(3) Checking of Attached Vacuum Nozzle

• After the vacuum nozzle is attached, rotate the rotary turret with the

cam hand-rotating wheel to let the nozzle pass over the dropped nozzle

detection plate. Check that the end of the nozzle does not touch the

plate. If it touches the plate, re-attach the vacuum nozzle.

The vacuum nozzle should be set in the descending mode

when it passes over the dropped nozzle detection plate.

(4) Nozzle Offset Teaching

Refer to "5.4 "Head/Nozzle" Tab" in "Section 6" of "Volume 2: Opera-

tion (Supervisor)" for details and perform teaching operations.

Wipe off dirt and dust on the end of a nozzle which was detected as

defective through teaching operation and then re-perform the teaching

operation.

Refer to "5.4 "Head/Nozzle" Tab" in "Section 6" of "Volume 2:

Operation (Supervisor)" for the items to be checked when a

nozzle is detected as a defective one through teaching opera-

tion.

When the machine operation is started with a defective

nozzle (detected by teaching operation) attached, the nozzle

is bypassed and not used.

1.4.5 Disassembly, Cleaning, and Lubrication of Miniature Stroke

Bearing

Since the disassembly, cleaning, and lubrication work

of the miniature stroke bearings requires highly so-

phisticated technique, consult our service personnel

for details.

••

• Time for Inspection, Cleaning, and Lubrication

Perform inspections every month.

Cleaning and lubrication are required when dirt and dust have accu-

mulated on the sliding part of the shaft and the movement is ham-

pered or on the hollow portion of the shaft and the suction force has

deteriorated.

Be sure to clean the miniature stroke bearing every 6 months.

••

• Disassembly of Miniature Stroke Bearing

Disassembly Procedure

(1) Set all nozzles to "L Level".

Refer to "4.2.2 "Mnl Opn Menu" Tab" in "Sec-

tion 6 (Volume 2: Operation (Supervisor))" for

the detailed information on how to change the

nozzle level.

(2) Make the X/Y table escape.

Refer to "4.2.1 "Noz Cleaning" Tab" in "Sec-

tion 6 (Volume 2: Operation (Supervisor))" for

the detailed information on how to make the

X/Y table escape.

(3) Turn off the power and air sources of the ma-

chine to discharge the air from the machine.

(4) Detachment of Head Assembly

(4-1) Loosen 2 M4L12 bolts (upper ones) and 2

M4L16 bolts (lower ones) fastening the head

and detach the head assembly.

(4-2) Pull out the air hose.

(4-3) Pull the head forward to detach.
