Periodic maintenance items

Set all spools to "Vacuum position".

Move all spools on relevant head unit to

upper end (vacuum position).

533G4-N9-00

TIP

The spool upper end locates where it can be moved

up without resistance. The spool can be moved up to

the middle of gear on shaft (upper gear). The stroke of

top/bottom of spool is approx. 3 mm. The spool is

detached by moving it up more than 3 mm. Make sure

not to move it up excessively.

Blow the inside of shaft.

1. Pressing down V-axis of relevant rod side manually lowers the relevant spool and blows the inside of

nozzle shaft.

2. Move up/down Z-axis knob on relevant rod side several times to move up/down shaft under the

knob.

3. R (mount angle) of all heads can be turned not by turning rotary but by turning R-axis gear holding

the label where head numbers are indicated with hand. Turn them 120 degrees.

4. Move up/down Z-axis knob of relevant rod several times to move up/down shaft under Z-axis.

5. Perform the works from 3 to 4 again.

6. Move up V-axis manually to move the relevant spool to the upper end (vacuum position).

7. Turn the rotary to perform the works from 1 to 6 for all heads.

Check vacuum level.

Check vacuum level without nozzles/filters.

See "How to check for clogged nozzles (on

• Reference value of vacuum level: 90 or less

If the vacuum level is out of the value,

perform Step 5 to 9 again for relevant nozzle

shaft.

Attach the filters.

1. See "2.6.1 Inspecting and replacing the

air filters" to attach new filters to all heads.

2. Remove square cloth after working.

Return spools to original position.

1. Close the machine cover and set

carriage.

2. Cancel the emergency stop.

3. Open [Unit] - [Head] screen.

4. Select the table to perform the work.

5. Pressing [Recover Valve Pos] returns

spools to the reset positions.
