lf your chain saw isn't lubing the chain it can cause serious chain ... How to Replace the Bar & Chain Oil ...
Take the bar and chain off, clean any sawdust and grime from where the bar meets the body of the chainsaw. Make sure the oil tank is full but don't reassemble yet. Start the chainsaw without the bar and watch to see if any oil is coming out of the little hole or slot above the bar bolts. Check that it isn't clogged with muck. If this bleeds oil then check the bar which has an oil hole that matches up with the oiler, this could be clogged. Blow out with compressed air, also run a piece of hacksaw blade around the groove where the chain sits in the bar to clear debris and blow out. Good luck.
Hi John... You will need to remove the bar and chain...behind the bar is the auto oiler it works on the shaft of the chainsaw, you will have to remove it and clean all the outlets for the oil to the chain.

Hello. Thin your bar oil just a wee bit with some kerosene. If you have a gallon of bar oil add 1/4 cup of kerosene, stir it up and you will be fine. For starters also, directly apply some bar oil to the chain so that you are always using a well lubed chain. Joe
Remove the housing that covers that bar and sprocket. There are two plates on each side of the bar that set over the studs.They may be identical or slightly different depending on the saw but at least one of them will have a hole in it for the oiler. If you remove the bar and both plates you will see the oiler hole on the saw housing. This oiler injects oil through the plate and into a small hole in the bar where the chain picks it up and carries it around the saw. If this hole becomes plugged with sawdust it will keep your saw from oiling the bar proplerly. This hole should be cleaned out periodically. It's not a bad idea to remove the whole chain periodically and clean the chain guide all the way around the bar and get any sawdust buildup out so the oil can flow better.
The chain oiler injects oil into the rear of the bar where the cover mounts over the sprocket. Take the bar off and clean out the oiler hole. There is usually some buildup of sawdust in the hole. Clean out the grove that the chain guide runs in all the way around the bar. You can see the injector nozzle under where that bar was when you removed it. Sometimes there is an ajusting screw there to increase oil flow.
There is probably a filter on the bottom of a hose within the oil tank. Go through the tank fill cap with a blunted rod. Move it slowly you should find the hose. Draw it gently toward the opening. You can probably find a new filter at a Husqvarna (parent company) dealer if you don't have a Jonsered dealer handy. Oil pump replacement is complicated. Any good chainsaw mechanic can replace it regardless of what saw they sell. Arboristsite dot com is a buch of chainsaw nuts (Eye r 1). They will give you better guidance. Please do a searh in the chainsaw forum before asking "how do I fix my saw", the answer has almost certainly been asked. Spike60 is a Jonsered dealer and is always helpful. HTH Lou
Remove the sprocket cover, bar, and chain. Find area where oil is discharged from case--is any part of the rubber seal damaged? Next, use compressed air to clean sawdust and dirt from oiler ports in rear of bar as well as the chain slot. Are you using motor oil instead of bar oil? Make sure there is nothing to prevent bar from making close contact with oiler port in case. Reassemble all parts and adjust chain tension.
