This section explains how to clean and lubricate a nozzle holder after inspection.
2.1 Cleaning and lubricating a nozzle holder
If the nozzle holder spring-action is poor, this adversely affects all operations of component pickup, recognition
and mounting operations. Periodically (once every two months) clean the nozzle holder with alcohol (IPA or
ethanol) and lubricate it with turbine oil to maintain smooth movement.
1
Press the emergency stop button.
e
The machine must be in emergency stop to ensure
safety during work.
2
Remove the nozzles and lower the heads.
Remove the nozzles attached to the nozzle holders
to be cleaned, and then lower the heads by
pressing the joint section.
3
Clean the nozzle holder by immersing it
in alcohol.
1. Place a cloth or absorbent paper under the
head.
2. Prepare a small container (for example, plastic
35mm film container) deep enough to hold the
entire nozzle holder. Then pour this container
about 80% full of alcohol.
3. Bring this alcohol container up against the
nozzle shaft so the entire nozzle holder is
immersed in alcohol for several seconds.
4. Remove the alcohol container and push up on
the nozzle holder with your finger several times.

4
Immerse the nozzle holder in alcohol
again.
Repeat steps 3 and 4 until the spring-action
becomes smooth.
5
Use air blow to remove foreign matter.
While placing a cleaning cloth or paper just under
the lower end of the head, insert the air blow gun
into the air joint section and blow air.
6
Lubricate the spring-action parts and
check the movement.
Apply turbine oil to the spring-action parts and
push up the nozzle holder by hand several times to
check that it moves up and down smoothly.

Wipe away the old grease on the ball
screw as follows.
1. Move the head (or conveyor table) to the one
end of its axis and wipe away the old grease on
the ball screw with cleaning paper or cloth that
does not leave dust or residue.
