3.13 Machine Stability
Surface conditions
Pay attention to changing surface conditions while operating the
machine. Adjust speed and travel direction as necessary to maintain
safe operation.
• Machine stability and traction may be severely reduced when
operating on uneven or rough terrain, rocky soils, or wet or
loosely packed surface material.
• The machine may suddenly tip, sink, or fall when moved onto sur-
faces that have been newly filled with earth.
Steering angle
An articulated roller is more likely to tip when moving off an elevated
surface if the machine is turned away from the edge.
• As shown in the illustration on the right, always turn the machine
toward the edge when moving off an elevated surface.
Travel speed
A fast moving machine is more likely to tip or fall over while making
turns or changing direction.
• Reduce travel speed before turning the machine.
Drum overhang
The machine can tip suddenly if more than half of the drum width
extends beyond the edge of the elevated surface.
WARNING
Crushing hazards. Certain job site conditions or operating practices may adversely
affect machine stability.
