PRECAUTIONS FOR OPERATION 2
PRECAUTIONS FOR JOBSITE 2
INVESTIGATE AND CONFIRM JOBSITE CONDITIONS
On the jobsite, there are various hidden dangers that may lead to personal injury or death. Before starting opera-
tions, always check the following to confirm that there is no danger on the jobsite.
q
When carrying out operations near combustible materials such as thatched roofs, dry leaves or dry grass,
there is a hazard of fire, so be careful when operating.
q
Check the terrain and condition of the ground at the worksite, and determine the safest method of operation.
Do not operate where there is a hazard of landslides or falling rocks.
q
If water lines, gas lines, or high-voltage electrical lines may
be buried under the worksite, contact each utility and iden-
tify their locations. Be careful not to sever or damage any
of these lines.
q
Take necessary measures to prevent any unauthorized
person from entering the operating area.
q
In particular, if you need to operate on a road, protect
pedestrian and cars by designating a person for worksite
traffic duty or by installing fences around the worksite.
q
When traveling or operating in water or on soft ground,
check the water depth, speed of the current, bedrock, and
shape of the ground beforehand and avoid any place that
will obstruct travel.
WORKING ON LOOSE GROUND
q
Avoid traveling or operating your machine too close to the edge of cliffs, overhangs, and deep ditches. The
ground may be weak in such areas. If the ground should collapse under the weight or vibration of the machine,
there is a hazard that the machine may fall or tip over. Remember that the soil after heavy rain or blasting or
after earthquakes is weak in these areas.
q
When working on embankments or near excavated ditches, there is a hazard that the weight and vibration of
the machine will cause the soil to collapse. Before starting operations, take steps to ensure that the ground is
safe and to prevent the machine from rolling over or falling.
DO NOT GO CLOSE TO HIGH-VOLTAGE CABLES
Do not travel or operate the machine near electric cables.
There is a hazard of electric shock, which may cause serious
personal injury or death. On jobsites where the machine may
go close to electric cables, always do as follows.
q
Before starting work near electric cables, inform the local
power company of the work to be performed, and ask them
to take the necessary action.
