Long life fuel, oil, and air filters keep you working on the job longer.
Check the hydraulic system oil and easily drain fuel system water from ground level.
Track your excavator’s filter life and maintenance intervals via the in-cab monitor. The optional engine oil sensor tracks your oil levels to speed up your daily maintenance routine.
Change all fuel filters at a synchronized 1,000 hours. Filters are grouped together for easy maintenance.
The air intake filter with pre-cleaner has a high dust holding capacity.
The hydraulic oil filter provides improved filtration performance and anti-drain valves to keep oil clean when the filter is replaced.
The high-efficiency hydraulic fan has a standard automatic reverse function to keep cores free from debris, eliminating the need for any operator interaction.
Boost productivity with proactive service reminders. The Integrated vehicle health management system alerts the operator with step-by-step service guidance along with parts needed so you don't experience any unnecessary downtime.
S•O•S^SMports simplify maintenance and allow for quick, easy extraction of fluid samples for analysis.

The front windshield and roof window are made with P5A glazing for enhanced impact resistance.
A travel direction indicator helps operators know which way to activate the travel levers.
Enjoy great visibility in each swing direction and behind you with the help of smaller cab pillars and larger windows.
Standard Operator Protective Guards (OPG) protect the roof and front window in a demolition application while also maintaining visibility to the jobsite.
A ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
Rearview and right-hand-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.
