AST605 adopts the brand new pulse exchange technology, which continuously sends out pulse signals at certain time intervals to constantly deliver high-frequency pressure output to the brake fluid pipeline. The application of pulse in the brake fluid exchange machine solves the problem of air bleeding from the pipe, while the powerful impact also takes away the dirt and impurities adhering to the inner wall of the pipe, which both saves working time and improves efficiency.

Time-efficient & Pressure Adjustable

It changes the traditional way of exchanging the brake fluid by 2 people. One person can easily exchange the brake fluid in just 10 minutes, saving time and effort. AST605 adjustable pressure range is 0.6-3.0bar, which can adjust the pressure output according to the pressure resistance range of brake fluid reservoir of different models, making the operation more professional and easy.

Safe & Reliable Pressure Monitoring

AST605 comes with a built-in pressure monitoring device, when the pump pressure falls below 0.6 bar, it will start the automatic breaking protection to prevent air from getting into the brake fluid pipeline of the car, enabling a safer and more reliable working process.

Low working noise

The noise generated during use is less than or equal to 70 decibels, so as to protect your safety and health. No noise and enjoy a better working environment.

Wide compatibility

Suitable for most models in Europe, America, and Asia, for Dot3, Dot4, and Dot5.1 brake fluid standards.

Instruction of AUTOOL AST605 Brake Fluid Exchanger

1. Lift the car to the right height to suspend the wheels off the ground.
2. Connect the four oil bottles of the equipment to the car brake sub-cylinders, and loosen the outlet screw of the brake sub-cylinders to ensure that fluid can be flown out.
3. Put the inlet hose and pressure adjustment hose into the new brake fluid bottle
4. Connect the power supply and turn on the power switch.
5. Press the Start button to build up the pressure until the pointer of the pressure gauge exceeds 1 bar. At this time, you can release the button and adjust the pressure as needed.
6. Before replacing the brake fluid, the output hose must be exhausted first, and then find the matching model connector and connect it to the oil reservoir of the brake master cylinder.
7. During the fluid exchange, if the exchanging speed is a bit slow, the output pressure can be adjusted appropriately as required.
8. After the fluid exchange is completed, please turn off the machine and reduce the pressure to zero, then remove the connector attached to the car reservoir to prevent the excess pressure from causing an overflow of the brake fluid.

About pressure settings

The default working pressure of AST605 is set to 1~1.5bar, which can ensure that the brake fluid reservoir will not be deformed during exchanging the fluid, thereby securing the tightness of the secondary sealing ring. It is also possible to bleed or exchange brake fluid at lower operating pressure by adjusting the amount of pressure. Please pay attention to pressure adjustment during brake fluid exchange at higher operating pressures, because excessive pressure may damage the brake master cylinder of the brake system.

Precautions

• Do not mix DOT5 with DOT3 and DOT4 because the base oil composition differs. The bleeding sequence during fluid exchange needs to follow the principle of "far to near from the master cylinder or brake pedal". For left-hand drive vehicles, the order is "right rear wheel → left rear wheel → right front wheel → left front wheel", bleeding, in turn, to ensure that the discharge of clean fluid and no air bubbles.
• Please do not start driving immediately after the brake fluid exchange is completed, it needs to be checked to make sure there are no leaks in the pipeline. Start the vehicle, keep it idling in place and press the brake pedal to ensure that the pedal resistance gradually increases and that the brake fluid pressure is maintained. Then perform an internal road test to confirm that the braking performance is normal before driving on the road.
