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.
If there is too much fuel mixed with the air, the engine “Runs rich” and either will not run, runs with a lot of smoke, runs poorly or, at the very least, wastes fuel. There is an adjustable plate across the tube called the throttle plate, which controls how much air can flow through the tube. One of these screws controls how much fuel flows into the venturi at full throttle.
The chain is the part of the chainsaw whose components do the actual cutting. The chain’s cutting part is called the cutter teeth or cutting link. Let us look at the cutting links that make the chain such a special component of the chainsaw.
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.
what do chainsaw runs on Related Question:
What does a chainsaw run on?
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.
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 get fuel?
A gas-powered chain saw’s engine functions much like that of a car. Simply put, the piston that drives the gears and chain is powered by energy released by combustion. Fuel in the tank is mixed with air when it’s pulled into the carburetor where it’s then ignited by a spark from the spark plug.
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.
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.
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 is my chainsaw flooding?
There could be various causes: incorrect fuel mixture, carburation not calibrated properly, or a wet spark plug. In spite of their power and robustness, chainsaws are actually rather delicate machines that require careful and precise maintenance at every stage of their life cycle.
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.
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.
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.
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.
What happens if you run 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.
How often should I oil my chainsaw chain?
Gas chainsaws use about one tank of bar and chain oil for every tank of fuel, so fill the reservoir every time you fill the tank.
How often should I oil my chainsaw?
It is recommended that you grease the bearing in the tip of the bar each time you refuel. Make sure to grease the tip at the end of the day as well to help prevent moisture from entering the bearing as the bar cools.
