Desolder the power leads from the switch block. Remove the three long bolts securing the motor to the chassis suspension. Reassemble the bottom cap, add fresh high-viscosity spindle
Often overlooked, the stepped pulley must spin freely. The manual explains how to lubricate this crucial part to prevent speed fluctuations. 5. Speed Adjustment and Suspension
Reinstall the motor. The manual states a 30-minute warm-up period before making final speed adjustments. Use the strobe disc. Adjust the eddy current brake until the strobe marks appear stationary at 33.33 RPM.
