Some grinder have a tamp attached to the machine or you may use a separate manual tamp. Whichever type you use, make sure it is clean and fits snugly into the portafilter. A snug fit is important to make sure you apply even pressure on the ground coffee when pressing it into the portafilter.
The dumpbox is used to collect the used coffee grounds after you have extracted an espresso. It is also called a knock box or waste tube. The used grounds form a cake (a compressed disc of ground coffee) in the filter basket. You need to knock the portafilter against the bar that runs across the top of the dumpbox to dislodge the cake.
Before service, make sure the dumpbox is empty and clean. Some workplaces use a plastic liner to make cleaning and emptying easier. If you use liners, make sure you have enough available.
Make sure:
you have enough milk jugs available in appropriate sizes
milk jugs are clean
milk thermometers are available and working correctly.
You also need to make sure you have enough clean cloths for cleaning the milk wand.
