ATTENTION!
Always replace the hydraulic fluid over a liquid collection container and dispose
of the collected fluid in a proper manner.
ATTENTION!
The hydraulic fluid must be completely replaced if the application conditions
(ambient temperatures) change substantially. When selecting a suitable hydraulic
fluid, please refer to the chapter “Recommended hydraulic fluids”.
9.2.3 Replacing the hydraulic fluid
- The hydraulic fluid must be replaced after approx. 200 deployments, but after three years
at the latest.
- It must always be changed whenever the hydraulic fluid for the accompanying hand pump
is changed. This is to prevent the fresh hydraulic fluid from becoming contaminated by the
used fluid from the rescue equipment.
Procedure:
1. Retract the cutter fully and depressurise the hydraulic system.
2. Remove the coupling on the cutter.
3. Drain off the hydraulic fluid.
4. Flush
5. Reassemble the coupling.
6. Connect hand pump with fresh hydraulic fluid.
7. De-aerate as described in Chapter “First operation”.
8. Re-connect the hand pump.
