Question about Husqvarna Chain Saw 20" Bar

Husqvarnar model no 345 oil feed problem

The oil feed to the chain is not sufficient to lubricate the chain and bar. it has been in for repair several times and it is tested and said to be working yet the bar and chain overheat, even with a new chain fitted. a fine streak of oil is visible from the end of the bar when held close to a light surface but nothing compared to when it was new. there is no feed adjustment on this model and i have taken it apart and cleaned it so many times. this machine is useless, the only time i have been able to use it over the last year is when i had a friend manually oil the chain with with a can. dangerous, i know, on that occasion it worked fine. can you help me?

First thing check the feed hole through which the oil is delivered to the bar itself for debris,secondly the worm gear turning the pump shafft need only be slightly damaged to hamper full oil flow , next take the oil filler cap off, (with the bar ,chain ,bar plates, and oiler removed ) look where the oil pick up is in the case half and remove it and check for clogging and / or tears in the rubber hose,
if the cap is equipped with a breathing filler cap check make sure the cap breathes this will also hamper maximun oil flow capacity,
I stand by this , as I have dealt with product for close to 2 decades and know it intimately

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.

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.

What kind of oil or oil mixture do I need to use my Remington 2.0 HP 14" Electric Chain Saw?

Hi brown9148..
The only oil you need for your electric chain saw is "Bar and Chain" oil...specially formulated oil sold at Loews,HomeDepot,Ace Hardware, Auto parts stores,etc...
You use this oil to lubricate the chain and bar of your chainsaw when you are using it.
It will go into the oil tank and auto feed to the chain and bar...but keep a check on the oil level to make sure it is being used.
Refill tank when needed.
Please take time to rate me

I have a 345,after i adjust the chain,i use just a few minutes and the chain seems to get very tight and does not spin easily by hand

Check the sprocket to see if it has very deep groves wore into it.The chain might be getting in and out of the worn grove making it get tight.You also might not be getting enough oil to the chain.If the sprockets ok try cleaning the bar grove out with something like a small flat blade screw driver.There are small oil holes near the bar bolt holes.they need to be cleaned out every so offten.Blowing it out with compressed air helps .You should also flip the bar over every 2 to 3 hours of use.So it doesen't get wore bad on one side.Also try running the saw with the bar off to see if oil is coming out ok.If not your screen inside the oil tank might be plugged up.

Husqvarna 345 bar oiler

Remove the bar and chain. Start the engine and observe the oil delivery port in the side of the engine case. At a fairly fast speed, the oil should ooze out of the port. If little or nothing, check the pump, lines, and in-tank filter. If ok, clean the bar drive-end holes of sawdust and dirt, especially the small passages that go from the large holes out to the chain groove. Clean the entire groove and the outer end sprocket. Reassemble and test the oiling by running the bar tip at speed in front of a piece of cardboard--it should throw off a thin line of oil after several moments. Hope this helps!

Hello, Sir, Good Morning, I am operating POULAN chain Saw model no 4016.( i bought it in 2007 from germany) and facing a problum with oil system.which is not lubricating the bar and chain.i start engine...


Are you using the correct viscosity oil? - It is quite important that the oil is not too thick to freely flow. I am assuming that you are pushing down on the oil tank actuator cap to try and get the chain lubricated? (This is a manual process and does not lubricate the chain automatically on this saw)

Failing that, it sounds like there could be a blockage internally within the oil tank that needs to be cleared.

If this is the case, the user manual ( suggests contacting a repair centre.

You could always try removing the bar and chain and carefully working a small piece of wire into the lubricant holes to try and free any clogged up oil.

If this helps, please leave feedback - if not, let me know and I'll try and help some more!

Husqvarna 345 leaks (over uses)chain oil

An IPL (exploded parts list) for your saw can found here:
Serial number decode – for use with IPL
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit produced by Husky that week

The manual and IPL list no way to change oiler output. Your manual (page 16) says
"If the chain lubrication system is still not working after
carrying out the above checks and associated measures
you should contact your servicing dealer." HTH
One question - are you using bar oil? It is thicker and stickier than most oils.

Need to know what kind of oil to put in ryobi chainsaw

If it is an electric chainsaw (not gas powered) then the only oil you need is chainsaw bar oil, which lubricates the chain and bar during use (self feeding system). This goes into the chamber at the top of the saw. You can buy chain/bar oil for chainsaws at any good hardware store or outdoor power equipment store. You can use any brand of chain bar oil, most are pretty good.

If it is a gas/petrol operated model, I will need to know the model number to advise on that.

Where is the bar oil adjusted from on husqvarna 345

Turn the Hus 345 chain saw upside down, you may see a little Icon of a oil droplet and a + - arrow by the chain. THe adjustment screw is not pictured in any of the standard user manuals,. but it is a small black slot headed screw over a rectangale metal tab by the chain. I believe if you turn it counter-clockwise, it will give you more oil,, It did for me. If you have the bar off, you can start the saw and see it come out the hole, that would verify your oil pump is working. Make sure the holes on the bar are clean also. running the saw at a fast idle for 1 min should oil the chain well enouth that it starts spraying off the end of the bar when you gun the engine.
