Operating Instructions

always be available for ready reference.

Grinds
Before shipment, your grinder is adjusted to accurately grind for each brewing method indicated. The Grinding
Burrs are made of an extremely hard and wear resistant alloy. From time to time grind adjustments (see Grind
Adjustment section in this manual) 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. Ask for a copy of our complete
Warranty for details. New burrs should always be installed as a pair, never one or the other, as they are accu-
rately ground and lapped in pairs.
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 then cuts off power to the grinder. The reset
button is located on the front panel of the Model 810, 835 and 875. To reset the circuit breaker, push in the
reset button. 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. Turn the grind selector knob
all the way to the left. Try restarting the grinder. If the circuit breaker “trips” again, the obstruction was not able
to pass. In this case, the Grinder Head should be cleaned out as described in the Shear Disc Replacement sec-
tion of this manual.
Current
It is 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 will occur. DO
NOT USE AN EXTENSION CORD.
