Installing Drill Bits and Accessories (Keyless Chuck)
The drill features a 3/8-inch (10mm) keyless chuck for quick and easy bit changes.
- Ensure the drill is off and the forward/reverse switch is in the center (locked) position to prevent accidental starting.
- Grip the rear collar of the chuck with one hand and rotate the front collar counter-clockwise with the other hand until the chuck jaws are open wide enough to insert the bit.
- Insert the desired drill bit or accessory into the chuck jaws. Ensure the bit is inserted as far as possible without touching the chuck body.
- Rotate the front collar clockwise to tighten the chuck jaws firmly around the bit. Hand-tighten until the bit is secure.
- Lati Yọ: Reverse the process by rotating the front collar counter-clockwise.

4. Awọn ọna Liluho
Oniyipada Iyara Iyatọ
The drill features a variable speed trigger, allowing you to control the drilling speed by the amount of pressure applied. Pressing the trigger lightly results in lower speed, while pressing it fully increases the speed up to the maximum setting.
2-Speed Setting
A 2-speed selector switch is located on top of the drill. This allows you to choose between two main speed ranges:
- Ipò 1 (Iyára Kekere): 0-450 RPM. Ideal for driving screws, larger drilling diameters, or applications requiring higher torque and more control.
- Ipò Kejì (Iyára Gíga): 0-1450 RPM. Suitable for faster drilling in softer materials or smaller drilling diameters.
Clutch / Torque Adjustment (18+1 Positions)
The torque adjustment collar, located behind the chuck, allows you to set the amount of torque the drill will apply before the clutch disengages. This prevents over-driving screws or damaging the workpiece. The 18+1 settings include:
- Eto 1-18: For driving screws. Lower numbers are for smaller screws or softer materials; higher numbers are for larger screws or harder materials.
- Drill Symbol (Drill Mode): For drilling applications. This setting bypasses the clutch, providing maximum torque for drilling.
Siwaju / yiyipada Yipada
The forward/reverse switch is located above the trigger. It controls the direction of rotation:
- Ipo Osi: Forward rotation (for drilling and driving screws).
- Ipo ti o tọ: Reverse rotation (for removing screws or backing out bits).
- Center Position: Locks the trigger, preventing accidental starting. Always set to the center position when changing bits, performing maintenance, or storing the tool.

Nọmba 4.1: View of the drill's base, highlighting the magnetic bit holder for convenient storage of small accessories. The forward and reverse rotation mechanism is also illustrated.
Imọlẹ Ise LED
The integrated LED work light automatically illuminates when the trigger is pressed, providing visibility in dimly lit work areas. It remains on for a short period after the trigger is released.

Dimu oofa Bit
A magnetic bit holder is conveniently located on the back of the drill, allowing you to store frequently used drill or driver bits for quick access during tasks.
