How to use

Fit an appropriate drill or screwdriver bit into the 1.3 cm chuck and tighten securely before operation. Select the desired speed setting according to the material and task, and use the forward/reverse switch to drive or remove fasteners. Position the drill perpendicular to the work surface for straight holes and apply steady, even pressure while allowing the tool to reach working speed. For repeated work, monitor battery charge and replace or recharge batteries as required to maintain consistent performance.

Recommendations

Use drill bits and screwdriver bits that match the chuck diameter and the material being worked. For wood drilling up to 3.5 cm, start with a lower speed and increase if necessary. Wear appropriate personal protective equipment, such as safety glasses and hearing protection, and follow battery handling and charging guidelines from the battery manufacturer.
