NOTE
The item numbers of the nozzles and diaphragms will be found in Section 9.6.7, Page 9 - 87.
Material and equipment: Nozzle removal tool, Item No. 00311448-01
You will already have returned the current nozzle to the nozzle changer by selecting
Single functions →
Gantry 1 → IC head
→ Return (nozzle)
.
●
Make a note of the nozzle types and corresponding garage numbers. You will need these allocations later
for refitting the nozzles. Specification of the garage numbers is shown in Fig. 9.6.11.
●
Remove all nozzles from the nozzle changer with the aid of the nozzle removal tool. Proceed as shown in
Fig. 9.6.8.

9.6.6.2 Checking and Maintaining the Nozzles
●
Carry out maintenance of the nozzles as shown in Fig. 9.6.9.
●
Check the nozzles and the diaphragms and replace any damaged diaphragm.
Please refer to Fig. 9.6.10 for the procedure for replacing diaphragms. The item numbers for the dia-
phragms are given in Tab. 9.6.1, Page 87. For maintenance of the diaphragms you will require talcum
powder (see Tab. 9.2.9, Page 14).
NOTE
Rubbing over with talcum prevents components sticking to the diaphragm after being set down on the
board. The diaphragm must not come into contact with spirit or alcohol.
●
Check the suction faces of the nozzles without diaphragm: if you detect damage use the corresponding
new nozzles. For the item numbers, see Fig. 9.6.11, Page 9 - 87.
