手鋸鋸削的注意事項

鋸條的松緊要合適，且鋸割時壓力不能太大，以防折斷傷人；

當鋸縫歪斜時，不可急于糾正，而需要慢慢地逐步糾正。

Notice of hand saw cutting

The tightness of the saw blade should be suitable, and the pressure should not be too large during sawing, so as to prevent breaking and hurting people.

When the SAW seam is skewed, it can not be corrected in a hurry, but it needs to be corrected gradually.
