・LED Safety Precautions
This unit incorporates LED for its lighting system. To use it safely, be sure to observe the
following precautions
CAUTION
CAUTION: Operations, controls, and adjustment other than described in this document may
cause hazardous radiant exposure.
1. The following standard has been established as safety standards for LED devices:
•EN62471: 2008 "Photobiological safety of lamps and lamp systems"
•JIS C 7550: 2011 "Photobiological Safety Of Lamps And Lamp Systems"
2. This product is classified as lower than the risk group 1.
3. Do not look into the LED light. (Never look into the LED light even if light is not emitted.)
4. Do not directly look at laser beam using an optical instrument (light condensing devices such
as magnifying glass).
5. Do not let the reflected light from the flat plane come into sight if the workpiece has a mirror
type surface.
6. Try not to gaze the measuring surface when measuring a surface that is easy to reflect.
7. Irradiation to the skin causes no problem.

Precautions for Use
● This unit is a hardness testing machine.
Do not use this system for any purpose other than such test.
● This system is a precision machine.
Exercise great care when handling this machine. Never bump or apply excessive
force to any of the parts during operation.
● Rectify the installation environments. (Refer to "2. Installation" for further
information.)
Free of dust and dirt
Free of vibration
Close to 23°C in ambient temperature
Free of extreme humidity
● Do not touch this machine during operation.
The unit is a motor-driven hardness testing machine. To prevent your hands or objects
being accidentally pinched during test, do not go near the machine while it is operating.
● Gently install the specimen stage.
If the specimen stage is subject to large impact, it could be damaged. Exercise great care
when putting a specimen on the stage.
● Pay attention to working clothes and shoes.
Wearing slippers is prohibited; make sure to wear safety shoes.
The heat radiated by the human body can influence measurements.
Also wear long sleeves to avoid abrasions, etc. by the edges of the workpiece.
● Be sure to turn off the power during connection and maintenance.
To avoid accidents or electric shock due to malfunction of the machine under operation, be
sure to turn off the power before performing connection or maintenance.
● Be careful of unexpected machine movement when replacing the specimen.
When replacing the specimen, exercise great care to avoid personal injury due to sudden
unexpected movement of the machine.

No. 99MBG127A
vii
● Power supply
The power supply specification of this machine
•Pollution Degree : 2
•Overvoltage Category : Ⅱ
•Class of equipment : Class Ⅰequipment
For information about other specifications, refer to “2.1.6 Power supply”
● Power cord
Only use the supplied power cord. If there is something wrong with the power cord or
power connectors, contact Mitutoyo. Defective parts should be replaced by a Mitutoyo
service engineer.
● Removing the cover and disassembling the machine
This machine is precisely adjusted, and is comprised of high-voltage parts. In order to
prevent accident and to maintain the performance, do not absolutely remove the cover on
the machine.
● Danger prevention
In order to prevent danger, do not use the machine in locations where volatile gases could
be generated.
● Maintenance
Gently wipe off dirt from the machine using a lint-free and soft cloth. If the dirt is difficult to
remove, wipe it clean with a cloth soaked in neutral detergent, then wipe lightly with a dry
cloth or a cloth well-wrung after soaking in water. Do not use organic solvents such as
thinner or benzine.
● Take special shielding measures when using the machine in the following
locations:
Where noise is generated due to static electricity
Near strong electric fields
Where power source lines pass nearby
Where the machine could be exposed to radioactivity
Where the machine could be subjected to corrosive gases
● Be careful of unexpected machine movement when replacing the lens or
specimen.
When replacing the indenter, lens, or specimen, exercise great care to avoid personal
injury due to sudden unexpected movement of the machine.

No. 99MBG127A

● Magnetism effect
The hardness testing machine may not provide proper test results due to magnetic
effect.
Keep a magnet (or a magnetized object) away from this unit.
(Especially because this unit has a mechanism that generates test force by controlling
electromagnetic force, a magnetic material can cause a problem with test force and
test operation.)
●Please do not carry the measurement thing of 18kg or more alone.
Please do not carry the measurement thing to exceed 18kg alone for safety.
●System Relocation
It is NOT strongly recommended that the system is relocated by a user him/herself.
Some impulse or vibration possibly occurring during relocation could cause a loss of
essential accuracy. In the case that the system is relocated, system accuracy needs
to be checked and adjusted.
If you desire to relocate your system, be sure to contact your dealer or the nearest
Mitutoyo sales office.
