Using your Bessey ClassiX GSH lever clamp is a breeze. First, open the clamp by pressing the non - slip trigger. Place the object you want to clamp between the jaws. Then, release the trigger to apply the clamping force. It's that simple! When using the clamp, make sure the object is centered between the jaws to get the best clamping effect. Also, avoid over - tightening the clamp as it might damage the object. For maintenance, keep the clamp clean and dry. You can wipe it with a clean cloth after each use. If there's any dirt or debris, use a mild detergent to clean it, but remember to dry it thoroughly to prevent rust. Store the clamp in a cool, dry place when not in use.
