Questions people ask

What size chain does a Kobalt KCS 4040-06 take?

The Kobalt KCS 4040-06 with a 14" bar takes 3/8" LP pitch, .043" gauge chain with 52 drive links (Oregon R52).

What bar fits a Kobalt KCS 4040-06?

A bar with the A041 mount, in one of these lengths: 14".

Can I use a chain with the same length but different pitch?

No. Pitch and gauge have to match the bar and sprocket, and the drive link count has to match the bar. A chain that is off on any of the three will not fit or run safely.
