Safety items for greasing the push-pull axis (Continued)
CAUTION
- If the axis does not move for a long time after being greased, the
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.
- In a greasing operation, it is necessary to raise or lower the upper
and lower arm, using the I/O CHECK screen.
- When lowering the arms, be sure to move down the lower arm
first. If the upper arm is lowered first, it will contact with the lower
arm and could be broken.
- When raising the arms, be sure to move up the upper arm first. If
the lower arm is raised first, it will contact with the upper arm and
couldbebroken.
- Do not move the upper and lower arms back and forth while they
are lowered. The arms could be broken.
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.

toppled by the earthquake or like that.
After taking off the cover for maintenance purposes, store it
sufficiently away from the working area.
