Keep Person Clear From Working Area
 If a person is present near the operating machine, the
person may come in 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.
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.
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.
