Maintaining and caring for your Bosch PS21-2A 12V Max 2-Speed Pocket Driver is essential to ensure its longevity and optimal performance. Here are some tips to keep your tool in top condition:
- Clean Regularly: After each use, wipe the tool with a clean, dry cloth to remove any dust, debris, or grease. Use a soft brush to clean hard-to-reach areas.
- Check for Damage: Inspect the tool regularly for any signs of wear or damage. Check the chuck, gearbox, and housing for cracks or loose parts. If you notice any issues, have the tool repaired by a professional before using it again.
- Lubricate Moving Parts: Apply a small amount of light machine oil to moving parts, such as the chuck and gearbox, to keep them operating smoothly. Avoid using too much oil, as this can attract dust and debris.
- Store Properly: When not in use, store the tool in a dry, cool place. Avoid exposing it to extreme temperatures or moisture, as this can damage the battery and electronic components.
- Battery Care: To maximize battery life, charge the batteries only when they are fully discharged. Avoid leaving the battery in the charger for extended periods. Store batteries in a cool, dry place and recharge them every few months if not in use.

Practical Tips for Use
To get the most out of your Bosch PS21-2A 12V Max 2-Speed Pocket Driver, consider the following practical tips:
- Select the Right Bit: Always use the correct bit size and type for the screw or material you’re working with. This ensures a snug fit and reduces the risk of stripping the screw head.
- Adjust Speed and Torque: Use the lower speed setting (0-350 RPM) for more control when starting a screw or drilling in delicate materials. Switch to the higher speed setting (0-1,300 RPM) for faster drilling or driving in tougher materials. Adjust the torque setting based on the material’s hardness and the screw size.
- Use the Clutch Settings: The 20+1 clutch settings allow you to precisely control the depth and torque of the screw. Start with a lower setting and increase it until you achieve the desired result without overdriving or stripping the screw.
- Maintain a Steady Grip: Hold the tool firmly with both hands, if possible, to ensure stability and accuracy. Keep your grip comfortable to reduce fatigue during extended use.
- Utilize the LED Light: The built-in LED light illuminates the work area, making it easier to see what you’re doing, especially in dimly lit spaces. Make sure the light is directed towards your work surface.
- Keep Batteries Charged: Always have a spare battery charged and ready to go. This way, you can switch batteries and continue working without interruptions.
- Drill Pilot Holes: For precise screw placement or when working with hardwoods, drill pilot holes slightly smaller than the screw diameter. This makes driving the screw easier and prevents splitting the material.
- Be Mindful of Overheating: If the tool starts to overheat, take a break and let it cool down before continuing. Overheating can damage the motor and reduce the tool’s lifespan.
- Store Bits in the Tool: The Bosch PS21-2A features onboard storage for two bits. Keep your most commonly used bits in these slots for quick access.
- Practice Safety: Always wear appropriate protective gear, such as safety glasses and gloves, when using the tool. Keep your work area clean and well-lit, and be aware of your surroundings to avoid accidents.
