HANDLING THE TIRES a When traveling with standard 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. +r Stockpile operations mean the loading of sand and other loose materials. 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.
f Deflection ratio = H H-h xl00 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. 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% l Always travel with the bucket empty. Inflating tires l Never put calcium chloride or dry ballast in the tires when traveling. Connect the air charge hose to air pickup (I) to inflate the tires. - 57 -
