- Push the lever to open the blade clamp.
- Insert the T-shank of the desired blade into the clamp opening until it clicks into place. Ensure the blade teeth face forward.
- Release the lever. Gently pull on the blade to confirm it is securely seated.
- To remove, repeat steps 2 and 3, then pull the blade out.
4.3 Dust Extraction Connection
For a cleaner work environment, connect the provided dust extraction pipe to the dust extraction port at the rear of the jigsaw. Attach the other end of the pipe to a suitable vacuum cleaner or dust extraction system.
4.4 Parallel Guide Installation
The parallel guide assists in making straight cuts parallel to an edge. Insert the guide rod into the slot on the base plate and secure it at the desired distance using the locking screw.
5. Operating Instructions
5.1 Power Connection
Connect the jigsaw's power cord to a 220-240V AC power outlet. Ensure the power switch is in the OFF position before connecting.
5.2 Variable Speed Control
The jigsaw features a variable speed trigger, allowing you to adjust the cutting speed based on the material and desired finish. Press the trigger gently for lower speeds and apply more pressure for higher speeds. For continuous operation, press the lock-on button while the trigger is depressed.
5.3 Pendulum Action Adjustment
The 4-stage pendulum action allows for faster cutting in various materials. Adjust the pendulum selector to one of the four settings:
- Setting 0 (No Pendulum Action): For fine, precise cuts in thin materials, plastics, and metals.
- Settings 1-3 (Increasing Pendulum Action): For faster, more aggressive cuts in wood and other soft materials. Higher settings provide faster cutting but may result in a rougher finish.
Experiment with different settings on scrap material to find the optimal setting for your specific task.
5.4 Cutting Techniques
- Mark your cutting line clearly on the workpiece.
- Place the base plate flat on the workpiece, ensuring the blade is clear of the material.
- Start the jigsaw and allow it to reach full speed before engaging the blade with the material.
- Guide the jigsaw along the cutting line with steady, even pressure. Do not force the tool; let the blade do the work.
- For plunge cuts, tilt the jigsaw forward, resting the front edge of the base plate on the workpiece. Start the tool, then slowly lower the blade into the material.
- When finished, release the trigger and wait for the blade to stop completely before lifting the tool from the workpiece.

6. Maintenance
6.1 Cleaning
Regularly clean the ventilation slots of the jigsaw to prevent overheating. Use a soft brush or compressed air to remove dust and debris. Do not use water or chemical cleaners. Wipe the exterior with a damp cloth.
6.2 Blade Care and Replacement
Inspect blades before each use for sharpness and damage. Dull or damaged blades can cause kickback and poor cutting performance. Replace blades as described in Section 4.2 when they become dull or broken. Always use appropriate T-shank blades for your jigsaw.
