A few habits to keep you, your Z1, and your burrs safe.
Before you turn it on
- Plug your Z1 into the voltage shown on its back plate, and always use a grounded outlet. Do not use a travel plug adapter. See Using Your Z1 in Another Country (Voltage).
- Make sure the bean funnel and one piece chute are securely in place.
- Set the dial above 200µm before you turn the grinder on. Never start the Z1 with the burrs touching. Doing so blows the internal safety fuse.
- Never turn the dial more than 1400µm (slightly more than two full rotations coarser). The dial can unscrew from the front assembly.
While it is running
- Keep fingers, hands, and objects away from the exit chute, the burr chamber, and the auger while the grinder is plugged in.
- Grind only coffee beans from reputable suppliers.
- Do not pour liquid into the funnel.
- If the grinder stalls, turn it OFF right away and unplug it. Then follow Troubleshooting: Z1 Stalls, Struggles, or Stops With a Loud Noise.
Cleaning and maintenance
- Turn the grinder OFF and unplug it before any maintenance. Never open the grinder while it is plugged in.
- Never immerse the grinder base in water or any other liquid.
- Do not use metal tools on the burrs. They can scratch them.
- Leave the grease in the adjustment mechanism. It is designed to run lubricated.
- Do not overtighten burr pins. Tighten each pin until snug, then back it off 1/8 to 1/4 turn.
- Get comfortable using your Z1 before you open it, and only take it apart as far as our guides describe: Opening, Cleaning, and Closing Your Z1 and Changing Burrs on Your Z1.
When to stop using your grinder
Stop grinding if your burrs are chipped or damaged. Damaged burrs can cause inconsistent grind quality and further damage to the grinder. See Changing Burrs on Your Z1.
