5. Operating Instructions

5.1 Selecting Operating Mode

Use the mode selector ring (usually located behind the chuck) to choose the appropriate mode:

• Screwdriving Mode: For driving screws. Set the torque adjustment ring to the desired clutch setting (1-X). The clutch will disengage when the set torque is reached, preventing overtightening.
• Drill Mode: For drilling into wood, plastic, or metal. Set the torque adjustment ring to the drill symbol. The clutch will not engage in this mode, providing maximum torque.
• Impact Drill Mode: For drilling into masonry or concrete. Set the torque adjustment ring to the impact drill symbol. This mode combines rotation with a hammering action.

5.2 Selecting Speed

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

• Speed 1 (Low Speed): For high torque applications like driving large screws or drilling large holes. (0-400 RPM)
• Speed 2 (High Speed): For faster drilling of smaller holes or general drilling tasks. (0-1600 RPM)

5.3 Forward/Reverse Rotation

The forward/reverse switch (located above the trigger) controls the direction of rotation:

• Push left for Forward rotation (for drilling and driving screws).
• Push right for Reverse rotation (for removing screws or freeing jammed bits).
• Center position locks the trigger for safety during bit changes or storage.

5.4 Starting and Stopping

• To Start: Squeeze the trigger switch. The speed is variable depending on how far you press the trigger.
• To Stop: Release the trigger switch.

5.5 LED Work Light

The integrated LED work light will illuminate automatically when the trigger is pressed, providing better visibility in dimly lit areas.
