Temporary placing of upper cover and precautions
The upper cover can be placed temporarily upon handles of feeder exchange carriage.
Also, a cover identification label attached to upper cover carries machine serial number and number of
carriage set position.
The upper cover is not compatible for other carriage set position or other machine, as the guide position
is adjusted for the correspond machine upon assembling and then the carriage is shipped. Use with the
machine/carriage set position written on cover identification label.

1. Checking the nozzle

Chapter 2 Daily maintenance items
1. Checking the nozzle
Solder sticking to the nozzle tip or a clogged nozzle hole can cause component pickup error and
recognition error. Moreover, poor spring action of nozzles may cause pickup errors. Inspect each nozzle
on a daily basis to prevent the errors.
1.1 Checking with software
█
How to check for a dirty nozzle (with the [Nozzle Cln Check] button)
The term "Nozzle Clean" as used here indicates shiny material such as solder adhering to the nozzle tip.
This shiny portion might be mistaken for a component and cause recognition errors. [Nozzle Cln Check] is a
tool that judges the nozzle contamination status by recognizing the nozzle tip in the non-component status
with the camera.
n
NOTE
The [Nozzle Cln Check] is a function that recognizes the
reflection of the light around the nozzle center. Therefore,
applicable nozzles are those with a small tip, such as
Type 8104A and 8105A.
