Cleaning/lubricating the upper part of the nozzle shaft
The procedure for cleaning and lubricating the upper part of RS head nozzle shafts is described below.
The dedicated oil (KMB-M3855-00X) is required to lubricate the upper part of nozzle shafts.
1
Prepare for work.
e
1. Remove all items sensitive to magnetic fields
such as wristwatches and magnetic ID cards.
2. Press the emergency stop button and detach
the feeder exchange carriage.
3. Open the machine safety cover and move
the head unit to a convenient position for
maintenance work.
2
Cleaning the upper part of the shaft.
1. Use your finger to press down the nozzle
shaft spring of the head to be cleaned.
2. Wipe away dust or dirt from the upper part
of the nozzle shaft using a cotton swab.
3
Apply the specified oil (oil for upper
part of shaft) using a cotton swab
dampened in the oil, on the upper part
of the shaft as a thin uniform coat in
approximately 10 mm range.

Note
Id the target head spring locates where being difcult to
lower, see "Lowering RM head/nozzle shafts" above and
turn the N-axis gear to rotate the rotary.

Clean and lubricate the other shafts by
the procedure of Step 2 and 3.

6.2.3 Cleaning/lubricating the vacuum selector (spool)
The RM 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 2 years as a general guide.
Lubricating the spool requires the dedicated grease (grease for spool: GREASE 30G KMB-M3854-00X).
1
Prepare for work.
e
1. Remove all items sensitive to magnetic fields
such as wristwatches and magnetic ID cards.
2. Press the emergency stop button and detach
the feeder exchange carriage. Then open
the machine safety cover.
3. Move the head unit to a convenient position
for maintenance work and place a square
cloth beneath it.
2
Pull out the spool by gripping its upper
side with fingers and pulling out
upward.
Use a longnose pliers or the similar if the spool
is difficult to pinch with fingers.
n
NOTE
Id the spool locates where being difficult to lower, see
"Lowering RM head/nozzle shafts" above and turn the
N-axis gear to rotate the rotary.
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 by wiping off old grease
and dirt on the spool using a lint-free
cloth.
4
Apply a thin uniform coat of the
specified grease (dedicated grease for
spool) by hand to the spool.
5
Return the spool to its original position
and insert it all the way seated.
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).
6
Clean and lubricate the other spools.
1. Clean/lubricate rest of spools with the same
procedures as Step 2 to 5.
2. Retrieve a square cloth after working.

Switching vacuum/blow with spool
The RM head switches vacuum/blow by moving up/down the spool, using up/down operation of V-axes
located at left and right side of head unit.
• When the spool descends, air is supplied to nozzle shaft.
• When the spool ascends, nozzle shaft is vacuated.
