O-ring
When the O-ring inside the nozzle deteriorates and develops cracks, air leakage will occur. This will
reduce the maximum air pressure (negative pressure), and will cause problems with suction operation.
When the reduction in the maximum air pressure is found and the cause seems to be in the nozzle, replace
the O-ring inside the nozzle.
ACTION:
① Pull out the O-ring from the nozzle and clean inside the nozzle with an air blower.
② Insert a new O-ring into rear end of the nozzle.
③ Push the O-ring against the bottom inside the nozzle.
④ After the new O-ring has been set in place, attach the nozzle to the head and check for nozzle
clogging.
)
Checking the nozzle for clogging
NOTE: Do not apply silicon grease or the like to the O-ring since it may cause nozzle clogging.
■ Nozzle Filter
The nozzle filter keeps dust and dirt from entering inside of the nozzle. It also prevents the escape action
malfunction caused by the dust. Periodic cleaning of the nozzle filter must be performed.
ACTION:
① Clean the nozzle by blowing the air with an air blower from its rear end.
NOTE: Normally, cleaning with the air blow may be sufficient, but remove the O-ring and the filter and clean them
when the dirt is firmly attached to them.
NOTE: Nozzles with filter:
P005, P006, P013, P018, P019, P020 and Custom-made nozzles.
Dust and dirt are easily entered into a nozzle hole of large-diameter nozzles. (1.0mm or larger)

② Insert the flattened pin-edge of the jig between the O-ring and the nozzle filter, and pull out the O-ring
from the nozzle (Carefully pull out the jig and do not drop the O-ring.).

ACTION:
① Insert the filter with tweezers and adjust the position of the filter using the O-ring insertion jig.
Correct Incorrect
② Set the O-ring at the tip of the nozzle and slowly push it all the way to the bottom by using the O-ring
insertion jig.
③ Slowly pull out the insertion jig.
④ Check to make sure that the filter and the O-ring are set in place correctly.
