4.8.4.a
CHECKING THE TYRE PRESSURE
WARNING
q
Inflate the tyres standing beside the outer belt.
q
Do not exceed the pressures recommended in the "TE-
CHNICAL CHARACTERISTICS".
This check is indispensable for the preservation, exploitment
and duration of the tyres.
The pressure must be as indicated in the specifications (see
"5.1.3 TECHNICAL CHARACTERISTICS").
While checking the tyre pressure, check also the conditions of
the tread and sidewalls.
4.8.4.b
CHECKING THE COOLANT LEVEL IN
THE RADIATOR
WARNING
q
Carry out this check with the machine parked on a level
surface and the equipment resting on the ground.
q
Do not remove the radiator cap when the fluid is hot,
since it may be sprayed out violently and cause burns.
q
Loosen the cap slowly in order to release the pressure
before removing it.
The radiator cap can be reached after raising the engine hood
(see "3.5.1 ENGINE HOOD").
Remove the cap (1) and make sure that the fluid level reaches
the filling hole.
IMPORTANT
q
If the fluid level in the radiator is low and the expansion
tank is full of coolant, check the tightness of the radiator
and make sure that there is no air leakage from the radi-
ator-expansion tank coupling.
If this inconvenience occurs repeatedly, contact your
Komatsu Dealer.
