5. The unit is not ready for operation even when the reading on the pressure gauge drops to 0 bars. There
are no more bubbles in the unit on the pressure side.
Installing adapter
Screw the adapter included onto the thread (D 43mm) on the brake
fluid reservoir or install the appropriate adapter (see adapter list)
as specified in the instructions on the brake fluid reservoir.
Operating instructions
Observe the safety precautions in the section "For your safety" strictly.
Before starting work observe the vehicle manufacturer's instructions regarding the maximum filling
pressure and special operating instructions.
The pressure regulator is set to an operating pressure of 2 bars at the factory. This ensures that the
compensation reservoir is not deformed or the secondary seals damaged resulting in leakage. The unit can
easily be set to a lower or higher operating pressure, if required to bleed the brakes or replace the brake fluid.
Work steps
1. Connect filling hose 1 to the adapter already installed.
2. Move power switch 5 to <<ON>> position.
3. Press start button (pump runs slightly louder at first, because no fluid is being pumped; later it hums
pleasantly.).
4. The pump builds up the operating pressure (max. 3.5 bars). This can be adjusted with pressure regulator
3 by pulling out the control flap and turning to the desired operating pressure (Recommended pressure:
2 bars).
Bleeding operation
6. Now bleed the brakes in sequence beginning at the right rear and finishing at the front left brake. For this
purpose open the valve on the corresponding wheel brake cylinder. Catch the old brake fluid in a catch
bottle. As soon as the new brake fluid exits from the drain hole without bubbles, close the valve again.
As a matter of principle always observe the instructions and guidelines for bleeding the brakes
specified by the manufacturer for the specific vehicle model.
7. After completion switch off the unit (move power switch 5 to <<OFF>> position).
8. Note: As a rule the unit relieves any pressure present. However if the pressure was reduced during the
filling operation, the pressure is not relieved. This means that it does not decrease to 0 bars. In this case
it is first necessary to relieve the pressure in the pressure regulator. To do this switch off the unit and turn
the pressure regulator to the right until the pressure is relieved. The operating pressure then drops to 0.
9. Filling hose 1 is no longer under pressure and can be disconnected from the adapter (no pressure, no
squirting).
10. The brake fluid reservoir is not filled up to the top. Use a suitable pipette to remove excess brake fluid
down to the permissible fill level (see Fig. )
11. Remove adapter and seal brake fluid reservoir.
Important! As a matter of principle always observe the instructions and
guidelines for bleeding the brakes specified by the manufacturer for the
specific vehicle model.
Care and Maintenance
- Disconnect electrical power plug before any type of work on the unit.
- Always keep unit clean.
- Never clean the unit with a steam pressure cleaner.
