## 1.11 ENSURING VISIBILITY This machine is equipped with mirror and so on to ensure sufficient visibility, but there are areas where are outside the field of vision from the operator. Pay special attention to the invisible area and operate the machine. When traveling and working in poor visibility area, there is a possibility of injuries and accidents resulting in death because it is hard for operator to see the conditions of obstructions and the work area around the machine. Follow the followings when traveling and working in poor visibility area. - ・ When right visibility is poor due to attachment, raise the attachment to ensure visibility. - ・ Clean and adjust mirror at the pre-start inspection to ensure the visibility. - ・ When rearward visibility monitoring camera (option) is equipped with, clean the lens for clear vision. - ・ When the visibility can not be ensured sufficiently, provide a flagman in the working areas. Follow the instructions of flagman and pay attention to the signal. - ・ The signal shall be given by one flagman. - ・ When working in dark places, turn on the work light. And if required, provide additional lighting facilities to ensure good visibility. - ・ Stop working when it is impossible to ensure the visual field due to fog, snow or rain. <!-- image --> -Be sure to clean mirror before starting operation to ensure good visibility around machine. If the visibility around machine is not secured sufficiently, it may cause collisions and accidents resulting in injury and death. -To avoid the damage or break, do not install the mirror and so on to the handrail of cab entrance. If the mirror and so on is installed to the hand rail, the attaching part of handrail is stressed excessively. <!-- image --> -Do not attach the mirrors except the genuine mirrors (A, B, C and D). １
