Normally all adjustments are made before the machine leaves the factory. Check that these adjustments
are correct and change them if necessary; proceed as follows to access them:

Remove the screws next to the cup warmer and pull the side panel towards the back to remove it.
Adjusting the temperature
The temperatures of each group and the steam boiler are adjusted independently from the control screen
via the "adjustments" menu. (See the chapter entitled: MACHINE ADJUSTMENT)
Adjusting the high pressure valve

the group heating cycle.

Use a pin spanner. After adjustment remember to tighten the lock-nut.
