1.Use 3T forklift fork to hold the hole in the bottom of the wedge-driving hammer;
2.Connect main pipe to the 0.4-0.6mpa compressed air source;
3.Forklift removes forward to wedge area, keep ram be close to the wedge large end, manipulate the manual valve to realize striking; In this time, main piston will impact deputy ram, thus it will pass impacting force to wedge through the cap, then the wedge will be tightened;
4.Ensure the distance between the ram and wedge is less than 80mm；When the distance is greater than this, the forklift needs to move forward to ensure that there is no empty striking;
5.Adjust opening size of throttle valve to control the opening size of main valve, and then control the impacting force.
6.Be sure to lubricate the piston with a manual oil pump before each work;
7.The gas source should be used by the oil and water separator to reduce the moisture in the compressed air in case the cylinder is corroded.
