Installation Instructions Be sure to check the product images above for a step-by-step visual guide. Prepare Your Grinder: Remove the original hopper and clean out all old beans and grounds. We recommend using a vacuum cleaner to ensure the grinder inlet is completely free of debris. Note: Do not use water, as it can rust the grinder burrs. Insert the Lock Ring: Remove the lock ring from the hopper, align the tabs with the slots in your grinder inlet, and drop it in. Press down firmly to fully seat the lock ring so that the flexible arms are aligned with the holes in the side of the grinder inlet. Attach the Hopper: Align the hopper tabs with the locking ring slots and place the hopper into the lock ring. Press down and twist clockwise 90 degrees until the "ARO Espresso" logo is at the 3 o'clock or 9 o'clock position and the grinder safety trigger engages. This may require some force as the O-ring creates a seal on the grinder inlet. You can use the aluminum arms inside of the hopper that hold the anti-popcorn baffle for better grip. To remove the hopper, simply twist it counterclockwise until it releases from the orange lock ring. Then remove the orange ring and seal. You may need to pull back the arms on the lock ring to release them. Setting your grind size to the finest setting will also assist with removing the hopper as it lowers the outer burr and relieves any pressure on the lock ring. Please send us a message if you need any assistance with installation or removal! Usage Instructions Be sure to check the product images above for a step-by-step visual guide.
