Operating Procedures 

1.  Turn grinder on/off switch to the on position. 

•  The power switch will illuminate to indicate that the grinder has power and is operational. 

2.  Fill the hopper(s) with whole coffee beans. 

•  The GR-2 models have two 5lb. removable hoppers. These hoppers must sit squarely on the floor 

of the hopper chamber. When placing the hoppers inside the hopper chamber make sure chamber 

is clear of stray whole beans and debris. The hoppers will not sit properly if this is not done. 

•  Both hoppers must be placed into the grinder before operating grinder; and plastic covers must be 

on hoppers.  

3.  Place the brew basket with paper coffee filter in the plastic holding arms. 

•  The plastic arms will hold all FETCO brew baskets up to 52H models; and will fit most all other 

manufactures. 

•  All other sizes, FETCO recommends placing paper coffee filters on lower shelf and grinding 

directly into filter. 

4.  Press portion switch. (Factory Defaults) 

•  Small portion: 4 ounces 

•  Medium portion: (Available only on GR-1.3 and GR-2.3.) Approximately 6 ounces 

•  Large portion: 8 ounces 

5.  Allow grinder to complete its cycle then remove brew basket from plastic holding arms. 

Cleaning: 

a)  Use stainless steel cleaner on all stainless steel surfaces. (Never use abrasives on these surfaces.) 

b)  Use damp cloth on other surfaces. Use mild detergent as needed. 

c)  Removable hoppers on GR-2 models are dish washer safe (the covers are not). 

d)  After washing hoppers FETCO recommends hand drying them. 

Service 

Warranty

Support Department at (800) 338-2699. A Return Authorization number will be issued for all parts replaced under

Principles of Operation  

Timing Systems: 

The timing system consists of the programmable digital timer board, the start switch, the hopper solenoid (GR -2 

models only), the solid state capacitor, and the grinder motor.  

When the start switch is pressed, the timer starts its’ cycle. 

GR-1 

The timer energizes the capacitor, and the motor is then energized. 

When the timer finishes its cycle, it removes voltage from the capacitor, and the motor. The grind cycle timed 

sequence is complete.
