HANDLING THE TIRES * When checking the tire pressure, check also for small cracks and damage, and for wire or small pieces of metal which may cause punctures. Check also for abnor- mal wear. * Operating costs can be reduced and tire life increased by keeping the operating area in good condi- tion and free from fallen rocks. l For operations on normal road surfaces, rock digging operations: . . High end of range in air pressure chart l Stockpile operations on soft ground: . . . . . . . . Average pressure in air pressure chart l 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). 01 Inflation pressure (kg/cm’) Tire size Pb H Soft ground (pattern) rating (sandy ground) Normal road When shipped Free height Stockpile Digging.
