If oils are used that do not comply with the above mentioned quality requirements can possibly invalidate our guarantee obligation. We draw your attention particularly to the fact that each oil manufacturer or oil supplier is responsible for the quality of its product itself. VIDCOSITY OPERATING CONDITIONS CLASS ----------------------------------------------------------- 22 For very cold conditions or for extremely long lines. 32 For winter conditions 46 For summer conditions or closed rooms 68 For tropical conditions or for rooms with high temps 100 For excessively high temperatures NOTE: The code number of the viscosity classes (VG) refers to the midpoint viscosity in mm squared at T oil=40 degrees C NOTES REGARDING THE HYDRAULIC SYSTEM CAUTION! -Auxiliary components or equipment may only be connected to the hydraulic system and the already assembled components using the provided interfaces. Mechanical treatment (Drilling, milling, etc.)and thermal processing (welding, etc.) are not allowed. Especially the container for the compressed fluid may not be mechanically treated in no way. -There will be the risk of leakage and pollution. -Hoses may not contact hot components. -Pipe lines must be laid free from tension and sufficiently fixed with pipe clips. -Hose lines have to be secured against whipping in case people can be within the dangerous area. DEPRESSURIZING OF THE HYDRAULIC SYSTEM CAUTION! Possible dangerous situation! ---Risk of minor moderate injuries if not obeyed. CAUTION! Possible dangerous situation! ---There will be a risk of material damage if not obeyed. -Turn the machine off. -Secure the machine against accidental switching on. -Attach a safety sign "Do not switch on! Men working on equipment" on the switch cabinet. -The machine may only be depressurized by specialist personnel. -Disconnect the hose connections from the cylinders. -Collect the hydraulic oil in a suitable container. -The hydraulic system is now depressurized. GENERAL CHECKS: -Check the oil level in the oil reservoir and refill oil through the filler neck if necessary. -Check the oil temperature (recommended 50 degrees C, maximum 70 degrees C in continuous operation.) -check the clogging indicator of the installed filters and replace filters if necessary. -Check for unusual noise. -Check the fastening of the pipelines in case of varying pressure.

CHECKING AND ADJUSTING OF THE TOTAL PRESSURE -Open the manometer cock (Item 7) -Return the slider using the input "Return slider manually" -Read off the pressure from the manometer (item 8) -Turn the machine off -Close the manometer cock (Item7) ---Set-up -Release the lock nut (Item 9) -Adjust the pressure control valve (Item 10) using an Allen key. -Turn clockwisely = increase of pressure -Turn counterclockwisely = decrease of pressure -Release the lock nut (Item 9) -Turn the machine off -Close the manometer cock (Item 7) The operating pressure preset at the factory may be changed only after consultation with the manufacturer.
FILLING OF THE HYDRAULIC CONTAINER Before filling the hydraulic fluid into the provided container, make sure that the fluid complies with the manufacturers specification. The hydraulic fluid has to be filled in via a filter and/or using a special filter unit. Before start filling, make sure that the clean filter elements of the required filter fineness are installed. Fill in the required quantity complying with the applicable instructions in the hydraulic diagram and make sure that it does not exceed the fill mark on the inspection glass or dipstick. After all consumers and lines have been filled with hydraulic liquid in the tank must be refilled. Proceed as follows: If necessary, clean the place of assembly and dispose of the oil- filled containers and oily materials so as not to pollute the environment. LUBRICATION INSTRUCTIONS BEARINGS -All maintenance and repair works are to be performed carefully and by thoroughly trained personnel. The operating temperature of the lubricant should not exceed a temp of 70 degrees C. -The bearings are lubricated on the grease nipple on the bearing (see list of grease nipples). -For the ball bearings, the roller bearing grease is replaced. To remove the used grease from the bearing, remove the bearing plug and pump the fresh grease very slowly into the running bearing while it rotates slowly or runs with low idle speed until color and consistency of the escaping grease are nearly equal to the one of the new grease. This change shows that no old grease is left in the bearing. - Only use grease types that are based on lithium. -Grease types listed in the next table only serve as recommendation for the maintenance of the bearings.
MAINTENANCE 15
Carefully perform all maintenance and repair works. MEASURES TO SPECIFIED BE TAKEN INTERVALS ------------------------------------- Monitor oil temp Continuously and noise Check oil level Every 3 months Oil change intervals 2000 hours/year CAUTION! OIL CHANGE - Generally fill the gear unit with the oil type used before. It is not allowed to mix several types, especially synthetic oils may not be mixed with mineral oils. DRAINING THE OIL -The oil must be discharged immediately after the gear unit has been set out of service as long as the oil is still warm. -Allow the oil to drop off for a sufficiently long time to remove oil sludge, fines and oil residues. If lucent bronze fines are in the oil, this is fully harmless. The below listed oil quantities are planned for the use without oil cooler. If an oil cooler is used, the oil quantity increases depending on the length of the hose line. The oils listed in the table below only serve as recom- mendation for the maintenance of the gear unit. If oils are used that do not comply with the mentioned quality requirements, this can possibly invalidate our guarantee obligation. We draw your attention par- ticularly to the fact that each oil manufacturer or oil supplier is responsible for the quality of its product itself. WARNING! Danger to the machine. -The machine may only be serviced by specialist personnel. -Wear suitable protective clothing when servicing the machine. WARNING!
