Maintenance of options
1. Ionizer
As the ionizer is used for a long time, the discharge needle (electrode) is worn out and deteriorates.
Additionally, the periodic cleaning work is needed to maintain the static elimination effect and ion balance.
c
CAUTION
A voltage is applied to the discharge needle tip of the ionizer. Be careful not to touch the tip directly by hand when
performing the maintenance work inside the machine.

NOTE
The performance and capability of the ionizer to remove static electricity depends on the operating environment or
the materials and shape of the items that the static electricity is removed. YAMAHA does not guarantee such
performance or capability.

Maintenance of options
1.1 Cleaning ionizer discharge needle (Monthly)
Perform this work monthly or if the LED (+ PREC or - PREC) on the ionizer main unit is lit in green.
1
Power off the ionizer.
e
1. The power supply to ionizer is stopped by
pressing emergency stop button and
then open the machine safety cover.
2.
Check that all LEDs on ionizer is turned
off.

WARNING
A VOLTAGE REMAINS ON THE DISCHARGE NEEDLE
IMMEDIATELY AFTER TURNING OFF THE POWER. BE AWARE
THAT TOUCHING THE DISCHARGE NEEDLE IMMEDIATELY
AFTER TURNING OFF THE POWER IS HAZARDOUS.
2
Turn off the air supply.
Turn the air supply/exhaust switch (valve) on
the lower left of the machine clockwise (EXT)
to turn off the main air.

Clean the discharge needle.
1. Wipe off dirt on discharge needle and
sensor (gold sheet) with accessory brush
or cotton swab.
2. If the dirt cannot be removed, apply IPA
to a cotton swab slightly and clean the
discharge needle.
3. If IPA is used, leave discharge needle for
a while after cleaning to dry it out.
n
NOTE
It is also possible to clean the discharge needle by
detaching the discharge needle unit. See "1.2
Replacing ionizer discharge needle (2 year)" on next
page for attaching and detaching the discharge
needle unit.
c
CAUTION
Do not dip the discharge needle unit to the IPA when
cleaning the detached discharge needle unit. If
applying a high voltage while IPA remains in the unit,
the ionizer main unit may be damaged.
4
Supply the air and power on the
ionizer.
1. Turn the air supply/exhaust switch (valve)
and supply the air to the machine.
2. Close the machine safety cover and
press the [READY] button.
3.
Check that the green LED of "GOOD" on
ionizer is turned on. Make sure that no
error is occurring.

1.2 Replacing ionizer discharge needle (2-year)
Replace the ionizer discharge needle (KHN-M83P1-00X: Needle Set/ 4 sets of discharge needles) once every 2
years or if the LED (+/-PREC, +/-ERR) showing the ion balance error does not go off even after performing the
work steps in "1.1 Cleaning ionizer discharge needle (Monthly)". One ionizer contains 8 discharge needles.
Normally, one each of ionizer is installed on front and rear of the machine. Therefore, 4 discharge needle
packs are required for maintenance work of one machine.

Remove the discharge needle.
As shown in the figure on the right, grasp
and squeeze the holder's opposing claws at
2 points and squeeze them toward each
other, then extract discharge needle.

Replace the discharge needle.
When installing the new discharge needle,
the notched area on the mounting side must
be aligned with the discharge needle unit's
protruding part. When correctly aligned,
press it in.
