Your new coffee grinder is easy to operate and maintain. Before you place it in service, please have all personnel familiarize themselves with these instructions; then keep this manual in a convenient place for ready reference.

Set-up Procedures

1.You, the user, must determine the quantity of coffee you want to dispense as various types of coffee and brewing equipment require different quantities to obtain a quality cup of fresh ground, fresh brewed coffee.

Note: Because of the inherent properties of some decaffeinated coffee, it may be necessary to dispense a slightly greater amount to achieve the desired level of flavor extraction as in regular coffee. This should be evaluated based on the coffee you use as well as the brewing equipment used.

2.Adjust the timer inside the grinder if necessary, to dispense the desired weight of ground coffee (see Timer Adjustment Section on page 3). All grinders are factory set to deliver approximately 2 ounces of ground coffee. This weight is approximate, as the density of all coffee beans is not the same. The only way to ensure the desired portion is being dispensed is to weigh the coffee after it has been ground.

3.The grind texture can be adjusted, if necessary, to a finer or coarser grind (see “Grind Adjustment” section on page 5). The grind is factory set to deliver a standard autodrip grind.

How to Operate

1.Fill the hopper with the appropriate amount of whole bean coffee.

250RH Models: Place full hoppers on machine making sure the base of each hopper is seated in designated area. (Refer to Figure A)

2.Place the brew basket with coffee filter on rails (or basket arms).

3.Choose the type of coffee you wish to grind by pressing the rocker selection switch.

4.Push the start button on the front of the grinder.

5.When grinder stops, remove the brew basket.
