Rear dual-post ROPS, head guard canopy, and an auto rewinding seat belt are installed as standard equipment. INCREASED RELIABILITY AND SERVICEABILITY Easy-to-maintain designs allow quick and easy daily checks and maintenance. Single-touch full-open hood You can open the engine hood using a single-touch operation, and you can quickly complete daily checks and maintenance of the machine. Anti-slip floor mat Side-by-side cooling system The oil cooler and radiator are installed side-by-side in the optimum position for ease of cleaning. They provide high cooling efficiency. Components that prevent machine failure and improve machine reliability Face-seal type hydraulic hose / tube connectors Greatly increases the reliability of hydraulic line system. Large counterweight to protect the rear and rear side sections of the machine The machine has a large counterweight to protect the main body should it be impacted while moving backward. Also, the rear combination lamps and exhaust pipes are built into the counterweight so that damage to them will be minimized in the case of a collision. Remote and collective arrangement of filters All filters are mounted in a remote place collectively. You can easily check and replace the filters. DT connectors DT connectors with very tight sealing performance prevent failures of the electrical system. Automatic air bleeding system Excellent visibility for secure and reliable operations Frontal visibility is clear thanks to the rear dual-post ROPS canopy design and the optimized layout of the monitor unit. The cab machine (optional) uses pillar-less glass for both the front and rear windows resulting in a very wide field of view. Also, the round-surface design of the engine hood realizes excellent rearward visibility. New boom design permitting excellent front visibility The machine has a new "Delta boom" so that you can easily observe the front tires and the bucket side plates from the operator's seat. Delta boom Repeating 20-second engine cranking with the starting switch set to START position two or three times bleeds air from the fuel system. This system allows you to restart the engine quickly even when the machine has run out of fuel. Tapered roller bearings Highly durable tapered roller bearings are used in the frame center hinge. As the greasing interval of tapered roller bearings is 1, 000 hours, maintenance can be minimized. Pre-cleaner (optional) High braking performance assures reliable operation. HST travel brake When you release the accelerator pedal, the HST (hydrostatic transmission) travel brake is automatically activated. The pre-cleaner can remove straw and sawdust in dusty environments and prevents early clogging of the air cleaner. Note: The pre-cleaner cannot be installed on the cab specification machine. Sealed wet-type disc brakes featuring high braking performance and long service life The machine uses sealed wet-type disc brakes that feature high braking performance even when the machine is on soft or wet ground. The brake discs have high wear resistance and long service life. ENVIRONMENTAL FEATURES Low Emission Engine This engine meets EPA Tier 3 and EU Stage 3A emissions regulations, without sacrificing power or machine productivity. Canopy Hand parking brake The machine has a hand brake lever allowing for easy parking. [. . . ] Emergency brake: Parking brake is commonly used. STEERING SYSTEM Type . Full-hydraulic power steering independent of engine rpm Steering angle . 42. 5° each direction Minimum turning radius at the center of outside tire . 3125 mm 10'3" All dimensions, weights, and performance values based on SAE J732c and J742b standards.
