Clearing fallen stones and rocks from the operating area and maintaining the surface will extend the tire life and
give improved economy.
q
For operations on normal road surfaces, rock digging operations: High end of range in air pressure chart
q
Stockpile operations on soft ground: Average pressure in air pressure chart
q
Operations on sand (operations not using much digging force): Low end of range in air pressure chart
If the deflection of the tire is excessive, raise the inflation pressure within the limits given in the table to give a suit-
able deflection (see deflection ratio).
Stockpile operations mean the loading of sand and other loose materials.
PRECAUTIONS FOR USING LOAD AND CARRY METHOD 3
When traveling continuously with load and carry operations, choose the correct tires to match the operating condi-
tions, or choose the operating conditions to match the tires. If this is not done, the tires will be damaged, so con-
tact your Komatsu distributor or tire dealer when selecting tires.
