Benefits & Features
High Performance with Lower Fuel Consumption
• Use up to 20 percent less fuel than the 323F excavator.
• Increase operating efficiency up to 45 percent with standard Cat Connect technologies that lower operator fatigue and your operating costs, including fuel consumption and daily maintenance.
• The C7.1 engine can run on biodiesel up to B20 and meets U.S.EPA Tier 4 Final and EU Stage IV emission standards with an aftertreatment system that requires no maintenance or downtime.
• The advanced hydraulic system provides the optimum balance of power and effi ciency while giving you the control you need forprecise digging requirements.
• Match the excavator to the job with power modes; let Smart mode automatically match engine and hydraulic power to digging conditions.
• Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.
• Available SmartBoom™ lets the boom freely travel up and down
without using any pump flow so operators can focus on stick and
bucket work. The benefits are reduced operator stress and reduced
fuel consumption.
• Don’t let the temperature stop you from working. The excavator has
a standard high-ambient temperature capability of 52° C (125° F)
and cold start capability of –18° C (0° F). An optional –32° C (–25° F)
cold start package is available.
Boost Efficiency and Boost Productivity with Integrated Cat Connect
• Boost productivity up to 45 percent versus traditional grading withstandard Cat GRADE with 2D system – includes indicate-only and laser capability.
– Dig with guidance to depth, slope, and horizontal distance to grade.
You can set up to four different target depth and slope offsets to help save time and money. When the job calls for a different offset, quickly switch through the monitor and get to work.
– The 2D system is upgradable to Cat GRADE with Advanced 2D
orCat GRADE with 3D.
• Standard Grade Assist:
– Stay on grade – simply and effortlessly – with single-lever digging.
– Set your desired bucket angle and let Bucket Assist automatically
maintain the angle in sloping, leveling, fine grading, and trenching
applications for easy, accurate, and fast jobs.
– Keep the tracks on ground in lifting and hard digging with BoomAssist.
– Automatically stop excavator swing at operator-defined set points in truck loading and trenching applications with Swing Assist, which will help you use less effort and consume less fuel.
• Standard Cat PAYLOAD on-board weighing system:
– Achieve precise load targets and increase loading efficiency with on-the-go weighing and real-time estimates of your payload without swinging.
– Track your daily productivity such as truck target weights and
load/cycle counts.
– Calibration can be performed in a matter of minutes.
– Combine Payload with VisionLink®
and remotely manage your production targets.
• Upgrade to optional Cat GRADE with Advanced 2D:
– Create and edit grade designs with ease on a second high resolution 254 mm (10 in) touchscreen monitor.
• Upgrade to optional Cat GRADE with 3D:
– Create and edit designs with ease and see the front linkage’s full range of motion on a second high-resolution 254 mm (10 in) touchscreen monitor.
– Use the excavator’s onboard cell technology to quickly connect to 3D services like Trimble Connected Community or Virtual Reference Station.
– Know the excavator’s exact position relative to GPS and
GLONASS systems.
– The machine automatically compensates for excavator pitch
androll caused by sloping ground conditions.
– Antennas have theft-prevention bolts; a special tool makes them
easy for the owner to remove at the end of a shift.
• Remote Services:
– Remote Troubleshoot connects you to a dealer service pro to help solve your problem and quickly get you to work.
– Remote Flash works around your schedule to ensure your machine’s software is up to date for optimal performance.
– The Cat App helps you manage fleet location, hours, and maintenance schedules; it also alerts you for required maintenance and even allows you to request service from your local Cat dealer.
• Standard Product Link™ provides location, machine hours, fuel usage, productivity, idle time, diagnostic codes, and other machine data on demand through VisionLink online interface, helping you improve job site efficiency with lower operating costs.

Simple to Operate
• Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
• Program your power mode and joystick preferences using OperatorID; the excavator will remember what you set each time
you go to work.
• Navigate quickly on the standard high-resolution 254 mm (10 in)
touchscreen monitor, or with the aid of the jog dial control.
• A second 254 mm (10 in) monitor is available for the advanced gradecontrol.
• Not sure how a function works or how to maintain the excavator?
Always have the operator’s manual at your fingertips in the touchscreen monitor.

Maintenance
• Expect up to 20 percent less maintenance cost than the 323F.
(Savings calculated over 12,000 machine hours.)
• Do all daily maintenance at ground level.
• Check engine oil level quickly and safely with the new ground-level
engine oil dipstick; fill and check engine oil on top of the machine
with a conveniently located second dipstick.

• High-efficiency cooling fans run only when needed; you can program intervals so they automatically reverse to keep cores clean without interrupting your work.
• S·O·S SMports are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.
Safety
• Lift Assist helps you avoid tipping. With visual and auditory alerts,you’ll know if your load is within the excavator’s safe working range limits.
• The standard 2D E-fence feature integrated right out of the factoryprevents the excavator from moving outside operator defined set points.
• Access 100 percent of daily maintenance points from ground level – no need for you to climb on top of the excavator.
• The standard ROPS cab meets ISO 12117-2:2008 requirements.
• Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab pillars, larger windows,
anda flat engine hood design.
• The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
• Ground-level shut-off switch stops all fuel to the engine when activated and shuts down the machine.
• A rearview camera and a right-side-view camera are standard.
Upgrade to 360° visibility and you’ll easily visualize objects and personnel around the excavator in a single view.
