Grinds
Before shipment, this grinder has been tested with
coffee and has been accurately adjusted to deliver
ground coffee to normal auto drip specifications.
The Grinding Burrs are made of an extremely hard and
wear resistant material. From time to time, grind
adjustments (see following instructions) may be
necessary. 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. 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.

Protection
This grinder is equipped with both a circuit breaker and
a shear disc to protect motor and burrs.
Circuit Breaker
This grinder is equipped with a circuit breaker to
protect the motor from overloading. When the circuit
breaker trips, the reset button will pop out
approximately 1/4” which stops 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, wait two minutes then push in the 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. In this case, the Grinder Head should
be cleaned as described in
Shear Disc Replacement .
