4.1 Powering On/Off and Speed Control

• The drill is activated by pressing the variable speed trigger switch.
• The speed of the drill is controlled by the amount of pressure applied to the trigger. Pressing lightly results in lower speed, while pressing fully results in maximum speed.
• Release the trigger to turn off the drill.

4.2 Forward/Reverse Rotation

• The forward/reverse selector switch is located above the trigger.
• Push the switch to the left for forward rotation (drilling/driving screws in).
• Push the switch to the right for reverse rotation (removing screws).
• When the switch is in the center position, the trigger is locked, preventing accidental startup.

4.3 Gearbox Speed Selection

• The 2-speed gearbox selector switch is located on top of the drill.
• Position 1 (Low Speed): For high torque applications, such as driving large screws or drilling large holes.
• Position 2 (High Speed): For faster drilling in softer materials or smaller holes.
• Always ensure the drill is stopped before changing gear speeds.

4.4 Torque and Mode Selection

• The torque adjustment ring is located behind the chuck.
• Rotate the ring to select the desired torque setting (1-21) for driving screws. Lower numbers are for smaller screws and softer materials, higher numbers for larger screws and harder materials.
• For drilling into wood or metal, select the drill symbol (drill mode).
• For drilling into masonry or concrete, select the hammer drill symbol (hammer drill mode).

5. Maintenance

5.1 Cleaning

• Regularly clean the ventilation openings on the drill to prevent overheating.
• Use a soft, damp cloth to wipe down the tool's exterior. Do not use harsh chemicals or abrasive cleaners.
