Komatsu PC01-1 to PC03-2F specifications

PC01 access width and PC03 attachment circuits

The PC01-1 uses a gasoline engine and a very narrow tracked chassis; the later PC03-2 documentation describes a diesel machine with selectable attachment piping. Access through a gap, servicing the engine and running an auger are consequently different selection questions. Match the brochure edition and installed controls before choosing between these records.

PC01 boom swing is separate from turning the whole upper structure

The Japanese PC01-1 brochure describes both full upper rotation and boom swing. That lets a reader distinguish moving the boom sideways from swinging the entire machine. Its blade also serves backfilling and leveling; the optional carry bucket attaches to that blade for moving material.

Its single travel lever controls travel and steering, while the seat doubles as an opening service cover. Inspect access beneath the seat before describing maintenance space as an engine compartment behind a conventional excavator cab.

The brochure separates a long-arm option from the standard arm. Keep the working-range figures with the arm they describe; the longer attachment cannot inherit the standard configuration's reach and handling assumptions unchanged.

The PC01 capacity correction concerns the bucket, not engine displacement

Komatsu's export brochure gives bucket capacity in cubic metres and cubic feet. The old cubic-yard entry was a different quantity. The corrected record retains the documented bucket volume and machine mass; the earlier entries remain labelled below.

The regional manufacturer list independently identifies the same small bucket and mass.

The PC03 name needs a serial range as well as an engine designation

The 2002 US PC03-2 sheet names a 2D68E diesel engine. The older comparison entry names a 1D84, so the later sheet must not silently replace that record. Photograph the engine plate before selecting engine-service information.

SEAM040600 covers PC03-2 serial numbers 21587 and up. Its attachment section distinguishes two-way piping for an auger or crusher from one-way flow for a breaker. A pedal that supplies pressure in only one direction may reflect the selected circuit mode; check the installation against that manual before assuming a failed valve.

Breaker use also changes its hydraulic maintenance schedule because the manual describes faster oil deterioration. Request the breaker-use service history separately from ordinary bucket-digging maintenance records. The normal schedule alone does not establish that the attachment duty was covered.
