2 Short Tail Swing and Ease of Control Boost Productivity in Tight Space The ZAXIS 7US is a short rear-end swing type excavator for productive job in tight space. No ore worrying about striking against surroundings. This increases productivity in confined areas and on narrow roads. The Hitachi hydraulic syste, featuring excellent controllability, allows for quick response to varying job needs, like powerful excavation and sooth grading. The cab is full of new designs, including ultifunction onitor and functional controls, for pleasant operation. The ZAXIS 7US is a fuel-thrifty achine too. The new electronically-controlled engine and new fuel-efficient hydraulics are adopted for less fuel consuption. The ZAXIS 7US will be your trusted partner when the going gets tough. More Production with Less Fuel. Meeting Two Copeting Needs Page 4- Short rear-end swing type excavator 9 % reduction in fuel consuption Increased front speeds Varied jobs, varied options No Coproise on Operator Cofort Page 8-9 ROPS-Copliant cab New easy-to-use ultifunction onitor Siplified Maintenance to Reduce Downtie Page Easy cleaning Reote concentrated servicing s Electric fuel refueling pup Hitachi Support Chain Page 14-1 Reote fleet anageent with global e-service Parts and services Shown equipped with 2.12 ar, extra piping, hose rupture valve, additional boo lights with cover, additional cab roof front lights, cab rear lights, rain guard and blade.

3 More Production with Less Fuel. Meeting Two Copeting Needs 180 Swing Min. swing radius * * Rear-end swing radius Short rear-end swing type excavator The ZAXIS 7US is a short rear-end swing type excavator for productive job in tight space. The upperstructure swings, rapidly or sooth, in response to changing job requireents through the advanced hydraulic technologies. The longer the operating hours, the higher the production. 9 %* Reduction in Fuel Consuption * When fitted with 1.62 ar 9%* Reduction in Fuel Consuption The new engine is teaed up with an electronic governor to save fuel. Electroniccontrol acceleration akes possible precision engine control and fuel saving. Fuel consuption coes down 9 %* fro the conventional ZX7US-3. With a switch on the onitor, the operator can choose the ECO ode and the PWR ode. Select the ECO ode for fuel-efficient operation and the PWR ode for speedy, powerful operation. *Copared to the conventional ZX7US-3 by JCMAS easuring ethod. Increased Front Speeds The Hitachi hydraulic syste has evolved even ore to increase front speeds. Hydraulic lines and piping are strealined to reduce resistance, increasing front speeds as follows. Ar roll-out speed : 28 % up Ar roll-in speed : 14 % up Boo lower speed : 16 % up Hose rupture valve (optional) Varied Jobs, Varied Options The hose rupture valve (optional) is added to reduce oil leaks, and prevent the attachent fro lowering, especially when a grapple or cutter is used, or when a front hose is punctured. Shown equipped with 2.12 ar, extra piping, hose rupture valve, additional boo lights with cover, additional cab roof front lights, rain guard and rear view irror and blade.

4 No Coproise on Operator Cofort ROPS-copliant Cab The ROPS-copliant cab protects you fro the potential risks of the job site. The Rollover Protective Structure (ROPS) is designed to protect the operator in the unlikely event of the achine tipping or rolling over. When getting in the Hitachi cab, the operator will feel cofortable and confident. There are plenty of refineents and iproveents in the cab. The seat and console are redesigned for easy operation. The operator does not feel confined through wide glass windows and door. A drink holder with hot and cool function, a lot ore air outlets are arranged to enhance operator cofort. A seat belt, pilot-controlled shutoff lever, swing parking brake, and travel parking brake are provided standard for safe operation. Neutral engine start feature enhances safety. The engine can start only when the shutoff lever is in its lock position. New, Easy-to-Use Multifunction Monitor New, Easy-to-Use Multifunction Monitor The new ulti-language, ultifunction onitoring syste is coposed of a 7-inch high-resolution color onitor and a ultifunction controller. The onitor allows the operator to check varying operating variables: oil teperature, fuel level, work ode, full-auto air conditioner, AM/FM radio, rear view onitor caera (optional) and aintenance support. Shown equipped with air suspension seat, attachent pedal, sun visor and blade lever.

5 Siplified Maintenance to Reduce Downtie Easy Cleaning The radiator front is fitted with a dust-proof indoor net, which can swing out for quick cleaning. Air conditioner filters and air cleaner are also easy to clean. The X-bea track top is inclined steeply to let ud slide away soothly. Reote Concentrated Servicing Points Dust-proof indoor net Servicing s are reote clustered on both sides of the achine for convenient ground-level aintenance, including filter replaceent and oil level check. Electric Fuel Refueling Pup (optional) An optional electric fuel refueling pup is housed inside the right cover for easy refueling fro an fuel dru. Electric fuel refilling pup (optional) Shown equipped with additional cab rear light, rear view onitor caera and blade.

6 Hitachi Support Chain Hitachi Support Chain is a full custoer support syste offered after buying a Hitachi achine. Reote Fleet Manageent with Global e-service (Optional) Easy Access to On-Site Machines through the Internet Main Features of Global e-service This on-line fleet anageent syste allows you to access each on-site achine fro a PC in your office. You can get its operating inforation and location to increase productivity of the fleet and reduce downtie. Operating data and log are sent to a Hitachi server for processing, and then to custoer and dealers around the world. This syste is available 24 hours a day, all the year around. Antenna(GPRS) or Satellite Machine Inforation Center, Hitachi Construction Machinery Functions Global e-service provides easy access to a achine on site, conveying operating inforation and log, including daily operating hours, fuel level, teperatures, pressures, and likes. Maintenance Maintenance data and log are displayed on a easy-to-read onitor screen, suggesting recoended aintenance for efficient fleet anageent. Custoer Operating Inforation Hitachi Construction Machinery Group and Dealers Quick access to inforation on reote achines Inforation sharing Internet Offering propt and adequate service Operation Maintenance Note: In Soe Regions, Global e-service Is Not Available by Local Regulations. Location Parts and Service Hitachi full custoer support is available every area on the globe for full custoer satisfaction through Hitachi local dealers. Parts Hitachi Global Online Network, a parts supply syste, is linked with Japan Parts Center, overseas depots and over 10 dealers abroad to deliver on-line parts inforation, including in-stock parts, order receptions, shipents and delivery period of over one illion parts and coponents. Genuine Hitachi Parts Genuine Hitachi parts, eeting Hitachi stringent quality standards, are guaranteed according to Hitachi warranty standards. The use of genuine Hitachi parts, including engine, fuel, hydraulic oil and filters, ay slash running costs, and extend achine life. Ground Engaging Tools (GETs) Hitachi provides an array of Hitachi Ground Engaging Tools developed and built for a variety of applications. Using high-quality, well-aintained GETs will help you get custoers' trust. Note: Soe dealers do not handle Hitachi GETs. Reanufactured Coponents Hitachi coponents are reanufactured according to the stringent reanufacturing standards at four factories around the world. They have high quality equivalent to new ones, and backed up by Hitachi warranty syste. Note: Soe dealers do not handle Hitachi Reanufactured Coponents. Service Extended Warranty HELP Hitachi Standard Warranty Syste is available on all new Hitachi achines. In addition, Hitachi offers Hitachi Extended Life Progras (HELPs) to suit custoer expectations protecting achines under tough operating conditions, avoiding unexpected downtie, and reducing repair costs. Note: Warranty conditions vary by equipent. Diagnostic Tools Maintenance Pro Electronic control syste needs quick on-site solutions, apart fro echanical repairs. Hitachi s Maintenance Pro can diagnose achine failures in a short tie by plugging a PC into a failed achine. Technical Training On-site servicing atters despite locations to keep the achine at peak perforance and reduce downtie. Technical Training Center (TTC), located in Japan, educates and trains service technicians and service support personnel coing fro Hitachi dealers and factories on the globe according to the international training progras
