Z axis (front part of the head)
a Use a brush or cottonwool buds to remove dirt from the toothed belt for the Z-axis.
: Clean the rollers, cogs and the toothed belt using a cottonwool bud or lint-free cloth moistened
with ethyl alcohol.
: Check the toothed belt for wear.
If the toothed belt shows signs of wear, replace it with a new belt (see
Service Manual).
: Grease the toothed belt sparingly with ISOFLEX TOPAS NCA 52, then remove any excess
grease.
s Check that the Z axis guide runs easily and without backlash.
: Check the jaws for wear.
If you find any defects in the Z axis or jaws, return the placement head to Munich for repair.
Oiling the miniature roller table
: Move the Z axis into its bottom position.
: Wipe off the needle of the syringe.
Don't press oil out of the syringe. A visible drop would be too much oil.

d Place the needle on the grooves of the miniature roller table. By placing it enough oil gets into
the grooves (by capillary attraction).
: Move the Z axis up and down several times to distribute the film of oil.
Distributor disk
f Remove the distributor disk.
: Blow it through with compressed air.
g Clean it using a lint-free cloth moistened with ethyl alcohol.
: Grease it very sparingly on the back with ISOFLEX TOPAS NCA 52 to ensure that it remains
sealed with respect to the star.
Remove any visible excess grease.
12
There must NOT be any grease in the holes.
: Place the distributor disk on a clean surface.
