5. Operating Instructions
5.1. Powering On/Off and Speed Control
The tool is activated by pressing the trigger switch. The speed is variable and controlled by the amount of pressure applied to the trigger. Releasing the trigger turns the tool off.
5.2. Speed Selection
Use the speed selector switch located on top of the tool to choose between two speed ranges:
- Position 1 (Low Speed): 0-400 RPM, suitable for screwdriving and drilling larger holes.
- Position 2 (High Speed): 0-1500 RPM, suitable for drilling smaller holes and faster operation.
5.3. Torque Adjustment
The torque adjustment collar allows you to select from 20 torque settings plus a drill mode. This prevents overtightening screws and damaging materials.
- Settings 1-20: For screwdriving. Start with a lower setting and increase as needed until the desired screw depth is achieved without stripping the screw head.
- Drill Symbol: For drilling applications, providing maximum torque.
5.4. Forward/Reverse Operation
The forward/reverse switch controls the direction of rotation. Push the switch to the left for forward rotation (drilling/driving screws in) and to the right for reverse rotation (removing screws).
5.5. LED Work Light
The integrated LED light automatically illuminates the work area when the trigger is pressed, improving visibility in dimly lit spaces.
6. Maintenance
