  If your LOBSTER Rivet Tools requires more triggers than usual to finish riveting, there might be a few reasons. First, ensure the rivet length matches the workpiece thickness.

Worn Jaws can also lead to this problem, so consider replacing them. Finally, insufficient hydraulic oil can result in a shorter stroke, so add more hydraulic oil if needed.

First, check that you're using the correct Nosepiece or Guide Tube for the rivet size and replace it if necessary. Ensure the Nosepiece or Frame Head ‘CJM’ is securely tightened with a spanner. An incorrectly assembled Jaw Case can also cause this, so verify its assembly. Clean the Jaws and the inside of the Jaw Case Head, and apply “LOBSTER” brand lubricant oil to the back of Jaws, if friction is the problem. If the Cylinder Cup is dirty, clean it and apply grease inside the cylinder and to the O-ring. If there's excess hydraulic oil, loosen the Bleed Plug to drain it. Lastly, check for and eliminate any mandrels clogging the Jaw Pusher or the G...
