The following signal words are used to inform you that there is a potentially hazardous situation that may lead to personal
injury or damage. In this manual and on machine labels, different signal words are used to express the potential level of
hazard.
Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury. This signal word is to be limited to most extreme situations.
Indicates a potentially hazardous situation which, if not avoided, could result in death or

•Safety labels
Safety labels are affixed to the machine to inform the operator or maintenance worker on the spot when carrying out
operation or maintenance of the machine that may involve hazard.
This machine uses "Safety labels using words" and "Safety labels using pictograms" to indicate safety procedures.
Example of safety label using words
Safety labels using pictogram
Safety pictograms use a picture to express a level of hazardous
condition equivalent to the signal word. These safety pictograms use
pictures in order to let the operator or maintenance worker
understand the level and type of hazardous condition at all times.
Safety pictograms show the type of hazardous condition at the top or
left side, and the method of avoiding the hazardous condition at the
bottom or right side. In addition, the type of hazardous condition is
displayed inside a triangle and the method of avoiding the hazardous
condition is shown inside a circle.
Komatsu cannot predict every circumstance that might involve a potential hazard in operation and maintenance.
Therefore, the safety messages in this manual and on the machine may not include all possible safety precautions.
If any procedures or actions not specifically recommended or allowed in this manual are used, it is your responsibility to
take the necessary steps to ensure safety.
In no event should you engage in prohibited uses or actions described in this manual.

time. Continuing improvements in the design of this machine can lead to changes in detail which may not be reflected in
this manual. Consult Komatsu or your Komatsu distributor for the latest available information of your machine or for
