. Operational Instructions 4.1 Power Supply 4.1.1 Connect the 2-prong power cord to the power outlet of the compressor (Figure 4.1.1). Becareful not to 3-prong power cord to the wall socket first. 4.1.2 Connect the 3-prong power cord to the 110-220V (AC) power socket (Figure 4.1.2). * Once the fan inserted into the power supply starts to turn, the buzzer prompts the sound to be emitted. The motor and fan of the compressor will not work. Figure 4.1.1 Figure 4.1.2 4.2 External 12V Battery 4.2.
4.3 Air-pumping Operation 4.3.1 Connect the power supply according to 4.1 power supply instructions for Power Supply Use or 4.2 Instructions of External 12V Battery Application. 4.3.2 Find out the position of the adjustable pressure gauge and set the ideal pressure value through the knob of the pressure gauge. A clockwise rotating pressure value increases and a counterclockwise rotating pressure value decreases. WARNING: The maximum pressure of this compressor is 300bar (4350psi).
5. Temperature Protection System 5.1 When the temperature is higher than 70°C, the machine stops automatically and alarms (high frequency sounds). And the fan continued to work. 5.2 When the temperature is below 45°C, the fan stops working. 5.3 You need to press the ON/OFF again to continue working. 6. Maintenance and Maintenance Methods 6.1 Lubricating Oil Refueling Operation Instructions 6.1.
6.3 Filter Element Replacement 6.3.1 Replacement of filter cotton in filter tank 6.3.1.1 Change every 40 cycles. First, it is required to release the air inside the machine. The pressure gauge reading is 0 psi/bar. Find the position of the filter tank at the bottom of the machine. Open the lid of the filter tank counterclockwise with a wrench. Take out the filter cotton with tweezers and replace it with new filter cotton. (Figure 6.3.1.1) 6.3.2 Replacement of filter cotton for flexible pipe 6.3.2.1 6.3.2.
6.4 Burst Disc Replacement Find the position of the burst disc, use the tool to rotate counterclockwise to remove the damaged burst disc, replace it with the same size (6K) burst disc, tight it clockwise, otherwise it will leak air (Figure 6.4). Figure 6.4 7. Troubleshooting 7.1 Compressor doesn’t work. Solution: Make sure that one end of the 3-prong power cord is plugged into a regular wall socket and the other end is plugged into the air compressor.
