Environmental Conditions
• Use clean, oil-free air (dew point below -15, residual oil: 0.1 ppm, and filtration rating: 0.01μm/99.5 % or more). • Keep room temperature fluctuations within ±1ºC of the set value (Set value should be between 20ºC - 25ºC), indoor humidity no more than 80% and no condensation. • Keep cutting water and cleaning water 2ºC above room temperature (fluctuations within ±1ºC). Keep temperature of cooling water the same as room temperature. • The machines should be used in an environment, free from external vibration. Do not install machine near a ventilation opening, heat generation equipment or oil mist generating parts. • This machine uses water. In case of water leakage, please install the machine on the floor with sufficient waterproofing and drainage treatments. • Please follow the product manual of our company.
