Тохиргоо
- Төхөөрөмжийг задлах: Carefully remove the AUTOOL AST 603 and all accessories from the packaging.
- Гэмтлийг шалгах: Check the device and all components for any signs of shipping damage. Do not use if damaged.
- Ажлын талбайг бэлтгэх: Ensure a clean, well-lit, and well-ventilated area. Position the vehicle on a level surface and engage the parking brake.
- Эрчим хүчийг холбох: Connect the power cable to the device and then to a standard AC 110V power outlet.
- Initial Purging (First Startup): For the first use, it is essential to fill the equipment's tubing with new brake fluid to achieve an air-free bleeding process. This purges any air from the internal lines of the AST 603 itself.
- Тохирох адаптерийг сонгоно уу: Choose the correct adapter for your vehicle's brake fluid reservoir. The kit includes adapters for various vehicle models, including Mercedes-Benz, BMW, Volkswagen, Skoda, Volvo, Land Rover, Jaguar, Ford, Audi, Tesla, and more.

Ашиглалтын заавар
The AUTOOL AST 603 allows for efficient, one-person brake fluid exchange without the need to press the brake pedal.

Figure 7: Visual guide for the brake fluid exchange process.
- Prepare New Brake Fluid: Place the pressure balance hose and the oil suction hose into the new brake fluid bottle. Ensure the bottle is stable.
- Connect to Reservoir: Connect the filling hose to the adapter fitting, then securely attach the adapter to the vehicle's brake fluid reservoir. Ensure the machine's internal lines are purged before connecting to the vehicle.
- Connect Recovery Bottle: Connect the recovery fluid bottle (waste oil bottle) to the brake wheel cylinder bleed screw.
- Үйл ажиллагааг эхлүүлэх: Turn on the power switch on the AST 603. Press and hold the "START" button to begin the brake fluid exchange operation.
- Даралтыг хянах: Adjust the pressure using the pressure adjustment knob as needed (0.7-2.5 bar). Monitor the pressure gauge to ensure stable operation.
- Monitor Fluid Level: The device features smart liquid level monitoring. Filling automatically stops when the new fluid bottle is empty, preventing air from entering the brake system lines.
- Drain Old Fluid: Open the bleed screw on the wheel cylinder to allow the old brake fluid to drain into the recovery bottle. Continue draining until new, clean brake fluid emerges.
- Бүх дугуйнд давтана уу: Repeat the process for each wheel, typically starting with the wheel furthest from the master cylinder (e.g., rear passenger, rear driver, front passenger, front driver).
- Үйл ажиллагааг дуусгах: Once all wheels are bled, close the bleed screws, turn off the AST 603, and disconnect all hoses.
- Шингэний түвшинг шалгах: Verify the brake fluid level in the vehicle's reservoir and top up if necessary.

Figure 8: The smart liquid level monitoring system ensures automatic stop when fluid is low.
The AST 603's pulsating brake fluid exchange technology effectively avoids the generation of air bubbles during the filling process, optimizing or eliminating the need for manual air bleeding.
