Twist the collar back to lock the bit securely in place (Step 4). Always ensure the bit is fully inserted and locked before operation. Do not operate the drill without a bit or with a loose bit.

Operating Instructions
Power On/Off and Speed Adjustment
To power on the device, rotate the Speed Control Knob clockwise. The LED display will illuminate, indicating the current speed. Continue rotating clockwise to increase speed up to 35000 RPM. Rotate counter-clockwise to decrease speed and power off.
Forward/Reverse Rotation
Use the FWD/REV switch to change the rotation direction of the drill bit. Ensure the drill is stopped or at a very low speed before changing direction to prevent damage to the motor.

This image demonstrates the ability to adjust the rotation direction of the drill bit, allowing for both forward and reverse operation. Always change direction when the drill is stopped or at a low speed.

Maintenance
Cleaning
After each use, disconnect the power and gently wipe the handpiece and control unit with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners. Remove any dust or debris from the drill bit chuck.
Storage
Store the nail drill in a dry, cool place away from direct sunlight and moisture. Ensure all bits are removed from the handpiece before storage to prevent damage to the chuck mechanism.
Troubleshooting
Common Issues and Solutions
- Device not powering on: Ensure the device is fully charged. Check the connection between the handpiece and the control unit.
- Bit not rotating: Verify the bit is securely locked in the handpiece. Check if the FWD/REV switch is in a neutral position or if the speed knob is set too low.
- Excessive vibration or noise: Ensure the drill bit is correctly inserted and not bent. A loose bit can cause vibration. If the issue persists, the bit may be damaged and require replacement.
- Overheating: Avoid continuous operation for more than 20 minutes. Allow the device to cool down between extended uses. Ensure proper ventilation around the control unit.
