Abbrevia-
tion
Actual word spelled out
Purpose of use (major ap-
plicable machine (*1), or
component/system)
Explanation
ABS Anti-skid Brake System
Travel and brake When the tires skid (wheels stop rotating), the
brakes are released, and when the wheels start
to rotate, the brakes are applied again.
(HD, HM)
AISS
Automatic Idling Setting
System
Engine This function automatically sets the idle speed.
AJSS
Advanced Joystick
Steering System
Steering A lever is used to perform the steering operations
instead of a steering wheel. Moreover, it shifts
gear and changes direction (FORWARD or RE-
VERSE).
(WA)
ARAC
Automatic Retarder Ac-
celerator Control
Travel and brake When the accelerator pedal is released while the
machine is traveling downhill, this function auto-
matically applies the retarder with a constant
braking force.
(HD, HM)
ARSC
Automatic Retarder
Speed Control
Travel and brake When the accelerator pedal is released while the
machine is traveling downhill, this function auto-
matically applies the retarder to ensure that the
machine speed does not accelerate above the
speed set by the operator.
(HD, HM)
ASR
Automatic Spin Regula-
tor
Travel and brake When the tires spin on soft ground surfaces, this
function automatically uses the optimum braking
force to drive both wheels.
(HD, HM)
ATT Attachment Work equipment
A device that can be fixed onto the standard ma-
chine in order to enable it to do different jobs.
BCV
Brake cooling oil control
valve
Brake When the retarder is not being used, this valve
bypasses part of the brake cooling oil to reduce
the load on the hydraulic pump.
(HD)
CAN Controller Area Network
Communication and elec-
tronic control One of communication standards that is used in
the network on the machine.
CDR
Crankcase Depression
Regulator
Engine
A regulator valve which is installed to KCCV ven-
tilator. It is written as CDR valve and it is not
used independently.
CLSS
Closed-center Load
Sensing System
Hydraulic system
This system can simultaneously actuate multiple
actuators regardless of the load (provides better
combined operation than OLSS).
CRI Common Rail Injection Engine
Engine controller electronically controls supply
pump, common rail, and injector. This function
maintains optimum fuel injection amount and fuel
injection timing.
