The advantages at a glance. Exterior parts are treated with rust resistant undercoat and strong top coat. High quality paint assures good appearance.
Integrated ROPS/FOPS driver’s cab mounted on rubber bearings reduces noise and vibration. Noise level in the cab 76 dB(A) 95/27/EC.
4 cylinder KOMATSU low emission engine. Already conforms to the future EU standard.
The Z-kinematics assure high tearout force and fast dump, raise, down and tilt speed.
Gull wing engine side covers including rear fender and rear radiator grill fully open at a touch. These provide clean, easy and light maintenance.
A kick down switch on the boom lever shifts from forward 2nd to 1st gear at a touch and provides larger rim pull.
The engine, torque converter and transmission as well as the hydraulic equipment and electrical parts undergo strict quality control for enhanced reliability and durability.
Torque proportioning differentials in both axles enable a smooth ride in muddy or sandy terrain.
Fully automatic four gear shift transmission provides superior manoeuvrability.
Fully sealed wet disc type service and parking brakes provide full protection against dust. This ensures less maintenance and service.
Options • High quality, modern and fully auto-
matic air conditioning system assures always clean and the most comfort in the cab.
• ECSS reduces vibrations and protects driver and machine.
• Wide variety front attachments apply the machine to various applications.
