Improved Rise / Run Performance
Arm rising while traveling for improved rise / run performance. On the new ZW Series,
10% higher rise/run performance can be expected, boosting loading efficiency and
increasing productivity.

Smoother Simultaneous Operations with Advanced Hydraulic Circuit
With the new parallel/tandem circuits, the lift arm and bucket can be operated at the same time, unlike conventional machines. This can remarkably increase digging and loading efficiency for higher production.

Selectable Clutch Cut-off Timing
Clutch cut-off timing can be selected from three options to suit various job conditions, including rapid operation on level ground, and surefooted operation on gradient.

• S mode:
  The clutch is cut-off at fast timing by
  depressing the pedal for speedy loading
  on level ground.
  

• N mode:
  The clutch is cut-off by depressing the
  pedal midway for surefooted loading on
  slope.
  

• D mode:
  The clutch is cut-off by depressing the
  pedal fully for dumping into a hopper
  on slope.
  

• OFF:
  The clutch is disabled.
  

Float System
The float system lets the lift arm follow up road irregularities by using its selfweight
only, without using its hydraulic circuit. This system is useful in soil-spill collecting during loading, and snow plowing.

Bucket Auto Leveller
The bucket can automatically be levelled parallel to the ground after rolling the bucket out. This can eliminate cumbersome bucket repositioning for efficient loading.

Lift Arm Auto Leveler (Optional)
The lift arm can automatically be raised and lowered to the preset level. By using the switches in the cab, high and low lift kickouts can be programmed.

Lift Arm Kick-Out System
The lift arm can automatically be raised up to the preset level. This function is
convenient when loading onto a dump truck, and when operating at confined job sites with restricted working height.

Restriction Valve
The restriction valve can effectively reduce shocks when moving the lift arm up and down. The bucket does not have a shockless circuit to allow efficient mud removal.

Ride Control System
The ride control reduces pitching and bouncing during travelling on rough terrain and
snow road by automatic control of the implement. Shocks and vibration can be well
suppressed for riding comfort.
