Chapter 3 Periodic maintenance items
1. Weekly maintenance
Here describes the maintenance items required to perform once a week.
1.1 Nozzle inspection
The troubles of buffing movement (spring movement) or nozzle leaf spring lead the pickup error. Perform the
inspection of each nozzle to prevent the troubles.
1.1.1 Slide section inspection
Check the nozzle buffing condition. It does not matter when a nozzle returns to its normal position upon
pushing, but when it does not, pickup error or recognition error may occur.
c
Caution
- Touching the nozzle tip directly by finger may cause adherence of oil or so. Use such as a flat plate instead.
- Upon pushing a nozzle tip to check its condition, do not push too much. It is enough when a nozzle returns after it is
pushed approximately 1mm.

1.1.2 Check the condition of nozzle leaf spring
Inspect the nozzle holding condition of head periodically. When the holding ability of nozzle leaf spring
(hereinafter referred to as leaf spring) is not stable, it creates adverse effect to all the picking up, recognition,
and mounting.
►
Inspetion items for leaf spring
Attach/detach the nozzle from nozzle station and check the following items.
• Has enough nozzle holding ability
• No clearance between the leaf spring and nozzle
• No deformation, or wearing at the contact point with nozzle
• No looseness at mounting screw of leaf spring
Inspection items for leaf spring
No looseness at mounting screw
No gap
No deformation or wearing

NOTE
When some items above have problem, see Chapter 5 "2.1 HM head: Replacing nozzle leaf springs"and replace the
leaf spring. Even when one side of leaf spring deteriorates, essentially the both of one pair should be replaced.

NOTE
When the nozzles are removed from head or nozzle station, they should be returned to their original position.
