You may only use mineral hydraulic fluids meeting the demands of DIN 51524. KTR
recommends those fluids corresponding to DIN 51524-3.
KTR recommends the following fluids (other manufacturers may be selected):
Manufacturer
Standard
Special
Mineral oil
- 20 °C to + 40 °C
(- 4 °F to 104 °F)
+ 10 °C to + 60 °C
(+ 50 °F to + 140 °F)
- 30 °C to + 20 °C
(- 22 °F to 68 °F)
+ 30 °C to + 70 °C
(+ 86 °F to + 158 °F)

The permissible operating temperatures of brake components from - 20 °C to + 60 °C (- 4 °F
to + 140 °F) have to be observed. For deviating operating temperatures please consult with
KTR.
Viscosity
We would recommend a viscosity range from 20 to 220 mm
2
/s (cSt) of the hydraulic fluid with operating
temperature. The viscosity during starting should not exceed 500 mm
2
/s and the viscosity during operation should
not fall below 12 mm
2
/s.
Filtration
When filling and re-filling the hydraulic system and replacing the hydraulic fluid, the oil needs to be filtered. For
that purpose use an offline filter or a respective fill unit. In addition we would recommend to use an inline filter.
The service life of the brake system is extended depending on the degree of purity of the oil.
As a standard the KTR basic power packs are equipped with a 10-µm-inline filter.
In order to ensure the reliability of the system, only those oils originating from the following purity classes are
permitted:
•
ISO 4406, class 20/17/12
Maintenance operations on the hydraulic system
In order to ensure a smooth operation of the overall system, the maintenance operations on the hydraulic system
(inspection of level and degree of dirt, replacing the hydraulic fluid or filter elements, etc.) have to be performed as
per the manufacturer's operating instructions.
The system has to be scavenged or vented after each replacement of the hydraulic fluid.
!
Adverse reactions may be generated by mixing different fluids or fluids of various
manufacturers.
Please contact the manufacturer of mineral oils if you intend to replace the hydraulic fluid.
