SAFETY Keep Personnel Clear from Working Area If a person is present near the operating machine, the person may come into contact with the swinging front attachment or counterweight and/or may be crushed against an other object, resulting in serious injury or death. Before operating the machine, set up barriers to the sides and rear area of the bucket swing radius to prevent anyone from entering the work area. Make sure that no personnel other than the signal person or no obstacles are present in the working area before operating the machine. SA-667 Never Position Bucket Over Anyone Never lift, move, or swing bucket above anyone or a truck cab.

Serious injury or machine damage may result due to bucket load spill or due to collision with the bucket. Never allow the bucket to pass over anyone to avoid personal injury or death. SA-668 Avoid Undercutting In order to retreat from the edge of an excavation if the footing should collapse, always position the undercarriage perpendicular to the edge of the excavation with the travel motors at the rear. If the footing starts to collapse and if retreat is not possible, do not raise the front attachment in a panic. Lowering the front attachment may be safer in most cases. SA-1300 S-15
