Overview
The Kubota KX36-3, KX41-3S and KX41-3V Excavator Workshop Service Manual provides technical information covering the construction, operation and component identification of these Kubota compact excavators. The indexed mechanism documentation addresses machine specifications, front attachments, swivel and track assemblies, electronic control systems, hydraulic components and engine operating characteristics. Model-specific information helps distinguish the equipment arrangements and technical features of the covered excavators.
The workshop reference includes the Kubota Intelligent Control System (ICS), electronic service modes, stored failure records, controller self-diagnosis and electrical circuit diagrams. Hydraulic coverage addresses main pump performance, control valves, pilot valves, travel and swivel motors, rotary joints, unload valves and service-port performance. Regional references distinguish European, North American, Oceania and KTC/KCL/KTA configurations, while the engine section provides specifications, performance curves and coil commander inspection and troubleshooting information.
Important Information: The indexed document covers mechanism information for the KX36-3, KX41-3S and KX41-3V family. Some electrical and hydraulic references are specific to the KX41-3V or particular regional versions. Any additional workshop documents should be checked individually for their language, model coverage and servicing procedures.

Intelligent Control System and Regional Hydraulic Differences
The electrical documentation describes the Kubota Intelligent Control System used in the KX41-3 family, including operating modes, service menus, electronic failure records and controller self-diagnosis. The indexed references include a specific service mode for a KX41-3 configuration without Auto Idle, anti-theft or S/P functions. Consult the appropriate wiring diagram and controller configuration when identifying electrical components or interpreting diagnostic information.
The Hydraulic System chapter distinguishes European and export configurations through separate circuit diagrams, control valves and travel motor references. It identifies the main pump, pilot and unload valves, swivel motor, rotary joint and KX41-3V selector valve, together with service-port performance samples for the KX36-3 GL and KX41-3V GL. These specifications and circuit references should be matched to the excavator’s regional version before applying them to hydraulic inspection or diagnosis.
