warranty.

Part No.

■ Air Passage

Clean the air passage (from the air filter assy. to the nozzle) periodically to maintain machine accuracy.

Give an air blow from an air tube.

■ Air Filter

Take out air filter elements from air filter assy., once a week, to check if they are dirty. Replace the elements

if they are clogged with dust.

Nozzle

■ Cleaning.

If the dispensing fluid is left in a nozzle for a long time, it will harden. Once the fluid hardens in the nozzle,

the fluid in a syringe cannot be dispensed. So clean nozzles before the fluid gets hard. When you change the

dispensing fluid and when you are not using a nozzle for a long time, clean the nozzle in the same manner.

● Timing of Cleaning

・When the amount of dispensing is coming to smaller.

(When discharging or dot size are coming smaller.)

・When dispensing amount is not stable.

・When using the nozzle after a long interval.

NOTE: Cleaning timing depends on the state of storage. Follow the instruction of the manufacturer for

storing the material.

● Preparations

・ Syringe

・ Saucer

NOTE: Syringe does not need a needle. About 10cc is enough for the syringe capacity.
