10.2 Preventative service
10.2.1 Care regulations
The exterior of the equipment is to be cleaned from time to time in order to protect it from
external corrosion. Oil is to be applied to the metallic surfaces.
10.2.2 Function and load test
If there is any doubt regarding the safety or reliability of the equipment, a function and load
test must also be performed.
LUKAS offers appropriate test equipment to this end.
10.2.3 Changing the hydraulic fl uid
- The hydraulic fl uid must be changed after the equipment has been used approx. 200
times / after three years at the latest.
- It must always be changed whenever the hydraulic fl uid for the accompanying pump
(motor / hand pump) is changed. This is to prevent the fresh hydraulic fl uid from becoming
contaminated by the used fl uid from the rescue equipment.
Procedure:
1. Completely retract rescue ram.
2. Change the hydraulic fl 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 directly into the pump:
completely unscrew the connection nut of the connection piece of the blue return
hose.
- 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 returnhose on the mono-coupling
(male).
- when the hose connection is via quick-connect-coupling to the pump:
completely unscrew the connection nut on the quick-disconnect-coupling of the blue
return hose.
4. Put the return hose into a separate collecting basin for the hydraulic fl uid still in the
equipment.
5. Slowly extend the rescue ram (the pump must be working during this time). The old
hydraulic fl uid from the ring space side runs via the return hose into the separate collecting
basin, and is to be disposed of in the same manner as the old hydraulic fl uid of 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 directly into the pump:
screw the connection nut of the connection piece of the blue return hose back on.
(Please observe the necessary torque of M
A
= 40 Nm!)
- 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 connection nut back onto the quick-disconnect-coupling of the blue return
hose.
(Please observe the necessary torque of M
A
= 35 Nm!)
8. Deaerate the rescue ram as described in the chapter “Preparatory measures”.
