Wide, spacious cab with excellent visibility

Wide windows in the front, side and back, plus plenty of

space in the richly upholstered interior, provide quiet, com-

fortable environment from which to see and control every

aspect of operation. Front under view mirrors and side

under view mirrors have been added to improve safety.

Ergonomically designed cab

The ergonomically designed operator's compartment makes

it very easy and comfortable for the operator to use all the

controls. The result is more confident operation and greater

productivity.

Easy-to-See instrument panel

The instrument panel makes it easy to monitor critical

machine functions. In addition, a caution light warns the

operator of any problems that may occur. Problems are

recorded in the monitor and indicated as service codes.

This makes the machine user friendly and easy to service.

Ideal driving position settings

The 5-way adjustable operator seat and the tilt-telescopic

steering column provide an optimum driving posture, for

increased driving comfort and more control over machine

operation. The suspension seat dampens vibrations transmit-

ted from the machine and reduces operator fatigue as well

as holding the operator securely to assure confident opera-

tion.

78mm

3" width seat belt is provided as standard equip-

ment.

Electric body dump control

The low effort lever makes dumping

easy. A positioning sensor is

installed for dump body control

which significantly reduces the

shock made by the lowering of the

dump body.

K-ATOMiCS with "Skip-shift" function

An electronically controlled valve is provided for each clutch

pack in the transmission for independent clutch engage-

ment/disengagement. It enables an ideal change in clutch

modulation pressure and torque cut-off timing in response to

travel conditions. This system and newly added “skip-shift”

function ensure smooth shifting and responsive acceleration.

Hydropneumatic suspension for 
all terrains

The hydropneumatic suspension 

assures a comfortable ride even over

rough terrain and ensures maximum

productivity and operator 

confidence.

Viscous cab mounts

Viscous mounts reduce the noise

transmitted to the cab and achieve a

quiet 77 dB(A) noise level.

Built-in 
ROPS/FOPS cab

These structures con-

form to ISO3471 ROPS

standard, and ISO 3449

FOPS standard.

Supplementary steering and secondary brake

Supplementary steering and secondary brake are standard

features.

Steering: ISO 5010, SAE J1511

Brakes: ISO 3450

Three-mode hydropneumatic suspension 
(Automatic suspension) 

(Option)

Suspension mode is automatically switched to one of three

stages (soft, medium and hard) according to load and 

operating conditions, for a more comfortable and stable ride.

"Skip-shift" function 

Optimum travel speed automatically selected in response to

angle of ascent.

Reduced frequen-

cy of downshift

and smoother

operation are pro-

vided.
