Safety devices-Thermal cut off
This grinder is equipped with and thermal cut off sensor. If your grinder becomes jammed with a
foreign object and the burrs are no longer spinning, the power to the motor will be disconnected
to avoid damage if overheating occurs. The burrs may become jammed if you adjust to the
coffee too fine. If this occurs please disconnect grinder from the power supply, loosen the burrs,
and wait till grinder cools off (approximately 15 minutes). NEVER try to release whatever is
jammed in the burrs while the machine is plugged in. It is possible for the grinder burrs to start
rotating if you try to remove whatever is blocking the burrs while the machine is on. This could
cause personal injury. Please contact technical assistance if problem persists.

Safety devices- Safety Screws
There are safety screws located on the adjustment collar for the hopper and grind adjustment.
These screws are not to be removed by the end user. The grind adjustment safety screw must
never be removed as this would expose you to high speed rotating parts. This screw also
makes sure that the burrs cannot be totally removed by unscrewing. There are two holes in the
ring nut that will inhibit the collar from being totally unscrewed. If by some chance you unscrew
the burrs totally be conscience that the threads are super fine and will pose resistance if there is
coffee between them. Also, threads WILL cross thread if not properly installed. This will cause
irreparable damage to your grinder. Please follow all safety recommendations.
Cleaning
Please follow the cleaning recommendations outlined in the manual. NEVER use water in any
fashion to clean the inside of the grinder. To clean the inside of the grinder without removing the
grinding ring, please use cleaning pills. Please refer to link below.
