Nearly all gas chainsaws require a gasoline and oil mixture for their fuel. Chainsaw engines require a premixed fuel to keep them running at the proper temperatures. The oil that’s added to the fuel lubricates the piston and crankshaft, but it also keeps the engine cool enough to keep running.
If you have a lot of work for your chainsaw, it is good to know how long you can run your machine before you have to add gas or change/charge the battery. STIHL claims a forty-five-minute runtime with a chainsaw and battery, but it is hard to equate what runtime minutes mean with a chainsaw. If you want to store your chainsaw for a long time and find it seeping oil for many days, then the problem is with the vacuum relief valve.
Knowing the available chainsaw oil options, learning how to choose the right one and determining the right fuel/oil ratio can help ensure your chainsaw runs smoothly every time. Common Issues if Chainsaw Oil Is Bad. Chainsaw engine oil can go bad. Two-cycle oil is good for up to five years when sealed, and many manufacturers list the oil’s shelf life on the container. “One thing we do for our customers who buy a chainsaw that requires an oil/gas mix is we have them buy a gas can and we write the formula right on the can with a big black Sharpie. Then, the next time they need to make the mixture, they can dump in the right amount of oil and take the can to the gas station and pump in the right amount of gas.”
what does a chainsaw run off of Related Question:
What fuel does a chainsaw use?
Unleaded gasoline with a minimum octane rating of 89 is recommended. A lower octane can cause some issues, such as increased engine temperature, increased piston seizures, and engine damage. Stihl offers 2-cycle oils made especially for Stihl chainsaws. Premium quality 2-cycle fuels provide protection for your engine.
How does a chainsaw run?
Chainsaws use a centrifugal clutch, which automatically engages when the engine spins at high speed (when the saw is actually chopping wood) and disengages when it’s running more slowly (idling, in other words). A centrifugal clutch is really simple and consists of just a few parts.
Does a chainsaw need engine oil?
To run properly, all chainsaws need two types of oil for different jobs. The first is engine oil. The chainsaw shown here has a two-stroke engine, so it needs two-stroke engine oil mixed with the fuel to help cool and lubricate the moving parts inside the motor.
Do electric chainsaws need bar oil?
Electric chain saws derive their power from an electric source, so they don’t need fuel to run. Most gas chain saws require a premixed gas-and-oil fuel to operate properly. Electric chain saws don’t require this added oil, but the bar and chain do need to be properly lubricated.
What happens if you put regular gas in a chainsaw?
If straight gas is used, it can damage and ruin the piston and crankcase within a minute, as the gas doesn’t take long to burn out these sensitive parts. Drain the tank immediately into a separate fuel container.
Can I use chainsaw to cut wood?
Yes, you can use a chainsaw to cut wet wood.
Can a chainsaw cut through screws?
Commercial or Professional-use Chainsaws: In addition to having a powerful engine, these heavy-duty chainsaws have durable and reinforced teeth that allow you to cut through nails and other metal particles stuck inside the wood.
How does a chainsaw cut wood?
A chainsaw is a portable saw that cuts through wood or wooden objects by the use of “teeth” running in a circular motion around a guiding bar. The “teeth” on the blade of a chainsaw is actually a metal chain that has notches or grooves at certain intervals to cut through even the hardest types of wood with ease.
What oil does a chainsaw need?
Petroleum-based bar oil has been the standard for chainsaws. Lightweight oil is used in winter and heavier oil in summer. Manufacturers of chainsaws make bar and chain oils specially blended for their machines to extend their lifespan, but if they are not available, the owner’s manual suggests alternatives.
How long can a chainsaw run on a tank of gas?
What is the runtime of a Chainsaw? Depending on the type and usage, you can expect a gas Chainsaw to run between 15 and 40 min before you have to fill it up again. Most battery-powered chainsaws have a run time of up to 2 hours, but there are high-capacity power packs that will last much longer.
Do you mix oil with gas for chainsaw?
Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil. Knowing the proper way to mix your fuel is the first step in keeping it running strong and long.
Can you use 10w40 in a chainsaw?
You can but it’s not very good for the chain or the environment. The Husqvarna / Stihl stuff is much thicker and vegetable based so it doesn’t fling off the chain as easily or poison your garden! 10w30. Thicker.
Can I use 10w30 for chainsaw bar oil?
As a matter of fact, you can actually use regular 10w30 motor oil on a chainsaw as one of the alternatives in case you don’t have bar and chain oil. That’s because 10w30 oil has enough thickness and viscosity that will allow it to withstand the friction that is happening whenever you are using a chainsaw.
Should I use premium gas in my chainsaw?
To start, both Stihl and Husqvarna recommend the use of high octane unleaded gasoline. Both brands of pro saws are designed to burn fuel rated at 89 octane or higher. Most regular grade fuel has an octane rating of about 87.
What happens if you run straight gas in a 2 stroke?
Without lubrication, it’ll cause high friction, causing heat and causing metal filings from the piston rings knocking around, and losing a seal. In a way, oil counteracts all of these. If it’ll still turn over, flush the fuel, and put in the correct mixture of petrol and oil.
