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

2.Place a paper filter into the brew funnel. The filter must not be folded-over or tilted to one side.

3.Insert the funnel into the funnel rails and push until it stops.

4.Momentarily place the switch in the “START” (right) position. The grinding action will stop automatically after the preset amount of ground coffee is dispensed into the funnel.

5.Remove the funnel from the grinder and level the bed of grounds by gently shaking.

6.The loaded funnel is now ready for use in any commercial drip coffee brewer according to the manufacturer’s instructions.

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 hopper.

2.Plug-in the grinder, momentarily place the Off/On/Start switch in the “START” (right) position, and run a few grind cycles until all of the cof- fee in the grind chamber is used-up.

3.Remove the upper front inspection panel.

4.Loosen the burr adjustment screw from its locked position.

5.Place the Off/On/Start switch in the “START” (right) position 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.)

6.Turn plastic grind indicator until screw slot lines up with “O” on the indica- tor.
