Read the operating instruction

Wear protective goggles

Servo, hydraulic pump and accessories are part of the hydraulic system called expander. Expander can be used in the work of the assembly works and tinsmithing to perform tasks, which are requiring the application of considerable static forces. The expander may not be used as hydraulic support, which is set on a permanent basis. The device has been designed only for use in private households and may not be used professionally i.e. in factories and for commercial tasks. Correct, reliable, and safe operation of the device is dependent on its proper use, therefore:

Prior to working with the tool, you should read all the instruction and keep it around.

For any damages or injuries caused by the tool misuse, resulting from failure to comply with its designation, noncompliance with safety regulations and recommendations included in this manual, the supplier does not accept any liability. The tool misuse causes also the loss of user's rights to the guarantee and warranty.

SAFETY RECOMMENDATIONS

The hydraulic system is working under a heavy load. When operating it you should observe basic safety rules.

Before beginning your work, read the manual and keep it around.

Never exceed the maximum load of hydraulic system.

It is forbidden to use the device to move people or animals.

Do not use the hydraulic expander as a lift.

The hydraulic system is designed only to move, and use it for other purposes is prohibited.

Do not stretch the expander beyond its rated range, because it is possible to squeeze its piston out of the servo housing. Do not wear loose clothing or jewelry during work. Pin up long hair.

Apply the personal protection equipment.

The hydraulic pump must be placed on a level, flat, hard, and stable surface.

Surface, which is supporting the expander, should be stable and resilient.

It is absolutely prohibited to adjust safety valve.

EN

Keep the hydraulic system components away from sources of heat and fire, 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 effort.

Keep the hydraulic system components away from sources of heat and fire, 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 influence 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 filled 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 fill the pump tank completely. The oil level must be at least 1 cm below the oil inlet. After oil addition screw the filler plug. The device has been factory-filled 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 hydraulic oil.

FAILURE DETECTION

Failure Possible cause Solution
Pump is not running.	Dirt in the valve seals	Pass the device to a specialized service
	Worn seals
The pump does not produce a pressure	Aeration of the hydraulic system Carry out the procedure of deaeration The pump is not stable under load
The pump does not lower completely
The pump does not produce a pressure	Inappropriate oil level in the pump tank	Carry out the procedure for checking the oil level.
