OPERATING Exchanging brake fluid
The safety instructions in the section "Safety Informations" must be strictly observed.
•
Before starting any work, please note the instructions for the vehicle manufacturer for the
•
maximum filling pressure and any other specific instructions.
• In general, always follow the recommended instructions and guidelines for bleeding the brake
system as mandated by the manufacturer for each type of vehicle.
• Factory settings for the pressure regulator are set to 1.6-2.0 bar. This ensures that the brake fluid
reservoir will not become deformed and that no leaks occur at the secondary cuff. Bleeding or
exchanging brake fluid with a lower or higher working pressure can be adjusted using the
pressure regulator (Max. 3.0 bar).
1. lnstall the supplied adapter, or the appropriate adapter according to the instructions on the brake
fluid reservoir.
2. Connect the filling hose to the already installed adapter.
3. Supply power to the brake maintenance device and turn the "ON/OFF" switch ON.
4. Press the "Start" button and hold until the pressure is at least 1.0 bar. The operating pressure can
be adjusted with the pressure regulator.
5. With the pressure built-up successfully, release the "Start" button and the brake maintenance
device will still work. With the pressure built-up unsuccessfully, release the "Start" button and the
brake bleeder device will stop working immediately. Possible cause: New brake fluid in the
container is not enough. The pressure is set too low by the pressure regulator.
6. Check that the adapter is correctly seated and tight where it connects to the brake fluid reservoir.
lf brake fluid leaks, immediately switch off the brake maintenance device and find the cause.
7. Now bleed the brakes, one-by-one, beginning with the back right brake and finishing with the
front left brake. To do this, open the valve on the wheel brake cylinder. Catch the old brake fluid
with the collection bottle. As soon as the new, bubble-free brake fluid begins to flow out of the
drain hole, the valve can be closed again.
8. Then turn the "ON/OFF" switch OFF, to stop the brake maintenance device working.
9. On the pressure gauge check that the pressure has gone down to 0 bar.
Note: Usually the brake maintenance device automatically gets rid of the remaining pressure.
However, if during the refilling process, the pressure was regulated lower, there will still be pressure
remaining. The pressure does not go down to 0 bar. The pressure regulator must be unloaded first.
After turning off the device, turn the pressure regulator to the right until the release point for the
remaining pressure is reached. The working pressure drops to 0 bar.
10. Uncouple the depressurized filling hose from the adapter. Remove the adapter from the brake
fluid reservoir.
lmportant: After completing the bleeding process or exchanging brake fluid, should the operation of
the brake or clutch pedal be too long or the pressure behind the operation be to "soft", repeat
depressing the pedal several times, each time applying strenger pressure to the pedal or clutch. lf the
situation remains unchanged, the bleeding procedure needs to be carried out again.
