This replacement main piston helps restore driving power and consistent stapling performance by transferring compressed air to the tool's driving mechanism. Built from durable metal for long-lasting reliability, it is an ideal solution for repairing staplers that are experiencing power loss, misfires, or inconsistent operation. Installation typically involves disassembling the cylinder assembly, replacing the worn piston, and reassembling the tool according to the manufacturer's service procedures. Regular lubrication and maintenance can help extend tool life and maintain peak performance.
Remove the top of the gun, remove the piston/driver. Remove the worn seals. Clean and lube the inside of the gun. Line up the hole in the driver and the hole in the piston, then with a punch drive the larger pin in first, then the small pin inside of the larger one. Install the piston and driver, and the new seals. Then replace the top.
