Secure the FNC nozzle assembly.
1. Turn the index holder so that the bevel
gear faces the opposite side.
2. Align the surface of the bevel gear shaft
horizontally and slide the stopper block
back to the original position. Then tighten
the bolt with the M1.5 hex wrench to
secure the stopper block.
3. Rotate the spline shaft so the bevel gear
faces the front. With the spline shaft
lowered, use the dedicated hex wrench
(0.7) to tighten the set screw that
prevents one of the lock pin cams from
being retracted in the shaft.

CAUTION
• When tightening the stopper block screws, hold the
edge of the FNC assembly so it won't rotate.
• The screwdriver bit size may slightly differ between
manufacturers. Use the screwdriver that matches
the recessed pattern on the screw head.

Check the movement after
reassembly.
1. After reassembling the FNC nozzle
assembly, press the [Head] button on the
[Unit]-[Head] tab screen to lower the
reassembled head.
2. Lower the FNC lock pin cam.
Lowering this cam releases the FNC lock
pin, allowing you to rotate the bevel
gear by hand.
3. With the cam still lowered, check that
rotating the larger bevel gear also
rotates the smaller bevel gear smoothly.

2. Monthly or bimonthly inspection
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. 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.
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 [Head] button on the
[Unit]-[Head] tab screen.
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 of about
10mm diameter 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.
Insert an air blow gun into the air joint
section and blow air while holding a
cleaning cloth or paper towel against the
lower end of the head.
6
Lubricate the slide section and
check the movement.
Apply turbine oil to the buffing section (slide
section) and push up the nozzle holder by
hand several times to check that it moves
up and down smoothly.
