WARNING:
Failure
to follow
these
safety
precautions
may lead to a serious accident.
7. PRECAUTIONS
DURING OPERATION
+
DO NOT HIT WORK EQUIPMENT
1
l
When working
in places where there are height limits, such as in tunnels,
under bridges, under electric
cables, or in garages,
be extremely
careful not to hit the boom or arm.
ENSURE GOOD VISIBILITY
l
When working in dark places, install working
lamps and head lamps, and set up lighting in the work area if
necessary.
l
Stop operations
if the visibility is poor, such as in mist, snow, or rain, and wait for the weather to improve to
a condition that allows the operation
to be carried out safely.

l
When working
on snow or icy roads, even a slight slope may cause the machine to slip to the side, so
always travel at low speed and avoid sudden starting, stopping,
or turning.
l
When there has been heavy snow, the road shoulder and objects placed beside the road are buried in the
snow and cannot be seen, so always carry out snow-clearing
operations
carefully.
+
WORKING
ON LOOSE GROUND
1
l
Avoid operating
your machine too close to the edge of cliffs, overhangs,
and deep ditches. If these areas
collapse,
your machine could fall or tip over and result in serious injury or death. Remember
that the soil
after heavy rain or blasting is weakened
in these areas.
l
Earth laid on the ground and the soil near ditches are loose. They can collapse underthe
weight or vibration
of your machine.
l
Install the HEAD GUARD (FOPS) if working
in areas where there is danger of falling rocks and dirt.
