1. Check the oil level in the hydraulic reservoir; add oil as necessary.
2. Push and release the brake pedal many times with the engine stopped to remove all hydraulic pressure from the brake system until there is no pressure on the pedal.
3. Install two 207 bar (3000 psi) pressure gauges to front and rear hydraulic brake accumulator test ports, refer to page 7 for the locations of the test ports.
4. Make sure that the pressure gauge hoses are long enough so the gauges can be read while sitting in the operators seat.
5. Start the engine. Run the engine at low idle while reading the pressure gauges. The alarms (buzzer, master warning light and brake pressure warning light) should shut off when the accumulator with the lowest pressure reaches 106 to 115 bar (1530 to 1670 psi), approximately 40 seconds at any engine speed.
6. After the alarms stop, run the machine at high idle to finish charging the accumulators. The pressure must increase on both gauges until 190 to 196 bar (2757 to 2843 psi) is reached. This is the accumulator valve cut-out pressure. It is normal for the pressure to drop slightly once the cut-out pressure is reached.
7. With the engine running at high idle, push and release the brake pedal rapidly while reading the drop in pressure on the gauges. The pressure drops may not be equal, but as the lowest pressure reaches 157 to 167 bar (2280 to 2420 psi), the system pressure must start to increase. This is the valve cut in pressure.
