DO MORE WITH LESS FUEL

  • Get up to 15 percent higher fuel efficiency – more work per unit of fuel – than the 336F Straight Boom version.
  • Match the excavator to the job with three power modes – Power, Smart, and Eco. Smart mode automatically matches engine and hydraulic power to working conditions, providing max power when needed and reducing power when it isn’t to help save fuel.
  • Auxiliary hydraulic options give you the versatility to use a wide range of Cat attachments, including the heaviest tools needed for demolition work.
  • Don’t let the temperature stop you from working. This excavator has a high-ambient capability of 52° C (125° F) and cold start capability of –18° C (0° F).
  • Advansys™ bucket tips increase production and lower costs with more tip life.
  • Know where your work tools are and how much you use them; the machine can track all attachments equipped with the Cat Locator device.
  • 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.

WORK IN COMFORT

  • The demolition cab comes with a deluxe heated seat andclimate control.
  • Get in and out of the cab easier with the tip-up left console.
  • Advanced viscous mounts reduce cab vibration up to 50 percent over previous excavator models.
  • Control the excavator comfortably with easy-to-reach controls all located in front of you.
  • 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 personal devices and make hands-free calls.

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 operator ID; the excavator will remember them every timeyou go to work.
  • Automatic hydraulic oil warm up gets you to work faster in cold temperatures and helps prolong the life of components.
  • Navigate quickly on the standard high-resolution 254 mm (10 in) 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 fi ngertips in the touchscreen monitor.

LOWER MAINTENANCE COSTS

  • Expect up to 20 percent less maintenance cost than the 336F Straight Boom due to extended and synchronized service intervals and smaller fluid quantities (savings calculated over 12,000 machine hours).
  • Check hydraulic system oil and easily drain fuel system water and fuel tank water from ground level.
  • Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
  • Change all fuel filters at a synchronized 1,000 hours. Oil and fuel filters grouped and located on right-hand side of machine for easy maintenance.
  • The new air intake filter with pre-cleaner has double the dust holding capacity of the previous air intake 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 percent longer than previous filter designs.
  • The high-efficiency hydraulic fan has an optional automatic reverse function to keep cores free from debris, eliminating the need for any operator interaction.
  • S·O·S ports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.

BUILT-IN SAFETY FEATURES

  • The front windshield and top hatch are made with EN 356 P5A glazing for enhanced impact resistance.
  • The standard ROPS cab meets ISO 12117-2:2008 requirements.
  • The standard FOGS enhances overhead safety.
  • A travel direction indicator helps operators know which way to activate the travel levers.
  • Enjoy great visibility with the help of smaller cab pillars, larger windows, the standard parallel roof wiper and washer, and a flat engine hood design.
  • A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
  • Rearview and sideview cameras are standard. Upgrade to 360° visibility and you’ll easily visualize objects and personnel around the excavator in a single view.
  • Serrated steps and anti-skid punch plate on the service platform help prevent slipping.
