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. In a petrol chainsaw, fuel is generally supplied to the engine by a carburetor at the intake.
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.
These main parts work together in the above order to power and operate a chainsaw. Chainsaw maintenance varies depending on the type of chainsaw and the frequency of usage. The most popular ones include the best chainsaw for cutting firewood, what to look for in the best 18 inch chainsaw for bigger jobs, and the top rated chainsaws available.
how does a chainsaw get power Related Question:
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.
What energy does a chainsaw use?
Electric chainsaws receive energy by being plugged into an electrical outlet which powers a rod and crank assembly to power the circular motion of the chain.
Why does my chainsaw not have power?
Your chainsaw’s carburetor is intended to provide the optimal mix of fuel and air that will allow combustion. If your carburetor is not tuned properly, the mix can be off, and this will result in a lack of power in your chainsaw.
Can electric chainsaw cut trees?
Although electric chainsaws are smaller and easier to carry, most lack the power and stamina to cut down large trees. If you have big trees on your property that you want to remove or cut into firewood, a gas model is your best bet. Electric chainsaws come in two types: corded and battery-powered.

Was the chainsaw invented for childbirth?

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 motor work?
It has an air-cooled two-stroke gasoline engine. The chain is driven by a centrifugal clutch. When the engine is idling, the clutch is disengaged. When the engine speeds up, the centrifugal plates in the clutch spin outward to engage the clutch, and the chain begins running.
Why does my chainsaw dies when I give it throttle?
If the filter becomes clogged, not enough fuel will reach the engine for it to run properly. Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle.
Why does my Stihl chainsaw loses power?
When your Stihl MS 170 chainsaw drops its power under full load, it generally means there is an improper mixture of fuel and air in your carburetor. When you depress the trigger, a vent on the carburetor opens, allowing more gas to reach the mixing chamber.
What causes a chainsaw to bog?
Many chainsaw operators first notice a problem with chainsaws bogging down when they’re using the chainsaw under load, and this is usually the result of poor air circulation. This issue is caused by a clogged air filter on the chainsaw.
Are electric chainsaws quiet?
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.
Are electric chainsaws safer?
Because electric chainsaws are easier to operate than gas chainsaws, you may think that they’re a safer tool to use; however, that’s not necessarily the case. The truth is that all chainsaws present the same dangers regardless of how it’s powered.
