Product Feature
Komatsu Auto Idle Shutdown
Komatsu auto idle shutdown automatically shuts the engine down after idling for a set period of time to reduce unnecessary fuel consumption and exhaust emissions. The amount of time before the engine is shutdown can be easily programmed from 5 to 60 minutes.
Fuel Consumption
Reduced by 6%
Komatsu Harmony
All major components are designed and manufactured by Komatsu.
Arm rest with simple height adjustment function
A knob and plunger on the armrests allows easy height adjustment without the use of tools.
Switchable Display Modes
The main screen display mode can be changed by pressing the pressing the F3 key.
Operator Identification Function
An operator identification ID can be set up for each operator, and used to manage operation information of individual machines using KOMTRAX data. Data sent from KOMTRAX can be used to analyze operation status by operator as well as by machine.
