Operating and Safety Instructions

Hydraulics

without notice SEMSH-0065-EN-1310

Before mounting the hydraulics these instructions must

be fully read and understood.

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.

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 spring-

loaded hydraulic actuators, the springs

must be released.

Working on the hydraulic control system

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.

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

isin 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,

ifnecessary, 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.
