ompact yet Powerful itachi applied all its excavator expertise in the design of the new zero-tail mini excavators ZXIS0U-2 and ZXIS50U-2. These machines meet customer demands for operating comfort, enhanced safety and easier maintenance. The series complies with the latest emission regulations, noise suppression standards and ROPS/FOPS standards. Operators have superior control over the machine from the relaxed seat. Owners enjoy a lower cost of ownership due to the machine s durability and easy maintenance. Single Swing Pin single large swing pin is used to eliminate jerking. utomatic Travel Speed ontrol at igh Speed (Standard) uring high-speed travel, when the load is increased for steering for example, travel speed is lowered automatically and smoothly. When the load is decreased, travel speed is resumed accordingly. urable Flat-ottom ucket Sideplate Welding ucket bottom Wear plate Job-Proven N ushings The flat-bottom bucket is provided standard to minimize bucket bottom wear. Wide wear plates are welded to the bucket bottom for increased durability. The field-proven N bushing, a itachi original, is utilized at each front pin join to reduce jerking and servicing. Lubricating interval is a long 500 hours nlarged ounterweight and Weighted Undercarriage ox-section frame The newly developed box-section frame is adopted, combining low weight and high durability. The enlarged counterweight and weighted undercarriage help lower the center of gravity and increase stability. N ushing Oil Pin The N bushing, another example of innovative technology developed by itachi, features long life and high durability. igh-viscosity oil is vacuum impregnated in sintered high-hardness metal. uring operation oil oozes come from the pores of the bushing into the clearance between pin and bushing for self-lubrication. -section frame nlarged counterweight dditional ounterweight (Option) When using a heavy front attachment such as a fork grapple, the additional counterweight is easily mounted for higher stability. uto-idle Saves Fuel onsumption When shifting the control lever to neutral, engine speed is lowered to idling speed to save fuel consumption and reduce emissions and noise. This feature is advantage when working in urban residential districts. New-Structure Rubber rawlers onventional The itachi-developed rubber crawlers are highly durable, featuring a steelcored structure that protects shoe edges rack Steel core from being damaged even when riding Force Rubber on curbs. urb New structure Steel core Force urb Rubber cting force is diverted to reduce crack.

Operator omfort and Safety rgonomic ontrols onveniently Located Foot Pedals While traveling with foot pedals, the operator can control the front attachment with hands. The foot pedals, when not in use, can be folded away for increased foot space. Rubber Mounted Floor The cabin rests on shock-absorbing rubber mounts to ensure comfortable operation. asy-to-read Monitor The operator can always check machine conditions at a glance. Fuel level, coolant temperature and the status of various other indicators are clearly displayed on the large L monitor placed in the front right position. ir onditioner (abin Version) ompact yet ample-capacity air conditioner is provided standard. The full- 360 rotatable air outlet also serves as a defroster, maintaining operator comfort all the year round. Functionally Located Switches Various switches are located within reach of the operator for convenience of the operator without need for repositioning. Folded Large abin oor The door opens in two steps and has increased width of 60 mm, allowing easy entry. Miscellaneous evices ROPS/FOPS abin and anopy oth canopy and cabin conform to the latest ROPS, FOPS and TOPS standards. These protect the operator in case of roll-over; tip-over and from falling objects. The seat belt protects the operator as well. The operator s cabin and canopy, complying with the international standards, are mounted to protect the operator in the case of tipping. Seat backrest box rink can holder Seat belt shtray (cabin) Improved Visibility with Roof Sun Visor (anopy) The Sun visor, an integral part of the roof, gives better upward visibility. The overhang roof keeps the operator s knees dry in light rain. Pilot-ontrol Shut-Off Lever ll operations front, swing, travel and blade can be shut off by locking the pilot control shutoff valve. This effectively prevents accidental lever control. Neutral ngine Start System The engine can start only when the pilot control shutoff lever is locked, This is called the neutral engine start system. This eliminates unexpected lurching when the engine suddenly starts when unconscious touching the control lever. Tool box (canopy) Side Toolbox Slip-resistant tape Swing/Travel Parking rakes (Standard) The swing parking brake and travel parking brake are both provided standard for enhanced safety. 5
asy Maintenance Parts and Service Tilt-Up Floor The cabin floor can be tilted up for easy, quick servicing even in the case of an emergency. The floor can be tilted up to 50 to allow the operator to work under the cabin floor. It also gives direct access to the swing mechanism and starter motor behind the engine located under the cabin floor. This design reduces inspection and maintenance time. Over the years itachi gained experience in one of the most competitive service markets in the world: Japan. Using our know-how in dealing directly with customers, we have created a worldwide support system that is highly effective and efficient. More than 50 dealers all over the world have highly trained technicians and high parts availability. ontact your itachi dealer for detailed information about service programs available for your area and machine. Not all services and/or programs are available in every region or for all machines. Simplified aily Maintenance The engine cover can slide up and down for quick servicing even in confined space. No more swing-open cover that obstructs maintenance and servicing jobs. The right side cover swings open for a quick battery check. Uses Tracks Promoting asy Mud Removal The X-beam track frame is rounded for smooth mud removal. One-sided slope on the side track frame promotes mud sliding-off, minimizing mud packing problem. This shortens machine washing time and reduces disposal costs, too. To get the most out of your machine, you need genuine itachi parts. In most cases there is a Reinforced -Shaped Frame The machine frame is reinforced with a -shaped frame that protects against damage and impact by obstructions. asy to Repair Steel over steel cover is utilized for tough operation, allowing easy repair if damaged. The steel cover is durable, recyclable and economical. Swing motor ontrol valve Fuel tank itachi dealer in your area that has the required part in stock. itachi minimizes the delivery time for any part by connecting its parts depots in Japan, Singapore, The Netherlands and North merica by a on-line system sharing information on the number and type of available parts.
