How to use: 1, understand the material that needs to be cut, if it is necessary to reduce the rolling speed of the saw blade through the downward air pressure. 2, ensure sturdy and fixed the required cut data to avoid its movement. 3. When pneumatic air motor, press the stem with the finger, and begin to cut. 4, the cut pressure is controlled by the component of the saw. For softer data, such components are now satisfied. Too much pressure will reduce the speed of the saw blade. With more hard data, the rolling speed of the saw blade can be reduced by pressure. The incision is to stick to the saw vertical. Any twist or tilt of the saw may decrease its service life. (notice: avoid fragments that may fall after a cut. When the cut will be completed, do not make the saw touch your body, the workpiece, or the other people in the neighborhood. 5. When the air motor is closed, the stem is released. 6. Before the next opening, it is necessary to adhere to the movement of the saw blade. When a pneumatic saw, a saw can't touch any appearance. 7. When the air hose is disconnected, the air hose valve is closed. Before disconnecting, open the air valve and decompress the hose. 8. Before replacing the saw, be sure to disconnect the air hose and push the stem to release the pressure of Madane. 9, adjust the handle clockwise to release the tension on the sawing 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 guide rod of the saw
