SAFETY INFORMATION FOREWORD q 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 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 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.

Continuing improvements in the design of this machine can lead to changes in detail which may not be reflected in this manual.
