A trench roller that dies mid-lift rarely fails politely, and this Wacker RT560, RT820 repair manual PDF puts 130 pages of factory service data between you and the tow strap. Hydraulic flow diagrams trace oil from the drive pump through the control valve block, so a sluggish exciter or a dead travel circuit stops being a mystery. Wiring diagrams for the CombiControl transmitter and infrared receiving eye cover the remote system that strands more of these machines than the engine ever does. Check the sealed battery against its rated 800 cold cranking amps before you condemn a starter, then set drum mounting screws to 155 ft.lbs. (210 Nm) on reassembly. A rebuild that stalls over one missing torque figure is a rebuild half done. Pay for this bookmarked, keyword-searchable PDF once and it belongs to you for the life of the machine.
