5. Operating Instructions
5.1 Powering On/Off and Continuous Use
- To start the tool, press the trigger switch.
- To stop the tool, release the trigger switch.
- For continuous operation, press the trigger switch and then press the continuous use button. To stop, press the trigger switch again.
5.2 Speed Control
The 6-level speed regulator allows you to match the cutting speed to the material and blade type. Rotate the dial to select the desired speed. Lower speeds are suitable for harder materials like metal, while higher speeds are for softer materials like wood.
5.3 Pendulum Action Control
The jig saw features a 4-position pendulum action control. This mechanism adjusts the orbital motion of the blade. Higher pendulum settings (e.g., position 4) provide faster, more aggressive cuts, ideal for rough cutting in wood. Lower settings (e.g., position 1 or 0 for no pendulum action) are for finer cuts in wood, plastic, or metal, where precision is critical.
5.4 Cutting Materials and Capacities
This jig saw is suitable for cutting wood, plastic, and steel. Refer to the specifications for maximum cutting capacities:
- Wood: Up to 100 mm (approximately 4 inches)
- Metal/Steel: Up to 0.39 inches (approximately 10 mm)
Always use the appropriate blade for the material being cut.
