Assembly

Installing the Auxiliary Handle
- Remove the battery pack.
- Turn the handle grip counterclockwise to loosen it.
- Place the hooks over the mounting ribs behind the torque adjustment ring.
- Turn the handle grip clockwise to tighten.
Installing/Removing Bits
- Lock the switch trigger.
- Open the chuck jaws until the opening is slightly larger than the bit size.
- Insert the drill bit straight into the chuck jaws.
- Tighten the chuck sleeve securely.
Operation





Variable Speed Switch Trigger
The trigger delivers higher speed with increased pressure and lower speed with decreased pressure. To turn the tool ON, depress the trigger. To turn it OFF, release the trigger.
Direction of Rotation Selector
Set the selector to the left for forward drilling, to the right for reverse, and to the center (OFF) to lock the trigger when not in use.
Two-Speed Gear Train
- Low Speed (1): Use for applications requiring higher power and torque (e.g., driving screws, drilling in metal).
- High Speed (2): Use for fast drilling or driving applications (e.g., wood, masonry, hammer drilling).
Quick Mode Selector
Allows switching between modes:
- Drive Mode: For driving screws.
- Drill Mode: For drilling and heavy-duty applications.
- Hammer Mode: For drilling into masonry and concrete.
Adjusting Torque
Rotate the torque adjustment ring to increase or decrease torque. Higher settings provide more torque for driving larger screws.
Troubleshooting
The drill features an LED light that indicates tool status:
- Solid Light: Normal operation.
- 3 Flashes: Low battery (replace/recharge).
- 6 Flashes: Excessive force (wait 5 seconds).
- 9 Flashes: Over temperature (let tool cool).
