Key specifications
 Motor power: 150 W
 Bean capacity: 50 g
 Product type: Blade grinder
 Colour: Black
 Operating voltage/frequency: 220–240 V, 50 Hz
How to use
Place the desired amount of whole beans (up to 50 g) into the grinding chamber, close the lid securely and press the control to start grinding. For a more even texture, pulse the grinder in short bursts rather than running continuously. Stop the motor when the ground coffee reaches the preferred consistency, then unplug the unit, open the lid and transfer the grounds to your brewer. Allow the grinder to cool between extended uses to avoid motor overheating.
Usage recommendations
For consistent results, grind small amounts according to brewing method and pulse in short intervals to achieve medium to medium–fine particle size. Clean the grinding chamber and lid after each use to prevent flavor transfer between different coffee varieties. Avoid overfilling beyond the 50 g capacity and do not operate the grinder continuously for long periods to preserve motor life.
