a) The chamber must be halfway filled with the material.

b) Close the washer lid.

 c) Switch on the grinder.

Please notice that you switch off the grinder every five seconds to let it pulverize the materials and then restart it. This process should be done three times in a raw to have finer materials.

If the breaker trips:

a) let the engine cool down and then press the ON button.

b) make sure that you have hit the OFF button to switch the grinder off. Othewise, the next time you plug it in, the grinder will operate unexpectedly.

Do not wash the grinder with water; you can clean it with a damp cloth or a brush.

There are two charcoals mounted at the bottom of the grinder. If they spark, do not worry. Just replace them.

Note: the less material you pour into the chamber, the faster the grinder pulverizes.
