Machine Stability
WARNING
Crushing hazards. Certain job site conditions or operating practices
may adversely affect machine stability.
 Follow the instructions below to reduce the risk of tipping or falling
incidents.
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 surfaces 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.
 Reduce travel speed and watch the drum position carefully when operating along the
edge of an elevated surface.
 Keep as much of the drum on the elevated surface as possible.
