SAFETY INFORMATION

ATTACHMENT COMBINATIONS

Depending on the type or combination of work equipment, there is a hazard that the work equipment may hit the
cab or other parts of the machine. Before using unfamiliar work equipment, check if there is any hazard of interfer-
ence, and operate with caution.

CAB WIDOW GLASSES

If the cab glass on the work equipment side is broken, there is a hazard that the work equipment may contact
the operator's body directly. Stop operation immediately and replace the glass.
If roof windows made of organic glass (polycarbonate) are damaged, they may crack and lose their protective
function. If the roof window has been damaged or cracked by falling stones or rocks, replace it with a new
part.

UNAUTHORIZED MODIFICATIONS

Any modification mode without authorization from Komatsu can create hazards. Before making a modification,
consult your Komatsu distributor.
Komatsu will not be responsible for any injuries, accidents, or product failures resulting from modifications
made without authorization from Komatsu.

SAFETY AT JOBSITE

Before starting operations, thoroughly check the area for any unusual conditions that could be dangerous.
When carrying out operations near combustable materials such as thatched 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 carry out operations at places 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 iden-
tify 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.
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

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.
