I Photo may include optional equipment. 4 HL780-7A_new_en 12-03-2009 14:59 Pagina 5 Control Center The all-new, deluxe operating space was engineered with 3-D modelling to optimize your ultimate control centre. The wide, tinted and laminated front windshield has no framing cutting through to ensure excellent visibility. Adjustable steering column The Air Conditioning and Heating System The operator can easily control the temperature and air flow . The defroster on the front windshield and rear window makes it convenient for winter working usage. 40 FNR Switch on Joystick Control Lever A forward/neutral/reverse travel switch can be installed on top of it for operators convenience. [. . . ] For each gear change, the control unit performs a monitoring function to ensure that the specified shift curve is adhered to, and readjusts the shift pressure applied to the clutches accordingly. This result in smooth gearshifts under load without traction interrupts. It also prevents standstills, sudden load changes or torque peaks during operations such as steep hill driving with full load. In addition, there is the option for the driver to make manual gearshifts. 7 HL780-7A_new_en 21-08-2007 10:05 Pagina 8 Accessible and Serviceable New Generation, Innovative Solution in Earth Moving, the HL780-7A Accessible grease fittings Grease fittings are highlighted and available around the machine for fast access when doing your service checks. Simple air filter replacements The air cleaner is easily replaceable by turning the wing nut on the outer shell, counter-clockwise. Open pin access You can quicker remove or tighten your front attachment pin (chromated) with this open connector system. Remote type drain port It is now easier to change your engine oil, coolant and hydraulic oil with the remote drain port located near the rear axle of the machine. I Photo may include optional equipment. 8 HL780-7A_new_en 21-08-2007 10:05 Pagina 9 An ideal arrangement of components ensures quick and convenience maintenance. Highly accessible engine compartment assures fast and efficient repairs when necessary. Hydraulic tank The hydraulic tank is located behind the cab to facilitate accessibility to hydraulic hoses and pipes. Oil sight gauge A sight gauge is installed on the side of the hydraulic tank for convenient ground level check out. Transmission oil port The transmission oil change port is openly accessible. It comes with an anti-vandalism lock for machine protection. Central electric controllers & Fuse Box Electric controllers and a concentrated fuse box are centralized to improve serviceability. Cabin Air Fresh Filter The internal pressure is maintained slightly higher than the outside to exclude dust from entering in and reduce noise levels to the cabin. Coolant Sight Gauge A coolant sight gauge is installed on the top of the radiator for convenient checks of coolant level. Easy Access to All Engine Components Here you find the engine oil check, main and pre-filters (fuel, oil, coolant). The large engine-sidepanels permit easy and safe access for inspections. The filters can be screwed on and off for quick replacements. Up-to-date hydraulic remote cooling fan Minimum fuel consumption and low noise is realized by using a hydraulic cooling fan sensing coolant-, air intake-, transmission oil- and hydraulic oil temperature. Reversible cooling fan is installed. 9 HL780-7A_new_en 05-11-2007 16:56 Pagina 10 Specification Engine Maker/Model Type CUMMINS QSM11 4-cycle, turbocharged, charge air-cooled direct injection, electronic controlled diesel engine 250 kW (335 HP) / 2, 000 rpm 239 kW (320 HP) / 2, 000 rpm 272 kW (365 HP) / 1, 800 rpm 1, 710 Nm (1, 235 lbf. ft) / 1, 400 rpm 6 Bore x Stroke Displacement Compression ratio Air cleaner Alternator Battery Starting motor 125 mm (4. 9") x 147 mm (5. 8") 11 liter (660 cu in) 16. 3 : 1 Dry, dual elements 24V, 70 Amp 2 x 12V, 160 Ah. of cylinders * Net power output of standard engine as installed in this vehicle (per SAE J1349) complete with fan, air cleaner, alternator, water pump, lubricating oil pump and fuel pump.
