2. Connect the air supply line, set the air pressure to 5 bar (72.5 psi), then start the pump.
3. In most cases air leaks will occur and the pump may not work. This is normal.
4. While the pump is running, gradually tighten the bolts (pos.21) on both sides, according to a cross
pattern*, until there are no more leaks.
5. Evenly tighten the bolts (pos.21) to the prescribed torque (see table 7), again according to a cross
