Kobelco SK300LC-10 / SK350LC-10: circuits and chassis
SK300LC attachment flow and regeneration
Independent Travel on the SK300LC-10 assigns a main pump to travel and another to the attachment during combined movement. Boom-to-arm regeneration uses oil displaced as the boom lowers to help extend the arm. Neither function means every hydraulic outlet receives the sum of the main-pump ratings.
The monitor's attachment switch selects the circuit and flow appropriate to the tool. Check the selected breaker or nibbler setting when evaluating an equipped machine.
Kobelco separates normal digging force from Power Boost and separates SAE from ISO measurements. The arm length matters too: the long arm trades working force for reach. Its bucket-selection grid also restricts bucket size by material density.
Buying the largest listed bucket without checking that grid overlooks the purpose of those limits. The stated tank oil level is another distinct quantity: it excludes oil held in cylinders, lines and the rest of the hydraulic system.

The North American SK350LC-10 drawing offers short, standard and long arms on its common boom. Its equipped-weight table uses the standard arm and a stated bucket, then changes shoe width. That conventional undercarriage must be distinguished from a High & Wide machine.
Wider track gauge and extra clearance describe a different arrangement, not an unexplained disagreement between identical excavators.
Inside the SK350LC cab, the service display can retain intermittent electrical faults and show maintenance information. Its manual regeneration switch addresses the particulate filter; the separate DEF fill supplies the SCR system. Those are different parts of exhaust treatment.
The brochure also shows separate cabin filters for recirculated and outside air, removable without tools. For cooling-system inspection, the left-side access exposes the radiator group while engine-oil and fuel-filter service is identified on the right. A clean cab filter does not establish that either engine cooling or exhaust treatment is healthy.
Source: Kobelco SK350LC-10 North American brochure, maintenance and dimensional schedules.The High & Wide schedule identifies enlarged upper rollers, reinforced guide frames and double-grouser shoes for rough forestry ground. Its ground-clearance dimension excludes the shoe lug. Compare that dimension on the same basis before planning passage over a stump.
