Periodic maintenance items
1. Weekly inspection
This section mainly describes weekly inspection and cleaning.
1.1 Checking and cleaning the nozzles
If buffing action (spring action) is poor, component pickup errors may occur. To prevent such problems,
periodically check and clean each nozzle.
1.1.1 Buffing area inspection
Check the spring action of the nozzles. Press on a nozzle and if it returns normally there is no problem.
However, if the return action is poor (sluggish) then pickup errors and recognition errors will occur.
c
CAUTION
When checking by pressing the nozzle tip, use care to avoid applying excessive force. The condition is normal if the
tip returns to its original position after being pressed in approximately 1mm.
Checking the nozzle spring action
Example showing type 302A nozzle
Press on the nozzle tip with your hand.
Returns to original
position
Returns sluggishly
or does not return.

1.1.2 Checking the leaf spring
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
Leaf spring inspection points
Check the following points by removing the nozzle and reattaching it to the nozzle holder.
• The leaf spring has enough gripping force.
• There is no gap between the leaf springs and the nozzle (FM head : nozzle arm assy).
• The leaf spring is not warped or deformed.
• The gripping part of the leaf spring is not frayed.
• No screws are loose.
Checking the leaf spring condition
Screw should be tightened.
There should be
no gap.
There should be no
deformation or wear.

NOTE
If any problem is found during the check work shown above, replace the leaf springs while referring to "2. Nozzle leaf
springs" in Chapter 6.
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 nozzle you have removed to the head.
When the nozzle has been removed from the nozzle station, return it correctly to the storage position where the nozzle
has been removed.
