RECOMMENDED FUEL, COOLANT, AND LUBRICANT
Komatsu genuine oils are adjusted to maintain the reliability and durability of Komatsu construction equipment
and components.
In order to keep your machine in the best conditioner for long periods of time, it is essential to follow the
instructions in this Operation and Maintenance Manual.
Failure to follow these recommendations may result in shortened life or excess wear of the engine, power train,
cooling system, and/or other components.
Commercially available lubricant additives may be good for the machine, but they may also cause harm.
Komatsu does not recommend any commercially available lubricant additive.
Use the oil recommended according to the ambient temperature in the chart below.
Specified capacity means the total amount of oil including the oil in the tank and the piping. Refill capacity means
the amount of oil needed to refill the system during inspection and maintenance.
When starting the engine in temperatures below 0°C (32°F), be sure to use the recommended multi-grade oil,
even if the ambient temperature may become higher during the course of the day.
If the machine is operated at a temperature below -20°C (-4°F), a separate device is needed, so consult your
Komatsu distributor.
