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.
c
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.
4.7 Handling the internal tape cutter
The internal tape cutter could cause severe injury upon misusing. Adhere strictly the following precautions.
• Never supply electrical power and air to the machine while the covers of tape cutter are removed.
• Never put your hands or fingers into the tape emitting duct of the tape cutter.
• Never touch the tape cutter blade.
• Tape cutter maintenance tasks must be performed by YAMAHA service personnel.
n
NOTE
YAMAHA recommends to inspect a tape cutter (and to lubricate with disassembly if needed) once a year, although this
may vary depending on the machine condition or machine operating environment. YAMAHA also recommends to replace
tape cutter blade once every 3 years. Contact YAMAHA sales representatives for more details.

4.8 Keeping hands away from moving parts
During use of this machine, the customer’s equipment and operating conditions might allow the operator’s
hands to come into contact with moving parts. Use the following safety measure options to avoid possible
danger where openings or gaps are found on the machine.
►
Dummy feeder
Use dummy feeders as safety measures to fill a gap between tape feeders. Install dummy feeders on the
feeder plate the same way as normal feeders in order to prevent hands from entering.

CAUTION
To install or remove a dummy feeder, be sure to first press emergency stop button and then open cover. The
machine has structure that does not allow installing or removing dummy feeder when machine is in operation.
However, inserting dummy feeder inside cover during operation may cause serious accidents, so be careful
not to attempt it.

NOTE
One-stop covers cannot be installed or removed during operation. The machine must be in a stopped state because
the section where a feeder exchange carriage is to be installed will move up and down for the installation or removal
of the feeder exchange carriage.

Muzzle plate
Use these plates as a safety measure for the board conveyor entrance and exit openings. Each plate is
movable, so adjust the mounting position to match the boards to be produced.

CAUTION
When installing a unit such as a loader or an unloader on the upstream or the downstream side of the machine, set the
muzzle plates to the opening of the board conveyor entrance or the board conveyor exit to make the opening small.
