2. Remove the pressure release valve.
3. Use the refill bottle to add more hydraulic fluid to the reservoir. Do not put too much fluid into
the reservoir. Leave a small air gap at the top of the reservoir.
Note: To prevent contamination use only one type of hydraulic fluid in the pressure station.
4. Replace the pressure release valve. Turn fully clockwise until firmly shut.
5. Return to the procedure in Section
5.4.1.
5.6 Drain Hydraulic Fluid from Equipment Under Test
If additional hydraulic fluid was used during a pressure test, drain the excess fluid from the
equipment under test.
If it is safe and there is no risk of contamination, the hydraulic fluid can be left inside of the
equipment under test.
5.6.1 Preparation
To drain the equipment under test, the following items are recommended:
•
Applicable skin and eye protection.
• A sufficiently large container to hold the hydraulic fluid.
• Applicable materials to clean the pressure station, refer to Chapter 7.
5.6.2 Procedure
1. Release the pressure (Section 5.2).
2. Remove the equipment under test (Chapter 2). Do not let the hydraulic fluid spill onto the
PV 623G / PV 623 - IS.
3. If necessary, drain the hydraulic fluid from the equipment under test.
Note: To discard the hydraulic fluid, obey all the local health and safety procedures.
5.7 Drain Hydraulic Fluid from PV 623G / PV 623 - IS
In some conditions it is necessary to fully drain the hydraulic fluid from the PV 623G / PV 623 - IS
pressure station; for example:
•
When using water as the hydraulic fluid and the storage temperature is less than 4°C (39°F).
• Preparing the pressure station for a long period of storage.
• If there is contamination in the hydraulic fluid.
5.7.1 Preparation
To drain the pressure station, the following items are recommended:
•
Applicable skin and eye protection.
• A sufficiently large container to hold the hydraulic fluid.
• Applicable materials to clean the pressure station, refer to Chapter 7.
