1) blade may come loose and cause injury
2) saw may not cut properly
3) saw may overheat
4) saw may be difficult to handle

Answer 1

A circular saw without an upper blade guard is dangerous because the blade may come loose and cause injury. The blade guard is crucial for preventing accidental contact and ensuring safe operation.

Step-by-step explanation:

The reason one should never use a circular saw that does not have an upper blade guard is that the blade may come loose and cause injury. A blade guard is an essential safety feature that prevents accidental contact with the blade while it is spinning. Without this protective mechanism, the risk of lacerations or more severe injuries significantly increases if the blade dislodges or breaks, or if materials kick back while cutting.
