SAFETY
Operating Precautions
Watch out for hazardous working
conditions
¡Never undercut a high bank. Be
particularly alert for the possibility of a
cave-in.
¡Do not operate in places where there is a
danger of falling rocks.
¡Do not approach unstable surfaces (cliffs,
road shoulders, deep trenches, etc.). The
ground may give way under the machine’s
weight or vibrations, causing the machine
to tip over.
• The ground is weak after rain or
explosions.
• The ground is also unstable on banks
and near dugout trenches.
Travel in narrow or congested
places
To avoid contact accidents, pay attention to
the surroundings at narrow sites, indoors,
and congested places and operate at a
speed at which the machine can be safely
operated.
Precautions when passing
through tunnels or by high walls
Careless entry into tunnels or places with
high walls can lead to serious accidents such
as contact accidents, etc. Check height and
width limits in advance and verify that the
machine is within the limits.
Do not enter soft ground
Entry onto soft ground can result in the
machine tilting on its own weight, tipping over,
or falling in.
Do not enter weak ground such as that
following back-filling.
