8.5.6.1 Replace the Silencer
●
Check the silencer at regular intervals for contamination, following the instructions given in the Mainte-
nance section of the User Manual. To do this, unscrew the silencer and replace if necessary.
8.5.6.2 Clean or Replace the Vacuum Nozzle
To disassemble the vacuum nozzle
●
Loosen the two 2.5 mm hexagon socket head screws that fix the spacer in place (item A, Fig. 8.5.3).
●
Lift out the spacer and pull the vacuum nozzle out of its hole.
●
Check the vacuum nozzle (item 4, Fig. 8.5.3) for dirt and clean if necessary.
●
Check the tip of the vacuum nozzle for damage and replace if necessary.
●
Check the O-rings in the spacer (item 2) and on the vacuum nozzle (items 3 and 5) for damage. Replace
the O-rings if necessary. Lightly grease the new or cleaned O-rings with UNISILKON L 250L.
To reassemble the vacuum nozzle
Reverse the above sequence to reassemble.
8.5.6.3 Replace Collet Bush PK-3
●
Detach the hose coupling from the connector with the collet bush (item 1 or 7, Fig. 8.5.3).

Ensure that the hole for the collet bush is clean.
●
Insert the new collet bush and push it into the hole.
8.5.6.4 Vacuum Test With the SITEST Program
If the vacuum generator is functioning correctly and the vacuum test with the station software or the SITEST
program still returns incorrect values, the fault may be either on the IC head board or the I/O boards.
●
Use the relevant circuit diagram to trace the fault.
