preventative maintenance
Preventative maintenance should be performed on a
quarterly basis and should be carried out by a service
technician. This maintenance should include checking
and adjusting the coffee dose, deep cleaning the grind
chambers, and replacing the burrs if applicable. Burr
replacement should occur every 2000 lbs or if burrs
are damaged.
