*Pay attention to the ambient temperature when starting up the compressor. If the ambient temperature is lower than the minimum temperature specified in the manual, a heating device should be equipped.

   * High viscosity at low temperatures will reduce the passing ability of the oil filter, thus making the compression chamber of the micro-oil compressor in the initial stage of the start-up of the oil volume is small; it is recommended to use the original lubricating oil, it is recommended to appropriately increase the frequency of replacement of oil filters in low-temperature environments, and for long-term shutdowns after start-up of the low-temperature environment, the oil filter should be replaced.

   * Low temperature caused by the increase in condensate during operation, timely oil analysis to monitor changes in water content.

   *Micro-oil air compressors equipped with heat recovery system should cut off the oil valve connecting to the heat recovery system before starting the machine; after the compressor is loaded normally, then open the valve to switch to the heat recovery state.
