GB To avoid functional disturbances, we recommend that you read these instructions thoroughly before using the product. Technical description (Fig. 1) Working pressure: 2 MPa (2 bar, 29 psi) 7 MPa (7 bar, 115 psi) Required air pressure: Fig. 2 Capacity: Fig. 3 Total oil capacity: 15 cm 3 (64 in 3 ) Effective oil capacity: 1 cm 3 (61 in 3 ) Weight inc. oil: 7,5 kg (16.5 lbs) Because the pump has a rubber bladder fitted inside the tank it can be used either horizontally or vertically. and maintain the achieved hydraulic pressure when the pedal is released in the neutral position. Releasing To release the cylinder or tool, press the release pedal (Fig. 4, item C). Hold the pedal down until the cylinder has moved back to the desired position. NOTE! Do not overfill when loading rams/tools. Doing so can cause the oil reservoir to burst. Maintenance When necessary lubricate moving parts such as the pneumatic piston and valve with high-grade grease. Safety feature The pump is equipped with a safety valve that regulates the output pressure. The safety valve is set to the maximum working pressure at the factory. Installation Connecting compressed air The pump requires a compressed air pressure of at least,6 MPa (6 bar, 87 psi) to develop hydraulic pressures of 7 MPa (7 bar, 115 psi). Make sure that the air pressure does not exceed 1 MPa (1 bar, 145 psi) as this could damage the pump. To ensure efficient operation and long life use clean compressed air with a water trap and oil mist lubrication. Connect the compressed air line using a G 1/4 coupling, as shown in Fig. 1, item A. Bleeding the hydraulic system When hoses or tools are connected to the pump they can introduce air into the hydraulic system, which could lead to operating problems. Bleed the system by running the tool or cylinder through 3 4 cycles (by pumping out until fully extended, then releasing) with no load. Make sure that the tool or cylinder is kept lower than the pump to allow the air to flow back into the oil reservoir of the pump. Then hold the pump with the oil reservoir at the top while pressing the pump pedal and release pedal at the same time for around 15 seconds. It may be necessary to top up the oil depending on the volume of air in the connected hoses or tool, see Filling with oil. Service Filling with oil Check the oil level before use. Always measure the oil level with the cylinder or tool in the lowest or retracted position. To ensure efficient operation use an hydraulic oil that conforms to ISO VG 1. - Stand the pump up with the pneumatic motor lowermost (Fig. 5). - Unscrew the oil filler plug (Fig. 5, item A). - Fill the oil reservoir through the filler hole until the oil reservoir is completely full (1,5 cm 3, 64 in 3 ). - Screw the oil filler plug back into place. For safety reasons, service and repair of this product must be done by a knowledgeable person. Upon the slightest doubt, contact your distributor for information about the nearest authorized workshop. System design When you plan a hydraulic system always choose products that are suitable for the chosen application. Check product limitations with regard to pressure range, lifting capacity and connection options. The maximum working pressure of the system must not exceed the maximum working pressure of any product that is included in the system. Make sure that all hydraulic hoses, couplings, etc., are connected to the correct connection port (pressure or return connection) on the pump, cylinder, valve or other hydraulic component. Starting Hydraulic pressure 2 MPa (2 bar, 29 psi) To extend the cylinder or tool, press the pump pedal (Fig. 4, item A). The pump will stop and maintain the achieved hydraulic pressure when the pedal is released in the neutral position. Hydraulic pressure 7 MPa (7 bar, 115 psi) To extend the cylinder or tool, press the pump pedal and the pressure regulating valve simultaneously (Fig. 4, item B). The pump will stop 2
