Planer is a kind of automatic feeding, high production efficiency of woodworking machinery, mainly for the plane has been planed two reference plate or square, and then processing the opposite surface, making it a net thickness and width of the net. To ensure safety, the operation should pay attention to the following points: 1, Before operation, should carefully check the various parts of the machinery and safety guards are good, and then carefully adjust the machine according to the required size of wood and the scale of the machine tool. After adjusting the appropriate test run 1 to 3 minutes until the speed is normal, before feeding, each time the depth of the knife does not exceed 2mm. 2, the operation, the two should cooperate well, one person feed, one person pick up. To stand on the planer left or right side or later, to prevent the workpiece from flying wounding. When feeding, do not put your finger under the workpiece. The receiving worker should wait for the workpiece to leave the discharging roller after the material is connected, and should not be hard to pull. When feeding, the hand should be away from the drum. 3, in planing, in case of wood does not move, safety rods can be used to promote; if invalid, should stop the feed roller, and then stop axis, to be stopped after the steady down the table, remove the workpiece to troubleshoot. 4, the thickness difference of more than 2mm above several workpieces are not allowed to planing at the same time, to prevent thinner parts because of the pressure is not tight and rebound wounding.
