Overview
Bundled as 2 chains, this chain is a direct replacement for Remington RM4618 RM4620 models. A worn chain strains the motor and increases kickback risk, so timely replacement keeps your saw running safely and efficiently.

Compatibility
This chain is designed to fit Remington RM4618 RM4620. Double-check your model number against the listing to ensure a correct match before installation.
Installation notes
Begin by shutting off the saw and disconnecting the power source. Loosen the bar-mounting fasteners and remove the side cover to access the chain. Slide the worn chain off, seat the replacement around the sprocket and into the bar groove with cutters pointing in the direction of rotation. Tighten the tensioning screw until there is slight play but no droop, then secure the cover.
Common questions
Q: Will this 2-pack 20 inch chainsaw chain fit both the Remington RM4618 and RM4620, or is it only for one model?
Yes, this chain set is made for the Remington RM4618 and RM4620 with a 20-inch bar. If your saw still has the stock 20-inch setup, these replacement chains should fit properly, but it’s always smart to confirm your current chain specs before installing.
Q: Do I need to do anything special when installing one of these 20 inch chains on my RM4620?
Make sure the cutter teeth are facing forward on the top side of the bar before you tension the chain. After installation, adjust the chain so it sits snug against the bar but can still be pulled around by hand, then recheck tension again after the first few minutes of cutting.
Q: How often should I sharpen or replace these chains on a Remington RM4618?
That depends on what you’re cutting and whether the chain contacts dirt or debris, but you should sharpen it anytime it starts pulling to one side or making fine sawdust instead of chips. Replace the chain when the cutters are too worn to sharpen effectively or if you notice damaged drive links, cracked cutters, or repeated stretching.
