Check the belt rotating condition.
1. Make sure that the board clamp top
surface is approx. 0.5mm lower than the
belt upper surface.
2. Close the machine safety cover and
cancel the emergency stop. If the
machine could be equipped with a
carriage, set the carriage.
3. On the [Unit] - [Conveyor] screen, press
the [Conveyor In] button or [Conveyor
Out] button to turn on the conveyor
motor and check the belt rotation.
4. If the rotation speed fluctuates or there is
slack in the belt, adjust the position of
the tensioner (pulley/pulley bracket) that
tension is applied, and then check the
rotation again.

CAUTION
When the difference between the belt upper surface
and board clamp top surface is very little, the board
transfer error may occur easily. In this case, contact
YAMAHA sales representative.

4. Three-month inspection
4.1 Cleaning and replacing the ejector filter
Although depending on the air supply conditions and operating time, ejectors should be inspected once every
3 months. Use an air blow tool to remove dust buildups when small. We recommend replacing the air filter if
heavy dust deposits are found.

1
Make the preparations for the
cleaning and replacing work.
1. Press the emergency stop button and
then open the machine safety cover.
2. If the machine is equipped with a
carriage, remove the carriage to allow
you to easily access the head.
3. Move the head unit forward.
4. Place a square cloth under the head unit.

Clean the filter.
Use tweezers to take the filter out of the
ejector. When there is only a little dust in the
filter, use an air blow tool to blow it away
and return the filter back to the original
position.

NOTE
If there are heavy dust deposits in the filter or the filter
has discolored, replace it with a new filter (K46-M8527-
C0X). As a general guide, filters should be replaced
once every 3 months, although this depends on the
actual operating time.

Reattach the filter cap.
1. Fit the filter into the filter cap and insert it
into the ejector.
2. Turn the filter cap to the right until it locks
and clicks.

CAUTION
When attaching the filter, be careful to make sure the
O-ring does not come out from between the manifold
and the filter cap.
