OPERATION SECTION 1 Page 47 INFLATING TIRES Connect the air charm? hose to air DickuD (1) to inflate 1 For operations on normal road surfaces, rock digging operations High end of range in air pressure chart Stockpiie operations on soff 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 when carrying out load and carry operations When traveling continuously for load and carry operations, select tires to match the various ground conditions, or select ground conditions to match the tires. If this is not done, the tires will be damaged, so consult your distributor or tire suppliers. Deflection ratio (deflectfonIfree height) H. Free height h Height when loaded AS a guide for visual checks, the deflection ralio [deflection/free height) of the front tire should be as follows Normal loading and carrying operations (lift arm horizontal): approx. 15.25% Digging operations (rear wheels off ground):
approx. 25 35% 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 abnormal wear. Operating costs can be reduced and tire life increased by keeping the operating area in good condition and free from fallen rocks.
