Checking your chain oiler

Chain oilers are a vital part of keeping your saw running well. No oil can even cause the chain to bind up. Over a period of time it can greatly increase the wear rate of your bar and chain reducing it's life. Chain oilers seldom go bad they just get clogged up with sawdust.

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.

Is your chain oiler working? If you're using saw a lot and the oiler isn't working properly the chain will get hot and bind up especially if the chain is too tight. Tighten the chain so that you can squeeze it in the center of the bar, with your second and third finger on the sides of your fingers (not a very strong grip) and you should be able to almost pull the chain out of the bar guide but not quite. Clean the oiler hole in your bar where the chain oiler injects oil into the bar. You can also run your saw without a bar and chain and see if the oiler is pushing oil out of the injector.

flymo 2200 chain oil leak when machine is running


That chainsaw should leak oil off the bar. A small amount of oil flipping off the chain is how it is suppose to work. If it is a large amount of oil dripping from near the sprocket then you probably need to do some cleaning.

I have 3 older Poulan chain saws, XXV, 1800, and 2000, essentially identical saws. They all use a check valve from the crankcase to pressurize the chain oil reservoir. The check valve apparently uses an elastormeric diaphram or ball as the check valve element, which over time turns to goo and the check valve fails open. No reservoir pressure, so no chain oil! Any experience with this dumb design problem? Thanks, Bernie


These oilers are called diaphragm oilers and work fairly well when the saw is new with great compression. As the saw wears out, the compression drops and a side effect is less oil pumped. The diaphragm is replaceable and it's not horribly expensive. Most good saws use a gear oiler - and even the newer Poulans use gear oilers. The gear oilers tend to have less problems and don't rely on engine compression.

I have a Poulan 20" chain saw that keeps leaking out the bar oil every time I put it in the container and store it. What causes this and can it be fixed by myself?


Most chainsaws have an adjustment for bar oiling and its quite normal for a chainsaw that is stored for long periods of time (weeks or even days) to leak out the bar oil. This is normal for chainsaws stored for several weeks or more.

Some of it may be reduced by adjusting the rate of flow for the bar oiler, read your manual carefully before attempting to adjust it. Adjust to too slow a flow rate will have adverse effects on performance and can lead to premature chain or bar failure.

Recommend that if you are going to store your chainsaw for more than a couple of weeks, drain the bar oil back out if it into a container (strain it through a paper towel before returning to your bar oil can). Also, you really should drain almost all the fuel and then run it until it shuts off if you are storing it for a month or more.
