Periodic maintenance items
1. Weekly maintenance
This section mainly describes weekly maintenance items.
1.1 Nozzle inspection
A faulty buffing operation (spring action) can cause pickup errors. To prevent this, inspect each nozzle.
1.1.1 Inspecting nozzle slide section
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 1 mm.
Checking the nozzle spring action
Example: Type 302A nozzle
Press on the nozzle tip with finger.

Periodic maintenance items
1.1.2 Checking leaf spring/roller lock
Inspect the nozzle holding status of the head periodically.
• An unstable holding force at the nozzle leaf spring (hereafter "leaf spring") can adversely affect pickup, recognition,
and mounting operations.
• If the roller lock is loose, this may adversely affect the nozzle holding force.
• If the roller is scratched, this may cause recognition errors.
n
Leaf spring inspection points
Check the following points by attaching/detaching the nozzle to/from 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 assembly).
• The leaf spring is not warped or deformed.
• The gripping part of the leaf spring is not frayed.
• Mounting bolt and mounting screw are not loose.
• No rollers are scratched.
Checking the leaf spring condition
They are not loose.

NOTE
If any problem is found during the check work shown above, replace the leaf springs or roller lock while referring to
"2.1 Replacing nozzle leaf springs" or "2.2 FM head: Replacing roller lock" in Chapter 6.
As a rule, be sure to replace a pair of components even when only the leaf spring or roller on one side deteriorates
.
n
NOTE
Return the removed nozzles to the original positions of the head.
If removed nozzles from the nozzle station (option), return them to the original storage positions.
