The original chainsaw looked more like a modern-day kitchen knife than what we would call a chainsaw nowadays. In the 1780s, in a bid to make the removal of the pelvic bone easier and less time-consuming two doctors named John Aitken and James Jeffray invented the chainsaw. In 1883, a patent for a chainsaw for cutting boards was passed and then subsequently more and more chainsaws developed.
The original chainsaw was invented and used by two Scottish doctors in the 1780s. Interestingly, it’s also the first Stihl chainsaw because the first wood chainsaw was invented by Andreas Stihl – the founder of the Stihl chainsaw company. Stihl also claims to have invented the first chainsaw for use by one person in 1950 – check out all the Stihl chainsaw years made for more info.
Now people are obsessing over the origins of the chainsaw, after TikTok user hellomynamesjon shared a video saying it was first invented to help with childbirth, which sounds more than a little terrifying. Yes, the first chainsaw really was invented to be used in childbirth – though thankfully it was a far cry from the electric-powered monsters people cut down trees with today. Modern chainsaws come in many sizes, from small electric saws intended for home and garden use, to large “Lumberjack” saws.
The modern-day chainsaws we’re used to seeing are mainly utilised for tree cutting. Shockingly, the chainsaw was originally invented to assist in childbirth – yes, you read that correctly. The doctors’ chainsaw was used during symphysiotomies.
what causes a chainsaw to lose compression Related Question:
How do you increase compression on a chainsaw?
Too much or too little air intake can negatively affect engine compression. In order to increase compression in your Poulan chain saw’s Kohler engine, manually adjust the air valves via the two rocker arms under the air valve cover.
Can low compression Be Fixed?
If you discover you do have low compression, the only solution is to replace the leaking part whether it’s the piston, piston ring, camshaft, head gasket or valves.
What causes a small engine to lose compression?
A loss of compression may result when the pistons are worn, the seals around your pistons are worn, or a push rod has become bent or broken.
What should compression be on a chainsaw?
According to Stihl USA, the minimum compression reading for their chainsaws should be around 110 psi. Some individual engines may run a bit higher or lower and the temperature of the tool can affect readings.
What should the compression be on a Husqvarna 55 chainsaw?
Re: Husky 55 Imo 125 psi is fine.
How much does it cost to fix engine no compression?
It will normally cost you between $100 and $200 to have a professional mechanic fix the low compression in one cylinder. The repair alone will cost you, but you will have to consider the replacement of other damaged parts as well. It costs between $1000 and $2000 to repair a head gasket.
Can a blown head gasket cause low compression?
#4 – Head Gasket Failure This is known as a blown head gasket and causes the gases in the cylinder to leak out of the hole in the gasket. Then you will have low compression and a poor performance. If the head gasket fails between two cylinders, it can cause a compression leak in both.
Will an engine run even with low compression?
Will an engine run even with low compression? This depends on the cylinders that have low compression. If only a single cylinder has low compression issues, the engine will likely run. However, you’ll notice a decline in engine power as you drive, and you may not be able to operate the car in some terrains.
Can you check compression by hand?
Can I Do A Compression Test By Hand? It is possible to test this yourself with a compression tester, a few hand tools, and 20 minutes. The first step is to remove the fuel pump and fuel injection fuse. Using a spark plug hole, start the threaded end of the compression gauge.
Can carbon build up cause low compression?
If the carbon buildup is on the piston rings or ring grooves, it can prevent the rings from sealing properly, thus creating low compression.
What happens if engine compression is too low?
This can cause deep scratches in the cylinder walls, which can cause the compression to leak down into the crankcase. If you have a very old engine, it can also happen that these cylinder walls are just worn, and therefore the piston rings will not be able to seal properly.
Can a loose timing chain cause low compression?
You should be looking at bad head gasket, bent valves, or bad piston rings. Those are the culprits of low compression. The cam chain tensioner When really, really shot, can cause misfires due to timing being off from a slack chain, but yours both look taught.
Will a chainsaw run with low compression?
Most chainsaws will operate well with compression readings that range from 100 to 160 psi. After checking the function of the starter assembly, the operator can move on to determining if compression is dropping or increasing.
What causes a chainsaw to kick back when starting?
There are two circumstances that can cause kickback when using a chain saw. The first occurs when the moving chain at the tip or the nose of the guide bar strikes an object. The second situation is when the wood closes in, pinching the saw chain in the middle of the cut.
How much compression does a 2 stroke need to run?
It is advisable to read between 110–130 PSI on two-stroke engines. You should still expect a great engine in these environments as compression rates have fallen below 80 or 90.
