Introduction
This manual provides instructions for the safe and effective use of your VESSEL 910HD-73 NMC-2P Bit Magnetizer/Demagnetizer. This tool is designed to quickly magnetize or demagnetize screwdriver bits, improving efficiency when working with screws and preventing unwanted magnetic interference.
Product Overview
The VESSEL 910HD-73 NMC-2P is a compact and portable device for managing the magnetic properties of screwdriver bits. It is compatible with standard 6.35mm hexagonal shaft bits and 6.4mm round shaft bits, commonly used in precision work.

Operating Instructions
1. Magnetizing a Screwdriver Bit
To magnetize a screwdriver bit, insert the bit into the designated magnetizing slot of the VESSEL NMC-2P unit. Rub the bit back and forth several times against the internal magnets. This process will impart a magnetic charge to the bit, allowing it to hold screws more effectively.

2. Demagnetizing a Screwdriver Bit
To demagnetize a screwdriver bit, insert the bit into the demagnetizing slot of the VESSEL NMC-2P unit. Rub the bit back and forth several times. This action will disrupt the magnetic field of the bit, removing its magnetic properties. Demagnetization is useful when working near sensitive electronic components or when metal shavings are sticking to the bit.

3. Practical Application
Once magnetized, your screwdriver bit will securely hold screws, preventing them from dropping during installation or removal. This is particularly beneficial in tight spaces or when working overhead.

Maintenance
- Keep the magnetizer/demagnetizer clean and free from dust and debris.
- Store in a dry place away from strong magnetic fields to preserve its effectiveness.
- Avoid dropping the unit, as this may damage the internal magnets.
Troubleshooting
If your screwdriver bit does not magnetize or demagnetize effectively:
- Ensure the bit is made of a ferrous material (e.g., steel) that can be magnetized.
- Repeat the magnetizing/demagnetizing process several times, applying firm pressure.
- Check if the tool itself has been exposed to extreme conditions that might have weakened its internal magnets.
