UNAUTHORIZED MODIFICATIONS
If this machine is modified without permission from Komatsu, there is danger that problems may occur with safety
and that this may lead to serious personal injury. Modifications may have an adverse effect on items such as
machine strength and visibility. Before making any modifications, please consult your Komatsu distributor.
Komatsu cannot take any responsibility for accidents, failures, or damage caused by modifications not authorized
by Komatsu.
SAFETY AT JOBSITE
Before starting operations, thoroughly check the area for any unusual conditions that could be dangerous.
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 work site, 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 work site, contact each utility and iden-
tify their locations. Be careful not to sever or damage any of
these lines.
q
Take action to prevent unauthorized people from approach-
ing the job site.
When working on public roads, position flagmen and erect
barriers to ensure the safety of passing traffic and pedestri-
ans.
q
When traveling or operating in shallow water or on soft
ground, check the shape and condition of the bedrock, and
the depth and speed of flow of the water before starting
operations.
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.
