    ……………………………………………………………….………………………… Vacuum line Open all valves of the vacuum-pressure system. • Open all gate valves and remove any possible obstacle from the line. • PRECAUTIONS WHEN STARTING THE SYSTEM Check oil levels in gearbox and side mounted tank. Check that all protection devices are correctly installed. Check that there are no obstacles in the vacuum line.

  • Page 16: Ordinary Maintenance

    ……………………………………………………………….………………………… WARNING Rotation speed. Once the needed vacuum rate has been reached, we recommend reducing the vacuum pump speed to its working speed (see paragraph “Usage limitations”): this allows keeping the achieved vacuum/pressure rate constant. The pump speed can also be reduced to values lower than the working speed during the tank discharging phase (with the 4-way valve in pressure mode) without increasing the draining time.
