33 OPERATION OF BUCKET SWIVEL (UNIT SWING) OPERATION 3 CAUTION To avoid personal injury: When working in groups, always let the others know what you are going to do before you do it. Keep away from the working area. To dig using the bucket, move the right attachment control lever from the neutral position left. Moving the control lever right, moves the bucket outwards and dumps its contents. IMPORTANT: Do not operate the left attachment control lever abruptly from right to left (or vice versa). Because of the law of inertia, this causes an impact load on the swing gear and the swing motor. Additionally, the life of the excavator will be shortened.
Unlock the swing lock pin before doing swivel operations. 1. Move the control lever to the left and the upper structure will turn to the left. 2. Move the control lever to the right and the upper structure will turn to the right.
