Specifications

Controls 

Proportional Pressure Control (PPC) joystick levers. The left hand joystick controls the travel, the right hand joystick controls the loader equipment. The PPC foot pedal controls the auxiliary hydraulic circuit for attachments. A safety system neutralizes all operations when the operator restraint bar is raised or the operator is not seated. Control pattern change valve is optional equipment. The optional control pattern splits the ground drive and loader controls between both joystick levers.

Easy to use Travel and Loader PPC Joysticks - Low effort Proportional Pressure Control (PPC) joysticks operate travel and loader operations. Easy to use PPC controls help operators of all skill levels work precisely and efficiently all day long – with minimum effort and reduced operator fatigue. 
Maximum Performance and Precise Control with HydrauMindTM - Komatsu’s smooth and precise HydrauMindTM system lets the operator feel the performance of the machine. The Closed Load Sensing System (CLSS) hydraulics are designed for both single and simultaneous movements which achieves unsurpassed controllability in the positioning of the bucket. 

Outstanding Visibility Work with confidence and increased productivity. The standard top and rear shatter resistant windows, large side screen area as well as a superior view of the bucket, cutting edge and corners give the operator an excellent 360° of job site visibility. 
Intelligent Operator Controls Komatsu has enhanced operator productivity and efficiency with their technologically advanced operator restraint bar. The operator restraint bar, incorporates a LCD gauge panel and warning light system, which is easily engaged and acts as a forearm rest. In addition, a Loader Arm Float Function control can be engaged on the joystick for enhanced back dragging or attachment applications. 
Two-Speed Travel - This Komatsu exclusive, in this size class, allows for low impact shift-on-the-go speed changes between 10.5 kph / 6.5 MPH work range and 16 kph / 10 MPH travel range. Improves load and carry cycle times and travel times between job sites. 
Enhanced Loader Arm and Bucket Control - The hydraulic self leveling (up only) bucket with 3,950 lb / 1792 kg breakout force enhances the productivity of the operator on the job site. The 45° dump and 30° rollback angles of the bucket allow for a faster dump cycle and load retention over rough terrain.
