How to use

Charge the battery fully before first use, then fit the appropriate screwdriver bit into the chuck or bit holder. Select the required torque setting if the tool provides adjustable torque, position the bit on the screw head and apply steady pressure while engaging the trigger. For driving screws, start at low speed to seat the screw and increase speed as needed. For small drilling tasks, use appropriate bits and steady, controlled pressure. After use, switch the tool off, remove the bit if needed and store with the battery removed or in a charged state according to the battery manufacturer's guidance.

Recommendations

Use suitable screwdriver bits for the screw types to prevent cam‑out. When working on delicate materials, reduce torque or use a clutch setting to avoid over‑driving screws. Keep the ventilation openings free of dust and debris, store the battery at moderate temperature and follow standard safety practices including eye protection and secure workpiece clamping.
