HANDLING THE TIRES
a When traveling with standard
tires L-5 on a paved road surface,
use the table as a guide.
l
L-4 tires are suitable as tires for
driving on roads, so contact your
Komatsu distributor or tire dealer.
l Check the tire pressure before
starting, when the tire is cool.
l
When the machine is stopped,
check the tires and all other parts
for abnormalities, and check the
oil and coolant levels.
l Always travel with the bucket
empty.
l Never put calcium chloride or dry
ballast in the tires when traveling.
TIRE PRESSURE
Measure the tire pressure before
starting operations, when the tires
are cool.
If the inflation pressure is too
low, it causes overload on the tires;
if the inflation pressure is too high,
the tire may be cut or may burst
under shock. Therefore adjust the
inflation pressure to the values in
the following table.
Inflating tires
+r Stockpile operations mean the
loading of sand and other loose
materials.
f Deflection ratio = H H-h xl00
As a guide for visual checks, the
deflection ratio (deflection/free
height) of the front tire should be
as follows.
Normal loading and carrying
operations: approx. 10 - 15%
Digging
operations (rear
wheels off ground):
approx. 20 - 25%
Connect the air charge hose to
air pickup (I) to inflate the tires.
