The bit holder is magnetic, preventing bits from dropping during changes and ensuring smooth operation. This design is ideal for situations where space is limited, such as working behind appliances or in automotive compartments.

Setup
Inserting and Removing Bits
- Select the appropriate bit for your fastener.
- Insert the bit firmly into the magnetic bit holder at the end of the screwdriver. The magnetic holder will secure the bit in place.
- To remove, simply pull the bit straight out from the holder.
Adjusting Ratchet Direction
The screwdriver features a switch to change the ratcheting direction:
- Locate the small lever on the side of the screwdriver head.
- Push the lever to the + position for tightening (clockwise rotation).
- Push the lever to the - position for loosening (counter-clockwise rotation).
- The middle position locks the ratchet for fixed use.
Operating Instructions
The ultra-low profile design allows the screwdriver to be used in extremely tight spaces where traditional screwdrivers cannot fit. Its thin body (2.4mm) and offset head provide unparalleled access.

To use, place the bit onto the fastener head. Apply downward pressure on the handle and rotate the screwdriver in the desired direction. The ratcheting mechanism will allow you to turn the fastener with minimal wrist movement, reducing fatigue and increasing efficiency.

Maintenance
- Clean the screwdriver and bits after each use to remove dirt, grease, or debris. Use a soft, dry cloth.
- Store the tool and bits in a dry environment to prevent rust and corrosion.
- Avoid using abrasive cleaners or solvents that could damage the finish.
- Periodically check bits for wear and replace as necessary to ensure optimal performance and prevent fastener damage.
Troubleshooting
Bit not holding securely:
Ensure the bit is fully inserted into the magnetic holder. If the issue persists, the bit or holder magnet may be worn and require replacement.
Rachet mechanism not engaging:
Check that the direction switch is fully engaged in either the + or - position, not in the neutral (locked) position.
Difficulty turning fasteners:
Verify that the correct bit size and type are being used for the fastener. Ensure sufficient downward pressure is applied to prevent cam-out and stripping of the fastener head.
