MACHINE OPERATIONS AND CONTROLS 3.3.6 SWINGING When operating the swing, check that the area around the machine is safe. 1. Operate left work equipment control lever (1) to swing the upper structure. 2. When not using the swing, set left work equipment control lever (1) to the N position. The swing holding brake will be applied. NOTE When using the swing on a slope, run the engine at low idling and operate the swing lever extremely slowly. Be particularly careful to avoid sudden movement when the bucket is loaded.
When the bucket is loaded and the left work equipment con- trol lever is operated, the swing holding brake is released, so the upper structure may swing momentarily, but this is not an abnormality. 115 WARNING
