2.1 Work Area Safety
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

5.3 Installing and Removing Drill/Screwdriver Bits
- To Install: Rotate the chuck counter-clockwise to open the jaws. Insert the desired bit into the chuck as far as it will go. Rotate the chuck clockwise to tighten the jaws firmly around the bit.
- To Remove: Rotate the chuck counter-clockwise to loosen the jaws and pull the bit out.
Ensure the bit is securely fastened to prevent it from slipping during operation.

6. Operating Instructions
6.1 Powering On/Off and Speed Control
- To turn the tool ON, press the trigger switch. The speed is variable; press the trigger further for higher speed.
- To turn the tool OFF, release the trigger switch.
- The integrated LED work light will illuminate when the trigger is pressed, providing visibility in dimly lit areas.
6.2 Forward/Reverse Rotation
The forward/reverse selector switch is located above the trigger. Push it to the left for forward rotation (for screwdriving and drilling) and to the right for reverse rotation (for removing screws or freeing jammed bits). Ensure the tool is stopped before changing direction.
6.3 Speed Gear Selection
The drill features a 2-speed gear selector switch on top of the tool:
- Gear 1 (Low Speed, 0-650 RPM): Ideal for high-torque applications like driving large screws or drilling large holes.
- Gear 2 (High Speed, 0-1850 RPM): Suitable for fast drilling in softer materials and smaller diameter holes.
Always select the appropriate gear for the task. Change gears only when the tool is completely stopped.

6.4 Torque Adjustment and Mode Selection
The torque adjustment ring allows you to set the desired torque for screwdriving applications, preventing overtightening or stripping screws. The mode selector ring allows you to switch between different operating modes.
- Screwdriving Mode (Torque Settings 1-35): Use these settings to match the torque to the screw size and material. Lower numbers for smaller screws/softer materials, higher numbers for larger screws/harder materials.
- Drilling Mode (Drill Bit Icon): For general drilling without impact. The clutch is disengaged, providing maximum torque.
- Impact Drilling Mode (Hammer Icon): For drilling into masonry or concrete, providing a hammering action in addition to rotation.
The drill offers 35+3 settings, including 35 torque settings for screwdriving and 3 modes (screwdriving, drilling, impact drilling).
