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
The tip of the ionizer discharge needle is sharp and the voltage is applied. The power supply to the ionizer is stopped
by opening the safety cover. However, make sure not to touch the tip of the ionizer discharge needle when
performing maintenance in the machine.

• Normal operation (GOOD): Lit in blue.
• Large ion balance correction amount (+PREC, -PREC): Lit in green.
The contamination of the discharge needle advances. The discharge needle needs to be cleaned.
• Ion balance error (+ERR, -ERR) : Flashes in red.
The discharge needle may be contaminated or deteriorate significantly. The relevant error is also given on the machine side.

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
absolute ethanol to a cotton swab
slightly and clean the discharge needle.
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 absolute
ethanol when cleaning the detached discharge needle
unit. If applying a high voltage while absolute ethanol
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 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.
