Changing Brake Fluid On Vehicle; Changing Original Brake Fluid Container - LTR BSG V4 Notice D'utilisation

4. Changing brake fluid on vehicle

CAUTION:
•
– Pulling the pressure regulator knob (4) unlocks it. The operating pressure can then be set in accordance with the
manufacturer's information by turning the knob. Then lock the knob again by pressing it.
– For vehicles with an electrohydraulic brake (Mercedes/Toyota), it is temporarily necessary to reduce the working
pressure of the BSD (Brake Service Device).
– Here the device automatically switches off. By holding down the start button, the vehicle can continue to be
ventilated in this case. In this situation, however, the automatic shut-off is bypassed with an empty drum.
– Supply the unit with the voltage appropriate for the unit model (12 VDC, 115 VAC, 230 VAC).
– Remove the sealing cap from the reservoir in the vehicle.
– Mount a suitable B-adapter on the reservoir.
– Connect the filling hose (10) to the mounted B-adapter.
– Set the switch (7) to the position <ON>.
– Press and hold the <START> button until the pump builds up pressure and continues running automatically.
– Now the prescribed quantity of brake fluid can be removed at the brake cylinders.
– After changing the brake fluid, switch off the unit by setting the switch to <OFF>.
– The unit generally depressurizes itself. However, if the pressure has been reduced during operation, a residual
pressure remains in the unit. This is released by turning the pressure regulator (4) all the way to the „Minus"
position.
– Disconnect the filling hose (10) and remove the B-adapter.
– Close the vehicle reservoir again with the sealing cap.

5. Changing original brake fluid container

– The unit is equipped with an automatic switch-off function when the original brake fluid container is drained.
– The unit must be bled again when the container is replaced.
– The procedure for bleeding is the same as that described in Point 3 Initial operation.
Attention: However, the return hose (2) must be inserted in the original brake fluid container.

The safety precautions in the section „Point 2 Safety instructions" must always
be strictly adhered to. Before beginning work, be sure to observe the infor-
mation on the maximum filling pressure and special working instructions of the
vehicle manufacturer. The pressure regulator (4) is set to an operating pressure
of 2 bars at the factory.
