CLEANING

The use of a damp cloth rinsed in any mild, non-abrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Matic equipment. Care should be taken not to scratch the hopper with any abrasive material. Regular cleaning will keep your grinder looking new for years.

PREVENTIVE MAINTENANCE

Bunn-O-Matic®Corporation recommends that preventive maintenance be performed at regular intervals. Maintenance should be performed by a qualified service technician. For Technical Service, contact Bunn-O-Matic®Corporation at 1-800-286-6070.

NOTE: Replacement parts or service caused by failure to perform required maintenance is not covered by warranty.

6-Month

Weekly Cleaning plus replace the dechaffer assembly.

1-Year

1.On grinders with slide plates check the slide plates and clean.

2.Inspect and clean/replace burrs and grind chamber if necessary.

3.Adjust the burrs and grind time to your specifications for particulate size and throw weight.

COFFEE GRINDING

1.Visually inspect the selected hopper for an ample supply of whole bean coffee.

2.Carafe Brewing: Place a paper filter into brew funnel. Insert funnel into rails and push until it stops.

3.French Press: Place French Press on grinder base and push towards rear until it stops.

4.Choose the batch size and side of grinder to use.

5.Press GRIND. The grinding action will stop automatically after the preset amount of ground coffee is dispensed into the funnel.

ADJUSTMENTS

The grind can be set from very fine to very coarse. The amount may be adjusted for use in most commercial coffee brewers. The following procedures should be used to make adjustments. A change in the burr adjustment will also change the amount dispensed. Any adjustment of the burrs should be followed by an adjustment of the timer.

Burr Adjustment

1.Unplug the grinder and empty all beans from the hoppers.

2.Plug in the grinder, press and release GRIND (with either hopper selected). Run a few grind cycles until all of the coffee in the grind chamber is used.

3.Remove funnel with filter and carefully tip the grinder over on its back.

4. Press GRIND and slowly turn the adjusting screw in a clockwise direction until a metallic whine is heard due to the rubbing of the grinding burrs. (It may be necessary to start more than one grind cycle to obtain this sound.)

5. Make a mark with a pen on the decal to note the position of the arrow on the grind adjustment screw.

6. The following settings approximately correspond to the CBC recognized grinds. All are referenced from the arrow position noted in #5.

direction.

 

DRIP GRIND: Rotate the adjusting screw 8 hash marks in a counterclockwise direction.

 

REGULAR (COARSE) GRIND: Rotate the adjusting screw 10 hash marks in a counterclockwise direction.

NOTE: Exact adjustment will vary according to bean roast or added flavoring.
