REGULATION OF THE BURR
To adjust grinding fineness, it is necessary to use the knob
(10)
, turning it clockwise for finer grinding or anti-clockwise for
a coarser burr. This adjustment does not have any stop points
and each turn of the knob corresponds to a movement of 0.4
mm of the burrs. The adjustment is carried out freely and, at
every turn of the knob, the burrs move of approximately 0.4
mm.
Grinding fineness is factory set, with the burrs first adjusted
so that they touch each other (0) and then moving the burrs
so that they are at a distance to provide an average grinding
fineness for espresso coffee. Burrs with re-settable adjust-
ment knob can be set to zero at an established grinding point
by holding the top part of the knob in position and using the
ring nut on the base of the knob itself.
Caution: grinding fineness adjustment needs to be performed gradually, grinding a little cof-
fee each time that the knob is turned by two numbers (notches).
The machine may seize up if the knob is moved by one turn while the motor is switched off.
