How to use

Select the screwdriver when working with slotted screws that match the 4 mm blade width. Hold the insulated handle firmly with a straight wrist to align the blade with the screw slot, then apply steady rotational force to fasten or loosen the screw. For electrical work, ensure the circuit is de-energized whenever possible and follow local safety procedures. Inspect the blade before use for signs of wear or damage and replace the tool if the tip is deformed to maintain accurate engagement with screw heads.

Recommendations

Use the tool within its intended manual torque limits and avoid applying excessive force with cheater bars or impact methods. For live electrical work, use only approved insulated tools and verify insulation integrity regularly. Store the screwdriver in a dry toolbox or holder to prevent corrosion and keep the blade tip clean for precise contact with screw heads.
