When To Replace Your Ramset Cobra Piston SC301200A

ramset cobra piston SC301200AThe Ramset Cobra tool has become a staple for many of the trades including the low voltage and electrical trades.  The Ramset Cobra is what we call a Hilti DX-350 clone tool as is the Simpson PT27 and tools from other manufactures as well.  This is a well proven design that is easy to use and quite reliable.  One of the things I like is how stable it is when mounted on a ceiling extension pole tool, making it a great choice for ceiling grid wires for suspending not only ceilings but j hooks and light fixtures.  One of the most common wear parts on these tools is the piston, or drive pin.  How can you tell when it is time to replace the piston on your Ramset Cobra?  Murphy’s law dictates that what can go wrong will so even if you piston looks good, having a spare will save you down time.   When your piston is new, it has taper around the end.  Like a tent stake that expands when repeatedly pounded, the piston will start to flare over time.  This bevel accommodates this flare.  If you piston is starting to flare or chip, it is time to replace it, or at the least have one on hand.  As for the ring, typically they will last the life of the piston.  You can replace them but it isn’t easy.  To replace the piston on your Ramset Cobra, slide the annular spring to release the piston stop and slide out the barrel.  Remove the barrel clip and now the barrel halves will come apart.  Simply pull out the old piston and replace it.  Reassemble the tool in reverse order.  If you have any problems or questions, give a call toll free at 1-877-212-2377 and we will walk you through.    Find a complete line of Ramset Cobra parts here.
