4.1 General Use
This insulated screwdriver is designed for tightening and loosening slotted screws, particularly in electrical applications where protection against electric shock is required.
- Select Correct Size: Ensure the 4.0 mm slotted tip matches the screw head to prevent cam-out and damage to the screw or tool.
- Insert Tip: Place the screwdriver tip firmly into the screw slot.
- Apply Pressure: Apply downward pressure while turning the handle clockwise to tighten or counter-clockwise to loosen. Maintain a firm grip on the SoftFinish handle.
- Electrical Work: When working on live electrical circuits (up to 1,000 V AC), always confirm the circuit is de-energized if possible. If working on live circuits is unavoidable, rely on the VDE insulation and follow all relevant electrical safety protocols.
