Specified CapacityTotal amount of oil including oil for components and piping.
Refill CapacityAmount of oil needed to refill system during normal maintenance.
Other equipment may be necessary when operating the machine at temperatures below -20°C. Consult your Komatsu distribu-
tor for your specific needs.
NOTE Use only diesel fuel. The engine mounted on this machine employs electronic control and a high
pressure fuel injection device to obtain good fuel consumption and good exhaust characteristics.
For this reason, it requires high precision for the parts and good lubrication. If kerosene or other
fuel with low lubricating ability is used, there will be a significant drop in durability.
