SAFETY INFORMATION 1
To enable you to use this machine safely, safety precautions and labels are given in this manual and affixed to the
machine to give explanations of situations involving potential hazards and of the methods of avoiding such situa-
tions.
Signal words
The following signal words are used to inform you that there is a potential hazardous situation that may lead to per-
sonal injury or damage.
In this manual and on machine labels, the following 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 seri-
ous injury.
Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury.
Indicates a potentially hazardous situation which, if not avoided, may result in minor or mod-
erate injury. This word is used also to alert against unsafe practices that may cause prop-
erty damage.
Example of safety message using signal word
WARNING
When standing up from the operator's seat, always place the
lock lever in the LOCK position.
If you accidentally touch the control levers when they are not
locked, this may cause a serious injury or death.
Other signal words
In addition to the above, the following signal words are used to indicate precautions that should be followed to pro-
tect the machine or to give information that is useful to know.
This word is used for precautions that must be taken to avoid actions which could shorten
the life of the machine.
This word is used for information that is useful to know.

SAFETY INFORMATION FOREWORD

qSafety 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
know the level and type of hazardous condition at all times.
Safety pictograms show the type of hazardous condition at the
top or the left side, and the method to avoid hazardous condition
at the bottom or the right side. The type of hazardous condition is
also displayed inside a triangle.
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 precau-
tions.
If any procedures or actions not specifically recommended or allowed in this manual are used, it is your responsi-
bility to take the necessary steps to ensure safety.
In no event should you engage in prohibited uses or actions described in this manual.
The explanations, values, and illustrations in this manual were prepared based on the latest information available
at that 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 questions regarding information in this manual.
The numbers in circles in the illustrations correspond to the numbers in ( ) in the text. (For example: 1-> (1))
