Use extreme care when in areas such as these. Never exceed the lifting capacity of the machine.
• An operator must know the machine’s capabilities. When working on slones_ or near drop-offs be alert to avoid loose or sott conditions that could cause sudden tipping or loss of contrai. Be careful when the sprocket is under the cab; the direction of movement of the transpor! levers wili be opposite of direction of machine movement.
• Know the working range of the machine. Always check height, width and weight restrictions in the working area, and be sure the machine wili not exceed these limitations. Provida clearance for rear super-structure swing by barricading area to discourage entry. Use recommended buckets for machine, taking into account weight of material, loadability and heap/ng characteristics of material, terrain and other pertinent job factors.
