Checking the Reflecting Rings (for Vacuum Pump Operation)
Checking the holding circuit (for compressed air operation)
Fit the holding circuit and silencer again by following the above instructions in reverse order. This
task must be carried out by authorized personnel. For removal and installation details, read the ser-
vice manual for your machine. Also observe the following instructions:
Dismantle the reflecting ring. Loosen the screw fas-
tening the cover and remove the cover, together with
the reflecting ring.
Check the sealing disk and the O-ring on the reflect-
ing ring for contamination and damage and replace
this if necessary.
Tighten the three fastening screws with a torque of
25+5 Ncm.
Hand-tighten the screw fastening the cover.
Dismantle the vacuum distributor holding circuit.
Only loosen the three protruding fastening screws on
the holding circuit and remove the holding circuit.
Check the seat of the holding circuit (1) for dirt.
Clean the seat with a lint-free cloth, if required.
Check the holding circuit (2) and the seal (3) for dirt
and damage. If heavily soiled or damaged, replace
the holding circuit with a new one.
Clean the holding circuit with compressed air. Make
sure that no dirt gets into the Venturi nozzles (4).
CAUTION
Installation instructions
During fitting, make sure that the centering pin is inserted into the opposite hole in the seat
of the holding circuit, otherwise the holding circuit could be fitted at an incorrect angle (twist-
ed by 120 degrees).
Make sure that the seal is inserted correctly!
Tighten the three fastening screws of the holding circuit with 25+5 Ncm.
Insert the silencer once more and screw it in place. The screw may only be tightened "hand-
