■ Inspection of Suction Pad (Nozzle No. P017, P018, P019, P020)

Check that the rubber suction pad located at the nozzle tip is free from scratches and cracks. If they are

found on the pad, replace the pad with a new one.

ACTION: Remove the old pad, apply silicon grease to the inner surface of a new pad, and then install it in the nozzle.

■ Applying Silicon Grease

After the nozzle is cleaned, it must be coated with silicon grease.

● Nozzle outer surface

Apply a slight amount of grease to the outer surface (indicated by dotted lines in the above illustration), and

then wipe it off with a dry cloth.

NOTE: Silicon grease must be applied so that it forms a thin film on the surface.

● Suction pad

Application of oil content is needed to prevent deterioration of the rubber. 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 so that 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.

● Inspection interval

Approx. once a month

Nozzle Holder

● Checking the nozzle holder escape

After grease is applied to the nozzle’s outer surface, attach the nozzle to the head and check the condition of

the nozzle holder escape.

NOTE: When the nozzle is placed in the head (nozzle holder), it can slide a few millimeters vertically. This nozzle

sliding movement is called nozzle holder escape.

ACTION:

① Attach the nozzle to the head.

② Push the nozzle gently with fingers up to the top dead center of the nozzle holder escape.

③ Release fingers gently and check that the nozzle returns to the lower dead center smoothly.

NOTE: If the nozzle holder escape is not smooth, there may be problems with component suction and placement. If

the nozzle gets caught or does not move smoothly, check the nozzle holder and nozzle’s inner/outer

surfaces for collection of foreign matter or scratches.

● Inspection interval

Approx. once a week
