Introduction

This tutorial will guide you through the process of resetting the potentiometer on the foot pedal of NIDEC-SHIMPO’s VL-WHISPER, VL-LITE, and ASPIRE-FP pottery wheels. Properly resetting the potentiometer ensures that your pottery wheel responds accurately when using the foot pedal, allowing for better control during your pottery work.

Step 1: Gather Required Tools

Before starting, make sure you have the following tools on hand:

  • A 4 mm Allen wrench
  • A number 1 Phillips screwdriver

Having these tools ready will streamline the resetting process.

Step 2: Inspect the Foot Pedal

  • Examine the foot pedal in its stop position, where the heel touches the base. In this position, the wheel head should not spin.
  • When you press on the toe of the foot pedal, the wheel should start spinning. If it does not, a reset is necessary.

Step 3: Access the Potentiometer

  • Turn the foot pedal over.
  • Use your Phillips screwdriver to unscrew the rubber feet holding the back plate.
  • Remove the back plate to expose the internal components.

Step 4: Loosen the Potentiometer Mounting Bracket

  • Locate the two black socket head cap screws that secure the potentiometer mounting bracket to the foot pedal housing.
  • Use the 4 mm Allen wrench to loosen these screws.

Step 5: Separate the Gears

  • Gently pull back the potentiometer mounting bracket to separate the potentiometer gear from the white nylon gear.
  • This separation is crucial for the reset process.

Step 6: Reset the Potentiometer Gear

  • Start turning the potentiometer gear back and forth until the wheel head starts spinning.
  • This may require several attempts, so ensure you can see the wheel head during this process.
  • Once the wheel head is synced with the potentiometer, bring both gears back to the stop position.

Step 7: Test the Connection

  • Push down on the potentiometer mounting bracket while aligning the potentiometer gear back to the white nylon gear.
  • Tighten one of the socket head cap screws to secure the connection temporarily.
  • Test the foot pedal to see if the wheel head starts spinning simultaneously. If it doesn’t, you may need to repeat the adjustment.

Step 8: Finalize the Adjustment

  • If the adjustment was successful, tighten the second socket head cap screw.
  • Reattach the back plate and screw in the rubber feet to complete the process.

Conclusion

You have successfully reset the potentiometer on your pottery wheel's foot pedal. This process can significantly improve how your wheel responds to your foot pedal inputs. For further enhancement, check out additional tutorials on fine-tuning your potentiometer settings. Happy potting!
