Daily maintenance items
Before beginning work
In most cases, maintenance should be performed with the main power turned off.
However, some maintenance tasks are performed under emergency stop conditions with the power turned on.
In such cases, ensure adequate safety and press the emergency stop before beginning the maintenance.
The power is turned on during maintenance where any servo-axis must be operated or machine operation
checked. In this case, also ensure adequate safety before beginning the maintenance.
When operating the machine, make sure the following conditions are met.
n
Operating conditions
1. Supply air pressure is kept at correct pressure.
2. All safety covers are closed.
3. Nozzles and other units are attached in place.
n
NOTE
The description "Cancel the emergency stop." is in the procedures of this manual. It means "releasing the emergency
stop and pressing the [Ready] button to turn the servo on".

Daily maintenance items
1. Checking the nozzle
Solder sticking to the nozzle tip or a clogged nozzle hole can cause component pickup errors and
recognition errors. Poor nozzle spring action can also cause pickup and mounting errors. To prevent such
problems, inspect each nozzle daily.

How to check for a dirty nozzle (with the [Tip Dirt Check] button)
The term "dirty nozzle" 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. [Tip Dirt 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
[Tip Dirt Check] is a function that recognizes the reflection of the light around the nozzle center. So, applicable nozzles
are those with a small tip, such as 301A, 302A, and 311A.
n
NOTE
Since the nozzle specification may vary depending on
the machine, some machines may require additional
settings. See the operator's manual, chapter 3 "1.9
Confirming nozzles" for detailed settings.

How to check for clogged nozzles (on the [Unit] - [Head] tab screen)
The term "clogged nozzle" used here indicates that material such as solder is adhering to the nozzle hole, causing a rise
in negative pressure even if no component is being picked up by the nozzle. This state might cause problems such as
component mounting errors. Check for clogged nozzles with the following procedure using the Type 302A as an example.
n
NOTE
When checking other nozzles and their vacuum levels, see the next section "1.1.1 Vacuum level when nozzle is
open"in this chapter.

Reset the numerical value.
Open the [Unit] - [Head] tab screen. Then
press the [Reset] button on the lower right of
the screen to reset the vacuum level values.
3
Generate negative pressure.
On the [Unit] - [Head] tab screen, set the
[Vacuum] buttons for all heads to ON. When
this value starts rising, wait 5 to 10 seconds
and set to OFF.
4
Check the vacuum levels.
Change the all "Max" values shown in red on
the [Head] tab screen. When using Type 302
nozzle and this value is 60 to 110, it is in the
normal range. If higher than 110, the nozzle
hole might be dirty. Clean the nozzle while
referring to "1.2 Nozzle cleaning"in Chapter
3.

NOTE
If a correct value cannot be obtained by performing steps 1 to 4 after cleaning the nozzle, the inside of the spline
shaft might be not clean. See chapter 3, "5.1.1 Cleaning the spline shaft"to clean it.
