Keep the hydraulic system components away from sources of heat and fi re, as this may cause damage to the device or
deterioration in its performance.
Do not place any heavy objects on the hose nor allow to bent it. Do not allow the hose to come in contact with sharp or hot objects.
When setting up the hydraulic system you should take into account the space required for the hose, to avoid damage to the hose
or coplings.
Before starting your operation, make sure that no element of the hydraulic system is damaged in any way. If any of the elements
needs a repair, it should be passed to an authorized repairer for this purpose.
After unplugging of the cables always put on plugs, to protect the hydraulic system from dust and other contaminants. If the load
is not centrally located, pump carefully. If it is necessary to use a very large force for pumping, you should stop your work and set
up the device in such a way, that the load is placed more centrally. This will reduce the pumping eff ort.
Keep the hydraulic system components away from sources of heat and fi re, as this may cause damage to the device or
deterioration in its performance.
Never leave assembled system without supervision of the person, who is authorized to its operation. Children and people, who
are untrained to operate the hydraulic system, are not allowed to be present near the place of operation or storage of the hydraulic
system components.
Observe the general safety rules during your work.
Be prescient, do not work when you are tired or under the infl uence of drugs.
USER'S MANUAL
Installation and use of the hydraulic system
Connect the pump hose with the servo connector by screwing the connector nut of the thread. Make sure that the nut is properly
tightened (II).
Close the drain valve by turning it in clockwise (III).
Produce pressure in the pump by moving its lever up and down. After several moves, the servo will start to work.
To eliminate the pressure in the pump, turn the valve counterclockwise.
At time of opening of the drain valve, the servo will automatically return to its rest position.
Do not disassemble the hydraulic system, which is under pressure.
The pump can be used in any position, both vertically and horizontally. When the pump is in vertical position, the ending with hose
must always be directed downwards (IV).
Oil addition (V)
The pump is fi lled with oil and ready for operation. If you notice a performance drop of the pump, you should check the oil level;
and add oil when necessary. Disconnect the pump from the hydraulic system, set in a horizontal position, unscrew the oil plug
and add oil. You should not fi ll the pump tank completely. The oil level must be at least 1 cm below the oil inlet. After oil addition
screw the fi ller plug. The device has been factory-fi lled with hydraulic oil. Use only oil of the proper type. It is recommended to use
hydraulic oil with the symbol ISO VG15.
Deaeration of the pump
To deaerate the hydraulic system of pump, set pump in vertical position, with its hose directed downwards. Open the drain valve.
Unscrew the oil inlet plug. Do a few full movements of the pump lever. Screw the oil inlet plug.
MAINTENANCE
Elements of the hydraulic system must be protected against moisture. You should not expose them for adverse weather conditions,
especially for precipitation. System components must be kept clean and free of any oils or greases. All moving parts should be
oiled. You should periodically check the condition of the elements for presence of rust.
Before each use, check the technical condition of elements of hydraulic system. If you notice any damage, the operation of
hydraulic system is strictly prohibited. In this case, you should pass the device to an authorised service center.
Do not adjust the safety valves, because they have been adjusted at the factory to ensure the nominal performance and maximum
security of device.
When the hydraulic system is not used, its pump should be kept with the opened drain valve. After a period of heavy use we
recommend that you make an oil change, which will allow to prolong the service life of the device. In order to change the oil, you
should open the drain valve, then open the vent valve and discard old oil. Make sure that any dirt would not get inside the system.
Fill out with the appropriate type of hydraulic oil up to the level as it is described under "Checking the oil level" paragraph.
The expander should be stored in its original package. After completing the work, the components should be carefully cleaned
with a clean cotton cloth. Special attention should be paid to carefully secure the hydraulic system connectors, by setting up
protective screens.
It is recommended that you store the set at temperatures above 0
C, which will ensure the appropriate parameters for the
O
hydraulic oil.
