Key points for installation, cooling, and maintenance

Before installing the GND handle, clean the blade holder, bolts, and bolt holes to remove burrs. The blade slides parallel to avoid tilting. The handle should be perpendicular to the workpiece and the overhang should be as short as possible. Lock the center height after adjustment. The internal cooling knife handle should be correctly connected to the coolant pipeline, with sealed joints to avoid leakage. For non hose cooling supply, liquid can be supplied directly from the tool holder connection point. Recommend using filtered coolant to prevent oil hole blockage. Regularly check the wear and clamping force of the blade holder, and replace the handle or clamping components if necessary.
