Using these Bessey WS3 mitre clamps is a breeze. First, pick the workpiece you want to clamp. The clamps can automatically adjust to different sizes of workpieces, so you don't have to worry about fitting them. Then, use the spindle for quick - clamping. Just turn it until the clamp holds the workpiece firmly. Remember, these clamps are made for light clamping work, so don't use them for heavy - duty tasks. For maintenance, keep them clean after use. You can wipe them with a dry cloth. If they get a bit rusty, a light coating of oil can help protect them. Store them in a dry place to prevent damage.
