How does a Poulan chainsaw bar and chain oiler work?

Question

My Poulan 245 Pro is not getting oil to the chain. Tried to clean but no luck. What mechanism forces the oil to lubricate the bar? Do you know the repair method? Thanks to all.

Answer 1

Most oilers work off either a gear pump or a pressure system on the tank. Depending on the age of your saw it may be worn out or simply dirty and clogged inside the tank.
You may have to clean and flush the tang and use a solvent to pump through the system.
Take the bar and chain off and set aside, start the saw and see if oil comes out the port that aligns with the bar..........

If this does not work then it is time for a trip to the Saw Shop.

Answer 2

The oil comes from the tank through a pump to the area of the bar. From there it goes through the bar to the groove. All of those areas need to be free of debris. The problem also could be the pump or the hoses from the tank to the pump. Any holes in the hoses will cause a non oiling problem. The saw being that new, I would clean it real good and see if that takes care of the problem. One other question, how do you know it isn't getting oil? It doesn't put out a lot of oil. It will put out almost no oil at idle and engough to keep the chain and bar lubed at high speed. Is the chain and bar getting hot? Your owner's manual should tell you how much oil it should use. Like fill the chain oil tank every other tank of gas. The bar plates could be installed incorrectly. One may have a hole or slot for oil and the other one doesn't. There are inner and outer plates. They go between the bar and drive case cover. There also may be a screen/filter on the end of the oil pickup hose in the oil tank. Fish the line out of the tank with a piece of wire and check the screen for debris. Don't run it if the chain isn't being oiled, it will ruin the chain and hte bar. I usually hold my saw close to a object like a cardboard box and run it full throttle for a bit to see if it is oiling. There will be a bit of oil on the cardboard. Not a lot like a spray but some.
