ward, making inspection of the engine
and hydraulic systems easy.
Reduced Maintenance Costs
Replacement intervals of engine oil,
engine oil filter, and hydraulic oil filter
are extended to 500 hours, and
replacement interval of hydraulic oil is
extended to 5000 hours.

The boom foot hoses are arranged
inside to reduce hose bend during
operation, extending hose life and
improving operator safety.
Machine Availability Is Increased
by Vehicle Health Monitoring
System (VHMS) (Optional)
Vehicle Health Monitoring System
(VHMS) collects and stores operation
data of machine and major components
in real time. Collected data are not only
various kinds of machine data such as
engine oil temperature, engine exhaust
temperature etc, but also includes oper-
ating condition data such as fuel con-
sumption, engine load factor etc.
These data can be utilized by download-
ing personal computer to effectively
diagnosis machine health conditions.
Moreover, combined with EMMS func-
tion which displays error code, machine
and maintenance information on color
graphics screen (patent pending), VHMS
reduces maintenance time and increas-
es machine availability.
Orbit communication function
(Orbcomm) available as an upgraded
feature of VHMS enables remote moni-
toring of the machine condition.

Increased Reliability

The PC1250-7 incorporates many improvements in strength and reliability.
Frame structure. Plate thickness of the revolving frame and center frame
is increased and stiffener plates are added to improve durability.
The boom and arm have increased cross section and plate thickness,
as well as continuous both-side groove welding, improving digging
and side contact strength.
All of the major machine components such as engine, hydraulic pumps,
hydraulic motors, control valves, etc., are exclusively designed and
manufactured by Komatsu.
In-line filtration
The undercarriage is strengthened
to provide excellent reliability and
durability when working on rocky
ground or blasted rock.
Metal guard rings protect all the
hydraulic cylinders and improve
reliability.
Heat-resistant wiring is utilized not
only for the electric circuit of the
engine, but also for other whole
units.
