BENEFITS & FEATURES
High Performance with Lower Fuel Consumption


• The excavator uses up to 20 percent less fuel than the 320F in similar applications.
• Match the excavator to the job with power modes; let Smart mode automatically match engine and hydraulic power to digging conditions.
• The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need forprecise digging requirements.
• Valve priority puts hydraulic pressure and flow where you command it to go for fast light- to medium-load cycle times.
• The engine meets U.S. EPA Tier 4 Final and EU Stage IV emission standards with an aftertreatment system that requires no operator input or downtime.
• Add auxiliary hydraulics to do more work with a range of Catattachments.
• Product Link™ comes standard so you can remotely monitor machine health, location, hours, and fuel consumption on demand through the VisionLink® online interface.

Reliable, High and Low, Heat and Cold


• Work up to 3000 m (9,840 ft) above sea level without de-rating.
• Standard high-ambient temperature capability is 52º C (125º F) withcold start capability at –32º C (–25º F).
• Auto warm up speeds up hydraulic oil warming in cold temperatures
and helps prolong the life of components.
• Grease sealed between track pins and bushings reduces travel noise
and prevents debris from entering to increase undercarriage life.
• The track guiding guards help keep the excavator track aligned when traveling and working on slopes.
• The sloped track frame prevents mud and debris accumulation,
helping reduce risk of track damage.

Work in Comfort in the All-New Cab


• The Comfort cab has a wide seat that adjusts for operators of allsizes.
• Control the excavator comfortably with easy-to-reach controls alllocated in front of you.
• Standard automatic climate control keeps you at the right temperature all shift long.
• Advanced viscous mounts reduce cab vibration by up to 50 percent
over previous excavator models.
• Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.
• Use the standard radio’s USB ports and Bluetooth® technology toconnect to personal devices.

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 203 mm (8in) touchscreen monitor or with the aid of the jog dial control.
• 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.
• Find the tool you need – even if it’s hidden beneath overgrowth or debris. The available Bluetooth reader can search for any work tool equipped with Cat asset tracking devices up to a range of 60 meters (200 feet).

Maintenance


• Expect up to 20 percent less maintenance cost than the 320F. (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.
• Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
• Do no required maintenance on the Cat Clean Emissions Module.
• Fuel filters are synchronized to be changed at 1,000 hours – doublethe interval from the previous filters.
• Expect the new air intake filter with precleaner to last up to 1,000hours – a 100 percent increase over the previous filter.
• The new hydraulic oil filter provides improved filtrationperformance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000 hour replacement interval – 50 percentlonger than previous filter designs.
• 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 ports simplify maintenance and allow for quick, easy extraction of samples for fluid analysis.

Safety


• Access 100 percent of daily maintenance points from ground level – no need for you to climb on top of the excavator.
• Keep your excavator secure with Operator ID. Use your PIN code
onthe monitor to enable the pushbutton starting feature.
• 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 posts and larger windows.
• A rearview camera and a right-side-view camera are standard.
• The new right-hand service platform design provides easy, safe, and quick access to upper service platform; the service platform steps use anti-skid punch plate to prevent slipping.
• The handrails comply with ISO 2867:2011 requirements.
