PERFORMANCE WITH LESS FUEL

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 for precise digging requirements.
Valve priority puts hydraulic pressure and flow where you command it to go for fast lightto 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 Cat attachments.
Product Link™ comes standard so you can remotely monitor machine health, location, hours, and fuel consumption on demand through the VisionLink® online interface.

LOWER MAINTENANCE COSTS

Expect up to 25percent less maintenance cost than the 320E (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.
No required maintenance on the Cat Clean Emissions Module.
Using Cat genuine oil and filters and doing your typical S∙O∙S monitoring will double the current service interval to 1,000 hours, giving you greater uptime to do more work.
The new hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000 hour replacement interval – 50 percent longer than previous filter designs.
The new high-efficiency electric cooling fans only run when needed and reverse to keep cores free from debris.
S·O·S ports simplify maintenance and allow for quick, easy extraction of samples for fluid analysis.

RELIABILITY YOU CAN COUNT ON

Work up to 3000 m (9,840 ft) above sea level without de-rating.
Standard high-ambient temperature capability is 52º C (125º F) with cold 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.
Three levels of fuel filtration protect the engine from dirty diesel fuel.
Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
The center track guiding guard helps 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.

SAFELY HOME EVERY DAY

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 on the 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 is standard, and a right-side-view camera is optional.
The new right-hand service platform design provides easy, safe, and quick access to upper service platform; the service platformsteps use anti-skid punch plate to prevent slipping.
The handrails comply with ISO 2867:2011 requirements.
The lower frame meets ISO 15818:2017 lifting and tie-down requirements.

SIMPLE TO OPERATE

Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
Program each joystick button, including response and pattern, using Operator ID; it will also remember climate control fan and radio settings.
Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor or with the aid of the jog dial control.
Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds -- all to prevent wear and tear on the attachment and excavator.
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.
The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The Cat App on your phone will locate the device automatically.

DESIGNED FOR OPERATORS

The Comfort cab has a wide seat that adjusts for operators of all sizes.
Control the excavator comfortably with easy-to-reach controls all located in front of you.
Standard automatic climate control keeps you at the righttemperature 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, documentholder, bottle holder, and coat hook are also provided.
Use the standard radio’s USB ports and Bluetooth® technology to connect to personal devices.
