4.20.7 Draining condensation water
After a long standstill period, drain any water
from the hydraulic oil box. To do this, use the
drain valve 1 (Fig. 4) at the underside of the
box.
- Remove the lock nut 1 (Fig. 4) from the
drain valve.
- Screw the drain hose 2 onto the valve
socket.
- The valve opens automatically.
If pure hydraulic fluid leaks, remove the hose
immediately and mount lock nut.
ATTENTION
Danger of unintentional draining!
- Check the fluid level.
4.20.8 Changing the hydraulic fluid
- Warm the hydraulic system up.
- Provide a waste oil receptacle.
- Due to the large quantity to be changed,
you should first pump out as much fluid as
possible via the upper cleaning opening.
To do this, we recommend that you use our
FLUSHING AND FILTRATION UNIT.
- Drain residual oil using the drain valve as
described above.
- Clean the box and replace the filter inserts
whenever you change the oil.
4.20.9 Cleaning the reservoir
In particular during long periods at standstill,
the hydraulic oil excretes dirt particles which
are deposited onto the bottom of the container.
Therefore during each oil change, check the
inner walls and bottom.
DANGER
Risk of explosion!
Do not use naked light!

Clean the oil reservoir as needed.
- Clean the area around the cleaning cover
(5) and remove cleaning cover 5 (Fig. 5).
- Remove the suction hoses of the hydraulic
pumps from the box and close them to
prevent dirt from getting into the pumps.
ATTENTION
Pumps can be destroyed!
- Clean the inside with flushing oil and a
lint-free cloth.
- Textile fibres and solvents are
enemies of the hydraulic system. Therefore,
do not use steel wool, diesel oil, petrol, etc.
for cleaning purposes.
