5. Operating Instructions

5.1 Powering On/Off and Variable Speed

The tool is activated by pressing the multi-grip trigger. The speed is variable, meaning the harder you press the trigger, the faster the drill will operate. Release the trigger to turn the tool off.

5.2 Speed Selection

Use the speed selector switch (located on top of the tool) to choose between two speed ranges:

• Speed 1 (Low): 0-650 RPM, ideal for high-torque applications and larger diameter drilling.
• Speed 2 (High): 0-2000 RPM, suitable for faster drilling and driving smaller fasteners.

5.3 Forward/Reverse Control

The forward/reverse switch is located above the trigger. Push it to the left for forward rotation (drilling/driving) and to the right for reverse rotation (removing screws/bits).

5.4 LED Work Light

The integrated LED work light automatically activates when the trigger is pressed, illuminating the work surface for improved visibility in dimly lit areas.

5.5 Using in Tight Spaces

The primary advantage of the DCD740B is its right-angle design, allowing it to fit into confined areas where standard drills cannot. Its compact front-to-back length (4.0") is specifically engineered for this purpose.
