10.2.5 Replacingthehydraulicuid
- Change the hydraulic uid after approximately 500 operating hours, and every two years
at the latest.
- It must always be changed whenever the hydraulic uid for the accompanying pump
(motor / hand pump) is changed. This prevents the fresh uid from being contaminated by
the used uid from the recycling unit.
Procedure:
1. Close crusher arms (until the tips are almost touching).
2. Change the hydraulic uid of the pump. Please observe the separate operating instructions
for the pump being used!
3. Screw off the return hose on the pump:
- when the hose connection is via mono-coupling to the pump:
remove the cover from the mono-coupling (male).
completely unscrew the connection nut of the blue return hose on the mono-coupling
(male).
- when the hose connection is via quick-connect-coupling to the pump:
Release the union nut on the hose completely from the plug connector nipple on the
blue return ow line.
4. Put the return hose into a separate collecting basin for the hydraulic uid still in the
equipment.
5. Slowly open the crusher arms on the tool (the pump must be working during this time).
The old hydraulic uid from the ring space side runs via the return hose into the separate
collecting basin, and must be disposed of in the same manner as the old hydraulic uid
from the pump.
6. Switch the pump off (motor pump) / no longer activate it (e.g. hand pump).
7. Reconnect the return hose to the pump:
- when the hose connection is via mono-coupling to the pump:
screw the connection nut of the blue return hose back onto the mono-coupling (male).
(Please observe the necessary torque of M
A
= 40 Nm!)
Pull back the cover on the couplings as far as the limit stop.
- when the hose connection is via quick-connect-coupling to the pump:
Screw the union nut on the hose on the plug connector nipple on the blue return ow line.
(Please observe the necessary torque of M
A
= 35 Nm!)
8. De-aerate the recycling unit as described in the chapter “Preparatory measures”.
