 技术参数： 
 型号  FDJ-120 -220
功率  0.5kw 
耗气量  0.6 
切割宽度（直径）  120mm 
锯片速度  60m/min
重量  6kg

 使用方法：
 1、了解所需切割的材料，如有必要可以通过降低空气压力来降低锯片的转动速度。 
 2、确保牢固固定了所需切割的材料，防止其移动。 
 3、气动空气马达时，用手指按压阀杆，然后开始切割。 
 4、用锯的重量来控制切割压力。对于较软的材料来说，这样的重量已经足够。过多的压力会降低锯片的速度。对于较硬的材料，可以通过加压的方式来降低锯片的转动速度。切割是保持锯笔直。锯片的任何扭曲或歪斜都可能降低其使用寿命。（注意：避开切割后可能掉落的碎片。切割即将完成时，切勿使锯碰到您的身体、工件或附近的其它人员。） 
 5、关闭空气马达时，释放阀杆。 
 6、下次切割开始前，锯片必须保持运动状态。气动锯时，锯片不能接触任何表面。 
 7、断开空气软管时，关闭空气软管阀。断开前，先打开空气阀给软管减压。 
 8、更换锯片前，务必断开空气软管，并推动阀杆以释放掉马达内的压力。 
 9、顺时针转动调整手柄以便释放锯片导杆上的张力。然后释放侧面板的锁以便打开侧面板。然后从驱动轮上取下锯片并将其从锯带导杆上松开。Product introduction:

Use b:
1, understanding required cutting material, can reduce the rotation speed of the saw blade by reducing air pressure if necessary.  
2, to ensure firmly fixed required cutting material, to prevent the mobile.  
3, pneumatic air motor, pressed his fingers and began cutting stem.  
4, saw the weight to control the cutting pressure. This weight is enough for softer materials. Too much pressure can reduce the speed of the saw blade. For harder materials, the speed of rotation of the saw blade can be reduced by pressure. The cutting is to keep the saws straight. Any twist or skew of the sawblade may reduce its service life. (notice: avoid debris that may fall after cutting. When the cutting is about to be finished, do not make the saw touch your body, the workpiece, or the other people in the vicinity.  
5, close the air motor, release valve.  
6, before the start of the next cut, the blade must keep moving. The saw blade can't contact any surface when a pneumatic saw.  
7, disconnect the air hose, air hose valve closed. Before disconnecting, open the air valve and decompress the hose.  
8, replacing the saw blade, be sure to disconnect the air hose, and push to release the pressure on Madane stem.  
9, clockwise adjust the handle to release the tension on the saw blade guide rod.  Then release the lock of the side panel so as to open the side panel. Then remove the blade from the drive wheel and release it from the sawing guide rod.
