LG9-M71A1-00X SOLENOID VALVE

■ 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.

● Cleaning

① Remove the remaining dispensing fluid with a cotton swab.

Insert the syringe with full of air into nozzle adapter opening. Hold the nozzle and slowly push the air

into the adapter to push out the residue.

NOTE: Syringe must be inserted tight to avoid air leak, or the residual may not be pushed out.

② Insert the syringe containing some solvent into nozzle adapter opening.

③ Press the syringe hard and push the solvent out.

④ Repeat the procedure until the nozzle becomes clean enough.

NOTE: Nozzle is not held by hand in the picture above, but it must be held to avoid slipping off.

NOTE: Use the solvent specified by the manufacturer of dispensing fluid. Some solvents may deteriorate a

syringe and a sealant inside of it. If this happens, replace the syringe.

⑤ Blow off the remained solvent with air blow. Check with your eye if the nozzle hole is through.
