Remove the cover, bar and chain and clean averything. Check the brake band to make sure it isn't broken. Put everything back together and check again. It sounds like worse case it is a worn sprocket or bar.

New Rancher 455. Ran for a few minutes then tried to tighten chain but adjuster was maxed out (completely tight clockwise). Removed cover, now can't get tension adjusting pin in hole in bar....pin sits...


Ok.. with the cover off the clutch you notice the screw and the pin that is suppose to go into the hole.. with the chain on the bar back the screw until the pin sits in the hole of the bar.. The chain should be lose you will see the chain dangle at the bottom of the bar.. put the cover back on with it lose.. hand tighten the two nuts that hold the cover on. with the bar in hand and you pulling the bar up make sure the two nuts are on tight enough so the bar does not move but dont over tighten it. tighten the screw you will notice the chain starting to move, and start to tighten up.. once the chain is in the grove of the bar grab the chain and move the chain with your hand to make sure you have not over tighten it. if the chain moves freely and is not lose ( you can also double check how tight it is by grabbing the chain below the bar and letting it go if it snaps back into the bar and doesnt hang there you are where you need to be.) tighten the two nuts up on the cover and start up the saw. Run the saw to make sure everything is all set and nothing is lose before cutting.. If the chain never get to tighten up you need a new chain. buy a new chain and follow the steps again. let me know if you have any questions

I have a 358351610 chain saw and need to find out how to remove the chain


Set the chain brake to off, then remove the fasteners on the right side cover where the chain drives from. This will release the bar which will slide back toward the engine and allow the chain to be removed. Note the direction of the cutting edge of the teeth. Clean everything including the two small oil passages that run from the large holes in the bar out to the chain groove on each edge of the bar. When refitting a new chain, back off on the chain adjustment screw (CCW) a few turns to allow the cover to fit to the bar properly. Fit the chain over the clutch sprocket, then insert the bar to the engine. Work the chain over the bar, then pull the bar outward to tighten the chain. Install the cover and the fasteners finger tight. Make sure the cover fits the bar properly. Tighten the chain adjuster CW so that the chain pulls up to the lower bar edge, but not so tight that you can't turn the chain by hand. Tighten the cover fasteners, then recheck the chain tension. The lower run of chain should be cutting as the chain moves toward the engine. Check the chain oiling by running the saw at speed with the bar tip near some cardboard--it should throw off a thin line of oil after several moments. Hope this helps!

Sounds like the chain oiling system is plugged or has failed. Remove the bar and chain--start the engine and see if oil oozes from the engine side port where the bar fits up to. If ok, then check the small oil passages that run from the large holes in the drive end of the bar out to the chain groove on each edge--they commonly get plugged with sawdust and dirt. If there are small thin plates located on either side of the bar at the drive end, make sure that the one with a slot which couples oil feed from the engine to the bar is installed next to the engine. When adjusting the chain, make sure you can turn it by hand when everything is tightened. Be sure to oil the chain manually before running it the first time. Run the engine at speed and hold the bar tip near some cardboard for a couple of moments--it should throw off a thin line of oil. Hope this helps!

NOT GETTING LUBE TO CHAIN


Remove the bar and chain. Clean the oil port in the engine side where the bar fits to. Start the engine and look for oil oozing out of the port. If ok, clean the bar drive-end oil passages that run from each large hole out to the chain groove on each side. Clean the entire chain groove, then reassemble the bar and chain. Tighten the chain until it pulls up to the lower bar edge, but not so tight that you can't turn the chain by hand. Recheck tension again after tightening the bar cover nut(s). Start the engine and run at speed for several moments with the bar tip near some cardboard--it should throw off a thin line of oil. Hope this helps!

Make sure the chain brake is released. Remove the two cover bolts completely and back off the chain adjustment screw several turns. All of this should release the cover. Make sure the chain teeth cut toward you on the bottom run. When adjusting the chain, leave the cover screws finger tight, and turn the adjusting screw CW to bring the chain up to the lower bar run, but not so tight that the chain cannot be moved by hand. Tighten the cover screws and recheck chain tension. When running, hold the bar tip near some cardboard while running at speed--it should throw off a thin line of oil onto the board. Hope this helps!

Tightening the chain


Fuel ratio is 40:1 using modern chain saw oil--not any petroleum base oil like boat motor oil. Be sure to premix fuel and oil in it's own container and to shake vigorously just before filling the saw each time. To remove the chain, loosen the chain adjustment screw several turns CCW, release the chain brake, and remove the side nuts that hold the rear chain cover. The cover will just pull off, then the bar can be pulled rearward somewhat and the chain worked off of the bar. Remove the bar by pulling it outward. Clean the entire area where the bar and chain fit to the engine, then clean the bar oil ports that run from the larger holes out to the chain groove on each side of the bar. Start the engine with bar/chain removed--oil should ooze out of the side port where the bar fits to. If ok, and the chain appears to be relatively unworn, refit everything in the reverse order of removal, making sure that the chain teeth cut toward you on the bottom run, and the chain adjustment tang drops into one of the large oil holes when replacing the cover. Tighten the mounting nuts only finger tight, and adjust the chain screw CW until the chain ceases to droop from the lower side of the bar, yet not so tight that it can't be turned by hand. Tighten the mounting nuts firmly and recheck the chain tension. If ok, and the engine runs well, start the machine and hold the bar tip near some cardboard while running at speed for several moments--it should throw off a thin line of oil onto the cardboard. Use common chain/bar oil available from home centers, hardware stores and saw dealers. Make sure the chain is properly file sharpened. Hope this helps!

Trouble with all three of my old Poulan Chainsaws. After starting and attempting to cut, chains either keep getting loose or very tight and stalls chainsaw. Would you think bent bar or dull chains?...


This may help.

You can have chains sharpened.
Just because you added oil does not mean it is getting to the bar. Your manual shoul explain how to test.
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 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

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.

How to replace chainpoulan pro 18"


First lay the new chain out with the cutter teeth facing forward on top. You should wear gloves because it takes very little to inflict a deep cut with these chains.

Take the tool that came with your saw and loosen the two nuts (don't take them off yet)that hold the sideplate on over the chain. Leave the saw setting on its bottom.

When the nuts are loose take the screwdriver end of your wrench (or a screwdriver) and loosen the chain quite a bit. Wearing the gloves, make sure when you pull it forward it moves very loose.

Now take the two sidecover nuts all the way off. You'll see how the chain goes arpound the sproket. Push the bar back toward the sproket until it is loose enough to remove the chain.

The bar will come off too, and it is important to note the small nub that goes in the tensioning hole on the bar near the bottom of the saw, fairly close to the sproket. Keep the chain straight; I hang mine on nails driven into the wall in my shop. You can get them kinked up so that they seem they'll never straighten out.

Take this time to clean all behind the sidecover itself, and the entire enclosed area. There will be sawdust, twigs, etc. I blow mine off with compressed air, but protect your eyes. Take something, toothpick, Qtip, or the like and clean the groove all the way around the bar, including the oil holes near the rear.

You should now be ready to insert the new chain, putting the bar with the slot lined up with the sidecover bolts, and gently get the chain on the sproket. This may take a couple tries before you get it right. When it is on (you'll see you have to hold the bar up or it will tip too much) hold the bar in place with the tightener in the hole, and slip the side cover back on. Tighten the nuts just enough to hold the bar in place, then tighten the chain tension screw, while holding the bar. Tighten the side nuts more, until the bar is held in place.

When it is just tight enough to hold the bar but not prevent the bar from moving forward when you tighten it, tighten until you can still move the chain, but there is no visible slack in the chain. You should be able to grab the chain at the bottom and with moderate force pull it away from the bar about a half inch.

I like to pour a little oil on a new chain so it has plenty of lube. The chain will stretch because it is new. Run the saw at about 1/3 throttle for a minute, holding the end close to something to make sure the chain is throwing off a fine thread of oil. Then run it at 1/2 speed about another minute. Rev it a few times, make a practice cut or two, and it should by now need another slight tightening.

Good luck!
