Orientation
To ensure trouble-free operation, periodic checks of the oil level are necessary. The
fill level must be between the upper and lower marks on the oil sight glass.
Only use hydraulic fluid grade 15/13/10 in accordance with ISO 4406.
Viscosity other than 32 according to DIN ISO 3448 is not admissible.
For all work in connection with operating materials, the information in
the data sheets of the respective manufacturers and the information
in the document Notes on Operating Materials must be observed.
Example: Hydraulic unit G220 G420
a Filler neck
b1 Heat exchanger (hydraulic unit HLP32)
b2 Heat exchanger (spindle unit HLP5 (VG5))
c Fill level indicator
d Monitoring (level and temperature)
e Accumulator drain valve
f Monitoring (system pressure)
g Shut-off valve (cooling - water side)
h Return flow (cooling - water side)
i Inlet flow (cooling - water side)
j Oil drain plug
X Hydraulic fluid filter hydraulic fluid HLPD32 (VG32)
Y Filter bowl
Screws on the hydraulic system, the connected components, and the
supply lines must be tightened to the manufacturer's specified
torques.
