All gas-powered chainsaws need gas mixed with oil in order to work correctly. Mixed gas refers to combining the gas that some chainsaws use with oil. Only the gas-operated chainsaws take mixed gas, because they are the only ones actually running on gas.
A chainsaw uses regular unleaded gas but it needs to be mixed with the right oil. Chainsaws that take regular gasoline can also be started on a mixture of gas and oil but require more preparation before use. Mixed gas varies in ratios because each chainsaw has its specifications that you need to look at for you to figure out how much pre-mix oil and gasoline you should be using for your saw.
does a chainsaw chain stretch Related Question:
How much will a chainsaw chain stretch?
How much will a Chainsaw Chain Stretch? Chainsaw chains stretch considerably after their first run, with about 1/100 of an inch per link. A longer chain with 75 links stretches around 0.75 inch. A shorter chain will still stretch almost half an inch.
Does the chain on a chainsaw need to be tight?
A properly-tensioned chainsaw chain should still be just a little loose on the chainsaw guide bar, but the chain needs to be tight enough that you can’t pull the drive links out of the bar nose.
Is it possible for a chain to stretch?
If roller chains are poorly lubricated, stretching will take place very quickly. When a chain has elongated 3% of its original length, it must be replaced.
Why does my chainsaw chain keep loosening?
Chain Not Set Properly One of the most common reasons why your chain might be coming loose is because it was not set properly. When you go through the steps to tension your chain, you need to finish those steps by setting the tension so it won’t change as you work your saw.
Can I take links out of a chainsaw chain?

How often should you tighten chainsaw chain?
The chain isn’t actually becoming tighter—instead, as you turn the tensioning pin—it pushes the chainsaw bar out a little bit, which takes up the slack on the chain. During a typical afternoon wood-cutting session that lasts 2 to 4 hours, you may need to tighten the chain two or three times.
How loose should a chain be?
It should be tight enough that it only allows you to move it up and down about one inch. If it is sagging or much looser than that, you need to tighten that chain up. Chains often loosen when a bike does not have a derailleur. Derailleur is the gear changing mechanism towards the back of the bike.
Can you over tighten a chainsaw chain?
There is a tension screw located near the base of the bar on the chainsaw. To tighten the chain, turn it clockwise, and to loosen turn it counterclockwise. Don’t over-tighten the chain as this could cause it to break.
How do I know if my chain is stretched?
Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.
What happens when a chain stretches?
Chain wear is commonly referred to as ‘chain stretch’, because the chain’s pitch grows in length as it wears. This is the most important type of chain wear, and the growth comes from the bushings wearing with the chain pins. Overtime, the inner diameter of these bushings increase and the pins groove out.
How do I stop my timing chain from stretching?
It is important to have your vehicle serviced regularly for oil changes—every 5,000 miles and with the correct oil. Doing so is the best preventive maintenance of timing chain stretch and hop.
How long does a chainsaw bar last?

Should you let a chainsaw warm up?
The gas engine in a gas chainsaw should warm up, but due to the engine’s small size, this will happen quickly. Normally the engine will run for a short time after startup before you really start using it, giving the oil enough time to warm up and lubricate all engine parts.
What happens when the chain on a chainsaw breaks?
Ed to answer your question same scenario, chain breaks the drive sprocket instantly disengages from the drive links. Chain stops. No whipping or flailing. Kick backs by far are the greatest danger of chainsaw operation next to struck byes from trees or parts of a tree.
