General Information

In the case the brake / clutch pedal becomes soft or the operation activity of the brake / 
clutch pedal is to long it is needed to vigorously pump the pedal and repeat
the bleeding procedure again.

Adjusting the proper bleeding pressure

The pressure is adjusted at the factory to 2 bar. This guarantees that master
cylinder reservoirs are not warped or deformed with too much pressure. This
also keeps the outer boots or dust seals from leaking.
In case less pressure is required to bleed certain systems, turn  the
hand knob CCW to decrease pressure. In case higher pressure is required,
the pressure can be increased by turning the pressure regulator knob CW to the 
desired pressure.

Attention!

After changing the pressure adjustment of the bleeding unit, readjust it back
to the factory setting of 2 bar.
