5.2 Mode Selection

The drill features a rapid mode selection collar located behind the chuck. Rotate this collar to choose between three operating modes:

• Drilling Mode (Drill Icon): For general drilling in wood, metal, and plastic.
• Hammer Drilling Mode (Hammer Icon): For drilling into masonry and concrete.
• Driving Mode (Screw Icon): For driving screws, utilizing the clutch settings.

5.3 Torque Settings (Driving Mode Only)

When in driving mode, adjust the torque collar (numbered 1-20) to select the desired torque level. Lower numbers provide less torque, suitable for smaller fasteners or softer materials, preventing overtightening or stripping. Higher numbers provide more torque for larger fasteners or harder materials.

5.4 Speed Selection

The drill has a two-speed gearbox. Use the speed selector switch, typically located on top of the drill, to choose between:

• Speed 1 (Low Speed): 0-460 rpm, ideal for high-torque driving applications and larger drilling diameters.
• Speed 2 (High Speed): 0-1,800 rpm, suitable for high-speed drilling and smaller drilling diameters.

5.5 Operating the Trigger and Direction Switch

• Trigger: Squeeze the trigger to start the drill. The variable speed trigger allows for precise speed control; press lightly for slower speeds and harder for faster speeds.
• Direction Switch: Located above the trigger, this switch controls the rotation direction (forward/reverse) and locks the trigger when in the center position.
