Adjustment of Machine

The blade adjustment
The cutting stick can be used in both sides for four times.

When the cutting stick is badly worn, you need to adjust the side of cutting stick or change it.
Using ejector rob to push-out the cutting stick.(As shown in Picture 2)
After finished the replacement of knife, put the cutting stick into the groove from the front table.In that process the two ends of cutting stick should be put flat and then press cutting stick firmly into the groove.

Knife adjustment
Knife replacement (shown diagram 3)
When dismantling the knife (refer to diagram 4),turn off the power,first dismantle the second and sixth screw,insert the handle (diagram 3.1) into the second and sixth hole and screw down,then dismantle other screws,then rotate the handle (diagram 3.1) anticlockwise, take down the knife, please note: buttress the knife to prevent hurting operator.

Knife installation (shown in the diagram 4) Turn off the power,first wipe the grinded knife by the cloth, (if the knife edge is rolled up, please grind it by whetstone).Screw the handle into the second and sixth hole,then install the knife grinded well on the wood knife changer (provided by the factory), push the wood knife changer and the knife together to knife installation position in front of clamping bar, make sure that the hook hole of the knife is put onto the hook board, loosen the two handles on the knife, then rotate the wrench, insert the knife onto the knife bed and align with the screw hole, then install the screw and tighten. Take down the wood knife changer and wrench.
Note: Do not put your arms under knife bed and clamping bar.

Knife adjustment
Every time install the new knife, or old knife grinded, adjust the height of knife bed by manual in order to adjust the cutting depth of the knife. To avoid the new knife replaced causing accidents because of deep cut due to big height.
To determine the depth of cutting: Manually pull the knife locking handle(Picture 1,11),press the two hands cutting button,and stop the knife bed in the lowest position after one circle of cutting , Then observe if the cutting depth is piston rod normal(the normal cutting depth is about 0.5~1mm （0-1/64″~0-3/64″) . If the depth is not reasonable, bed height on the left side of the piston rod can be adjusted in the picture the edge of the sword;If the blade only touch the knife at one side,you can solve it by adjusting the hex screw of the knife eccentric shaft in front of the machine(Picture 1,4). When the blade wears about 12 to 15 mm(0-15/32″ to 0-19/32″), you should use the second row of screws hole in the blade. If the blade is worn and unusable after using the second row of screw hole , the blade should be changed. When changing the new blade, Put a new blade should be tuned the piston rod to the highest position.

Note 1: After adjusting the knife, the knife locking handle should be adjusted to the original position.
Note 2: when the blade wear, adjust the knife bed height (piston rod) first, and then the knife bed eccentric shaft, and finally the knife bed delay time in a computer.

Adjustment of paper impeller
The adjustment of the verticality between the paper push side and working table surface is achieved by adjusting the screw(3).Before adjusting, please little loosen the bolt M630(4) and screw M515(6), then rotate the screw clockwise to lift the end of paper impeller, the angle between the paper push side and working table surface reduces; anti-clockwise rotates,the angle expands.After adjustment, you should hold the screw first and fix the bolt M630(4) firmly, and then lock the two screws M515(6).
The back limit of paper impeller is controlled by limit switch,front limit is controlled by PLC.
