Using the DeWalt DWHT83192 clamp is a breeze. First, open the clamp wide using one hand. Then, place it around the objects you want to hold together and tighten it to apply the 300 - pound clamping force. If you need to use it as a spreader, just press the quick - change button. When using, make sure the objects are properly positioned to get the best clamping effect. Avoid over - tightening, as it may damage the clamp or the objects. For maintenance, keep the clamp clean after each use. Wipe off any dirt or debris with a dry cloth. If it gets wet, dry it thoroughly to prevent rusting. Also, check the removable jaw pads regularly and replace them if they are worn out. With proper use and care, this clamp will serve you well for a long time.
