Operating and Safety Instructions
Hydraulics
Before mounting the hydraulics these instructions must
be fully read and understood.
WARNING!
For safety reasons, it is important to take the
following precautions before working on the
valve or installation into the line:
1. Personnel to install and adjust the
hydraulics must only use the proper
tools and must wear (protective) clothing
required for the work area.
2. The personnel must be familiar with
the equipment and the operation of the
hydraulic control system, the immediate
environment of the equipment, the
safety devices and any emergency
measures required.
3. Before mounting the hydraulic actuators,
the pipeline must be made pressure less.
4. Only qualified and experienced
personnel are allowed to handle the
hydraulics.
5. During assembly/disassembly, the
hydraulics must remain pressure less
and the pressure reservoirs must be
discharged.
6. During assembly/disassembly of springloaded hydraulic actuators, the springs
must be released.
Storage / Protection / Suitability of the Hydraulics
Storage
When a hydraulic control system is to be stored for some time before being fitted, storage should
be in the original delivery crates, with any waterproof lining and desiccant in place. Storage
should be off the ground in a clean, dry, area. If storage is for a period longer than six months, the
desiccant bags (if supplied) should be changed every six months. If the hydraulics have been stored
for more than twelve months, they should be inspected by Sempell personnel before being fitted.
Protection
Hydraulic control systems are delivered with protection according to customer’s specification. Any
protective wrapping or covers should remain in place until the hydraulic control system is filled.
Suitability of the hydraulics
Check that the data shown on the identification plate of the hydraulics and the control device
correspond to the operating conditions. When in doubt, contact Sempell.
Working on the hydraulic control system
1.
The hydraulic unit and the control device must be assembled in the intended location. Hydraulic
actuators with oil sump must be mounted in the proper position on the specified valve.
2. Operating instructions must be available for reference at any time.
3.
Operating instructions as defined by local legislation or regulations must be available and must be
observed. Individual components should be easily accessible for checking and maintenance.
4. Any packing must be removed during mounting.
5. All work must be carried out by trained and qualified personnel only.
6. Operators must be instructed by experienced personnel before commissioning.
7. Protective caps and plugs required for transport are only to be removed immediately before
installation.
8. The system must be checked for visual damages before commissioning. Any damage must be
repaired immediately.
9. The hydraulics must only be operated if in a flawless state.
10. All objects and other materials not required for the operation of the hydraulics must be removed
from the operating area.
11. Ensure that all safety devices have been installed and are fully operational. When the system
isin operation, safety devices must not be removed or put out of operation.
12. Ensure that only authorized personnel are in the operating area and that no person is
endangered by commissioning the hydraulics.
13. Works must only be done when the system is pressure less and electrical power has been
disconnected. When work is in progress, the system must be protected against accidental
activation.
14. There is a risk that hydraulic oil is discharged from the system at high pressure and high
temperature
15. Ensure that all components are at room temperature when working.
16. A hazardous operating area must have restricted access. Ensure that unauthorized personnel
cannot enter the area.
17. Sempell does not accept liability when regulations, instructions and warning indications have
not been observed.
Operating the actuators, routine maintenance, spare parts
Read all warnings before operation and/or maintenance of the hydraulic control system!
General
Any regulations for waste reduction, recycling
and disposal must be observed. It is not
allowed to make any changes to the system
without prior approval in writing.
In the event of fire, the system must be
switched off by the main switch.
In case of malfunctioning electronics, there is
a risk of electric shocks.

Operating the actuators
Hydraulic actuators can be operated by the
pressure of the connected unit or by a hand
pump (optional). The corresponding solenoid
valves must be electrically controlled.
Routine maintenance
Maintenance should be carried out at regular
intervals. Hereby the hydraulic oil should
be checked (oil test in the laboratory) and,
ifnecessary, replaced.
The hoses must be replaced as a whole if they
have been damaged or at the first signs of
leakage.
Spare parts
A hydraulic control system is identified by the
order number stamped on the identification
plate. This reference should be quoted when
making any after sales queries, spare parts or
repair enquiries/orders.
