!
ATTENTION: Do not get any oil on the encoder disk.
NOTE
You must not slide or rotate the z axis (sleeve) by hand as the clamping device has frictional contact with the
z axis. The oil will distribute itself during placement as a result of the movement of the sleeve.
Do not get any oil on the encoder disk. A dirty encoder disk will result in counting errors or cause errors in
positioning the d axis in the reference position.
●
Remove the cover. Take a clean, lint-free cloth and watchmaker’s oil and apply a thin film of oil to the cir-
cumference of the sleeve.
●
Use proprietary lens cleaning cloths straight from the package (in other words, damp) and after oiling the
sleeve clean thoroughly the entire surface of the encoder disk until the cloth remains clean.
●
To reach all points of the encoder disk, proceed as follows:
Close the safety hoods
→
Switch the machine on and press the start button
→
Call the
Gantry 1 func-
tions
menu. Select
IC head functions
and click on
Turn D axis
. Each time you click on this option the axis
will make a quarter turn (90
°)
.
9.6.3 Maintenance of the Pick-Up Star O-Ring
NOTE
Always select the
Return (nozzle)
function when you want to remove the nozzle from, or insert the nozzle in
the placement head pick-up star. In the first place you will thus avoid damaging the sleeve or nozzle, and in
the second place you will thus ensure that the last current nozzle is registered by the computer as having
been returned. This is necessary if placement is to continue smoothly.

O-ring 6.5 x 1.6 Viton 80, Item no. 00308445-01
●
If you have complied with the sequence of work described above, the current nozzle will already have been
returned to the nozzle changer. The o-ring is thereby rendered accessible for maintenance work (see Fig.
9.6.3).
●
Remove the o-ring from the annular groove of the pick-up star. Clean both the groove and the o-ring with
alcohol and dry them. If you detect damage, fit a new o-ring.
●
Grease the cleaned or new o-ring sparingly with Unisilkon L250L and put it back in the annular groove
without overstretching the o-ring.
●
Clean the friction wheel of the d-drive unit (Section 9.6.4 from Page 9 - 77).

9.6.4 Cleaning the Friction ring of the D Drive Unit
●
Move the IC head to the service position.
●
Remove the protective panel (2 M3 hexagon socket screws).
●
Clean the visible area at the circumference of the friction ring (see Fig. 9.6.4) with alcohol and a clean
cloth.

3 Use alcohol to clean the circumference of the friction ring.
●
Switch the machine on and rotate the d axis as described below:
Hold the cloth dampened with alcohol against the circumference of the friction ring:
Select the
IC head
menu in the
Gantry 1 functions
menu and click on the
Turn D axis
button.
(Each time you click on this option the axis will make a quarter-turn. )
Clean in this way the entire circumference of the friction wheel.
