5. Operating Instructions

5.1 Selecting Speed and Torque

• Speed Selection: Use the speed selector switch on top of the drill.
  • Position 1 (Low Speed): 0-750 RPM, ideal for high-torque applications like driving screws or drilling large holes.
  • Position 2 (High Speed): 0-1350 RPM, suitable for fast drilling in softer materials.
• Torque Adjustment: Rotate the torque adjustment collar to select the desired torque setting (1-20) or drill mode.
  • Settings 1-20: Lower numbers for smaller screws or softer materials; higher numbers for larger screws or harder materials.
  • Drill Mode (Drill Icon): For drilling applications, bypasses the clutch for maximum torque.
