8. Maintenance
8.1 Precautionary Items before Maintenance
This session describes how to perform inspections, cleaning, lubrication, and
adjustment to keep the flux dispensing units in good shape.
It is recommended that periodic maintenance of the flux dispensing units
should be ensured.
CAUTION
Only a well-trained service person should perform maintenance
tasks carefully through the specified procedures.
8.2 Preparation for Maintenance
Required Items for Cleaning and Lubrication
• Rag
Use a rag made of such material as cotton, etc., that produces as less
waste thread as possible.
Notice
Remaining waste thread may cause the flux dispensing unit to
break down.
• Alcohol
Do not use alcohol for any spots other than the specified ones.
