[. . . ] Be sure the hoses are maintained as non-conductive. The hoses should be regularly tested for electric current leakage in accordance with your safety department instructions. A hydraulic leak or burst may cause oil injection into the body or cause other severe personal injury. Do not exceed specified oil flow or pressure for the tool you are using. [. . . ] excess pressure may cause a leak or burst. Do not feel for leak with your hands, contact with a leak may result in personal injury due to the high pressure in the hydraulic system. Make sure the hydraulic hoses are properly connected to the tool and locking rings activated before pressurizing system. System pressure hose must always be connected to tool in-port. System return hose must always be conncted to tool outport. Reversing connections may cause reverse tool operations which can result in personal injury. do not connect closed-center tools to open-center hydraulic system. This may cause extreme system heat and/or severe personal injury. Keep the hydraulic couplings free of dirt. Check that the electrical cable to the hydraulic unit is not damaged or can be damaged during work. Onlookers within the working area can be injured. After the job is done If there is a risk for freezing temperatures, drain the water from the radiator. Even if the tool does not require water, cooling water shall still flow through the radiator and thereafter to the nearest drain. The power unit is designed as a cart offering the possibility to hang the hydraulic hoses for easy movement between sites. When transporting between sites, the power unit is stored horizontally with the distribution box upwards. The weight of the hydraulic unit is 93 kg. Tightening torque During repair and maintenance that requires dismantling with subsequent reassembly and tightening of bolts the following tightening torque should be used: M6: 10 Nm M8: 25 Nm M10: 50 Nm The hydraulic oil should be changed as needed or once each year. The oil draining plug is at the bottom of the oil tank. Collect the used oil in a sufficiently large vessel. Hydraulic oil is filled through the filter at the front of the tank. Position the unit with the filter housing turned upwards. Remove the filter housing cover by removing the three screws. [. . . ] Fill with new hydraulic oil (about 10 litres) through the filter cartridge. If the oil filter is also changed, fill with 12 litres of new hydraulic oil. GB Hydraulic oil filter The filter shall be changed twice yearly. Position the unit with the filter housing turned upwards. [. . . ]
