The Stihl 63PS3 Picco is a 14-inch replacement chain loop for compact top-handle and lightweight chainsaws. It has 50 drive links, a 3/8" low profile (3/8P) pitch and a .050" gauge. It replaces Stihl part number 3616 005 0050.
The chain uses chisel cutters and bumper drive links, which reduce kickback. It is meant for replacing worn or damaged chain loops.
To install, remove the old chain from the guide bar, then fit the new loop onto the sprocket and bar. Adjust the tension so the chain is snug but can still be moved by hand. Lubricate it with bar and chain oil and test the saw before cutting. Sharpen it regularly with a 4.0mm (5/32") file.
