Chainsaw engines are traditionally either a two-stroke gasoline (petrol) internal combustion engine (usually with a cylinder volume of 30 to 120 cm3) or an electric motor driven by a battery or electric power cord.
One of the earliest patents for an “Endless chain saw” comprising a chain of links carrying saw teeth was granted to Frederick L. Magaw of Flatlands, New York in 1883, apparently for the purpose of producing boards by stretching the chain between grooved drums. “Usually, each segment in a chain features small, sharp, cutting teeth. Each tooth takes the form of a folded tab of chromium-plated steel with a sharp angular or curved corner and two beveled cutting edges, one on the top plate and one on the side plate. Left-handed and right-handed teeth are alternated in the chain. Chains are made in varying pitch and gauge; the pitch of a chain is defined as half of the length spanned by any three consecutive rivets, while the gauge is the thickness of the drive link where it fits into the guide bar. The conventional”full complement” chain has one tooth for every two drive links. Lack of chain oil, or using an oil of incorrect viscosity, is a common source of damage to chainsaws, and tends to lead to rapid wear of the bar, or the chain seizing or coming off the bar.
The clue is in the name! A chainsaw has two main parts: a saw blade built into a chain, wrapped around a long metal guide bar, and a small, one-cylinder gasoline engine. Chainsaw helmets with visors offer some protection; so too do chainsaw uniforms. Wayne’s Chainsaw Museum: A short video tour of Wayne Sutton’s chainsaw museum in the United States, will hundreds of saws dating from about the 1930s.
A chainsaw piston goes up and down in the cylinder 20,000 times per minute. The piston ring speed on the average chainsaw travels 2,500 surface feet per minute. Our largest chainsaw is one of the most powerful in the world.
what does a chainsaw run on Related Question:
What kind of 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.
Does a chainsaw need electricity?
Electric chainsaws come in two types: corded and cordless; and both versions operate the same way to drive the chain. The only difference between the two is how the chainsaw is powered. Corded chainsaws require electricity from an electrical outlet while cordless chainsaws run on batteries.
How do you mix oil and gas for a chainsaw?
Chainsaw oil mix ratios explained Say your chainsaw manufacturer recommends a 50:1 fuel/oil mix. This simply means you need 50 parts of gas to one part two-stroke oil. To mix one gallon of fuel at 50:1, add 2.6 ounces of two-stroke oil to one gallon of gas, as the top chart shows.
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 chainsaws take mixed fuel?
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.
What oil do I mix with chainsaw?
Many gas-powered chainsaws run on a 40:1 mixture of gasoline and 2-cycle engine oil. Other chainsaws run on a 50:1 mixture of gas and 2-cycle engine oil. Some older models use a 30:1 ratio. Check your chainsaw’s manual to be sure.
Why do I hear a chainsaw at night?
The sound of shrill cicadas pulsing in your brain, the roaring of chainsaws and the relentless wash of ocean waves, these are the sounds of Tinnitus.
Are chainsaws easy to use?
If you need to do regular maintenance in your backyard, perhaps removing branches here and there or cutting down small trees, then a small gas-powered chainsaw with a 16-to-18-inch bar is an irreplaceable tool. Due to the small weight and size of the chainsaws in that class, they are really easy to use.
Are electric chainsaws quieter?
With an average sound range of 90-102 decibels, electric chainsaws can’t exactly be called quiet. However, their sound range is 10-20 decibels lower than that of gas chainsaws. Because every 10 decibels represents a doubling of sound, this makes electric chainsaws two to three times quieter.
Can I use 2 stroke oil for chainsaw?
Is 2 stroke oil the same as chainsaw oil? Yes, 2-stroke oil is the same as chainsaw oil. However, a chainsaw engine could also be designed for a 4-stroke oil.
What happens if you put too much oil in 2-stroke?
Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power. While not ideal, these issues can be fixed by simply replacing the fuel in the tank with properly mixed fuel. But running a two-cycle engine with too little oil can actually destroy the unit.
What happens to a chainsaw without bar oil?
Without lubricant, the speed at which the chain moves over the chainsaw bar can cause some serious friction. A slowed-down chain and excessive fuel burning mean there’s a lot of friction between your bar and chain, which means a lot of heat is being produced that could do major damage to your saw.
Can I run 40/1 in my STIHL chainsaw?
Can I Run 40/1 In My Stihl Chainsaw? It is fine to use the same modern oil at 40:1 as well. Your OPE should always be properly tuned, as always. Oil concentrations in your saw will help protect your engine if you use it for heavy duty work such as milling.
What happens when you put gasoline in a 2-cycle engine?
If not, it’ll overheat. 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.
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.
