3. Operating Instructions

Follow these guidelines for safe and effective operation of your Wiha Hex Screwdriver.

General Usage:

• Select Correct Size: Always match the hex screwdriver size (4.0mm for this model) to the corresponding hex socket screw. Using an incorrect size can damage both the tool and the fastener.
• Insert Fully: Ensure the hex tip is fully seated into the screw head to prevent stripping.
• Apply Pressure: Apply firm, steady pressure along the axis of the screw while turning to prevent cam-out.
• Turning: Rotate the T-handle clockwise to tighten and counter-clockwise to loosen screws. The T-handle design allows for greater leverage and comfortable application of torque.
• Avoid Over-tightening: Tighten screws only to the required specification. Over-tightening can damage the screw, the material, or the tool.

Safety Precautions:

• Always wear appropriate personal protective equipment, such as safety glasses, when using hand tools.
• Do not use the screwdriver as a pry bar, chisel, or punch.
• Do not strike the handle or shaft with a hammer or other object.
• Keep hands clear of moving parts and sharp edges.
• Store the tool safely when not in use to prevent injury or damage.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your Wiha Hex Screwdriver.

Cleaning:

• Wipe the tool clean with a dry or slightly damp cloth after each use to remove dirt, grease, or debris.
• Avoid using harsh chemicals or abrasive cleaners, which can damage the finish or material.

Storage:

• Store the screwdriver in a dry environment to prevent rust or corrosion.
• Keep it away from direct sunlight and extreme temperatures.
• Store in a tool box or on a tool rack to protect the tip from damage and prevent accidental injury.

Inspection:

• Periodically inspect the hex tip for signs of wear, rounding, or damage. A worn tip can strip screw heads.
• Check the shaft for any bends or cracks.
• Ensure the handle remains firm and undamaged.
• Replace the tool if significant wear or damage is detected to ensure safety and effectiveness.

5. Troubleshooting

This section addresses common issues you might encounter while using your hex screwdriver.

Issue: Screwdriver slips or strips screw head.
