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.
¡ Keep machine well back from the edge of
an excavation. Avoid undercutting the
machine.
¡ 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.
Operating on slopes is
dangerous
When operating on slopes or grades, slewing
(swinging) or operating working equipment
may cause the machine to lose stability and
tip over. Avoid operating on slopes whenever
possible.
¡ Level off the work area.
¡ Avoid swinging the loaded bucket in a
downhill direction. This will reduce the
stability of the machine.
