STARSEEKER Professional Italian Accessories Bottomless 58mm Handle Set for Super58

Kit User Manual

To ensure your user experience and equipment safety, please strictly follow the instructions when using your Super58 Portable Handset Kit.

1. After installing the portable handle kit, tighten the pressure regulating knob (OPV) and then loosen it one turn for testing.

2. Do not exceed 15 Bar for extraction. Excessive pressure may cause the sealing ring to fold outwards, leading to leakage.

3. If the extraction pressure reaches 15 bar and there is no deceleration and the coffee output is very slow, immediately press the power button to interrupt the extraction. Wait for the pressure to release before testing again.

4. When the pressure is ≥15 Bar, you can fine-tune the pressure screw counterclockwise to adjust the coffee grind size. Grind slightly coarser before testing.

5. Please use the portable handle and carrier that come with your machine. Other non-standard portable handles may have poor sealing and leakage due to size differences.

*Friendly Reminder: When installing the kit, please tighten the screws to ensure the portafilter is fully inserted into the kit's groove. During initial use, leakage may occur. This should resolve after 2-3 uses at pressures not exceeding 15 Bar. If pressure is exceeded by more than 15 Bar and pressure is not stopped promptly, a "pop" sound and leakage may occur, which is normal. Please use with confidence. If leakage occurs due to the rubber ring shifting, clean the coffee grounds from the brew head, remove the rubber ring, clean it, and reinstall it to restore functionality.

*Not recommended for beginners. Using the portafilter kit requires some experience using semi-automatic coffee machines.
