Before starting work
1. 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.
1.1 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 entrusted with this machine’s operation must take responsibility to ensure
all measures have been taken to ensure machine safety.
■ Who is the operator? Who are the service personnel?
c
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 and 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 inspections, 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 who also
demonstrate a thorough knowledge of safe handling of the machine according to the type and location of machine
operation. They must also have an understanding of hazardous sections of the machine and residual risks.
Main tasks of service personnel include machine maintenance, repair, adjustment and management of the system. Changes
to the machine settings and operation in factory adjustment mode (service mode) are allowed.
■ 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.
