Part of the New Holland Repair Manuals.
All 815 pages of this New Holland LM5.25, LM6.28 Service Manual PDF (OEM #47712952B) cover one machine family: the LM telescopic handlers, from the engine and DPF exhaust treatment down to the telescopic arm hydraulics. You get wiring diagrams with harness and connector layouts, hydraulic schematics for the variable displacement pump and main control valve, exploded views, error code references, and a torque table section right up front. Step-by-step procedures walk you through the powered front axle, hydrostatic transmission, brakes, steering, and cab air conditioning. Set joystick pilot pressure between 25 and 28 bar, and confirm main valve relief at 230 bar (3335 psi) before you chase a weak boom. No more bleeding circuits on a hunch. Bookmarked with a full text layer; jump to any section or search any spec straight from the phone in your shop.
