5.4 Hydraulic uids
The Hägglunds hydraulic system is primarily designed for operation with hydraulic
uids according to ISO 11158 HM.
Fluids by the standards given in Table 4 are suggested. Before the start of project
planning, see data sheet RE 15414, Hydraulic uid quick reference, for detailed
information on hydraulic uids and specic additional demands

Mineral oil based and
mineral oil related hydraulic
uids
Environmentally acceptable
hydraulic uids
Fire resistant hydraulic uids
Details regarding the selection of hydraulic uid
The hydraulic uid should be selected such that the operating viscosity in the
temperature range, as measured in the motor housing, is within optimum operation
range, see Fig. 4. General recommendation is to have a system temperature of
50°C, see dotted line in Fig. 4. A VG 68 uid will render just above 40 cSt at this
point.
• Optimum viscosity range is 40 to 150 cSt.
• Running above 150 cSt or below 40 cSt results in reduced efficiency.
• Running above 400 cSt results in substantial efficiency loss.
• For pumps, the maximum start-up viscosity is 1600 cSt.
• For motors, starting at above 10000 cSt imparts unnecessary strain on parts.
• Running below 30 cSt may impact the service life.
• Running below 20 cSt may render instant seizure.

5.5 Requirements for hydraulic uid cleanliness
The drive systems are equipped with a lter in the charge line. In order to
obtain stated service life it is important to follow recommendations concerning
cleanliness levels and maintenance.
Cleanliness level recommendations
• When lling the system with hydraulic uid it is important to ll through the
dedicated oil lling connection (see 8.2: Filling up the system with hydraulic fluid).
• For industrial applications the contamination level should not exceed ISO
4406:1999 18/16/13.
• Have a water content of <200 ppm (0,02%).
• Always use lter elements recommended and supplied by Bosch Rexroth.
• The hydraulic uid should be analysed according to the maximum intervals on
the maintenance chart (see Table 18: Maintenace chart). Be particularly careful
when removing equipment for repairs or maintenance, dirt must not be allowed
to enter the system, clean prior to opening and plug open connections.
NOTICE
Dirt in oil
Damage on equipment.

5.6 Drive system monitoring
The following function must be fullled in the system. See order specic
Hägglunds Fusion documention for the monitoring settings.
The monitoring of the drive system switches and sensors are grouped in two levels
according to Fig. 5.
The warning indication is to give an indication about a problem in the drive system
that does not need an immediate action.
The alarm indicates a need for stopping the pump. The stop sequence is to rst
stop the hydraulic motor by setting the pump swash angle to zero without ramp
to allow the hydraulic drive to stop and after a short delay switch off the electric
motor.
The low (charge) pressure indicator must be interlocked during stop and startup
of the electric motor to avoid alarm and give the pump time to build up the charge
pressure after start.
Note! For Fusion with pump control alarm and warning must be handled by
customer control system.
