. OPERATION OPERATION 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. 3 - 154 When checking the tire i nflation pressur e, check also for small scratches or peeling of the ti re, for nails or p ieces of metal which may cause punctures, and for any abnorma l wear.
Clearing f allen stones an d rocks from th e operating area and maintaining t he surface will ext end the tire life and give improved economy. For operations on normal road surfaces, rock digging operations: High end of range in a ir pressure cha Stockpile operations on soft ground: Average pressur e in air pressure char Operations on sand (operations not using much digging force): Low en d of range in air If the deflection of the tire is excessive, raise the i nflation p ressure within th e limits given in th e table to give a suitable deflection (see deflectio n ratio).
