PRECAUTIONS FOR MAINTENANCE
DURING MAINTENANCE
l When getting on or off the
machine, use the steps, hand
grips and ladders. Never jump on
or off the machine. If the steps,
hand grips, or ladder cannot be
used, use a stand to give firm
footing.
l If necessary, remove the cables
from the battery terminals. When
charging the battery, make sure
the area is well ventilated.
a Exhaust gas is dangerous. When
working inside, be particularly
careful to have good ventilation.
a When opening inspection covers,
stop the engine. If the hood or
other covers are fitted with a
lock, always apply the locks
securely when opening or closing
the hood or cover.
l Always stop the engine before
adjusting belt tension or before
checking or servicing the water
pump.
l Be particularly careful when
removing the radiator cap or the
hydraulic oil tank filler cap. If this
is done immediately after using
the machine, there is a danger
that boiling water or oil may
spurt out.
l Always release the pressure in
the circuit before checking or ser-
vicing the oil, water or air circuits.
l When the engine stops, the
water and oil in the circuit is hot,
so be careful not to get burned.
Wait for the water and oil to cool
before starting any work on the
machine.
MISCELLANEOUS
l Thoroughly wash the machine,
particularly the oiling and greas-
ing parts and the vicinity, thereof,
in order to prevent the ingress of
dust.
l Use genuine Komatsu replace-
ment parts specified in the parts
list.
l Use Komatsu specified oil and
grease. Use oil and grease having
the recommended viscosity for
the particular ambient
temperature.
l
Use clean oil and grease and
keep them in clean containers'to
avoid the ingress of dust.
l Inspect or replace oil in a dust-
free location to prevent the in-
gress of dirt.
l
Drain off used oil after heating it
to a suitable temperature (about
20 to 40°C).
