Remove the bar and chain assembly. You may have to remove the sawdust from the oil hole to find it but it will be opposite the hole in the bar ahead of the drive sprocket on the top half of the bar. Usually when you remove the bar and chain the hole can be identified by the oily sawdust in the area that I just mentioned.

Thanks for using FixYa and for the great rating.

My Stihl MS 231 is not feeding oil to the chain how do I locate the problem and repair.

The chain and bar oil should feed from the reservoir to a small hole in the bar that feeds the oil to the bottom of the chain. If that little hole gets dirt in it, the oil won't feed to the chain. To clear the problem, remove the bar, remove the chain from the bar, and clear the hole in the bar and track for the chain in the bar. I've done this while out in the woods by just using a stiff dry piece of grass to push the dirt out. Once clear, replace the chain, teeth facing the correct way, and the replace the bar, and tighten.

How do i clean oiler for chain on stihl farm boss?

The filter could be stuffed with sawdust, but depending on the model of saw, the problem could also be the oil pump drive system.
First of all though, empty out the chain oil and then part fill the chain oil tank with petrol, replace the cap and with the saw switched off, shake the saw violently for 10 secs. Remove the cap and empty out the tank and then refill with chain oil and try out the saw, revving it and check if any oil is flowing onto the chain.
If that has not solved the problem, let me know what the model of the saw is, Farm Boss is not enough, it could be an 038 an 041 and a few more as the farm boss name is used as well as the number.
We can then check a few other points which could be causing the problem.

How to replace chainsaw chain

The bar is usually clamped with two hex nuts, you usually need to remove them, this allows the chain cover to come away, then wind back the tension adjusting screw ( with a flat blade screwdriver on a Husqvana other brands may be different ) back until the chain is loose enough to come off, the bar will also come off at this point.
It is a good opportunity to give everything a good clean at this stage and make sure the oil ways to the bar are clean and not blocked with wood dust, check the nose wheel on the bar spins freely and maybe grease it.
Put the new chain over the drive pulley the same way as the old chain came off, line it up in the bar slot and if you have the tension adjust wound back far enough for a new chain the bar will just flop over the two clamp bolts, replace the cover, and just do the nuts up finger tight so the tension adjust can be wound up to take the slack out of the chain.... not too tight ! it should still spin by hand without too much friction and you should be able to lift a link up half way out of the slot in the middle of the bar with your fingers.
Check the oil is getting to the chain by running at full speed with the end of the bar held just above a flat piece of clean wood, it should throw off a faint line of oil from the chain onto the wood.
Keep your chain sharp...
Happy sawing !

My Poulan Pro chain saw (model # PP4620 AVHD) doesot move B&C oil from the oil reservoir to the chain. How can I repair this?

is the area where you tighten up the chain clean there are a few holes in the bar that allow the oil to drip on to the chain if its been used for a while the holes could be clogged take off the bar and chain and clean with a small flat head screwdriver the groove that the chain rides in there should be a hole that goes all the way through make sure you wipe away any wood chipsthen run it and see if it throws out any oil

Have an 029 farm boss with 16 inch bar upgraded to 20 inch all was checked and bought from a stihl dealer they even put it on. went home used it for about 15 min and the bar and chain went dry no oil going...

It sounds like you may have something stuck in the oiler port or groove of the bar. You can use the pointy end of the chain file guide to clean the bar out and give it a shot again.
Good luck

I have a Poulan model #358-356-332 chain saw. I think that it is about 10 years old. The bar tip appears to be too shallow for the chain depth. You see daylight between the chain and the tip. We have...

I think you have more than one problem.
1. I think the pitch of the bar and the chain you are using are different.
2. I think either you failed to bar add oil to the bar oil reservoir or your oiler is not working. Why you are burning up bars.
3. I think your Poulan saw says Craftsman (model will not cross).

See page 14 for how to check oiler operation.

Oil System Plugged.
  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), if equipped with a sprocket nose ensure it rotates easily at least one complete revolution. 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 (oozes down side of saw). If yes reassemble your saw. If no, continue with 2.
  2. Work your way through the linkage (use IPL to identify components and locations) cleaning and replacing any defective parts as you go. Carefully check the hoses for cracks especially at bends and connections. If equipped with an oil pump it is usually behind the clutch (clutch is a left handed thread). Please make extensive notes & some digital pictures will help during reassembly.
If it does not oil on completion of 1 it is most likely a bad oiler or worm gear (see IPL).

Test as I suggest then post back (below) with what you find and we will continue. I will need clarification on the make and model of this saw to be much more help. If all else fails for the model provide the engine size in CCs. We are prohibited from contacting you directly. Sorry. HTH

How to adjust chain bar oiler

The Stihl 026 PRO does have an adjustable oiler and it is located on the bottom of the saw just below the clutch drum.
Stihl also builds an 026 "Standard" without the adjustable oiler, however, the hole location for adjustment is still there.

The 026 PRO will also have a decompression valve on top of the saw to make the rope easier to pull during startup. If you have the DECO valve you should also have the adjustable oiler. Hope this helps.

Loss of power

Don't continue to try for high speed operation until the problem is rectified. Look for loss of chain oil or the chain is too tight. If it is equipped with a chain brake, make sure that it isn't dragging on the clutch rim. (It would be very hot or blue colored.) If no oil, remove the bar and chain--run the engine and watch for oil coming out of a port near the sprocket end. If it does so, clean the holes in the drive end of the bar, especially the small holes that connect to the chain track slot. Adjust the bar to tighten the chain enough that the chain doesn't begin to droop from the bar, yet turn freely by hand. If no oil comes out of the port, then the oil lines or the oil pump are/is faulty. Be sure to use bar oil only in the tank?

Oil in container but not on chain

tube is clogged that lets oil get to chain. Find the hole exit to the chain and clean with pick of some sort. I have a set of picks various sizes kind of like a allen wrench set that I use. A long needle or tooth pick will work. The hole is cloged with wood chips either from the outside or accidently dropping in the oiling resivior when adding oil.
