Hydraulic pressure
operation (PV 623)
4.1 Introduction
Chapter 1 gives a description of the different parts of the
instrument:
to
This chapter gives examples of how to connect and use the
PV 623 pressure station to give the necessary hydraulic
pressure conditions.
Before you start:
•
Read and understand the “Safety” section.
•
Make sure that there is no damage to the instrument, and
that there are no missing items.
Note:
Use only original parts supplied by the manufacturer.
4.2 Fill the reservoir
Caution: Ice in the pressure mechanism can cause
damage. If the temperature is less than 4°C (39°F), drain
all water from the instrument.
The first time you want to use the hydraulic pressure station,
use this procedure to fill the reservoir:
After a period of operation, if it is necessary to add more fluid to
the reservoir, use this procedure again.
To add more fluid during a pressure procedure, refer to
Section 4.6.2.
To drain the hydraulic fluid, refer to Section 4.7.
