6. Operating Instructions
6.1 Selecting Torque Settings
The torque collar has 22 positions. Rotate the collar to select the desired torque. Lower settings are for driving small screws or working with soft materials, while higher settings are for larger screws or harder materials. The drill icon setting bypasses the clutch for maximum torque in drilling applications.
6.2 Selecting Speed
The drill features a 2-speed transmission:
- Speed 1 (Low): 0-350 RPM, for high torque applications like driving screws or drilling large holes.
- Speed 2 (High): 0-1500 RPM, for fast drilling in wood or metal.
Use the speed selector switch on top of the drill to choose between Speed 1 and Speed 2.
6.3 Selecting Mode (Drill/Hammer Drill)
Rotate the mode selector ring to choose between standard drilling and hammer drilling. Use hammer drill mode for masonry and concrete applications.
6.4 Using the LED Light
The integrated LED light automatically activates when the trigger is pressed, providing improved visibility in dark or confined work areas.
Figure 5: The drill includes an LED light for enhanced visibility.
6.5 Drilling Techniques
- Always hold the drill firmly with both hands, especially during hammer drilling.
- Apply steady, even pressure. Do not force the drill.
- For metal drilling, use a center punch to mark the hole and start with a small pilot hole.
- For masonry, use carbide-tipped bits and the hammer drill function.
