Komatsu ecot3 WA430-6 Operation & Maintenance Manual page 213

OPERATION
When checking the tire inflation pressure, check also for small scratches or peeling of the tire, for nails or pieces of
metal which may cause punctures, and for any abnormal wear.
Clearing fallen stones and rocks from the operating area and maintaining the surface will extend the tire life and give
improved economy.
For operations on normal road surfaces, rock digging operations: High end of range in air pressure chart
Stockpile operations on soft ground: Average pressure in air pressure chart
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 suitable
deflection (see deflection ratio).

Stockpile operations mean the loading of sand and other loose
materials.
PRECAUTIONS FOR USING LOAD AND CARRY METHOD
When traveling continuously with load and carry operations, choose the correct tires to match the operating
conditions, or choose the operating conditions to match the tires. If this is not done, the tires will be damaged, so
contact your Komatsu distributor or tire dealer when selecting tires.
