Safety instructions

3. Safety

To ensure that the machine you purchased is used safely and correctly, always comply with the instructions

and rules in this manual regarding safety. However this manual cannot cover all items regarding safety in

detail. So it is extremely important that the operator or person handling the machine make correct decisions

regarding safety.

3.1 To ensure safety

To maintain the safety of the operator or person working with this machine, it is essential that it (including

external parts feeders) be installed correctly in compliance with the safety standards and conditions of that

country.

Complying with the safety regulations and laws of that country is the responsibility of the customer who

purchased this machine. The supervisor of this machine must take responsibility to ensure all measures have

been taken for machine safety.

3.1.1 Defining safety

1. Safety has priority over all other operations.

2. Safety is more important than any other task.

3. Safety is the foundation for work efficiency.

4. Safety begins with maintaining (keeping it neat and orderly) the work environment.

3.1.2 Causes of injuries and accidents

Most accidents are not something that occurs but something that are caused. So it is important to make an

effort NOT to cause accidents.

Hazardous actions

• Ignoring causes of accidents

• Working or operating equipment in cramped locations

• Working in locations or positions where safety cannot be ensured

• Unsafe machine operation and using equipment whose safety cannot be ensured

• Working or operating equipment at speeds where safety cannot be ensured

• Working or operating machines with safety equipment removed

• Performing work or tasks on top of a machine currently in operation

• Playing around or goofing off during work

• Performing maintenance or inspections without wearing safety gear

3.2 Using safety gear

Always wear safety gear when operating or servicing equipment.

Helmet : Use during maintenance work

Safety glasses or goggles : Use around light harmful to eyes and when applying lubricant and when handling organic

solvents.

Respiratory gear : Use when handling organic solvents

Safety gloves : Use when applying lubricant and when handling organic solvents.

3.3 Restrictions on machine use

3.3.1 Defining the operator and service personnel

CAUTION

Only the operator and service personnel having sufﬁcient knowledge of this machine should handle this machine.

Operator:

The operator is someone who has been trained by us in machine operation, has a thorough knowledge of the machine

operation manual and demonstrates adequate knowledge of machine operation and safety.

Main tasks of the operator include pre-operation checks, operation (component mounting) and making setups

(changeovers). The machine is only used in normal operating mode.

Service personnel:

The service personnel are those trained by us in machine maintenance as well as safety instruction and demonstrate a

thorough knowledge of safe handling of the machine according to the type and location of machine operation. They must

also understand hazardous sections of the machine and residual risks.

Main tasks of the service personnel include machine maintenance, repair, adjustment and management of the system.

The service personnel may make changes to the machine settings and operation in factory adjustment mode.

3.3.2 Restricting machine operation with passwords

Machine operating levels usable by the operator and service personnel (mentioned above) must be restricted

by password. This prevents the operator and service personnel from using the machine at a higher level than

allowed.

3.3.3 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.

Safety instructions

3.4 Cautions during machine operation

• Always make pre-operation checks before turning on the main power switch.

• 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.

3.5 Cautions during power outages

If a power outage (blackout) occurs during automatic machine operation, always turn the main power switch

off to prevent faulty operation and equipment damage after power has been restored. Remove items such as

boards that remain inside the machine.

3.6 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.

3.7 Handling the internal tape cutter

• Never supply electrical power and air to the machine while the covers for the tape cutter are removed.

• Tape cutter maintenance tasks must be performed by YAMAHA service personnel.

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.
