The non-return valves in the hoses are integrated with the
quick-coupling’s and are opened by the pins located in the centre
of the male and female parts. If these pins get worn the coupling
must be replaced because of the risk of blocking.
·
In the high pressure hydraulic tool set it is recommended to
use a special hydraulic oil or in any case an oil with a
viscosity of about 12cSt at 20°C.
·
During the filling of the container of the high pressure pump
it is recommendable to couple the set according to scheme B,
Fig 07-25. Before filling, open the release valve (2) and empty
the cylinders (4) by pressing the piston and cylinder together.
After that, drain the oil and re-fill through the filling plug
(1).
·
After filling, vent the system by pressing in, with a finger,
the centre pin of the female part of the last quick-coupling,
the coupling being disconnected from the pressure gauge.
Keep on pumping until air free oil emerges from the coupling.
·
Check the pressure gauge of the hydraulic tool set regularly.
For this purpose a comparison pressure gauge is delivered.
This pressure gauge can be connected to the plug hole (7),
the outlet hose of the pump being connected direct to the
pressure gauges.
07.3.3.1 Instructions for high pressure hydraulic tools
Caution! Pay special attention to cleanliness and carefulness when
using and maintaining the hydraulic high pressure tools.
·
When the hoses are pressurised, any maintenance, adjust-
ments nor repairing are allowed, not even tightening of the
connections.
·
Before rising the pressure in the high pressure tool, all
hydraulic parts (pump, pipes, hoses, regulating units) has to
be vented.
·
The weakest parts maximum allowed pressure must not be
exceeded.
·
Keep a logbook or similar of the hydraulic tools.
