1, understand the material needed to cut, if necessary to reduce the speed of rotation of the saw blade by reducing the pressure of the air.
2, ensure that the required cutting material is firmly fixed to prevent its movement.
3. When pneumatic air motor is operated, the stem is pressed with the finger, and then the cutting is started.
4, use the weight of the saw 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 completed, do not make the saw touch your body, the workpiece, or the other people in the vicinity. Pneumatic chain sawing motor power large)
5. When the air motor is closed, the stem is released.
6. The saw blade must remain moving before the next cutting begins. The saw blade can't contact any surface when a pneumatic saw.
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 sawing guide rod.
