3.2.3 Cleaning and lubricating the vacuum selector (spool)
The RS head switches between vacuum and blow by way of an up and down spool movement in each head.
The spool should be cleaned and lubricated about every 3 months as a general guide.
Lubricating the spool requires the dedicated grease (grease for spool: GREASE 30G KMB-M3854-00X).

1. Remove all items sensitive to magnetic fields such as wristwatches and magnetic ID cards.
2. Press the emergency stop button and then open the machine safety cover.
3. Use the CLAMP ON/OFF switch to lower the feeder exchange carriage and detach it.
4. Move the head unit to a convenient position for maintenance work.
2
Pull out the spool.
Grip the upper side of the spool with fingers
and pull out the spool upward.

NOTE
If the spool is in a position where difficult to remove, turn
the rotary unit referring to "How to lower RS head/nozzle
shafts" described earlier. The rotary unit can also be
turned by turning the R-axis gear manually.
c
CAUTION
Remove the spool completely. Turning the rotary unit
while removing the spool may cause contact with the
V-axis (Valve axis / spool up-down axis).
3
Clean the spool.
Wipe off old grease and dirt on the spool
with a lint-free cloth.
4
Apply grease.
Apply a thin uniform coat of the specified
grease (dedicated grease for spool) by
hand to the spool.

Return the spool to its original
position.
Insert the spool all the way to its original
position.
c
CAUTION
Firmly insert the spool all the way to its original position.
Turning the rotary unit while inserting the spool may
cause contact with the V-axis (Valve axis / spool
up-down axis).

Clean and lubricate the other
spools.
1. Clean/lubricate rest of spools with the
same procedures as Step 2 to 5.
2. Remove square cloth after working.
