Disposal or recycling of components containing mercury
NOTICE
This product has a fluorescent lamp that contains mercury. Disposal may be
regulated in your community due to environmental considerations. Please dispose of
or recycle it in conformity with the laws or regulations of your country, or contact your
local authorities for more information. And information posted on Panasonic group
Web site can be a good reference as well.

Repairs on or disposal of the linear motor
Make repairs on or dispose of the linear motor appropriately after fully understanding the
following matters.
1.
You are prohibited to remove or disassemble the linear motor on your own.
Using a special jig, trained personnel have to disassemble or dispose of the linear motor.
Please entrust to a waste disposal expert or contact us.
Precautions
• The stator produces the attractive force, which the mover lacks.
•
The attractive force generated by the stator (permanent magnet) is 2,200N for X-axis and
5,600N for Y-axis. It is strong enough.
Once one stator is stuck to another or a thick steel sheet, they cannot be detached from
each other easily.
•
A magnetic body (e.g. tool, jig, or bolt), such as iron, or a device, including a watch,
cellular phone, or magnetic card, should be kept 40 mm away from the linear motor.
Failure to do so can result in serious injury when the stator attracts the magnetic body and
then your finger or hand is caught between them.
Also, the strong magnetic force may damage the watch or the cellular phone and destroy
the data on the magnetic card.
2. Submit copies of this page and the next page to a waste disposal
expert when disposing.
When disposing of the linear motor, the waste disposal expert has to be informed of the disposal
procedures to prevent a waste disposal accident.
Some waste disposal experts may not handle the disposal of linear motors. In such a case,
please contact us.

Safely dispose of the linear motor after fully understanding the following matters.
1.
Procedures for removing and disposal of the linear motor
1) To prevent fire, remove combustible materials, such as resin parts or wirings, near the linear motor
before you apply heat to the linear motor.
2) Demagnetize the linear motor.
Evenly apply heat to the surface of the linear motor’s stator (permanent magnet) with an acetylene
gas burner for more than five minutes, with the surface temperature kept at approximately 1,000°C.
3) Confirm that the magnetic force is reduced.
Confirm that the magnetic force is 10 mT or less, or check to see whether the steel scale is not
strongly attracted.
4) After confirming that it has been demagnetized, dispose of it as industrial waste.
