Although childbirth remains a difficult, often stressful experience for mothers, the advent of opioid medications for labor pain relief and the use of appropriate sanitation methods has made childbirth far safer for mothers than was possible during previous periods in history. Although childbirth remains a difficult, often stressful experience for mothers, the advent of opioid medications for labor pain relief-such as morphine, fentanyl, nalbuphine, and butorphanol-and the use of appropriate sanitation methods, has made childbirth far safer for mothers than was possible during previous periods in history. In the article, Dr. John L. Richmond describes how, after many hours of the expectant mother being in labor, he could see she was close to death, requiring that he make a decision quickly to save the woman’s life.2,3.
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.
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 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.
how to test chainsaw coil Related Question:
How do I know if my chainsaw coil is bad?
If your multimeter displays a reading of zero, it is an indication that you must replace the coil of your chainsaw at once because it has short-circuited. If your multimeter displays a reading above the specified level it is an indication that you will also have to replace the coil of your chainsaw because it is open.
How many ohms should a chainsaw coil have?
As well as this, also attach it to the terminal that connects to the chainsaw’s spark plug. A coil’s secondary resistance range (on average) is from 6 thousand to 10 thousand ohms. However, you need to make use of your manual to confirm the right secondary readings of the chainsaw you own.
Can you test ignition coils?
The only safe way to test for spark is to use a spark plug tester tool. If a coil problem is suspected, measure the coil’s primary and secondary resistance with an ohmmeter. If either is out of specifications, the coil needs to be replaced.
How many ohms should an ignition coil have?
A typical value would read 0.4 – 2 ohms.
How do you test a coil on a Kohler multimeter?
Using one of the multimeter’s probes, contact the metal terminal of the coil and open the center opening. On the other probe, hold it between the ignition coil’s grounding terminal and the electrical terminal of the meter. Test reads 600 to 13,000 ohms on the meter. A coil’s secondary winding can fail if it does not.
How do you test a 12 volt ignition coil?
Insert one of the multimeter’s probes into the center opening of the coil, contacting the metal terminal inside the coil. Touch the second probe of the meter to the ignition coil’s grounding terminal. The meter should read 6,000 to 15,000 ohms. If it does not, the coil’s secondary winding is faulty.
What would cause no spark from coil?
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
