Hydraulic FiltersHydraulic circuits use high-quality hydraulic filters. A suction filter is

incorporated in the suction line, and full-flow filters in the returnline and swing/travel motor drain lines.

BACKHOE ATTACHMENTSBoom and arms are of welded, box-section design.

15’ 1” (4.60 m) boom, and 8’ 3” (2.52 m) and 9’ 11” (3.01 m) arms are available.

Higher Productivity Zaxis uses the latest technologies to achieve lower total operationalcosts while boosting productivity. The large Isuzu intercooler-equippedengine provides an excellent balance of power and fuel efficiency.

Cab Comfort The easy-to-read monitor panel and switches are located near the operator to minimize fatigue and enhance operator control. Noise levels inside the cabin have been reduced. The Auto-control air conditioner allows you to set a specific temperature, then forget it. Bi-level air ducts are positioned throughout the cab to promote even air flow.

Cab Safety The CRES (Center pillar Reinforced Structure) rigid cab is designed with safety in mind. The closed-section pillar and reinforcing members at central areas withstand vertical and horizontal external forces. This can help reduce the potential of operator injury in the event of an accident.

Operator Command The newly refined hydraulic system gives the operator unprecedented control. The bucket regenerative system makes light-duty operation quicker.

Increased Travel and Swing Power Armed with plenty of dependable power for travel and swingoperations, the Zaxis 120 is ready for the toughest of terrains and jobsites thanks to improved travel motors and swing reduction gear. It has9% more swing torque and 4% more travel power than the EX120.

Auto Acceleration and Auto Idle Engine speed isautomatically controlled inresponse to the amount oflever operation. This helpsreduce fuel consumption,especially during light-loadwork. The Auto-idle controlreduces the engine speedautomatically to save energywhen the lever is in neutral.

Lower Operating Costs Reduced fuel consumption, a strengthened main frame, frontattachment, and undercarriage, longer lubrication intervals, 4,000-hourhydraulic oil and 1,000-hour hydraulic oil filters all work together toextend the durability of Zaxis while reducing running and repair costs.

Work Modes Two modes simplify excavating operations. Select the “Digging” mode for smooth and speedy front operations or“Attachment” to use a wide variety of tools such as breakers,compactors, and crushers.

The powerful engine andhydraulic system work togetherto bring the maximum amountof excavating forces to thetoughest of job sites.

Cab design both guards the operator and contributesto efficient operation through its comfortable,ergonomic layout and its CRES design.

A low-noise muffler and the Isuzu Tier 2 emissionscontrol engine ensure a quieter, moreenvironmentally friendly excavator. Plastic partsare labeled for easy recycling. Wiring is lead-free.
