■ Air Passage

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

accuracy and placement rate. Give an air blow either from nozzle holder or from an air tube.

■ Air Filter

Nozzle

When obstacles such as solder paste is stuffed up in the nozzle, the suction becomes weak. And existence

of an obstacle at the nozzle tip prevents the vision processing from recognizing smaller components. Clean

nozzles to avoid these troubles.

■ Nozzle Cleaning with Air Blow

Clean nozzles with alcohol and then blow away dust with a blower (more than once a week). When

choking error occurs, also do the cleaning of the nozzle.

Be careful not to apply alcohol to identification marks. Quickly wipe off if

applied.

■ Nozzle Cleaning using Wire (1)

If the stain on the nozzle is stubborn, clean the nozzle using a wire.

Take care not to get injured with the fine wire when cleaning the nozzle.
