This JCB Service Manual covers the 505-19, 505-22, 506-36, 508-40, 510-40, and 506B telehandlers of the 500 Series, publication number 9803/3600U. Across 701 pages it documents every major system on these machines, from the hydraulics and the PlaceAce and Servo control systems to the engine, transmission, axles, brakes, hydraulic steering, and electrics.
With it you can diagnose a hydraulic fault, set the main relief valve pressures, shim the boom, service the Syncro Shuttle or Powershift transmission, bleed the brakes, and trace wiring through the electrical section. Technical data tables give torque figures, fluid capacities, and pressure settings for each model variant, so you can match the procedure to your exact serial number.
It is the factory workshop reference for owners and mechanics keeping these Loadall telehandlers running.
