2. Setup and Assembly

2.1 Battery Installation

1. Ensure the jig saw is turned off.
2. Align the battery pack with the battery port on the tool.
3. Slide the battery pack into the port until it clicks securely into place.
4. To remove, press the release button on the battery pack and slide it out.

2.2 Blade Installation (Tool-Free)

1. Ensure the tool is disconnected from its power source (battery removed).
2. Locate the tool-free blade clamp lever on the front of the jig saw.
3. Push the lever forward to open the blade clamp.
4. Insert the T-shank jig saw blade into the clamp opening, ensuring the teeth face forward.
5. Release the lever; it should snap back into place, securing the blade. Gently pull on the blade to confirm it is firmly seated.
6. To remove the blade, push the lever forward again, and the blade will eject.

2.3 Footplate Adjustment

The footplate can be adjusted for bevel cuts. Refer to the markings on the footplate for common angle settings. Loosen the footplate adjustment screws, set the desired angle, and securely tighten the screws before operation.

3. Operating Instructions

3.1 Powering On/Off

• To turn on the jig saw, press the trigger switch. The LED light will illuminate the work area.
• To turn off, release the trigger switch.
• For continuous operation, press the lock-on button while the trigger is depressed. To release, press the trigger again.

3.2 Adjusting Speed and Orbital Action

• Variable Speed Dial: Rotate the speed dial to select the desired maximum stroke rate (0-3,500 SPM). Lower speeds are suitable for delicate cuts or harder materials, while higher speeds are for faster cuts in softer materials.
• Variable Speed Trigger: The trigger allows for fine-tuning of the speed within the range set by the dial. Pressing the trigger further increases the speed.
• Orbital Action Selector: Use the orbital action selector to choose one of the four settings. Setting 0 is for straight cuts and fine finishes. Higher settings (1-3) provide more aggressive cutting for faster material removal, especially in wood, but may result in a rougher cut.

3.3 Cutting Procedures

1. Secure Workpiece: Always clamp the workpiece firmly to prevent movement during cutting.
2. Select Blade: Choose the appropriate T-shank blade for the material and desired cut type (e.g., wood, metal, curve, straight).
3. Adjust Settings: Set the speed dial and orbital action according to the material and cut requirements.
4. Position Tool: Place the footplate flat on the workpiece, ensuring the blade is clear of the material before starting.
5. Start Cut: Depress the trigger and allow the blade to reach full speed before engaging the material. Guide the saw along the cut line with steady pressure.
6. Maintain Visibility: The dust blower and LED light will help keep the cut line visible.
