Please pay attention to all current safety and accident prevention instructions during system transport. 2.3 Disposal Note! Observe all disposal regulations when changing the lubricant! Collect cloths that are contaminated with lubricant and dispose of them properly. The disposal of the hydraulic pump itself must be executed properly according to all applicable national laws and regulations. 7
INDECO SECTION 3. - General Description Overview Note! The system is used to lubricate hydraulic hammers or other construction machinery demolition attachments. Due to its compact design, it can be mounted directly to the attachment. Powered by a hydraulic motor (item 9, fig. ), the system delivers a continuous supply of lubricant. The delivery rate is adjustable via a throttle (item 8, fig. ). In the event of a hydraulic system failure, a grease nipple is integrated for manual greasing (item 5, fig. ). Transparent plastic cartridges (item 7, fig. ) serve as a storage reservoir. The grease level is checked optically by the position of the visible follower piston. For supply, the grease pump is connected with a bypass line to the supply and return lines of the carrier hydraulic system. This can done via the hose lines or by direct flange connection. Functionality can be checked via the visible eccentric shaft (item 2, fig. ). At the time of delivery, the securing bolts, inlet screw couplings and plug screws are supplied with the pump in loose condition, together with the appropriate seals. Depending on the application, minor assembly work may be required before commissioning. - In the case of the hose connection model, the enclosed screw couplings must be mounted. As a result the grease pump's supply and return lines must be connected to the carrier's hydraulic system via a bypass line. G/4" screw couplings are required for the connection of the oil and lubricant lines. - In the case of the flange connection model, the G/4" threads must be closed by the enclosed plug screws and packing rings. The enclosed 0-rings are used to seal the flange connections. Figure 8

INDECO SECTION 3.3 - Pump Assembly Pump Assembly The pump can be positioned with the cartridge in a horizontally or vertically suspended position. If the cartridge is in a vertical position, please make sure that dirt or other contaminants do not fall into the intake area below the cartridge. Attention! The location and type of pump installation must be coordinated with the manufacturer of the carrier unit. Before commissioning the unit, please make sure to fill the lubricant lines via the grease nipple (item 5, fig. )! 3.3.. Connecting the Pump Attention! First close the bore holes for the flange connection model F-F3 (fig. 3) on the back of the pump by means of the supplied hex socket screw M4x, using the Cu seals 4x8x. Note! The O-rings 9x2.5, plug screws G/4 and packing rings 3x8x.5 are not required for this application. The lubricant is connected to the S connection (fig.3) in the standard version. Connect a bypass line to the hydraulic system of the carrier unit for supply of the grease pump - the pressure line at S3 (fig. 3). Two hex bolts M4x4 with lock washers are included in the scope of supply for fastening the pump. These must be tightened using a torque qrench (0 Nm). 3.3.2 Flange Connection Model Drill the connection and the attachment bores according to the drilling pattern in the lower right of Fig. 3. Attention! First close the bore holes for the hose connection model S-S3 on the pump by means of the plug screws G/4 enclosed, using the Cu seals 3x8x.5. Note! Check whether the connecting bore holes are in the required area according to the drill pattern in fig. 3. Insert the O-rings 9x2.5 supplied in the bore holes F-F3, making sure the seating surfaces are extremely clean. Two hex bolts M4x0 with lock washers are included for fastening the pump. These must be tightened using a torque wrench (0 Nm). 0
INDECO SECTION 3.4 - Installation Dimensions
INDECO SECTION 4. - Functional Description Functional Description The hydraulic pump is connected to the hydraulic system of the carrier unit via the pressure pipe P fig. 5). The hydraulic oil is routed through a filter with cover (item 7, fig. 5), via the setting throttle (item 8, fig. 8) and to the hydro motor (item 6, fig. 5), which ensures a continuous drive. The hydraulic oil is returned to the hydraulic circuit via the return line R (fig. 5). To enable regulation of the hydraulic motor s speed and thus the stroke rate of the delivery plunger or the delivery flow, the oil throughput can be adjusted via a throttle (item 8, fig. 5). The hydraulic motor drives a worm shaft, (item 5, fig. 5), which transmits the revolutions to the eccentric unit (item 4, fig. 5). Eccentricity gives rise to the suction and delivery stroke of the delivery plunger of the pumping element (item 3, fig. 5). An integrated non-return valve (item 2, fig. 5) prevents the pumping medium from being sucked back. Via the pressure channel D, the lubricant is supplied to the various outlets which are either open or closed, depending on their installation location or position. Lubricant cartridges serve as supply tanks for the lubricant (item, fig. 5). 2
INDECO SECTION 4.2 - Start Up Procedures 4.2. Changing the Cartridge After initializing the equipment, fill the lubricant line using the lubrication nipple at the front of the pump (see item 4, fig. 9). Next, slightly grease the O-rings in the adapter (item 2, fig. 0) and then install your first cartridge. To accelerate priming, first remove the cap from the cartridge opening; then, using the cartridge follower piston (item 3, fig. 5), press out the grease by 5 mm to 0 mm (fig. ). Following priming, insert the cartridge in the cartridge holder (item, fig. 9) by pressing it slightly and fastening it by hand. Attention! When replacing the cartridge, please make sure that no contamination enters the intake area of the cartridge! 4.2.2 Adjusting the Delivery Quantity Please note that the system must be depressurized before adjustment! Before adjustment, you must remove the plug screw (item 2, fg. 3). Afterwards, you can release the throttle (item 4, fig. 3) using a slotted screwdriver. By unscrewing the throttle, you can increase the flow rate, thus enhancing the delivery rate (fig. 4). You can check for proper working condition via the visible eccentric shaft (item 5, fig. 2). Determining the number of revolutions of the eccentric shaft or the number of strokes of the delivery plunger enables calculation of precise delivery rates. Before recommissioning the pump, reposition the plug screw with the Cu sealing ring (item2 and 3. fig. 3). 3
INDECO SECTION 4.2 - Start Up Procedures The following diagram shows the guide values for adjustment of the throttle. Before adjusting, screw the throttle clockwide (inwards) to its stop. By unscrewing the throttel counter-clockwise, you can adjust the required delivery rate. Figure 4 Adjustment of the revolutions of the eccentric (pump delivery rate) is made via an adjusting throttle, the oil flow rate requiring adjustment on each pump individually. The values of the throttle rotations in the table above are to assist adjustment. If the required delivery rate is not known, you can assume a range between 0.5 and.0 cm3/min. for most hydraulic hammers. 4.2.3 Changing the Filter and Orifice Ventilate the whole lubrication system after the first operation and after each lubricant exchange Ventilation is done at pressure less operation and open outlets of the system Operate the pump until lubricant comes out of the pressure connection without air inclusions 4
INDECO SECTION 4.3 - Maintenance & Repair Maintenance STOP the voltage feed before initiating any maintenance or repair operations. Maintenance and repair work should only be done at standstill of the central lubrication pump and in pressureless conditions. lways weat heat-resistance gloves and protective goggles as the surface may be hot! Soiled surfaces have to be cleaned before work and you should wear protective clothing, if necessary. Always make sure that you protect the device against unintentional reactivation during maintenance and repair operations. 4.3. General Maintenance Retighten all fittings six weeks after start-up Check all components for leakage and damages every four weeks If leakages are not repaired, lubricant can come out with high pressure. Remove possible leakages of lubricant immediately. 4.3.2 Refilling with Lubricant Always make sure that the environment is as clean as possible when refilling! Attention! Check the level regularly and refill if necessary (see the START-UP Section of this manual) Only use lubricants that are suitable for the lubricating machine and meet your specific application requirements If ordering lubricant from other manufacturers, make sure the quality is similar to that previously used and drain and clean the reservoir completely as a precaution. 4.3.3 Changing the Filter and Orifice To replace the filter and orifice, first remove the plug screw (item, fig. 5 and fig. 6) using a wrench (SW3). Then, release the thrust piece (item 3,fig. 6), the O-ring (item 4, fig. 6) and the strainer (item 5, fig. 6). Then unscrew the orifice (item 6, fig. 6) using a slotted screwdriver. Attention! When reinstalling, make sure that the sealing edge of the orifice is not damaged. After having screw-fastened the orifice again, you can reinstert the strainer, the O-ring and the thrust piece, fastening them with the plug screw and the Cu seal (item 2, fig. 6). Fig. 5 5
INDECO SECTION 4.3 - Maintenance & Repair 4.3.4 Changing the Pumping Element Before removing the pumping element, make sure that the system is depressurized. To remove the pumping element, first take out the lock screw on the front of the pump housing (item, fig. 7 and fig. 8) using the 8 mm key. Then pull out the pumping element (item 2, fig. 8) utilizing the pulling device (fig. 9) supplied with the system. To accomplish this, screw the pulling devng device into the thread (item 3, fig. 8) on the front of the pumping element. Pull the pump element from the housing bore. Make sure that all components (items 4, 5 and 6, fig. 8) are moved. and 6, fig. 8) are moved. Attention! When installing the new pumping element, please exercise care to make sure that no dirt gets into the pump. The intake bore (item 7, fig. 8) must be directly below the lubricant bore of the grease cartridge (item 8, fig. 8). Clamp the pump element again with the closure screw (item, fig. 8). Slightly grease the O-ring on the closure screw (item 9, fig. 8). Attention! When using copper paste, please note that you must replace the pumping element after approximately 000 service hours due to the solids content. 6
