Silencer
: Turn the silencer counterclockwise to remove.
a Clean the holes leading to the venturi nozzles using a cottonwool bud lightly moistened with
ethyl alcohol.
: Check the silencer for dirt.
If the silencer is discolored, replace it with a new one, and reverse the order described above
to fit.
12
Be careful not to damage the O-ring.
: Check the plastic mount for the silencer to ensure that it is not broken (10,000 head).
Assembling the vacuum generator
: Assemble the block and venturi nozzles and carefully tighten the screws.
s Reattach the compressed air hoses.
Use the pliers provided in the service box for the DLM 1 and DLM 1-6 heads.
Make sure that the right hose is attached to the right connection.
12
The hoses must latch firmly into the couplings.

: Refit the head cover (if necessary).
: Use the “Single Functions” menu to pick up the nozzles once more.
Trial placement run
Separating the front and back parts of the head can change the distance between the component
camera and the PCB camera.
: Carry out a trial component placement run to test whether the placement accuracy is still the
same.
: If the placement accuracy cannot be guaranteed, remeasure the placement head.
