Sounds like the sprocket could be stripped. If so, then you would need to replace the sproket. I suggest you contact Master Parts at 800-466-1446 or online at www.masterparts.net. They may be able to help you.

remove side cover,using gloves slide the chain over the metal gears on the drive sproket.You may need to loosen adjustment screw to allow guide bar enough slack to reinstall chain

SOURCE: Chain keeps falling off bar afterwhen saw is

Reinstall the chain. Do NOT connect power. Mark one link (chalk, crayon, etc.) wear gloves and try to rotate the chain one complete revolution. Is this possible? No - remove the chain and remove burrs from the sides of the drive links with a flat file.

Yes - inspect the sprocket gear (KEY NO. - 11) pn 111363-01 new pn 122520-01 NLA, is it deeply grooved or perhaps worn through?

I'm going to get smacked as I have so many times before. The only thing RemingtonPower is producing today is unhappy customers. Replacement parts are exhausted. we aren't affiliated and had nothing to do with their decision to stop production.

Burrs on the chain or a defective sprocket are the most likely causes of your problem. If the gear is bad, there are no replacement parts available and I cannot help you further except to recommend you purchase a name brand replacement. Select a company you think will have replacement parts when you need them sometime in the future.

Chain adjustment

1. Make sure the chain brake is off (gloves will protest your fingers).
2. If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They don't need these really loose - finger tight will do.
3. Ease the tension adjustment until the chain is obviously loose.
4. Using one hand, hold the nose of the bar up.
5. While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more.
6. Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system.

First, inspect the chain for bent links or other damage. If ok, loosen the bar mounting nut(s) and turn the tension adjust screw CCW until the chain can be passed over the sprocket, then threaded over the far end of the bar. Make sure the chain cuts toward you on the bottom. Turn the adjusting screw CW until the chain begins to tighten. Proper adjustment is when the lower run of chain doesn't droop from the bar, yet allow easy movement of the chain by hand. Tighten the mounting nut(s) and recheck the chain adjustment. Pay attention to chain droop and readjust as needed during use of the saw. Make sure it is being properly oiled by running the saw in front of a piece of cardboard for several moments--it should throw off a thin line of oil. Hope this helps!
