3. Operating Instructions

3.1 Selecting and Attaching Bits

1. Identify the correct bit type and size required for your screw. Refer to the markings on the bit slots.
2. Insert the selected bit firmly into the magnetic tip of the screwdriver handle. The magnetic tip will hold the bit securely.

3.2 Using the Handle and Shafts

• Standard Use: Hold the handle firmly and rotate to loosen or tighten screws. The tail cap of the handle is rotatable for comfortable, continuous turning.
• Extendable Shaft: For screws located in deep or recessed areas, pull the tool bar to extend its length. This provides additional reach.
• Flexible Shaft: Attach the universal hose (flexible shaft) between the handle and the bit for accessing screws at awkward angles or in tight spaces.

3.3 Utilizing Multifunctional Accessories

• Magnetic Zones: The case includes magnetic addition and subtraction zones. Use these to magnetize bits for better screw retention or demagnetize them to prevent interference with sensitive electronics.
• Pry Tools: Use the double-ended pry bar and triangular picks to carefully open electronic device casings without causing damage.
• Suction Cup: The suction cup assists in safely lifting screens or panels from devices.
• Tweezers: Precision tweezers are included for handling small components and screws.
• Adapter: A silver adapter is provided for use with electric screwdrivers, allowing compatibility with larger bits if needed.

4. Maintenance

• Cleaning: After each use, wipe down the screwdriver handle and bits with a clean, dry cloth to remove any dust, dirt, or debris. Avoid using harsh chemicals or abrasive materials.
• Storage: Always return all bits and accessories to their designated slots in the storage case. Ensure the case is securely latched to prevent components from falling out or getting lost. Store the set in a dry place away from direct sunlight and extreme temperatures.
• Bit Inspection: Periodically inspect the bits for any signs of wear, damage, or corrosion. Replace any damaged bits to ensure optimal performance and prevent damage to screws.
• Handle Care: Keep the handle clean and free of grease or oil to maintain a secure grip.

5. Troubleshooting

• Bit Not Fitting Screw: Ensure you have selected the correct bit type and size for the screw head. Using an incorrect bit can strip the screw or damage the bit.
• Screws Falling Off Bit: If screws are not adhering to the bit, use the magnetic addition zone on the case to re-magnetize the bit tip.
• Difficulty Reaching Screws: Utilize the extendable shaft for deeper screws or the flexible shaft for screws in awkward positions.
• Small Screws Lost: Always use the magnetic mat to organize and secure small screws during disassembly and reassembly.
• Case Not Closing Properly: Ensure all bits and accessories are correctly placed in their respective slots and that no items are obstructing the closing mechanism.
