Notes: 1. Ratings are based on SAE J1097.
2. Lifting capacity of the ZAXIS Series does not exceed 75% of tipping load with the machine on firm, level ground or 87% full hydraulic capacity.
3. The load point is a hook (not standard equipment) located on the back of the bucket.
4. *Indicates load limited by hydraulic capacity.
5. 0 m = Ground.

Compact Body with Short Rear End
The compact short rear end design allows efficient operation even in confined spaces.
Clean and Powerful
The new engine complies with the Emission Regulations EU Stage III A
Powerful 3-Cylinder Engine with Ample Displacement
High dependability and availability are achieved behind the time-tested high-powered engine.
Quiet, Fuel-Efficient Operation
High Fuel Efficiency (Eco Zone)
The machine can get the job done with less fuel and more production. Optimal control of engine speed and torque as well as hydraulic pressure achieves high fuel efficiency and production. The new setting of the Eco Zone boosts fuel economy and operating efficiency.
Smooth Combined Operations
The proven 3-pump hydraulic system and arm regenerative circuit are further improved for more efficient simultaneous operations, including digging, leveling and wall cutting.
Hydraulic Pilot Control Levers
Hydraulic pilot operation levers provide smooth control and easy operation.
Automatic Travel Speed Control at High Speed
During 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.
Additional Counterweight (Optional)
When using a heavy front attachment such as a fork grapple, the additional counterweight is easily mounted for higher stability.
Additional counterweight: 190 kg
