手锯锯削的注意事项

锯条的松紧要合适，且锯割时压力不能太大，以防折断伤人；

当锯缝歪斜时，不可急于纠正，而需要慢慢地逐步纠正。

清除冲压机床滑块底面、工作台面（或垫板平面）以及模具的上、下模座平面内的任何杂物或***。手工扳动冲压机床飞轮（或操纵点动按钮），调整上滑块到上死点位置，并转动调节螺杆，将连杆长度调到短（即闭合高度大）。

Remove any material or foreign object on the bottom of the stamping machine slide, working table (or pad plane), and the upper and lower die base of the mold. Manually pull the stamping machine flywheel (or point moving button), adjust the upper slider to the upper dead point, and rotate the adjusting screw, the length of the connecting rod to the shortest (i. e. the maximum height of the closed height).
