To start the saw, simultaneously press the safety switch (usually a small button near the handle) and then squeeze the main trigger switch. To turn off, release the trigger switch.
6.2 Axuste da profundidade de corte
The cutting depth can be adjusted to suit the thickness of your material. Loosen the depth adjustment knob, set the desired depth, and then tighten the knob securely.
- Maximum cutting depth at 90°: 1-11/16" (42.8mm)
- Maximum cutting depth at 45°: 1-1/8" (28mm)
6.3 Adjusting Bevel Angle (0-45°)
For angled cuts, adjust the bevel angle. Loosen the bevel adjustment knob, tilt the base plate to the desired angle between 0 and 45 degrees, and then tighten the knob firmly.

Figure 6.1: The ALEAPOW K4 allows for 0-45 degree bevel cutting, with a maximum cutting depth of 1-1/8 inches at 45 degrees.
6.4 Uso da guía láser
The integrated laser guide projects a red line onto your workpiece, assisting in maintaining a straight cutting path. Align the laser line with your marked cut line for increased precision.

Figure 6.2: The adjustable laser guide and scale ruler provide enhanced precision for straight cuts, ensuring accuracy during operation.
6.5 Técnicas de corte
Always ensure the blade is spinning at full speed before engaging with the material. Apply steady, even pressure and allow the saw to do the work. Avoid forcing the saw through the material, as this can lead to kickback or damage to the tool/blade.
