4. Setup

Follow these steps to properly set up your flexible shaft with a compatible rotary tool:

1. Ensure Power Off: Disconnect your rotary tool from the power supply before beginning installation.
2. Prepare Rotary Tool: Refer to your rotary tool's instruction manual for specific guidance on attaching flexible shafts. Typically, you will need to remove any existing collet nut or accessory from the rotary tool's spindle.
3. Attach Drive End: Insert the drive end of the flexible shaft into the rotary tool's spindle. Ensure it is fully seated and securely fastened according to your rotary tool's instructions. Some tools may require a specific adapter or collar.
4. Insert Accessory:
   • Loosen the quick-release chuck on the flexible shaft handpiece by rotating the collar counter-clockwise.
   • Insert the shank of your desired accessory (e.g., drill bit, grinding stone) into the chuck. Ensure the shank is inserted as far as possible without bottoming out.
   • Tighten the chuck by rotating the collar clockwise until the accessory is firmly secured. Do not overtighten.
   • Gently pull on the accessory to confirm it is securely held and will not slip during operation.
5. Positioning: Lay the flexible shaft in a gentle curve, avoiding sharp bends or kinks, which can cause excessive wear or damage.

5. Operating Instructions

Once the flexible shaft is properly set up, follow these guidelines for effective and safe operation:

1. Power On: Connect your rotary tool to the power supply.
2. Start at Low Speed: Begin operation at a low speed setting on your rotary tool. Gradually increase the speed as needed for the task and accessory, ensuring not to exceed the maximum 25,000 RPM for the flexible shaft or the accessory's rated speed.
3. Maintain Control: Hold the handpiece firmly with one hand, guiding the accessory to the workpiece. Use your other hand to support the flexible shaft if necessary, ensuring it remains in a gentle curve.
4. Apply Gentle Pressure: Allow the accessory to do the work. Excessive pressure can lead to overheating, reduced performance, and premature wear of both the accessory and the flexible shaft.
5. Avoid Overloading: Do not attempt to perform tasks that require excessive torque or force, as this can damage the flexible shaft or your rotary tool.
6. Intermittent Use: For prolonged operations, allow the tool to cool periodically to prevent overheating.
7. Finish Work: Once the task is complete, turn off the rotary tool and wait for all rotating parts to come to a complete stop before setting the tool down or changing accessories.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your PROXXON flexible shaft:

• Cleaning: After each use, wipe down the exterior of the flexible shaft and handpiece with a clean, dry cloth. Remove any dust or debris from the chuck mechanism. Do not use harsh chemicals or solvents.
• Lubrication: Periodically, the inner flexible shaft may require lubrication. This can typically be done by carefully unscrewing the handpiece and the drive end from the flexible casing, pulling out the inner shaft, and applying a thin layer of light machine oil or grease along its length. Reassemble carefully, ensuring all connections are secure. Refer to the manufacturer's guidelines for specific lubrication intervals and types.
• Inspection: Regularly inspect the flexible shaft for any signs of wear, cracks, or damage to the outer casing. Check the chuck for proper gripping action and ensure the bearings in the handpiece and drive end are smooth and free of play.
• Storage: Store the flexible shaft in a clean, dry place, ideally coiled loosely to avoid sharp bends. Protect it from extreme temperatures and direct sunlight.
