 Always add the specified amount of oil.
Both too much and too little oil may cause problems.
 If the oil in the work equipment is not clear, there is probably
water or air entering the circuit. In such cases, please consult
your Komatsu distributor for information.
 When changing the oil, always replace the related filters at
the same time.
 We recommend having the oil analysed periodically to check
the condition of the machine. For those who wish to use this
service, please contact your Komatsu distributor.
 When using commercially available oil, it may be necessary
to reduce the oil change interval.
 We recommend using the Komatsu oil clinic for a detailed
check of the oil characteristics.
Fuel
 The fuel pump is a precision instrument. It does not work
properly if the fuel contains water or dirt.
 Be careful to prevent fuel contamination during storage or
when refilling.
 Always use the fuel specified in the Operation and Mainte-
nance Manual.
If the fuel is used at temperatures lower than the specified
temperature (particularly at temperatures below -15 °C), the
fuel will solidify.
If the fuel is used at temperatures higher than the specified
temperature, its viscosity will decrease. This may cause a
loss of output performance.
 To prevent the moisture in the air from condensing and form-
ing water inside the fuel tank, always fill the fuel tank after
completing the day's work.
 Before starting the engine, or when 10 minutes have passed
after adding fuel, drain the sediment and water from the fuel
tank.
 If the engine runs out of fuel, or after the filters have been
replaced, it is necessary to bleed the air from the circuit.
 If there is any foreign material in the fuel tank, flush the tank
and the fuel system.
NOTICE
Exclusively use diesel fuel with an extremely low sulphur content
(10 ppm). Never use any other fuel. Using low-viscosity fuel with
poor lubricating characteristics will cause a marked reduction in
the durability of the engine.
