STEP 1
Turn the filling knob to the left side (against clockwise) to move the piston down. Please make sure, that you have no ink in the barrel anymore!
Now you can see the thread and the two notches in the piston unit.
STEP 2
Insert the removal correctly in the notches.
STEP 3
Turn the filling knob to the right side (clockwise) to fix the tool properly. The removal sits now close to the knob without any jerking.
STEP 4
Turn the removal to the left side (against clockwise) to unscrew the piston unit.
Do not unlock the removal before you have unscrewed the piston unit completely to avoid scratches or dents on the thread.
STEP 5
Open the filling knob by turning to the left side (against clockwise) to release the removal as well as the piston.
To screw in the piston unit back into the barrell (after cleaning, flushing and lubricating) rerun Step 4 to Step 1!
