Ecology and Economy Features
Low Emission Engine
A powerful, turbocharged and air-to-air aftercooled Komatsu SAA6D107E-1 provides 110 kW 148 HP. This engine meets EPA Tier 3 and EU stage 3A emissions regulations, without sacrificing power or machine productivity.
• Economy mode improves fuel consumption.
Low Operation Noise
The dynamic noise is reduced compared with the PC228US-3, realizing a low noise operation.
See page 4.
Easy Maintenance
• Long replacement interval of engine oil, engine oil filter, and hydraulic filter
• Remote mounted engine oil filter and fuel drain valve for easy access
• Equipped with the fuel pre-filter as standard (with water separator)
• Side-by-side cooling function enables only the cooling unit to be attached and detached.
• Equipped with the EMMS monitoring system.
See page 10.
Safety Features
• Anti-slip plates for safe work on machine
• Safety enhancement with large side-view, sidewise, and rear mirrors added.
See page 9.

Safety Operation
• Excellent safety and operability in tight quarters with small tail swing radius design
• Short protrusion of front and rear portion of the upper structure from the track at swing thanks to its round profile
• Small road width occupation for the work
See page 7.
Wide Working Ranges
Job sites that require a long upper reach, such as demolition and slope cutting also benefit from the increased digging and dumping ranges of the PC228US-3E0.
High Mobility
• Large drawbar pull and steering force display its ability when operating on a slope.
• Excellent mobility with automatic three-travel speed.
High Stability
The PC228US-3E0 offers exceptional lifting capacity and high stability with a large counterweight that requires no additional clearance.
See page 5.
Productivity Features
Multi-function Color Monitor
• Four working modes designed to match engine speed, pump delivery and system pressure.
• Power mode for maximum production/power
• Breaker mode for optimum engine rpm, hydraulic flow, and pressure
• Economy mode for lower fuel consumption and noise
• Lifting mode for high lifting capacity
See page 11.
Larger Comfortable Cab
• Low noise design cab with viscous cab mounting
• Sliding convex door facilitates easy entrance in confined areas.
• Large cab meets ISO working space stan­dards.
See page 8.
Komatsu’s PC228US-3E0 Series Hydraulic Excavators have a short tail swing profile, designed
specifically for work in confined areas. By reducing tail swing, the PC228US-3E0 can work in areas where conventional profile excavators would pose a safety risk.
Excellent Reliability and Durability
• High rigidity work equipment
• Sturdy frame structure
• Reliable Komatsu manufactured major components
• Highly reliable electronic devices
See page 12.
Komatsu Technology
Komatsu develops and produces all major
components, such as engines, electronics
and hydraulic components, in house.
With this “Komatsu Technology,” and adding
customer feedback, Komatsu is achieving
great advancements in technology.
To achieve both high levels of productivity and
economical performance, Komatsu has devel-
oped the main components with a total control
system.

Large Digging Force
The machine has a digging force equal to that of PC200-8.
Furthermore, the operator can increase the power by 8 %
using single-touch power increase function when requiring
an extra power.
Excellent Travel Performance
With large drawbar pull and automatic gearshift function that
changes the travel speed between Hi and Lo speed at the
optimum shift point according to the load, the machine can
travel over the sever job site. The machine can also travel
quickly and speedy and comfortably travel while making a
turn.

Working Mode Selection
The PC228US-3E0 excavator is equipped with four working
modes (P, E, L and B mode). Each mode is designed to
match engine speed, pump speed, and system pressure with
the current application. This provides the flexibility to match
equipment performance to the job at hand.
Economy Mode
Economy mode is environmentally friendly. Fuel consumption
is reduced 14% (compared with PC228US-3 Active mode).
Lifting Mode
When the lifting mode is selected, lifting capacity is
increased 7% by raising hydraulic pressure.
Breaker Mode
Flow can be adjusted from the cab to match various attach-
ment requirements.
