Safety related information

Generally

1． In order to prevent the danger caused by unforeseen accidents and protect the staff and machinery, this machine is equipped with safety devices. However, the driver's staff should not only rely on these safety devices, but should also read the precautions described in this chapter and operate the machine on the basis of full understanding. Furthermore, do not think that the precautions described in the text are sufficient, and additional precautions should be considered according to conditions such as the environment.

2． In this manual, safety precautions called "DANGER", "WARNING" and "CAUTION" are described everywhere. In addition, this symbol is also used on the safety identification labels provided in this machine. These descriptions are distinguished by the following safety symbols. Please take precautions according to the description and drive safely.

 

3. This symbol is used for safety information and safety identification labels in locations where there is a high possibility of serious injury or death if the hazard cannot be avoided. This safety information contains precautions that must be taken to avoid hazards.

4． This symbol is used for safety information and safety identification labels in potential locations where a hazardous situation cannot be avoided that could result in serious injury or death. This safety information contains precautions that must be taken to avoid hazards.

Please be careful not to carry out driving operations, inspections, and maintenance other than those described in this manual, and be careful not to cause mechanical damage or personal accidents due to the responsibility of the staff.

In addition to the above-mentioned safety precautions, supplementary instructions to facilitate the work for the worker are displayed and described, which are separated from the explanatory text. These are special items that are useful to staff, so there is no safety identification label for this machine.
