WARNING

If any touch panel control is inadvertently activated during

maintenance or inspection, unexpected machine operation may

cause death or serious injury.

While you don't use the touch panel, press the Disco's logo button

located at the upper left of the screen in order to lock up and

deactivate the touch panel.

CAUTION

When you perform maintenance with the partition removed, observe

the following precaution. If you stand the removed partition against

the earthquake or like that.

After taking off the partition for maintenance purposes, store it

sufficiently away from the working area.

Safety items for greasing the Y-axis (Continued)

CAUTION

If an axis is not operated for a long time after greased, the applied

grease will harden. This could adversely affect the precision of the

machine, such as a position error during axis operation.

Do not perform greasing before a long-term operation suspension.

NOTICE

- If the areas to be lubricated are dark due to the environmental

conditions, confirm the nipple locations and cleaning areas with a

flashlight or the like to ensure proper lubrication.

- Neither safety goggles, protective gloves, stepstools, flashlights nor

alcohol, all of which are necessary for maintenance work, are not

supplied with the machine. Use what are furnished in your factory or

what comply with your factory's standards.
