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 pictograms“ to indicate safety procedures.
Safety labels using pictogram
Safety pictograms use a picture to express a level of hazard-
ous condition equivalent to the signal word. These safety picto-
grams 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 condi-
tion at the top or left side, and the method of avoiding the haz-
ardous 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.

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.
