Lubricate and replace piston rings
The V-rings on the piston are susceptible to wear and need lubrication and/or replacement every once
in a while. If the lever starts to show increased stop-motion behaviour during a shot you should plan to
lubricate the V-rings. Upon inspection of the V-rings you may conclude that it is better to replace the
V-rings.

procedure
1. Turn the machine OFF and let the steam boiler cool down to well below 100°C (212°F).
2. Close water supply to the machine, pull the brew-levers down to release remaining pressure in the
coffee section. Gently move the brew-levers into (upper) resting position.
3. Remove the Allen bolt (A) from the back of the lever mechanism and loosen the spanner to
dismount the Bowden cable.
4. Remove the 4 Allen bolts (B) that hold the top onto the main section of the group. The spacer
tubes (c) may fall out.
5. Pull the top vertically from the group.
To replace the V-rings;
•
Remove the Allen bolt M8x20 to take the piston apart, see Figure 24.
•
Note the correct orientation of each V-ring when replacing.
•
Mount the piston back together.
