level) – prevents the oil tank from inflating.
• Pre-tension of the oil tank to the specified overpressure -> supports the variable
displacement pump's suction
• Filtering the intake air
• Opens at 0.4 bar (5.8 psi)
The breather filter is located in the machine at the rear right.
Replace the filter as indicated in the maintenance plan!
