Try taking the bar off the saw stand the tip ina container withenough gas or petrol to cover the sprocket leave it for half hourand see if youcan get it running free ,run it dry in forty years i dont ever remember greasing a sprocket and i`ve never had one seize up just try it see how it goes. if it is jamed up when you take it off and you are able to free it that way then the greas and oil are gathering the dust etc and causing it to jam

Bought new bar and chain for husqvarna 455 rancher today the first hour of cutting went well but now chain will not remain snug and the sprockt at end of bar isnt turning smoothly


Most are abel to be greased, wich helpes. Sounds like its it here not oiling right. When you start up place the nose of the bar near something dry and what to see a oil spaying of the bar . If that's ok,double check you aren't over tittering the chain.

The spocket at the end of the guide bar keeps on blocking up with bits of slinters of wood and it jams up after 3 or 4 cuts and it is all brand new can u help me please cheers chris


you shouldn't have a problem with chips stopping the nose sprocket. make sure the saw is oiling well and that if the nose is grease-able it is greased. If that's all OK then I would look at the nose sprocket itself and make sure it didn't get pinched

The chain on my Echo saw is moving very slowly to not at all


Your centrifugal clutch needs to be replaced or your chain guide (bar) is pinched.

My chain keeps getting loose....is that normal?


On a new chain perhaps. One that has been in service for a while the stretch should be adjusted out. Not holding the nose of the bar up as you tighten the bar nuts is the usual cause of this malady.
Chain Adjustment
  1. Make sure the chain brake is off (gloves recommended).
  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 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. HTH

I installed a new chain, adjusted tension, and saw will not cut.


Look closely at your chain, I'll wager it is the opposite direction.

The chain on my chainsaw is loose and even when I tighten the screw it doesn't seem to help. Someone told me that the chain stretches. Is that possible? How do I correct this problem?


New chains do stretch rapidly. If your chain has been run in for a while, the oiler is operating properly, and it is properly tensioned it should not require constant adjustment. A badly worn drive link can also be a factor.
It is very important to hold the nose of the bar up when tensioning and tightening the bar nuts. You may need to adapt the following to your saw, electrics sometimes are a little different.

If your adjuster is as far as it goes visit your local friendly chainsaw shop and have a link removed from your chain. HTH

How do you replace the old chain with a new one?


Wearing gloves is recommended. Loosen the bar slide it againt the clutch. Place the new chain over the clutch like pictured below. Place the drive links in the groove and work tour way right until the chain is over the bar nose. Grasp the nose and pull it right, the chain should rise toward the bar bottom. If necessary guide the drive into the bar groove. Find the chain tensioner and adjust it to fit the bar. Proceed as below.

Cannot get new chain on do i have to remove


Put it over the sprocket first, then work your way right putting it into the bar grove as you go, the nose last. Grasp and pull the bar right the chain should rise into grove, you may need to help. Loosen the chain tensioner some put the clutch cover on and tighten the bar nuts finger tight.
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.
  6. Continue holding the nose of the bar up & tighten up the side plate nuts / bolts / quick-release system.
