Pull the filter mats out (under the servo and control units) between the unit and base plate of the machine
base.
●
Lift or bend open the grille cover of the filter mats.
●
Clean the filter mats thoroughly on both sides with the vacuum cleaner.
●
If you detect damage insert a new filter mat between the grilles.
●
Close the grille cover and slide it back in place beneath the unit.
●
Close the control and servo cabinet doors and switch the machine on at the main switch.

9.3.2 PCB Handling
9.3.2.1 Cleaning the Conveyor Belts
NOTE
Components jammed in the conveyor area can easily cause the conveyor to jam or to boards being clamped
unevenly, which in turn can lead to an interruption of the placement sequence.

Cleaning and oiling the recirculating ball screws of the width adjustment device
●
Clean thoroughly the recirculating ball screws of the width adjustment device by pulling a cloth soaked
in alcohol through each of the threads in turn.
●
If necessary use a brush soaked in alcohol. The bearings should not come into contact with alcohol.
●
After drying, apply a light and even film of watchmaker’s oil to the circumference of the spherical rotat-
ing liners.
●
Cleaning and greasing the flat guideways of the width adjustment
●
Rub the slide faces of the flat guideways with a lint-free cloth soaked in alcohol.
●
Grease these slide faces evenly and sparingly with Staburags N12. Remove excess grease.
