OPERATION 12.13 WORK POSSIBLE USING WHEEL LOADER In addition to the following, it is possible to further increase the range of applications by using various attachments. 12.13.1 DIGGING OPERATIONS WITH ROCK PILES WARNING Always set the machine facing directly to the front when carrying out digging or scooping operations. Never carry out these operations with the machine articulated. NOTICE: If the tires slip, the life of the tire will be reduced, so avoid slipping or spinning the tires when operating the machine. When loading piled soil or blasted rock, drive the machine forward as follows to load. To prevent cutting of the tires caused by tires slipping, be careful of the following points.
! Always keep the jobsite flat, and remove any fallen rocks. ! When working with stockpiles, operate the machine in 1st or 2nd; when loading blasted rock operate in 1st. 1. When driving forward and lowering the bucket, stop the bucket about 30 cm (12 in) from the ground, then lower it slowly. REMARKS: If the bucket hits the ground, the front wheels will raise up, and the tires will slip. 2. Shift down immediately in front of the material to be loaded. When completing the shift down, depress the accelerator pedal at the same time and thrust the bucket into the load. 3.
When the material is in a stockpile, keep the cutting edge of the bucket horizontal; when loading blasted rock have the bucket tilted slightly down. Be careful not to get blasted rock under the bucket. This will make the front tires come off the ground and slip. Try to keep the load in the center of the bucket, the load will be unbalanced. 4. At the same time as thrusting the bucket into the material, raise the lift arm to prevent the bucket from going in too far. By raising the lift arm, ample traction will be produced by the front tires. 2-46
