Flushing - Refilling or Changing the Hydraulic Fluid
1. Connect the bleed hose assembly (1) to the priming port and a bleed hose to the pressure
port as shown below:
Figure 9 - 3: Flushing/Filling Connections
2. Fill the priming fluid container with clean hydraulic fluid of the required type. Use the priming
pump (2), to pump fresh hydraulic fluid through the system until clean hydraulic fluid, free of
air bubbles, emerges into the container at the output port. Discard the contaminated fluid
expelled during this process.
3. Remove the bleed hose assembly (1) located to the output port and, to prevent the ingress
of any contaminant, fit a blanking plug in its place.
4. Close the isolation valve (4) and remove the bleed hose assembly (1) from the priming inlet.
5. Clean off any surplus oil that may have spilled onto the instrument casing.
The instrument is now ready for operation or storage. If storing, apply a label detailing the type of
hydraulic fluid contained in the instrument.
Note: For long term storage, it is recommended that the instrument be drained and stored empty.
