  錮金屬鋼合金超級鋸條，耐高溫、耐摩擦、使用壽命長。非常適用于鋸割不銹鋼、鎳基合金、鐵、銅、 鋁、玻璃、塑料、木材等。
 技術參數(shù)： 
 型號  FDJ-120 -220
功率  0.5kw 
耗氣量  0.6 
切割寬度（直徑）  120mm 
鋸片速度  60m/min
重量  6kg

 使用方法：
 1、了解所需切割的材料，如有必要可以通過降低空氣壓力來降低鋸片的轉動速度。 
 2、確保牢固固定了所需切割的材料，防止其移動。 
 3、氣動空氣馬達時，用手指按壓閥桿，然后開始切割。 
 4、用鋸的重量來控制切割壓力。對于較軟的材料來說，這樣的重量已經足夠。過多的壓力會降低鋸片的速度。對于較硬的材料，可以通過加壓的方式來降低鋸片的轉動速度。切割是保持鋸筆直。鋸片的任何扭曲或歪斜都可能降低其使用壽命。（注意：避開切割后可能掉落的碎片。切割即將完成時，切勿使鋸碰到您的身體、工件或附近的其它人員。） 
 5、關閉空氣馬達時，釋放閥桿。 
 6、下次切割開始前，鋸片必須保持運動狀態(tài)。氣動鋸時，鋸片不能接觸任何表面。 
 7、斷開空氣軟管時，關閉空氣軟管閥。斷開前，先打開空氣閥給軟管減壓。 
 8、更換鋸片前，務必斷開空氣軟管，并推動閥桿以釋放掉馬達內的壓力。 
 9、順時針轉動調整手柄以便釋放鋸片導桿上的張力。然后釋放側面板的鎖以便打開側面板。然后從驅動輪上取下鋸片并將其從鋸帶導桿上松開。Product introduction:

Use method:
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.
