Mori Seiki CNC Turning Center NL2500MC/700

Note: Oil replenishment is possible even while the machine is operating. But oil supply will stop during replenishment, and if the oil supply stops for a long period, the mist will also stop. So finish replenishment quickly if it is being done while the machine is operating.

Note: The internal pressure is released when the fill port cap is loosened.

Oil supplied from a bottle containing the designated oil, 'ULTIMA' plant-derived lubricant for mist made by TANAKA IMPORT GROUP

Caution: Use genuine 'ULTIMA' plant-derived lubricant for mist. Mori Seiki cannot accept any responsibility for trouble or problems such as fire, health problems, or machine damage caused by using an unauthorized oil.

If 'ULTIMA' is not available, select the equivalent product used

Caution: Do not mix in an oil different from the oil in current use. When changing to a different brand of oil, drain all the original oil from the tank completely, clean the inside of the tank, and then add the replacement oil. Mori Seiki is not responsible for problems arising from the mixing of different brands of oil or the use of non-specified oils.
