Coffee Grind Profile, Grind Adjustment, Current

Coffee Grind Profile

Before shipment, this grinder has been tested with coffee and has been accurately adjusted to deliver a standard autodrip grind.

The Grinding Burrs are made of an extremely hard and wear resistant alloy. From time to time, grind adjustments (see instructions below) may be necessary as the burrs wear. If the grind runs coarser than expected after normal adjustment and the grind time has increased, the burrs may have excess wear and should be replaced. The burrs are warranted for 3 years or 30,000 pounds of coffee. See your warranty for details. New burrs should always be installed as a pair, never one or the other, as they are accurately ground and lapped in pairs. Old burrs cannot be resharpened.

Note: Adjusting the grind may alter the portion of coffee dispensed. After grind adjustment, weigh portion and adjust, if necessary (see “How to Adjust the Portion”).

Current

It is absolutely essential that full voltage and amperage always be available as it takes full power to grind

coffee. NEVER connect to an overloaded line or a two or three way plug, otherwise serious damage to the motor may result.

Do not use an extension cord.

Protection

This grinder is equipped with both a circuit breaker and a shear disc to protect motor and burrs if a foreign object, such as a nail or rock, gets into the coffee.

Circuit Breaker

This grinder is equipped with a circuit breaker to protect the motor from overloading. When the circuit breaker operates, the reset button will pop out approximately 1/4” which cuts off the power to the grinder. The reset button is located above the power cord on the back of the grinder. To reset the circuit breaker, push the reset button in. You will hear a click as it resets. If the grinder does not operate after resetting the circuit breaker, there may be an obstruction in the grinding mechanism that is stalling the motor. In this case, the Grinder Head should be cleaned out as described in the Shear Disc Replacement section of this manual.

Lubrication

All bearings have been oiled for life. No further oiling is necessary.
