Do not regrind coffee powder 

Do not attempt to use the grinder grinding anything else other than roasted 
coffee beans. 

Maintenance and Service 

 

 

 

Following this rule will ensure long-lasting and reliable performance of your 
Grinder. 

Check the state of the grinding blades periodically (approximately every 
100kg of grinded coffee). Good condition blades will result in a high quality 
grind and prevent the Grinder’s over-heating. Replace grinding blades every 
1,000kg of grinded coffee (with normal hardness blades). 

The noise level of a grinder is a god indicator of its general condition. Be 
aware of the Grinder’s noise level. In case the noise level is higher than 
normal or irregular noises are coming from within the Grinder, get certified 
personnel to perform an overall check of the Grinder. 

BEOFRE ANY MAINTENANCE OR DISASSEMBLY PROCEDURE MAKE 
SURE THE GRIDNER IS EMPTY OF COFFEE BEANS AND CLEAN OF 
POWDER 

Removing the grind setting knob: 

Turn the grind knob to finest grinding position. (fig 8-1) 

Use a flat screwdriver (provided with the grinder) to remove the knob’s main 
center screw 

Pull out the knob (fig 8-2) 

After removing the grind setting knob, please note the silicone sliding 
positionless cushion relative positon of the marks on the grinding body and on 
the internal dial knob, if no further setting is required refrain from changing the 
position of the internal knob (fig 8-3) 

Warning: All technical handling operations, such as installation, 
maintenance, or service should be performed by certified personnel 
or by your local dealer.
