6.4 Replacing Consumables and Cleaning
See "Caution" (10) on p.07.
(1) The interior of the pump is extremely hot immediately after operation. After stopping
the pump, leave it for 30 minutes or more and begin replacing consumables and
cleaning only after checking that it has cooled sufficiently.
(2) To prevent ingestion of microscopic particles in the air, use a dust mask and gloves
when replacing components and cleaning.
(3) To prevent injury, wear gloves when replacing consumables.
