a.Close drainage valve (See Fig.1-14)and air supply value (Fig.1-4). Check if the reading of pressure gauge (Fig.1-14 ) is below 6 bar. Turn the operation handle of pressure switch to “ON” (Fig.1-9 ) the machine will start immediately. The reading of pressure gauge will slowly rise with increasing pressure inside the air tank. When the reading of pressure gauge reaches 8 bar, pressure switch activates, the power supper is cut off, machine stops running. At the same time the solenoid valve(See Fig.1-11) activates to release high pressure in the cylinder of compression machine so that the machine can be started again; b.During the period when the machine stops running observe if the reading of barometer is decreasing. If there is no leakage of air in the machine, open air supply valve to begin supply of compressed air. When the pressure in the air tank decreases to 6 bar, pressure switch resets and power supply resumes, the machine starts running again. The pressure in air tank increases again. If the machine can automatically stop and start, the machine works normally.
