Monitor The new compact color monitor displays information in local language that is easy to read and understanding. Functions include: – 5 programmable “Quick Access” buttons for one-touch selection of favorite functions. – Filter and oil change warnings are displayed when the number of hours reaches the maintenance interval. – Tool select function allows the operator to select up to 10 pre-defined hydraulic work tools. – Adjustable braking characteristics enable the operator to select three levels of travel motor retarder aggressiveness when releasing the travel pedal. – Provides a rear camera view that is activated through the monitor menu. The optional camera is mounted on the counterweight. More >> link

Wipers The parallel wiper system maximizes visibility in poor weather conditions. The wiper virtually covers the entire front windshield, cleaning the operator’s immediate line of sight. More >> link

Viewing Area To maximize visibility, all glass is affixed directly to the cab, eliminating the use of window frames. Choice of fixed or easy-to-open split front windshield meets operator preference and application conditions. The 50/50 split front windshield allows both upper and lower portions to be stored in an overhead position and features the one-touch action release system. The 70/30 split front windshield stores the upper portion above the operator. The lower front windshield features a rounded design to maximize downward visibility and improves wiper coverage. Also features the one-touch action release system. The fixed front windshield comes with high-impact resistant laminated glass. A unique large skylight without cross bar provides superb upward visibility. The retractable sunscreen blocks direct sunlight. More >> link
