How to Use Chainsaw Lubricating Oil
Chainsaw engines operate on a two-cycle system which is where the oil is mixed with the gas, as opposed to most engines that have separate gas and oil tanks. Chainsaws also have a chain oil reservoir to hold lubricating oil for the chain. The chain runs at such a high speed that it needs to be continuously oiled or it will seize up and break. Chainsaws of 40 years ago needed to have the chain oil manually pumped to the chain by way of a thumb operated injector. Today's saws have automatic oilers. Does this Spark an idea?

1
Unscrew the chainsaw's oil reservoir cap and let it hang by the chain attached to it.
-
2
Pour chainsaw bar oil into the reservoir. Use only bar oil designed for this purpose.
-
-
3
Screw the cap back on the reservoir. Don't cross thread the cap or the oil will leak out.
-
4
Start the chainsaw and rev the engine to make the bar oil flow to the chain.
-
5
Conduct a test to make sure the oil is reaching the chain by pointing the tip of the bar at a light colored object and revving the engine. If the oil is circulating properly splashes of oil will appear on the object.
-
6
Shut off the saw and check the bar oil regularly while operating to make sure the reservoir has not gone empty.

Tips & Warnings
The tank of fuel and the reservoir of bar oil generally last the same amount of time. Each time you refuel the saw top off the bar oil.
Keeping the saw chain sharp will make the saw engine run easier and use less bar oil.
Do not use motor oil or any other oil for lubricating the bar and chain. Use actual "Bar Oil" formulated for the job.
Many parts of modern chainsaws are plastic, including the fuel and reservoir caps. These plastic caps cross thread easily and allow the oil to leak out. Screw the cap in carefully.
Fill the bar oil reservoir only to the bottom of the screw threads in the reservoir. Do not overfill or the oil will leak out when the cap is tightened down .
