READ CAREFULLY BEFORE USING THIS
MANUAL
Introduction
This machine is a dicing saw for cutting silicon wafers and glass circuit boards
(workpieces, hereafter).
It has the rotary sections which rotate at high speed, the high-voltage sections
which may cause electric shock hazards and the drive sections which may
catch the operator's body and clothing.
If the machine is not properly operated, safety hazards may cause serious
injury or death.
Read before using the machine
Before using the machine, thoroughly read this manual and follow the
instructions set forth in this manual.
To assure safety in the operation and maintenance of the machine, it is
important that you know the location of potential safety hazards. It is difficult
for DISCO to foresee each and every potential safety hazard. However, this
manual carries various precautionary notes and warnings to indicate the
presence of all foreseeable potential safety hazards. For increased safety
assurance, it is therefore essential that you observe all the precautions and
other relevant instructions set forth in this manual.
If you modify the machine without prior consent of DISCO or repair it in a
manner not stated in this manual, the safety assurance features of the machine
may be seriously affected.
Never attempt to modify or repair the machine in a manner not approved by
DISCO.

Hazard level
The safety precautions set forth in this document are classified into DANGER,
WARNING and CAUTION categories which represent three degree of hazards
latent in the machine. These categories are defined as detailed below in
accordance with the seriousness and probability level of the hazard. In addition
to the above three safety precaution levels, NOTICE is used to give safety
usage instructions to the user.
Before using the machine, be sure to read and understand all the associated
safety precautions set forth in the manual.
Hazard levels are classified as follows:
DANGER
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious
injury.
This symbol is used for the incident in which the
damage is serious and there is high probability of
occurrence.
WARNING
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury.
This symbol is used for the incident in which the
damage is serious but there is not high probability of
occurrence.
CAUTION
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury.
This symbol is used for the incident in which the
damage is slight and there is not high probability of
occurrence.
CAUTION
If you cannot avoid the incident in question, an accident
of physical damage may be caused.
NOTICE
Indicates the safe way of using the machine as well as
precautions to avoid accidents that may result in
property damage.

1. General Safety Precautions
General safety precautions
This section describes the general safety precautions that should be understood
before operation and observed during operation.
CAUTION
Machine installation environment
Comply with the recommended machine installation conditions
(such as room temperature, humidity or temperature of spindle
coolant water and wheel coolant water). If the machine is installed in
an environment that does not conform to the installation conditions
recommended by DISCO, rust formation may occur due to moisture
condensation or other factor, thereby adversely affecting the cutting
accuracy.
For the recommended environmental conditions, see the section
C-1, [Installation Specifications and Environment] of Installation
Manual.
NOTICE
- Responsibility for instructing workers
Instruct the operators and data maintenance personnel to read the
safety precautions set forth in the Data Maintenance Manual before
proceeding to work.
Also, if the worker performs various tasks, direct them to read the
points of note concerning the safety given in the respective
manuals.
The written instructions for this machine are Installation manual,
Operation manual, Data Maintenance manual, Maintenance
manual and Technical Reference.
- Responsibility for instructing workers who don't seem to understand
