5. Operating Instructions

5.1 Basic Operation

1. Power On: Turn the main power switch on the controller to the "ON" position. The digital speed display will illuminate.
2. Insert Accessory: With the power off or the handpiece stopped, loosen the collet nut on the BH-60 Handpiece. Insert the desired 1/8" shank accessory (e.g., bur, polishing wheel) fully into the collet. Tighten the collet nut securely using the provided wrench.
3. Speed Adjustment:
   • Manual Control: Use the speed control knob on the controller to set the desired RPM. The digital display shows the current speed.
   • Foot Pedal Control: If using the foot rheostat, ensure the controller is set to foot pedal mode (if applicable, refer to controller specific markings). Press the foot pedal to gradually increase speed. Release to decrease.
4. Rotation Direction: Use the forward/reverse switch on the controller to select the desired rotation direction. Change direction only when the handpiece is completely stopped.
5. Begin Work: Apply gentle pressure to the workpiece. Avoid excessive force, which can reduce tool life and performance.
6. Power Off: After use, turn the speed control to minimum, allow the handpiece to stop, then switch the main power to "OFF". Disconnect from the power outlet if storing for extended periods.

5.2 Digital Speed Display

The Handy 700 controller features an easy-to-read digital speed display. This display provides precise feedback on the current rotational speed (RPM) of the handpiece, allowing for accurate and repeatable settings for various applications.

5.3 Variable Speed Control

The system offers variable speed control up to 50,000 RPM. This allows users to match the speed to the specific material and accessory being used, optimizing performance and preventing damage to the workpiece or tool.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your Gesswein Handy 700 system.

• Cleaning:
  • Wipe down the controller and handpiece with a soft, dry cloth after each use.
  • Do not use harsh chemicals or abrasive cleaners.
  • Ensure no dust or debris accumulates in the ventilation openings of the controller.
• Collet Maintenance:
  • Periodically clean the collet and collet nut to remove any accumulated dust or debris.
  • Ensure the collet is free from damage or wear. Replace if necessary to maintain proper grip on accessories.
• Handpiece Care:
  • Avoid dropping or subjecting the handpiece to impact.
  • Do not attempt to disassemble the handpiece beyond routine collet cleaning. Internal repairs should only be performed by qualified service personnel.
