Care and Maintenance
9.3 Hydraulics
9.3.1 Special Safety Instructions
• Before working on the hydraulic system of the Big Pack Baler, reduce the pressure on the
hydraulic cylinders of the baling channel flaps.
• Check the hydraulic hoses and lines regularly and replace them if they are damaged.
• Spare parts must correspond to the technical requirements of the machine
manufacturer. For this reason, use KRONE original spare parts only.
• Repair jobs on the hydraulic system should only be performed by trained and authorised
professionals.
• When working on the hydraulic system, absolute cleanliness is essential.
• Check the hydraulic oil level each time before placing the machine in operation.
• Observe the intervals for replacing the hydraulic oil and hydraulic oil filter.
• Dispose of old oil properly.
9.3.2 On-board Hydraulic System
When the hydraulic oil is replaced, the
hydraulic cylinders must be retracted into
the baling channel flaps.
Pressure is supplied to the on-board hydraulic system of
the Big Pack Baler through its own hydraulic pump. It is
connected to the main gearbox by a flange and does not
require any maintenance.
The on-board hydraulic oil and the hydraulic oil filter must
be replaced at least once a year before the beginning of
the season. Have a suitable container on hand to collect
old oil when changing the oil. Loosen the drain screw (1)
on the storage tank (2) and unscrew it. After the oil has
drained out, screw in the drain screw again. Unscrew the
dipstick (3) and add an appropriate amount of hydraulic
fluid. Check the oil level with the dipstick (3). The
specifications of the hydraulic fluid are listed in the
Chapter “Technical data”.
The hydraulic filter (4) is located in front of the twine box
on the left side of the machine.
Filter replacement interval
• Before every season (at least once year)
• Relieve all pressure from the on-board hydraulic
system.
• Unscrew the filter housing.
• Replace the filter element.
• Screw on the filter housing.
• Check for leaks.
