摘要： PROBLEM TO BE SOLVED: To improve operation ability during an overhead work, especially, when an overhead work is performed by one hand by using a portable band saw for cutting a cutting material such as a pipe material by stretching over and rotating a band saw between right and left part of saw wheels, because the cutting material is pressed to a lower guide member at an opening at which the band saw is exposed and work starts, and results in large load, therefore operation ability must be improved.SOLUTION: A front side of an opening 30 at which a band saw 13 is exposed is provided with a first guide member 31, and the first guide member 31 is hung on a cutting material W disposed above it and a cutting tool 1 is held in a hung state. Thereby, load applied to a right hand RH of a user H decreases, so operation ability of the cutting tool 1 is improved.
摘要翻译：要解决的问题：为了提高在高空作业中的操作能力，特别是当通过使用便携式带锯进行高架作业时，通过拉伸和旋转带锯之间的方式来切割诸如管材的切割材料，因为在带锯露出的开口处切割材料被压到下导向构件上并且工作开始，并且导致大的载荷，因此必须提高操作能力。解决方案：前部带状锯13露出的开口30的侧面设置有第一引导构件31，并且第一引导构件31悬挂在设置在其上方的切割材料W上，并且切割工具1保持在悬挂状态。因此，施加到使用者H的右手RH的负荷减小，从而提高了切削工具1的操作能力。
