A chainsaw is a handheld mechanical saw used in logging and forestry, most often to fell trees or cut branches and foliage. It is powered by a two-stroke engine, which rotates a chain of blades. The chain is made up of several teeth, which effectively cut through the material when used at a proper speed.
Chainsaws are also used in creating firebreaks, i.e., an area cleared of combustible vegetation to stop or slow a wildfire.
Perils of a Chainsaw
Though it is of immense help when it comes to wood cutting, chainsaw has some hazards associated with it. A machine that can cut through a tree trunk, can easily rip apart human body. (Initially, a device known as Osteotome, which was similar to the chainsaw, was used by surgeons to cut bones in surgery.)
Make sure that the shoes you wear allow you to have a proper foothold. Never wear loose clothing while using a chainsaw. And never work with a chainsaw, when you are not in your best health.
When starting the chainsaw, make sure that you are at least 30 feet away from any kind of fuel. There are chances of a fire breakout due to the sparks created when starting the motor.
Once you are ready with necessary precautions and safety gear, you can start it by pulling the starter cord. While doing this, place the machine on the ground and place your foot on it to hold it in place.
In order to trigger the ignition process the cord should rub against the starter housing and break, so the cord should be pulled straight up. Make sure that the cord doesn't touch anything while you pull it.
When cutting a trunk at a point higher than your reach, you can climb the tree and suspend yourself against it using a harness.
As a mechanical reaction, the chain can pull you into the work, when you use the bottom of the blade, or push you outwards, when you use the tip of the blade.
Therefore, make sure that you use the perfect stance and have a proper grip of the machine as well as your foothold. More of such jolts are expected when the machine abruptly comes to a halt, or when you are cutting a hard piece of wood using a blunt blade.
Technology comes at a price, but safety is definitely not the price you pay for it, even if it helps you work faster. A chainsaw is no doubt one of the most useful wood-cutting equipment, but that's only when you use it properly.
