Nozzle
When obstacles such as solder paste are stuck to or clogged in the nozzle, the suction becomes weak.
Existence of such obstacles on the nozzle tip also prevents the vision processing from correctly recognizing
smaller components. Clean the nozzle in order to avoid these troubles.
■ Nozzle Cleaning with Air Blow
Clean the tip of the nozzles with alcohol and then blow away obstacles and dust with an air blower (more
than once a week). When choking error occurs, also clean the nozzle in the same way.
Be careful not to apply alcohol to identification marks. Quickly wipe off if
applied.
■ Nozzle Cleaning Using Wire (1)
Normally, cleaning the nozzles with the air blow may be sufficient, but use a wire to clean the nozzles when
obstacles and dirt are firmly stuck on them.
NOTE: Before cleaning the nozzle by using a wire, the O-ring and the nozzle filter inside the nozzle must be
removed. Cleaning the nozzle with a wire without removing them may result in the damage or loss of them.
After the nozzle is cleaned, make sure to re-install them using a special tool.
NOTE: For a description of how to remove/install the O-ring and nozzle filter, refer to “Removing O-ring and
Nozzle filter” and “Attaching O-ring and Nozzle filter” given later in this manual.
Take care not to get injured with the fine wire when cleaning the nozzle.
ACTION:
① Have a wire ready.
(300mm length, 0.1mm diam. Part No. KV8-M8887-00X)
② Remove the O-ring and nozzle filter from the nozzle.
③ Pass the wire through the nozzle hole.
④ Wind to fasten the wire between both ends of the nozzle cleaner assy.

⑤ Move the nozzle back and forth to clean the nozzle hole.
⑥ Remove the wire and blow some air into the nozzle hole.
■ Nozzle Cleaning Using Wire (2)
Fix both ends of the wire with an adhesive tape as shown below and move the nozzle back and forth to clean
the nozzle hole. In this case, the adhesive may remain on both ends of the wire. Be sure to clean the wire
ends before pulling out the wire from the nozzle.
■ Check of Suction Pad (Nozzle No. P017, P018, P019, P020)
Check to make sure that a rubber suction pad on the nozzle tip is free from scratches and cracks. When
scratches and cracks are found on the pad, replace it with a new one.
ACTION: Remove the old pad, apply silicon grease to the inner surface of a new pad, and then install it to the nozzle.

● Nozzle Outer Surface
Apply a slight amount of grease to the outer surface (see illustration above), and then wipe it off with a dry
cloth.
NOTE: Silicon grease must be applied lightly enough as if it forms a thin film on the surface.
● Suction Pad
Lubricate the suction pad in order to prevent it from deterioration. Apply a slight amount of grease to the
outer surface of the suction pad, and then wipe it off with a dry cloth.
NOTE: Silicon grease must be applied lightly enough as if it forms a thin film on the surface.
Do not apply excessive amounts of grease. This may cause collection of dirt
or dust in the air passage and on placed components, resulting in component
placement failure.
