PRECAUTIONS FOR JOBSITE

INVESTIGATE AND CONFIRM JOBSITE CONDITIONS

On the jobsite, there are various hidden dangers that may lead to personal injury or death. Before starting
operations, always check the following to confirm that there is no danger on the jobsite.
When carrying out operations near combustible materials such as attatched roofs, dry leaves or dry grass, there
is a hazard of fire, so be careful when operating.
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.
If water lines, gas lines, or high-voltage electrical lines may be
buried under the worksite, contact each utility and identify their
locations. Be careful not to sever or damage any of these lines.
Take necessary measures to prevent any unauthorized person
from entering the operating area.
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.
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

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.
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.
