Detailed instructions for use are in the User's Guide.
[. . . ] This can be an advantage in stockpiling and ramp loading. As the machine moves and gains ground speed, the torque demand decreases and the low speed motor is effectively removed from the drive system by a clutch. At this point, the flow is going to the high-speed motor and the low-speed motor is not causing a drag on the system. An inching pedal gives the operator excellent simultaneous control of his travel and equipment hydraulic speeds. [. . . ] Komatsu loaders are manufactured with an integrated production system under a strict quality control system.

High-rigidity Frames and Loader Linkage
The front and rear frames and the loader linkage have got more torsional rigidity to provide resistance increased to stresses. Frame and loader linkage are designed to accommodate actual working loads, and simulated computer testing proves its strength.
Wet multi-disc brakes and fully hydraulic braking system mean lower maintenance costs and higher
reliability. Contaminants are kept out, reducing wear and resulting maintenance. Brakes require no adjustments for wear, meaning even lower maintenance. The parking brake is also an adjustment-free, wet multi-disc for high reliability and long life. Added reliability is designed into the braking system by the use of two independent hydraulic circuits, providing hydraulic backup should one of the circuits fail. Fully hydraulic brakes mean no air system to bleed, and no condensation of water in the system that can lead to contamination, corrosion, and freezing.

EMMS (Equipment Management Monitoring System)
Monitor is mounted in front of the operator for easy view, allowing the operator to easily check gauges and warning lights. A specially designed two-spoke steering wheel allows the operator to easily see the instrument panel. Maintenance Control and Troubleshooting Functions Action code display function: If an abnormality occurs,
Gull-wing Type Engine Side Doors Open Wide
The operator can open and close each gull-wing type engine side door easily with the assistance of a gas spring to perform daily service checks from the ground.
Cathion Electrodeposition Primer Paint/ Powder Coating Final Paint
Cathion electrodeposition paint is applied as a primer paint and powder coating is applied as topcoat to the exterior metal sheet parts. Some external parts are made of plastic providing long life and high impact resistance.
Sealed DT Connectors
Main harnesses and controller connectors are equipped with sealed DT connectors providing high reliability, water
the monitor displays action details on the character display at the center bottom of the monitor. Monitor function: Controller monitors engine oil pressure, coolant temperature, air cleaner clogging, etc. The wiper arm covers a large area to provide great visibility even on rainy days. The large cab area provides maximum space for the operator. The front mounted air conditioner was introduced to increase seat reclining and backward slide adjustment.
Rear-hinged Full Open Cab Doors
Entry and exit into the new komatsu cab starts with sloped staircase type steps and large diameter handrails for added comfort. The large cab doors are rear-hinged to open fully offering easy entry/exit and will not hamper visibility when operating the machine with the doors latched open.
Easy-to-operate Loader Control Mono-lever
A new mono-lever using PPC (Proportional Pressure Control) allows the operator to easily operate the work equipment, to reduce operator fatigue and to increase controllability. The adjustable wrist rest provides the operator with a variety of comfortable operating positions.
