The machine is always kept clean in the cutting machine. The oil filter is cleaned once a month. The hydraulic oil is set once a year. Before the work, the oil level in the machine must be checked. When the liquid level is lower than the specified level, the same brand name should be added. The hydraulic oil must not be mixed. When cutting materials, the workpiece should be placed in the center of the work area so that the cutting machine can be evenly distributed everywhere, thereby prolonging the service life of the cutting machine.
