Tradition and InnovationThe new compact mini-excavator is the product of the competence and the technology that KOMATSU has been
acquiring for over the past eighty years. The project has been developed with a constant attention to the needs of
customers from all over the world; the result is a user-friendly machine, which offers top class performance.
WALK-AROUND
PC18MR-2 M I N I - E X C A V A T O R
PerformanceThe new short tail PC18MR-2 supplies optimal power
and digging speed in confi ned spaces: yards, road
work, wherever traditional machines cannot work.
Sturdiness and excellent stability ensure safety and
confi dence in any condition.
Komatsu CLSSThe CLSS (Closed Load Sensing System)
hydraulic circuit guarantees power, speed
and perfect control to all movements,
including the combined ones. The main
feature of this system is the connec-
tion between the variable displacement
pump and the closed-centre circuit with
load sensing, which allows operators to
perform all movements with maximum ef-
fi ciency, regardless of the load or the rpm.
These characteristics are highlighted by
the hydraulic servo-controls, which are
by far the easiest to use and require mini-
mum efforts to perform extremely precise
manoeuvres.
ComfortDespite its compact size, the PC18MR-2 offers a
comfort which has no equals. Thanks to the wide
operator space, excellent accessibility to the seat
both for canopy and cab version, large fl oor free from
obstacles, adjustable seat and ergonomic position of
all the controls, the comfort of this new miniexcavator
can be compared to the one of higher category.
VersatilityMany available confi gurations allow the operator to
choose the right machine for the specifi c job: short or
long arm, canopy or cab, rubber or steel shoes, extra
counterweight.

Moreover, the 1 / 2 way auxiliary hydraulic circuit con-
sents to use multiple working tools, like the hammer,
the clamshell bucket, the auger, etc.
ORFS hydraulic face seal connectors and DT electric
connectors improve the reliability of the machine and
make repairs easier and faster.
Special technical solutions have allowed to extend up
to 500 hours the intervals for most ordinary mainte-
nance operations, such as pin greasing or engine oil
replacement.
Also, to avoid possible leakage, all tanks are equipped
with a draining hose: this confi rms once again the
attention KOMATSU pays to the environment.
MaintenanceAll periodic inspection points are easily accessible
through the bonnets.
In addition, extra-ordinary maintenance can be per-
formed by simply tilting the canopy upwards: under
the fl oor, the operator can fi nd all major hydraulic
components, like the main valve or the swing motor.

Designed with the utmost attention to detail, the operator’s environment ensures that comfort, accessibility and
visibility are not compromised. The two pole canopy, or the cab with the wide sliding door, allows easy access
to and from the machine. Once seated the spacious and obstacle free fl oor grants even the tallest operator room
to move his legs. The operator’s environment is further complemented by the adjustable seat and the ergonomic
PPC controls. Two speed tracking is operated by a switch located on the dashboard where it is possible to moni-
tor all the machine functions.

OPERATOR'S ENVIRONMENT

EngineThe KOMATSU engine supplies the required power, keeping the fuel
consumption very low. By taking advantage of state of the art technolo-
gies, it ensures minimum levels of noise and emissions (STAGE 2).
Automatic Shift DownOnce turned on, this device automatically adjusts the hydraulic travel
motor to the working conditions: maximum displacement for faster
movements, minimum displacement for top drawbar pull. This process
doesn’t require operator’s support.
Attachment LineThe 1 / 2 way auxiliary hydraulic circuit allows the use of several tools for
different purposes: hammer, clamshell bucket, and so on. The switching
between the two options is realised simply by means of a cock, which is
located on the side of the machine and right behind a little bonnet.
Variable UndercarriageFor the applications requiring maximum versatility in terms of size and
stability, the PC18MR-2 is equipped with standard hydraulic extension
of the undercarriage, which can be easily obtained by operating a push
button and the blade control lever from the driver’s seat. This device
allows to shift from the maximum stability confi guration, for working, to
the minimum width, less than one meter, to drive through restricted pas-
sages or doors.
Reliability and OperabilityParticular technical solution contribute to increase the sturdiness and
the operability of the machine. Among these, we can highlight the cast
swing support, that confers extreme rigidity to the structure, and the
boom, that lodges the hydraulic hoses, protecting them from possible
damages, guaranteeing the best visibility over the digging area.
