4.3.3 Lock out the main switch and the air supply/exhaust switch
When the maintenance work is performed with the power supply and the air supply off, make sure to lock
the main switch and the air supply/exhaust switch with a padlock as shown below before the work. This is
to prevent a bystander from accidentally turning on the power and the air supply during the maintenance
work. Also, make sure to lock the main switch and the air supply/exhaust switch with a padlock when the
machine is left unused for a long period of time. Manage the key of the padlock according to the customer's
rules.

4.4 Cautions during machine operation
• Always make pre-operation checks before powering on the machine.
• Do not use an air blow tool when cleaning the machine. (Airborne dust will badly affect machine
operation.)
• Stop all machine operation before cleaning around the machine.
• Do not turn off the air during operation.
• Always make periodic inspections to prevent unexpected machine breakdowns.
• Allow only properly trained, experienced workers to perform repair and adjustment.
4.5 Cautions during power outage
If a power outage (blackout) occurs during automatic machine operation, always power off the machine to
prevent faulty operation and equipment damage after power has been restored. Remove items such as
boards that remain inside the machine.
4.6 Cautions regarding ferromagnetic fields
Some machines contain parts generating strong magnetic fields which may cause death, bodily injury, or
device malfunction. Always comply with the following instructions.
• Persons wearing electronic medical devices such as cardiac pacemakers and/or hearing aids must not
put any of their body parts into the machine.
• Persons wearing ID cards, purses, and/or wristwatches must keep away from the linear motor.
• Do not attempt to disassemble the linear motor (including surrounding covers).
• Do not bring tools close to the linear motor.
• Do not bring tools close to the magnetic scale.
• Do not put magnetic materials or objects close to the linear motor.
• Do not touch a portion close to the linear motor during operation or immediately after the operation
has been finished since such part is hot.

CAUTION
When disposing of a part generating strong magnetic fields such as a linear motor, dispose of it in compliance with the
laws and regulations of the country where the machine is used. Contact YAMAHA sales representatives for disposal of the
parts.
