the battery pack into the tool until it locks securely in place.
2. To remove the battery: Press the battery release button and pull the battery pack out of the tool.

2. Blade Installation and Removal

This jig saw accepts T-shank jig saw blades.

1. Ensure the battery pack is removed from the tool.
2. Lift the all-metal, lever-action keyless blade clamp.
3. Insert the T-shank blade fully into the blade clamp opening with the teeth facing forward.
4. Release the blade clamp lever. Gently pull on the blade to ensure it is securely locked.
5. To remove, lift the blade clamp lever and pull the blade out.

3. Shoe Bevel Adjustment

The shoe can be beveled for angled cuts up to 45 degrees.

1. Ensure the battery pack is removed.
2. Locate the keyless shoe bevel adjustment lever.
3. Release the lever and adjust the shoe to the desired angle. Detents are provided at 0°, 15°, 30°, and 45°.
4. Securely lock the lever after adjustment.

4. Installing the No-Mar Shoe Cover

Use the no-mar shoe cover to protect delicate work surfaces from scratches.

1. Align the shoe cover with the base of the jig saw shoe.
2. Snap the cover into place, ensuring it is flush and secure.
3. To remove, gently pry off the cover.

Operating Instructions

1. Powering On and Off

• To turn on: Depress the variable speed trigger. The LED work light will activate.
• To turn off: Release the variable speed trigger.

2. Adjusting Speed

The jig saw features both a variable speed trigger and a speed adjustment dial.

• The speed adjustment dial (located above the trigger) sets the maximum blade speed (up to 3,200 strokes per minute). Rotate the dial to select the desired maximum speed.
• The variable speed trigger allows for fine-tuning of the speed from zero up to the maximum set by the dial. Press the trigger lightly for slower speeds and more firmly for faster speeds.

3. Orbital Action Control

The 4-position orbital action allows you to adjust the aggressiveness of the cut.

1. Position 0 (straight cut): For fine, splinter-free cuts in wood, or for cutting metal.
2. Positions 1-3 (orbital cuts): For faster, more aggressive cuts in wood and softer materials. Higher numbers indicate more aggressive orbital action.

Select the appropriate orbital setting based on the material and desired cut quality.

4. Cutting Techniques

• Starting a Cut: Place the front edge of the shoe flat on the workpiece. Start the tool before the blade contacts the material.
• Following a Line: Guide the tool along the marked cut line. The integrated dust blower helps keep the line visible.
• Curved Cuts: Use a narrower blade and a lower orbital setting for tighter curves.
• Plunge Cuts: For plunge cuts, refer to advanced techniques or consult the full PDF manual for detailed instructions.
