DO NOT FORCE THE ADJUSTMENT PAST THE END STOPS!

Контекст:

With high torque settings, this brake can loosen self-tighten shaft mounted cutting tools. Be certain that tool arbor is keyed, double nutted, or locked very tightly. Test locking mechanism for secure operation periodically.
These controls are single turn potentiometers, which can be set by means of a small screwdriver (An insulated screwdriver is recommended). Both controls are at their minimum when turned fully counter clockwise.

Заранее спасибо.
