2 Check if there is excessive clearance between the upper and lower blades. If any difference is found, adjust it to about 0.2 mm.
3 Check whether there is a short adjustment of the delay disconnection time and relay time. If there is any difference, it should be set to 0.2~0.4 seconds.
4 Check whether the strength of the bar to be cut is too high. The user can cut the bar previously cut off and cut it again on the machine so that the strength of the bar to be cut can be more than 750N.
