- Speed 1 (Low): For high torque applications, driving fasteners, or drilling large diameter holes.
- Speed 2 (Medium): For general drilling and fastening.
- Speed 3 (High): For high-speed drilling in smaller diameters.
- Drill Mode: For drilling in wood, metal, and plastics.
- Hammer Drill Mode: For drilling in masonry and concrete.

4.2 Installing Drill Bits/Accessories
To install a drill bit or accessory, twist the chuck counter-clockwise to open the jaws. Insert the bit fully into the chuck and then twist clockwise to tighten securely. Ensure the bit is centered and firmly gripped before operation.
4.3 Using the LED Work Light
The integrated LED light can be activated by pressing the button near the base of the handle. It features a 3-position pivot to direct light where needed, improving visibility in dark work areas. The light can also be set to a 20-minute timer for use as a work light.
4.4 ANTI-ROTATION System
The PERFORM & PROTECT ANTI-ROTATION system is a safety feature that senses the rotational motion of the tool. If the tool binds up and experiences excessive rotation, the system will automatically shut it down to prevent injury. This system is particularly useful in high-torque situations where kickback can occur.
