3-5 Air Compressor Unit Usage Instruction
1) The pressure source of this machine’s pressure pipeline goes through the air pressure preparation
unit, and the pressure is set to 6kg/cm
2
. When the pressure source is less than 5kg/cm
2
, and the
duration lasts more than 2 – 3 sec, NC will turn on the alarm, and CRT will display 1011 AIR
PRESSURE LOW. In this case, check the pressure source and then press the RESET button to
continue the operation.
2) Maximum pressure: 10kgf/cm²
3) Adjustment range: 0.5 ~8.7 Kg f/ cm²
4 ) Filter size
：
5 μ
5 ) Recommended lube oil
：
ISO VG32
6) The pressure source should not be lower than: 5.5kgf/cm²
7) Although the air compressor preparation unit of the water filter has an automatically water
drainage, the machine operator should check whether there is any water accumulation at the shift or
at the end of the day. If the water drainage function is abnormal, water vapor may get into the air
compressor component, thereby reducing the lifespan. For the water drainage function of the filter to
be more effective, water in the air tank of the air compressor should fully drained out. It is also
recommended to install a dehumidifier at the pressure source to make sure that the air is dry.
8) The machine operator should pay attention to whether the pressure pipeline is making a bz kind of
noise. This may be due to gas leakage at the connector. Check the machine by tracing the noise.
The pipeline of this machine is connected by connectors, and the disassembling method is
described below: The nylon tube can be directly inserted into the connector. Use the finger or a flat
screw driver to secure the connector when pulling out the nylon tube.
Use a screwdriver or fingers to press down the fixing ring.
