INTRODUCTION

This equipment will store up-to six pounds of whole bean coffee in the hopper and grind it to a preset
grind and amount into an awaiting funnel and filter from most commercial drip coffee brewers. The
equipment is only for indoor use on a sturdy counter or shelf. Adequate space must be available
above the grinder to raise the lids when adding beans. Use only with whole bean coffee.

The grind is preset at the factory to drip specifications as set forth by the United States Department
of Commerce and adopted by the Coffee Brewing Center of the Pan American Coffee Bureau.
Adjustments may be made to alter both the amount and grind from the factory setting.

USER NOTICES

Carefully read and follow all notices on the grinder and in this manual. They were written for your
protection. All notices on the grinder are to be kept in good condition. Replace any unreadable or
damaged labels.
