1. Maintaining machine performance
The most important condition essential for maintaining the performance of the machine you purchased is
using it under good environmental conditions. Performing daily maintenance and periodic inspections is also
absolutely essential.

Maintenance
1.2 Importance of periodic inspections and cleaning
Periodic inspections and cleaning are extremely important maintenance tasks. Failure to perform inspections
and cleaning will prevent the machine from delivering full performance and may lead to component mounting
problems or equipment breakdowns.
Examples:
• Dirty nozzles might cause mistakes in component recognition and cause mounting errors.
• Dirty air paths may cause numerous pickup and mounting errors.
• Inadequate feeder and feeder plate inspections may cause pickup errors.
• Dirty optical system (camera, lighting, etc.) may cause recognition errors.
• Poor greasing of axes may cause abnormal noises.
• Poor inspections such as of valves may cause errors in PCB clamping and conveying.
As these examples show, failure to make inspections may lead to equipment problems. It is strongly
recommended to perform periodic inspections and cleaning to ensure the machine is used under optimal
conditions.

NOTE
The "inspection check sheet", a list of inspection items is included at the end of this manual for effective inspection.
Use the check sheet when inspecting.

Maintenance
2. Preparing for maintenance tasks
Tasks described in this section focus mainly on replacing parts (consumable parts) that might cause a gradual
loss of machine functions during use. This section also describes how the user can easily replace parts
(replaceable parts) when a breakdown occurs.
2.1 Consumable parts
The term "consumable parts" in this manual indicates parts subject to continual wear during use causing
gradual loss of functions. The following parts are classified in this manual as consumable parts and should be
replaced as needed during maintenance.
