5. Operating Instructions

5.1 Speed Selection

Figure 5.1: Top view of the drill, illustrating the two-speed selector switch. The switch can be set to '1' for low speed/high torque or '2' for high speed/low torque.

The tool has a two-speed mechanical gear selection. Use the speed selector switch located on top of the tool.

• Position '1': Low speed (0-600 RPM) for heavy-duty applications, large diameter drilling, or driving large screws where high torque is required.
• Position '2': High speed (0-1900 RPM) for light-duty applications, small diameter drilling, or fast driving where speed is prioritized.

Always ensure the tool is completely stopped before changing the speed setting.

5.2 Clutch Settings and Drilling Mode

Figure 5.2: A detailed view of the drill's chuck and the adjustable clutch ring. The numbers on the clutch ring indicate different torque settings, and the drill symbol represents the drilling mode.

The clutch ring allows you to select from 22 torque settings for driving screws, plus a dedicated drilling mode.

• Torque Settings (1-22): Rotate the clutch ring to the desired number. Lower numbers are for smaller screws or softer materials, while higher numbers are for larger screws or harder materials. The clutch will disengage when the set torque is reached, preventing overtightening or stripping.
• Drilling Mode (Drill Symbol): Rotate the clutch ring to the drill symbol for drilling operations. In this mode, the clutch does not engage, providing maximum torque for drilling.

5.3 Trigger Switch and Forward/Reverse

Figure 5.3: A close-up image showing the variable speed trigger and the forward/reverse rotation selector lever. The lever is positioned above the trigger for easy access.

• Trigger Switch: The tool speed is controlled by the amount of pressure applied to the trigger switch. Pressing the trigger further increases the speed.
• Forward/Reverse Lever: Push the lever from the left side for forward rotation (drilling/driving). Push it from the right side for reverse rotation (removing screws). Center the lever to lock the trigger and prevent accidental startup.

5.4 LED Job Light

Figure 5.4: The LED job light activated, casting illumination on the area directly in front of the drill chuck. This feature aids visibility in dimly lit workspaces.

The twin LED job lights automatically illuminate when the trigger is pulled, providing visibility in dark work areas. They feature pre-glow and after-glow functions, staying on briefly after the trigger is released.

5.5 Battery Protection System

The tool is equipped with a battery protection system that automatically cuts off power to extend battery life. This system protects against over-discharge, temperature, and circuit overload.
