Chainsaw Chain Installation Directionality and Burr Removal/Repair

Chain Repair
Remove the bar & chain. Affix a piece of tape to or mark one of the upper chain links. Wear gloves, hold the bar parallel with the ground, the nose right, the tail left and the chain in the upper bar groove. Try to slowly rotate the chain CCW one complete revolution. If you cannot, it occasionally rides up and out of the bar groove or it catches there are likely burrs on the drive links.
I find it easiest to remove them by positioning the chain as displayed immediately below, so a file may be used on the exterior of the loop.



Chain Installation & Adjustment
The chainsaw chain links, on the upper part of the bar, must be installed as illustrated immediately above.

  1. Make sure the chain brake is off (wear gloves to protect 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 do not 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 center of the bar, if the bar has a sprocket nose, add a touch more (1/8 or less).
  6. Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system.

just bought and started using Ryobi chainsaw RCS2040 chain came off. while in use after putting the chain back in place the sprocket is not rotating thus not rotating the saw it seems as if it is locking. can you advise us how to free it?


You must loosen the bar a tad. There is a nut on the side which will loosen the bar. Look for an adjuster screw near by. You should be able to move the chain by hand, snug but not tight.

WITH THE SAW OFF OF COURSE!!!!!!! Wear gloves to prevent injury.

Did you get a manual with your new saw? Of course you did. Please review the manual cover to cover before you continue to use this MOST DANGEROUS TOOL in most households. Few other tools are found in the home that will do as much damage as quickly as a chain saw.

Chain came off and won't go back on


You need to loosen the bar first. (nut or nugs on the side ... shuld be a screw adjuster that runs parallel to the bar - the bar is the part the chain rides on) Did you do that? Put the chain back on then gently tighten the chain again. Should be a little play in the chain. Wear gloves to prevent injury.

The chain locked up with the engine running. noticed no oil in the oil chamber. what needs to be done?


The bar and chain got very hot. Try this:
  1. Remove the clutch cover, bar, and chain, clean the bar groove, any holes and passages on the rear of the bar (both sides, consider rotating the bar) Clean the saw oiler hole and channel. Insert a blunted, hooked piece of wire through the oil filler hole and pull the hose in the oil tank out. Pay attention to the screen or filter on the free end (clean or replace, difficult to determine serviceability). Start the saw and see if it oils when revved up.
  2. PUT ON GLOVES; completely remove the chain from the bar. Hold the bar horizontal and install the chain in the upper bar groove, (mark one of links) rotate the chain one complete revolution. If it rotates freely without catching or riding up in the groove you can reassemble your saw try it.
If my saw I would seriously consider replacing the bar and chain but I cannot see what damage has been done. HTH

Hold the nose up!

The chain keeps jumping off of my saw when I start it up. I've tried many times to keep the tension on and when I start it up, it jumps off again. What am I doing wrong? I followed the manual and it still does the same thing.


With the saw not running rotate the chain by hand (gloves encouraged). You may have a burr on a drive link or some links that can't rotate. When they meet the sprocket or nose the chain jumps.
You might try a new chain.
If you extend the drive links beyond the cutting side a flat file can be used to remove burrs from the drive links,

Chain adjustment
  1. Make sure the chain brake is off (gloves will protest your fingers).
  2. If necessary, loosen the nuts that are clamping the guide bar in place (or whatever your saw uses to hold the side plate and bar on with). We don't need these really loose - just finger tight will do.
  3. Ease the tension until the chain is obviously loose.
  4. Using one hand, hold the nose of the bar up.
  5. Now, while holding the nose up, adjust the tension so that the chain just touches the underside of the bar. Then tighten slightly more (1/8 turn on screw).
  6. Continue holding the nose of the bar up & tighten up the side plate nuts / bolts / quick-release system.
