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 very friendly and easy to service.
Ideal driving position settings
The 5-way adjustable operator seat and the tilt-telescopic
steering column create an optimum driving posture, for
increased driving comfort and more control over the
machine’s operations. The suspension seat dampens vibra-
tions transmitted from the machine and reduces operator
fatigue as well as holding the operator securely to assure
confident operation.
78mm
3" width seat belt is provided as
standard equipment.
“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.
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
These structures con-
form to ISO3471 and
SAE J1040 ROPS stan-
dards, and ISO 3449
and SAE J231 FOPS
standards.
Electric body dump control lever
The low effort lever makes dumping
easy.
A positioning sensor is installed for
dump body control which significant-
ly reduces the shock made by the
lowering of the dump body.
Supplementary steering and secondary brakes
Supplementary steering and secondary brakes are standard
features.
Steering: ISO 5010, SAE J1511, SAE J53
Brakes: ISO 3450, SAE J1473
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.

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.
