Periodic maintenance items
1. Weekly inspection
This section mainly describes weekly inspection and cleaning.
1.1 Inspecting and cleaning the nozzles
A spring-action or defective nozzle leaf spring may cause pickup errors. To prevent this, inspect each nozzle.
1.1.1 Inspecting and cleaning the slide section
n
Checking the spring action
Check the spring-action of the nozzles. Press on a nozzle. If it returns normally, there is no problem. However,
if the return action is poor (sluggish), pickup errors and recognition errors will occur.
c
CAUTION
When checking by pressing the nozzle tip, do not apply excessive force. The condition is normal if the tip returns to its
original position after being pressed in approx. 1 mm.
Checking the nozzle spring action
Press on the nozzle tip with your hand.

Cleaning the slide section
e
1
Remove nozzles.
1. Press the emergency stop button and
then open the machine safety cover.
2. Remove nozzles from the head. If the
machine is equipped with the nozzle
station, press the [Nozzle Stn Shutter]
button to open the nozzle station shutter
and remove nozzles.
2
Clean the slide section.
Apply IPA (isoprophyl alcohol) or ethanol to
the slide section. Push the nozzle tip several
times to repeat the buffing action (spring
action) to clean the slide section. After
cleaning, blow sufficient air to remove IPA or
ethanol.
3
Lubricate the slide section.
Using a precision screwdriver or similar tool
with a pointed tip, apply a small amount of
turbine oil (just enough so that it sinks in) to
the slide section.

4
Check the spring-action.
Push the nozzle tip several times to repeat
the buffing action and spread turbine oil.
Use a lint-free cleaning cloth to wipe away
excess oil from around the nozzle.
53302-L1-00
5
Remove excess oil remaining in the
nozzle.
Using an air blow tool (option), blow air for
about 5 seconds from the nozzle tip, and for
about 5 seconds from the nozzle attachment
side. Repeat this process a few times to
remove excess turbine oil remaining in the
nozzle.
n
NOTE
A thin coat of oil is enough to lubricate the slide section.
6
Check that the oil was removed.
Place commercially-available oil blotting
paper and check residual oil in the nozzle.
n
NOTE
Performing step 5 is usually sufficient to remove oil
remaining in the nozzle. However, if oil still remains, blow
air through the nozzle once again.

7
Reinstall the nozzle.
After checking one more time no oil
remaining in the nozzle, return the nozzle to
the head.
n
NOTE
If removed nozzles from the nozzle station, return them
to the nozzle storage positions.

Step 6
Checking for residual oil
Oil blotting paper
Oil will appear after blowing air (first
time) for about 5 seconds from the
nozzle tip.
Repeat the air blow for about 5
seconds each from the nozzle tip
and from the attachment side.
This task is finished when oil no
longer appears.

1.1.2 Checking the nozzle leaf springs
If nozzle leaf springs cannot hold a nozzle securely, this adversely affects pickup, recognition and mounting
operations. Periodically check the leaf springs for nozzle holding status.
n
Nozzle leaf spring inspection points
Check the following points by removing the nozzle and reattaching it to the nozzle holder.
• The nozzle leaf spring has enough gripping force.
• There is no gap between the leaf springs and the nozzle.
• The nozzle leaf spring is not deformed.
• The nozzle detaching/attaching part of the leaf spring is not worn out.
• Mounting screw should be tightened.
Checking the leaf spring condition
Screw should
be tightened.
Leaf spring should not be
warped or deformed.
There should be
no gap.
Leaf spring should
not be frayed.

NOTE
IIf any problem is found during the check work shown above, replace the leaf springs referring to chapter 4, "2.
Replacing nozzle leaf springs".
As a rule, be sure to replace a pair of parts even when only the leaf spring on one side deteriorates
n
NOTE
Return the nozzles to the head where the nozzles were removed.
If removed nozzles from the nozzle station, return them to the nozzle storage positions.
