Defect

Grinder rotates 

but without 

grinding.

Cause

Carrier breakage.

Incorrect sense of 

rotation.

incoming fl ow 

of material to be 

ground.

Remedy

Remove the grinder casing cov-

er, take out the broken pieces 

of the driver, insert a new driver 

and then install the grinder cas-

ing cover again.

Have the polarity checked by 

specialised personnel. 

Clean the hopper magnet.

8. Grind Adjustment

The grinder has been precisely adjusted by the manufacturer. However, 

if the ground material is no longer fi ne enough after a longer period, the 

grinder must then be re-adjusted according to the following procedure:

1.  Use a screwdriver to unscrew the fastening screw in the middle of 

the rotary knob and remove the rotary knob.

2.  Switch on the grinder.

3.  Then rotate the exposed adjusting spindle (see Fig. below) very 

carefully and slowly in clockwise direction until a slight rattling 

noise (contact of the grinding disks) can be heard and then rotate 

the adjusting spindle immediately back again in antic lock wise di-

rection.  Attention: The discs must not touch each other!

4.  A grinding test run, now to be carried out is supposed to result in 

fi ne-gritty grain. If the ground material is too fi ne, it can get stuck to 

the grinding mechanism so that the material to be ground can no 

longer continue to descend into the grinding mechanism!

It is important to ensure that no „rattling“ noise of 

the grinding disks can be heard! Their service life will 

otherwise be signifi cantly reduced!

5.  If the adjustment you have made does not fulfi l your expectations, 

correct the fi neness as described above.

6.  Place the rotary knob on the adjusting spindle so that the arrow 

of the knob is positioned precisely on the symbol „fi ne“. Clockwise 

rotation must no longer be possible.
