AUTOOL AST612 Brake Fluid Change Machine 12V Vehicles Pulsating Brake Oil Exchanger TWO-WHEEL DIL EXCHANGE
The AUTOOL AST612 Brake Fluid Change machine uses microcontroller control to accurately manage brake fluid pressure and flow. It features a high degree of automation, allowing one person to operate it easily. The machine utilizes new pulse technology to provide output pressure to the brake fluid pipeline. This helps remove impurities from the pipeline and improves work efficiency.


- How To Adjust Working Pressure Correctly?
- When the device is out of the factory, the working pressure of the pressure regulator is set to 1~1.5 bar, to ensure that the liquid storage chamber does not deform while changing liquid, thereby ensuring the tightness of the secondary sealing ring.
- In addition, it is also feasible to exhaust or change the liquid at a lower working pressure by adjusting the pressure and the size switch.
In special circumstances, while operating under a higher working pressure, be aware of the excessive pressure adjustment, which may damage the brake master cylinder of the brake system. - Please check each connection if there is any leak when changing the oil, and whether the connecting hose is damaged, to keep the new oil filler port clean.
