10.2 Preventative service
10.2.1 Note concerning care
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 Functional and loading 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 Replacing the hydraulic fluid
- The hydraulic fluid must be changed after the equipment has been used approx. 200
times / after three years at the latest.
- It must always be changed when the hydraulic fluid for the accompanying pump (motor/
hand pump) is changed. This ensures that the fresh fluid is not contaminated by used fluid
in the rescue tool.
Procedure:
1. Close blade arms (until the tips are almost touching).
2. Change the hydraulic fluid of the pump. Please observe the separate operating instructions
for the pump being used!
3. Screw off the return hose on the pump:
- if the hose is connected to the pump directly:
completely unscrew the connection nut of the connection piece of the blue return hose.
- if the hose is connected to the pump via a mono-coupling:
remove the cover from the mono-coupling (male).
completely unscrew the connection nut of the blue returnhose on the mono-coupling
(male).
- if the hose is connected to the pump using a plug coupling:
completely release the union nut of the hose line from the plug coupling nipple
of the blue return line.
4. Put the return hose into a separate collecting basin for the hydraulic fluid still in the equipment.
5. Slowly open the tool (the pump must be working during this time). The old hydraulic fluid
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 fluid 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:
- if the hose is connected directly to the pump:
screw the connection nut of the connection piece of the blue return hose
(Please observe the necessary torque of M
A
= 40 Nm!)
- if the hose is connected to the pump via a mono-coupling:
screw the connection nut of the blue return hose
(Please observe the necessary torque of M
A
= 40 Nm!)
Pull back the cover on the couplings as far as the limit stop.
- if the hose is connected to the pump using a plug coupling:
Screw the union nut of the hose line back onto the plug coupling nipple
of the blue return line.
(Please observe the necessary torque of M
A
= 35 Nm!)
8. Deaerate the rescue tool as described in the chapter “Preparatory measures”.
