3 More Production with Less Fuel. Meeting Two Copeting Needs 7% Down Fuel Consuption* New electronically-controlled engine 22% Increase in Max. Torque + Low Speed ZX70-5G ZX70 Engine Torque Isochronous Control Range Engine torque vs. engine in-1 Engine in-1 Hitachi fuel-saving technology is ore evolved than ever. The electronically controlled engine can curb fuel consuption behind the electronic governor, clutch fan, and isochronous control, which is one of fuel-saving technologies that can autoatically control engine rp through the electronic governor. This can suppress wasteful engine speed increase when big output is not needed, leading to less fuel consuption. *Hitachi easureents in P ode under standard digging test conditions 22% Up Engine Torque The new engine is designed to increase its axiu torque to keep running without speed drop at high altitudes with thin air and in hot suer season. At its axiu torque, the speed is kept low to ensure stable perforance even under heavy loads. Iproved Heat Balance Even at high teperatures in suer or in continuous long hours operation, the ZX70 can lessen overheating, as cooling efficiency increases: heat balance is up 4% in engine coolant, and up 12% in hydraulic oil, copared to the conventional. Covers with higher cooling efficiency Low-Effort Pilot Lever The new fingertip-control pilot lever reduces operator fatigue in long hours operation. This pilot lever resebles the one proven on the ZX200 in the larger class. Shown equipped with an optional 4-side rainforced ar and pre-cleaner. 4 5

4 Enhanced Operator Cofort with Refined Controls and Cab Interior Highest Criteria of Sturdiness and Durability Gives Higher Productivity WC Theral Spraying at Ar-Bucket Joint WC (Tungsten-Carbide) theral spraying is applied on surfaces of the ar-bucket joint to for hardening layers to reduce wear and jerking significantly.

5 Hitachi Heritage of High Maintainability to Reduce Downtie Hitachi Support Chain Hitachi Support Chain is a full custoer support syste offered after buying a Hitachi achine. Fuel Double-Filters (Standard) Parts and Service Hitachi full custoer support is available every area on the globe for full custoer satisfaction through Hitachi local dealers. Fuel double-filters are utilized in a fuel line fro fuel tank to engine to avoid plugging. Also, a solenoid fuel pup is provided standard to release air if water is ixed in fuel or fuel runs out. Dust-Proof Indoor Net The radiator is provided with a detachable dust protective net at its front to avoid dust entry. The net is ade of three-split type for easy, quick servicing. An air nozzle port at the radiator top facilitates cleaning. Easy-to-Clean Big Fuel Tank The fuel tank has the aple capacity of 135 litters. Its inlet is sealed with a keyed cap for water proof type. At the botto of the fuel tank a drain cock, which serves to easily discharge containants inside, and a bolted cleaning port for easy opening and cleaning. Shown equipped with an optional pre-cleaner. Fuel Cap Parts Hitachi Global Online Network, a parts supply syste, is linked with Japan Parts Center, overseas depots and over 150 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. Battery Disconnect Switch (Optional) This battery disconnect switch is provided to avoid battery discharging and protect harnesses when the achine is not in use in winter or in long-ter storage.
