5. Operation

5.1 Variable Speed Trigger

• The drill features a variable speed trigger. Pressing the trigger further increases the speed.
• Release the trigger to stop the drill.

5.2 Speed Gear Selection

The drill has two speed settings, selected via a switch on top of the drill:

• Gear 1 (Low Speed: 0-350 RPM): Ideal for driving screws and applications requiring higher torque and more control.
• Gear 2 (High Speed: 0-1350 RPM): Suitable for drilling and applications requiring faster rotation.

Figure 5.1: The drill's 2-speed transmission allows for optimal performance whether driving screws at low RPM or drilling at high RPM.

5.3 Torque Adjustment (Clutch Settings)

The 18+1 position torque adjustment ring allows you to select the appropriate torque setting for different materials and screw sizes. The 'drill' icon setting bypasses the clutch for maximum torque for drilling applications.

• Settings 1-4: For driving small screws into soft material.
• Settings 5-9: For driving screws into soft material.
• Settings 10-13: For driving screws into soft and hard material.
• Settings 14-16: For driving screws into hard wood.
• Settings 17-18: For driving larger screws.
• Drill Icon: For drilling operations, providing maximum torque without clutch slippage.
