Safety Instructions

When using a micromotor handpiece, it is crucial to follow safety guidelines to prevent serious injury:

1. Eye and Face Protection:
   • Always wear proper eye and face protection when operating the micromotor.
2. Accessories:
   • Use only accessories rated for 50,000 RPM or higher speeds.
   • Inspect each accessory for cracks or flaws before use.
   • Insert the shank or arbor of an accessory or mandrel into the collet or chuck as far as possible for proper support.
3. Operation:
   • Avoid using excessive side pressures that may bend or break the shank or arbor of an accessory.
   • Do not stall the motor by jamming or using excessive pressure on the mounted point, buff, wheel, or accessory.
   • Use a dust collector (vacuum system) to pull sawdust, grinding dust, or other debris away from the work area and the micromotor intake vents.
   • Never operate the handpiece with a damaged power cord.
4. Preparation:
   • Never turn on or start the handpiece while the chuck is in the open (unlocked) position.
   • Ensure a bur is installed and secured in the collet, and the spindle is not locked.

Features of the Brushless Micro Motor

The brushless micro motor comes with several features that enhance its performance and safety:

1. Intelligent Protection Function:
   • The motor has an intelligent protection system that activates in case of no connection to the handpiece, motor damage, controller failure, or high temperature. The display window will flash to indicate protection.
2. Power Supply:
   • Follow the manufacturer’s guidelines for power supply (AC110V or AC220V) to avoid damaging the controller.
3. Troubleshooting:
   • If the machine does not work, check the power cord, handpiece, foot switch, and fuse. Ensure the equipment is not over-temperature before use.
4. Maintenance:
   • Turn off the power switch when the device is not in use.
   • Protect the handpiece, as it is a sophisticated piece of equipment.

Using the Motor Handpiece

To change accessories in the motor handpiece:

1. Turn Off the Motor:
   • Use the Motor On/Off Switch and the Power Switch to turn off the motor.
2. Open the Collet:
   • Twist the Chuck Handle in the “R” or release direction (clockwise) until the raised indicator bar clicks into the far left mark on the silver center ring.
3. Replace the Accessory:
   • Remove the accessory and replace it with another. Insert the new accessory shank fully into the collet for maximum support.
4. Secure the Collet:
   • Twist the knurled Chuck Handle toward the “S” or secure position by turning counter-clockwise until it snaps to lock the collet. The accessory and the collet will be able to spin freely.

Precautions

To ensure safe and effective use of the motor:

1. Power Supply:
   • Follow the manufacturer’s guidelines for power supply to avoid damaging the controller.
2. Inspection:
   • Regularly check the power cord, handpiece, foot switch, and fuse for any issues.
3. Maintenance:
   • Turn off the power switch when the device is not in use.
   • Protect the handpiece from damage.
4. Avoid Interference:
   • Do not use the control for other devices to prevent malfunctions or damage.

By following these guidelines and precautions, you can ensure the safe and effective use of the 50,000 RPM electric micro motor in your dental lab or nail beauty applications.
