Try replacing the oil

Posted on Apr 15, 2009

  • ricknags12 Nov 10, 2010

    I had the same problem today, I was running used motor oil in the bar oil.... Cleaned that out, decided to stick with bar oil.... As I was cleaning up the saw, I found a bar oil flow rate screw on the bottom of the saw. Turned it to the highest of its 3 settings, put new oil in it and it is now fine.

Chain saw motor is smoking


Hi Mark:
I'll go over the basics so please ignore what you already know.
Chain saws are 2 cycle which means the gas must have oil added. The ratio is 50:1 typically.
Chain saws are air cooled so they get HOT. They like to be kept clean, and a build up of oily sawdust is an invitation to an unwanted fire.
The chain is lubricated by a thick oil that gets put in a different tank. If you run out of chain oil, the chain will get really hot and you can actually ruin the bar by overheating it. A good rule is to always fill the chain oil tank (with chain oil) at the same time that you fill the fuel tank (with gas/oil mix)
Make sure the chain is kept SHARP. A blunt chain makes the saw work harder and causes friction which generates heat.
On a regular basis, take the bar off and clean the brake assembly and all the bits and crannies. Compressed air and solvent will make the job easy.
Chain tension should be kept snug but not too tight. I like to be able to lift the chain at the centre of the bar and have the underside just barely clear the groove in the bar.
Lots of bars have a roller at the tip and there is a fitting to inject grease. It's a good idea to use it regularly.
I think that about covers it. If you have any specific questions, send 'em on.

I have a Stihl MS 290, runs great, but the chain keeps tightening it's self on it's own


That's an unusual problem, usually the opposite happens. After making sure the chain brake is off, loosen the two nuts that hold the bar. Be sure to hold the bar up when adjusting the tensioner screw and adjust until the chain is just snug, but not too tight. While still holding the bar up, tighten the two nuts firmly. Check to see that the chain can move freely by hand. Then start the saw and run the chain at speed with something in front of the nose to check for adequate lubrication. You should note a slight fine spray of oil on the object in front of the nose of the bar. Inadequate lubrication, a chain that is binding on the bar, or an overly tight chain can cause the bar to heat up and expand, further tightening the chain. A properly adjusted Stihl saw will use almost all of the chain oil in the reservoir for every tank of gas. Too much oil is better than too little. The oil feed may have to be adjusted for operating in temperature extremes. If operating in very hot conditions, be sure that the saw has not run out of chain oil. The oil feeds faster when hot.

Leaking bar oil when hot


As the oil gets hotter it becomes more viscous, so if there is a leak it will get worse, remove the bar and chain, drain the oil from the oil tank and re fill with fuel, this will leak out very quickly and should show you where it is coming from, you can then address the problem.

Overheating the chain/bar is usually caused by insufficient oil getting to the chain, but can be caused by the chain being too tight to begin with (you should be able to turn the chain by hand), grit in the chain groove, or a poorly sharpened chain. The saw has an oil volume adjustment screw on the lower part of the case near the chain return area. Turning it CCW should increase oil flow. Oil volume can be judged by running the saw tip at speed near some cardboard for a moment--it should throw off a thin line of oil. Chain sharpening condition can be judged by the sawdust residue coming from the cut--if a powder-like material, the teeth are not sharp or are improperly filed. You should not have to bear down excessively on the saw to make it cut quickly. Hope some of this helps!

Can't seem to get my oiler to work properly. oil emerges when i run the saw with the bar removed, but chain is dry and hot when run put together.


Some saw manufactures design their oilers to only work with their bars. Are you running the mfg suggested or stock bar? Chain? Stihl Chain is designed to use 30% less oil because of oil groves cut into each drive link directed to the rivets. So if your running an aftermarket bar/chain, the oiling ports may not line up. Especially if it oils with no bar & chain

I have a poulan wild thing 18" bar and I have had a problem with the bars wearing out quickly. I use regular poulan bar and chain oil. Did this saw have a specific problem with the oiling system?


If the oil level in the chain oil tank goes down normally then you may be running the chain too tight. Also make sure the oil ports in the bar are clear so the oil can get to the chain. hope this helps you

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...


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.

Bar sprocket smokes, gets hot spot


Sounds like you're not getting enough oil to the chain. Basically you've got an oil pump, pickup and filter involved in getting oil from the resovior to the chain/bar. If you cleaned the obvious area and the chain is not coated with oil, you may have a clog further up (inside) the oil delivery mechanisms. Also, drain the oil from the tank, and see if you can "blow" air through there. With the saw running & pointed down, you should be able to see oil on the ground being slung off the chain, if not, you are not getting enough oil to the chain.
