Here is a simple guide explaining how to use a locking clamp. The steps may vary slightly, depending on what type and model you are using.
Step 1 – Open jaws
Open the jaws of the clamp by pushing the lever away from the handle. This will pull the moveable jaw away from the fixed one, separating the two.
Step 2 – Place clamp
Place the jaws of the clamp on to the workpiece, with one jaw on either side.
Step 3 – Adjust pressure
Rotate the screw to the right in order to bring the jaws closer together and adjust the pressure. This will make sure the jaws have a secure grip on the workpiece.
Step 4 – Close jaws
Next, pull the lever back towards the handle. This will firmly close the jaws on the workpiece.
At this point you may want to use the screw to adjust the pressure once again, to make sure the correct amount is applied from the clamp.
Your workpiece is now secure within the jaws and the desired work can be carried out.
