4. Operating Instructions
Using the KTC PD-2 screwdriver effectively involves applying the correct technique and selecting the appropriate size.
4.1. Basic Operation
The fundamental method for using a screwdriver is to apply pressure while turning. For Phillips head screws, it is crucial to apply significant downward force to prevent cam-out (where the screwdriver slips out of the screw head). The ideal ratio of pushing force to turning force is approximately 7:3. When loosening a tightly fastened screw, increase the pushing force.

4.2. Selecting the Correct Size
It is essential to select a screwdriver size that perfectly matches the screw head. The best practice is to start with a screwdriver that appears slightly larger than the screw head and then try a smaller size if it does not fit. If the screwdriver tip is too large, it will not fit into the screw head. If it is too small, there will be excessive play, which can damage the screw head. The KTC PD-2 is a No.2 Phillips head screwdriver, suitable for common No.2 Phillips screws.
4.3. Penetrating Type Feature
The PD-2 is a "Cross Penetrating Type" screwdriver. This design allows for the application of impact force (e.g., by striking the end of the handle with a hammer) to loosen extremely tight or rusted screws. While this feature is useful, repeated heavy impacts can shorten the tool's lifespan. Use this feature judiciously.
5. Maintenance
Proper maintenance ensures the longevity and performance of your KTC PD-2 screwdriver.
- Cleaning: Wipe the shaft and tip clean after each use to remove dirt, grease, or debris. The wooden handle can be wiped with a dry or slightly damp cloth. Avoid harsh chemicals that may damage the wood.
- Storage: Store the screwdriver in a dry place to prevent rust on the metal parts and to protect the wooden handle from moisture damage.
- Inspection: Regularly inspect the tip for wear, chipping, or bending. A damaged tip can strip screw heads. If the tip is significantly worn, consider replacing the screwdriver.
- Handle Care: The wooden handle offers a warm feel and good grip. While durable, avoid exposing it to extreme temperatures or prolonged moisture to prevent cracking or warping.
6. Safety Precautions
Always observe the following safety precautions when using the KTC PD-2 screwdriver to prevent injury or damage to the tool or workpiece.

- ⚠
WARNING: Do not use this screwdriver on live electrical circuits. The handle is not insulated for electrical work.
- ⓘ
CAUTION: Do not work in an unstable position while holding the workpiece with one hand and the screwdriver with the other. Ensure a stable work environment.
- ⓘ
CAUTION: Do not strike the screwdriver with a hammer unless it is a penetrating type designed for impact (like the PD-2, but use judiciously). Do not use it as a pry bar or chisel.
- ⓘ
CAUTION: Always use a screwdriver that matches the size of the screw head. Using the wrong size can damage the screw or the tool.
- ⓘ
CAUTION: Wear appropriate eye protection (safety glasses) when using hand tools to protect against flying debris.
- ⓘ
CAUTION: Do not use screwdrivers with worn, chipped, or bent tips. This can lead to cam-out and potential injury.
7. Troubleshooting
Screwdrivers are simple tools, but issues can arise from improper use or tool condition.
- Screwdriver slips out of screw head (Cam-out):
- Ensure you are using the correct size Phillips head screwdriver (PD-2 is No.2).
- Apply sufficient downward pressure while turning.
- Check if the screw head is stripped or damaged.
- Inspect the screwdriver tip for wear; a worn tip will not grip properly.
- Screw is too tight to turn:
- Apply more downward pressure.
- For extremely tight screws, utilize the penetrating feature by gently striking the end of the handle with a hammer while applying turning force.
- Consider using a penetrating oil on rusted screws.
- Screwdriver tip is damaged:
- Avoid using the screwdriver as a pry bar or chisel.
- Ensure the tip size matches the screw head to prevent excessive stress.
- If the tip is significantly damaged, the screwdriver should be replaced.
