9.2.1 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.
9.2.2 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.
9.2.3 Changing the hydraulic fl uid
- The hydraulic fl uid must be changed after 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. Change the hydraulic fl uid of the pump. Please observe the separate operating instructions
for the pump being used!
2. Screw off the return hose on 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).
3. Put the return hose into a separate collecting basin for the hydraulic fl uid still in the
equipment.
4. Activate the hydraulic pump and pressurize the supply hose. Pressurize the supply hose
as long as it needs to scavenge the whole used hydraulic fl uid out of the hose reel.
The period of pressurization depends on the length of the hose assemblies (Fluid volume
in the hose reel) and the fl ow rate of the pump. You will fi nd the fl uid volume of the hose
reel in the chapter ‘technical data’.
5. Switch the pump off (motor pump) / no longer activate it (e.g. hand pump) and dispose the
collected hydraulic fl uid properly and according to the legal specifi cations.
6. Reconnect the return hose to the pump:
screw the connection nut of the blue return hose back onto the mono-coupling (male).
(Observe the necessary torque of M
A
= 35 Nm/25.8 lbf∙ft!)
Pull back the cover on the couplings as far as the limit stop.
7. Check and top up the hydraulic fl uid level in the hydraulic pump.
