Setup Guide

1
Charge the battery pack
Insert the battery into the charger and plug in. Charge fully before first use — most packs take 1–3 hours. The LED will turn green when complete.
2
Insert the correct bit or blade
Open the chuck by turning it counterclockwise. Insert the drill bit or screwdriver tip and tighten the chuck firmly by hand.
3
Set direction and speed
Use the forward/reverse switch to set rotation direction. Select the speed mode (low for screwing, high for drilling) if your model has multiple speeds.
4
Adjust the clutch
Set the clutch to a low number for driving screws (prevents over-tightening) or to the drill symbol for drilling holes.
5
Use safely
Always wear safety glasses. Keep the drill perpendicular to the surface. Apply steady pressure — let the tool do the work.
