WORKING ENVIRONMENT
PC270-7 cab interior is spacious and provides a comfortable working
environment…
Large Comfortable Cab
Comfortable Cab
New PC270-7’s cab volume is increased by 14%, offering an
exceptionally comfortable operating environment. The large
cab enables full flat reclining of the seat back with headrest.
Pressurized Cab
With optional air conditioner, air filter and a higher internal air
pressure (6.0 mm Aq 0.2" Aq) prevent external dust from
entering the cab.
Low Noise Design
Noise level is remarkably reduced, not only engine noise but
also noise when swinging and hydraulic relief.
Low Vibration with Cab Damper Mounting
PC270-7 uses new, improved multi-layer viscous mount
system that incorporates longer stroke and the addition
of a spring. The new cab damper mounting combined
with strengthened left and right side decks aids vibration
reduction at operator seat.
Vibration at floor is reduced from 120 dB (VL) to 115 dB (VL).
dB (VL) is index for expressing size of vib ration.
Rubber
Spring
Silicon Oil
Automatic Air Conditioner (optional)
A 6,900 kcal air conditioner
is utilized. The bi-level
control function keeps the
operator's head and feet
cool and warm respectively.
This improved air flow
function keeps the inside of
the cab comfortable
throughout the year.

Multi-Position Controls
The multi-position, pressure proportional control
levers allow the operator to work in comfort
while maintaining precise control. A double-slide
mechanism allows the seat and controllers to move
together or independently, allowing the operator
to position the controllers for maximum
productivity and comfort.

Wide Visibility
The right side window pillar has
been removed and the rear
pillar reshaped to provide better
visibility. Blind spots have been
decreased by 34%.

prevents oil from spraying on
the engine if a hydraulic hose
should burst.

MAINTENANCE FEATURES
Easy Maintenance
Komatsu designed the PC270-7 to have easy service access.
We know by doing this, routine maintenance and servicing are
less likely to be skipped, which can mean a reduction in costly
downtime later on. Here are some of the many service features
found on the PC270-7.
● Easy Radiator Cleaning
Clearance between radiator
and oil cooler is increased
to facilitate radiator core
cleaning with an air nozzle.
Easy Radiator Cleaning
● Water Separator is standard
equipment, removing water
mixed in fuel and preventing
fuel system damage.
● Easy Access to Engine
Oil Filter and Fuel Drain
Valve. Engine oil filter and
Remote
Mounted

fuel drain valve are remotely
mounted to improve
accessibility.
● Easy Cab Filter Maintenance
Tool free removal of the internal and external cab filters.
Outer Air Filter
Removal and installation of air conditioner filter element,
without tools, facilitates cleaning.
Inner Air Filter
● Fuel Tank Capacity Increased
Fuel tank capacity is increased from 340 ltr 89.8 U.S. gal
to 400 ltr 105.7 U.S. gal to extend operating hours before
refueling. The fuel tank is treated for rust prevention and
improved corrosion resistance.
Water
Separator
Reducing Maintenance Costs
● Hydraulic Oil and Filter/Engine Oil and Filter
Replacement Interval Extended
The new high performance filters are used in the hydraulic
circuit and engine. Hydraulic oil filter, engine oil, and
engine oil filter element replacement intervals are significantly
extended to reduce maintenance costs.
All Work Equipment Lubrication Intervals are
500 Hours with SCSH Bushings (Excluding Bucket)
Newly developed SCSH bushings are used on bucket and arm
top bushing; end faces are injected with Tungsten Carbide.
All bushing lubrication intervals of work equipment are
extended from 100 hours to 500 hours (excluding the
bucket) reducing maintenance costs.
SCSH (Steel Copper Sinter
Hard Material) bushing is
based on ferroalloy powder
metallurgy (carbonized
treatment). It contains a special
lubricant in pores, and the hard
particles are diffused to
improve durability for wear
and scratching.
Tungsten Carbide Injected Bushing
Tungsten Carbide is injected into the end faces of the arm top
bushing to form a hard film, reducing wear of contacting
surfaces and fluttering of the bucket.
* Load is limited by hydraulic capacity rather than tipping. Ratings are based on SAE Standard No. J/ISO 10567. Rated loads do not exceed 87% of hydraulic lift
capacity or 75% of tipping load.
