Use up to 12 percent less fuel than the 330F Excavator in similar applications.

The C7.1 engine can run on biodiesel up to B20 and meets U.S. EPA Tier 4 Final, EU Stage IV, Japan 2014 (Tier 4 Final) and Korea Tier 4 Final emission standards with an after-treatment system that requires no maintenance or downtime.

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 light- to medium-load cycle times.

Match the excavator to the job with power modes; let Smart mode automatically match engine and hydraulic power to digging conditions.

Advansys™ bucket tips increase penetration and improve cycle times. Tip changes can be done quickly with a simple lug wrench instead of a hammer or special tool, improving safety and uptime.

Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments.

Standard Product Link™ collects data automatically and accurately from your assets – any type and any brand. Information such as location, hours, fuel usage, productivity, idle time, maintenance alerts, diagnostic codes, and machine health can be viewed online through web and mobile applications.


Work up to 3000 m (9,840 ft) above sea level without de-rating.

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.

Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.

Two 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 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.


The 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 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 to connect to personal devices.


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 Operator ID; the excavator will remember what you set each time you go to work.

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.

Find the tool you need – even if it’s hidden beneath overgrowth or debris. The optional Bluetooth reader can search for any work tool equipped with Cat asset tracking devices up to a range of 60 meters (200 feet).


Expect up to 20 percent less maintenance cost than the 330F (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.

Change all fuel filters at a synchronized 1,000 hours – a 100 percent increase over the 330F fuel filters.

Expect the new air intake filter with pre-cleaner to last up to 1,000 hours – a 100 percent increase over the previous filter.

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.

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 are on ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.


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 pillars, larger windows, and a flat engine hood design. A rearview camera and a right-side-view camera are standard.

New right 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 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.
