Hydraulic system
Adding hydraulic fluid:
– For refilling hydraulic fluid, unscrew the black filling cap (bleeding head) (2) from
the lid of the oil tank.
– When you open the filling lid for the hydraulic fluid, then it is possible that you hear
a 'hissing' sound. This sound is normal.
The filling lid (ROPA item no. 270070000) (2) is both a filler and vent filter. It main-
tains the required air balance as the fluid level varies (e.g. due to the fluid tempera-
ture).
Replace it as soon as it becomes dirty, but no later than every 2 years.
ADVICE
When using a vacuum pump, do not set a vacuum on more than 0.2 bar.
7.3.2.1 Hydraulic fluid change
The hydraulic fluid must be changed annually – best shortly before start of the season.
For this purpose, provide a barrel of sufficient size. Use the fluid drain hose provided
to change the hydraulic fluid. Screw the oil drain hose onto the drain valve (1) in the
bottom of the hydraulic fluid tank. The valve opens and the old oil drains.
ADVICE
The entire machine contains more than twice as much hydraulic fluid as can be
drained during a hydraulic fluid change. For this reason it is essential to adhere
strictly to the prescribed intervals for changing the hydraulic fluid.
