Can I use this for espresso grinding?

How do I clean the burrs?
Disassemble the grinder according to the manual and use a soft, dry brush to remove coffee particles. Do not wash with water.
What is the purpose of the sieve mesh?
The sieve mesh is used to sift out fine particles, allowing for a more uniform grind and a cleaner cup of coffee.
Is the handle removable?
Yes, the handle is designed to be easily attached and removed for storage and ease of use.
How many bearings are in the shaft system?

Troubleshooting
The adjustment dial feels stuck or difficult to turn.
Clear any trapped coffee beans or dust from the burr chamber by tapping the body lightly or using a brush to clean the burr teeth.
Grind consistency seems uneven.
Check that the center shaft is properly seated and that the burrs are free of debris. Ensure the 3-bearing mechanism is not loose.
The handle is difficult to turn.
You may be grinding too finely for the chosen bean density; increase the grind size setting slightly or reduce the amount of beans fed into the hopper at one time.

Setup, Compatibility & Care
To begin, ensure the adjustment dial is set to the zero-point before adding beans. To adjust, rotate the dial until you feel resistance and then dial back to your preferred setting. The Rapidity-3 is compatible with a wide range of brewing methods, including French press, V60, Chemex, and manual espresso machines. For maintenance, disassemble the grinder using the magnetic releases periodically to remove residual coffee oils. Use a soft brush to sweep out the burrs; avoid using water or detergents as these can lead to rust or damage to the internal bearing components. Regularly check that the adjustment ring moves freely and is not obstructed by trapped grounds.
