On the bottom of the saw there is an adjusting screw that allows oil to come out onto the bar. There is three different settings. Adjust the screw to a certain setting. Then start the saw, put a board in front of you, rev the saw up and you should start seeing vertical line made by the oil. If no line is present, adjust the screw to a higher setting and try again. If this does not fix the problem, the oil line is clogged and will need to be cleaned out. Hope this helps.

Dear Sirs, I don't have a manual to look this


There are two holes in the end of the Bar, the oil comes though them from behind the bar and goes into the channel (oil passages) that goes around the bar, clean the small oil passages in the drive end of the bar that run out to the chain groove on each edge from the large holes.

My chain saw is doing the same thing. I have only used it about 5 hours since owning it, and it worked great last time I used it (year ago). I think maybe my pump is not working. Did you ever get your's working ? I was told to take the bar off and Start the engine and observe whether oil oozes out of the side port. If no oil comes out, then the oil pump, oil line, or oil tank filter may require service.

Husqvarna 235 is not oiling.Hole and groove on bar have been cleaned. The saw does drip oil with the bar off when running.All parts are clean but bar is not getting oil.Hope you can help,thanks.


With saw running and high speed hold saw close to a piece of wood and check for oiling. If still no oil, then use air pressure at hole in bar to clear.

Husqvarna 350 oil not getting to chain


Take the bar and chain from the saw. Clean the two small ports that run from the large oil holes at the drive end of the bar out to the chain groove on each side. Clean the entire chain groove. Start the engine with these parts removed--oil should ooze out from the side port in the engine case with the engine running at med speed. If it doesn't, then there is trouble near the pump inside the case. When everything is back together, run the saw at full speed with the bar tip near a piece of cardboard--it should throw off a thin line of oil onto the cardboard after a few moments of running. Hope this helps!

Chainsaw quit cutting well, the bar gets half way down in a log and it quits cutting, the engine even starts to choke down


Remove the bar and chain--check the oil port in the side of the engine case where the bar fits up to. Start the engine--oil should ooze out of the port. If not, service the pump, lines and tank filter. If oil does ooze out, clean the chain groove, and the two oil passages that feed oil to the groove. If the outsides of the chain groove have flared out from chain wear, file these edges off (about 45 degrees) til they don't project beyond the bar vertical surface so that they don't catch on the kerf cut. Make sure the chain is being sharpened and adjusted properly. The 'choking down' may be from the engine overheating while trying make the cut. The engine should 4-stroke when running at speed, but immediately 2-stroke when cutting. Make sure the air cleaner and muffler are not plugged. Hope this helps!

Have cleaned bar grooves and holes, blown air through the oil line and my husqvarna oils but it just drips out instead of oiling the chain. When i take the chain and bar off oil comes from the hole but it...


The oil exiting the case next to the bar should just 'ooze' out depending on how fast the engine is running. Check the area around the oil port looking for an 'O' ring or other formed seal that may be damaged or missing. Make sure the small passage between the large hole (that lines up with the oil port) in the bar and the chain groove is open. It's easy to miss when cleaning. Make sure that the bar snugs up to the port firmly (otherwise, the oil just runs down the case). A check of oil delivery to the chain is to run full throttle for a moment or two--the end of the bar should paint a light line of oil on some paper or cardboard in front of the tip. Hope this helps!

455 rancher will not produce oil for the chain. Oil pump replacement? Need repair manual or parts breakdown. Thanks Warren


Also make sure that where the oil is pumped against the side of the bar that the oil port (little hole) that feeds oil into the bar's slot is clear. Mine would go through a tank of oil with each tank of gas, but the chain wasn't getting oiled until I cleaned out this little hole.

Piston ring compressing


Don't use a rubber mallet! It shouldn't take that much force! Make sure the piston ring is compressed enough so it will fit inside the cylinder as you slide it down over the piston. Be very delicate! It doesn't take much effort to break a piston ring or screw up the crank bearings. Just take your time and make sure everything is lined up and extremely clean.a thin coat of 2-stroke oil on the piston, rings, and inseide the cylinder will help protect everything - just make sure you're working in a clean environment where there's no dirt and grime for the thin coat of oil to attract.
