Parts catalog, shop manual or operation manual?
Choose a document by the job you need to do.
Parts catalog
Use exploded diagrams, reference labels, quantities and part numbers to identify components. A diagram alone does not give the repair procedure, tightening torque or safe disassembly sequence.
Shop or repair manual
Use the correct workshop edition for diagnostic and repair procedures. Confirm the covered machine or engine, revision, serial range and language. Never substitute a similarly named model.
Operation and maintenance manual
Use the operator material for machine controls, operating precautions and scheduled maintenance information for that edition. It is not a complete parts catalog or workshop manual.
Online catalog or PDF?
Online catalog access supports searching and navigating assemblies. A PDF is a separate document purchase for the specified edition. A Komatsu subscription does not automatically include every PDF; CAT online access is currently free.
