5. in the tapping force must be uniform, can one hand hold the wrench, one hand on the taps, uniform force rotation, or the two hands balance the wrench, evenly rotating;

6. the spanner should be suitable for the size of the tap. If the wrench is wrenches, it must not be lengthened on the spanner.

7. when the tapping is finished, when the taps are poured out, the wrench can not be retreated with the wrench after the wrench is loosened. This should be especially careful to prevent the thread and taps in the screw hole.
