Match the excavator's operation to your digging style by adjusting the joystick response and programming the function of each joystick button.
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.
Easily use the monitor to change the joystick pattern from the cab. You can choose two-way or four-way patterns options. Store your pattern preference and let the machine automatically set the pattern when you log in with your unique Operator ID.
Extended maintenance intervals reduce maintenance costs by 20% over the Cat 320F excavator. (20% savings calculated over 12000 machine hours).
Reversing electric cooling fans make it easy to clean radiator, oil coolers, and condensers.
An all-new engine air cleaner with integrated pre-cleaner has twice the life of radial seal air cleaners.
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 3000 hour replacement interval – 50% longer than previous filter designs.
Track your excavator's filter life and maintenance intervals can via the in-cab monitor.
Check engine oil level quickly and safely with the new engine oil dip stick located on ground level.
S·O·S ports with extended sampling intervals are on ground level, simplifying maintenance and allows for quick easy extraction of samples for fluid analysis.
Work safely under structures or near traffic with the standard 2D E-fence feature integrated right out of the factory, which prevents any part of the excavator from moving outside operator-defined set points, avoiding hazards and jobsite accidents.
Access 100% of daily maintenance points from ground level – no need for you to climb on top of 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, and a 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 is standard and upgradable to an optional 360° visibility camera for visibility all around the excavator, allowing the operator to easily visualize objects and personnel around the excavator in a single view.
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 requirements.
