Before the cotton pulp going through the cotton cutter, lose the trimming bolts on both sides of the cutter as well as the bolts in the center, and tighten the φ12 bolt a little to leave a certain distance between the upper roller and down roller. In case the pulp cannot be cut on one side, just loosen the pressure on the cut side and tighten the pressure on the uncut side in order to balance the rollers on both sides to make the pulp be broken easily through the cutter.
（4）Inside and outside adjustment:
Loose the four tighten bolts on the cutter adapter, turn the inside and outside adjusting knob by the adjustable spanner. The cutter body will move outward if the adjusting knob is turning clockwise, and move inward if turning counterclockwise. As for the X type cut rejects, if the outside edge is bigger than the inside edge, move outward of the cutter body. Otherwise, reverse it.
（5）Fore and aft adjustment
According to the indicated fore and aft direction of the brake, adjust the position of the cutter through the handwheel.
（6）Air volume adjustment
Turn the suction air piece when its tighten bolt is loosened. The air should be sucked immediately once the x type rejects of newly cut are emptied. Then tighten the bolts again. Adjust the distance between the aspiration channel and the cutter to make sure that the X type rejects can be sucked away smoothly.
4、Adjustment of Guide Way
（1）Pressure adjustment
When the requirement temperature achieves but the guideway is not pressurized, increase the pressure uniformly on both sides of the guide way. The procedures to adjust pressure are the same as what are applied to the cotton cutter. When both the temperature and pressure meet the requirement, check if the material is fed smoothly.
（2）Temperature adjustment
Adjust the temperature according to different materials. In case the pressure is enough while the guideway cannot be pressed up, heat the guide way step by step until it is pressed up.
When the guide way cannot be pressed up in spite of enough temperature and pressure, please check if there is any impurity or burr occurred on the guideway, and if there is some electric heating tube damaged.
When the machine is speeded up, increase both the pressure and the temperature accordingly.
（3）Inside and outside adjustment
Adjust the center distance of the guideway properly. The inward and outward adjustment procedures are the same as that of the cotton cutter.
