Common questions about manuals, registration, and support for this brand.
No. Do not clean your grinder with water. It is recommended to use a brush and air blower to clean the burrs and internal components to prevent rust and damage.
To calibrate, tighten the adjustment dial counter-clockwise to the zero point (where resistance is felt). If the indicator does not align with '0', loosen the knurled thumb nut, adjust the dial ring to '0', and then retighten the nut while pressing the burr.
If the burrs become stuck, do not force the handle. Instead, loosen the adjustment dial ring and press the central shaft down to release the tension before attempting to operate it again.
Turn the adjustment dial ring to change the grind size. Typically, rotating counter-clockwise produces a finer grind, while rotating clockwise produces a coarser grind, depending on your specific model's design.
