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.
