With the chainsaw still securely on a flat surface, place your right foot on the rear handle of the saw while holding the top handle firmly with your left hand. Press the button a few times until you can visibly see the fuel for easier startup with fewer pulls to start the machine. If you’re using a model equipped with this feature such as a Husqvarna chainsaw, push in the decompression valve.Īnother added feature some models are equipped with is a fuel pump or a primer bulb. Some models feature a decompression control (known as Smart Start in some models) that aids in the startup of your chainsaw. Step 3 : Engage the Smart Start Decompression This keeps the chain from rotating on the bar as a safety measure. The next thing you want to do is activate the chain brake, found on the top handle, by pushing forward on it.

Remove the bar cover, if you haven’t already. The first thing you want to do is be sure to place the chainsaw on a flat surface such as the ground.

There are several things that can go wrong even in the highest quality models over time, but knowing what to look for will give you an idea if it’s something you can fix yourself or will need a professional to look at.įirst thing’s first, you must ensure that you are actually starting the chainsaw correctly. Understanding how your chainsaw works can provide clues as to what the problem might be when it stops working. It then burns, releasing its energy as it pushes the piston back and forth. The cylinder in the chainsaw’s engine works similarly to a cylinder in a car the fuel from the saw’s gas tank mixes with air through the carburetor where it gets passed through this cylinder and becomes ignited by a spark plug. A piston within the engine moves in and out of the cylinder and pushes on a connecting rod which results in the crankshaft turning gears that are connected causing the chain of the saw to spin along the guide bar. Inside the motor are gear wheels that turn the chain which allows it to run along the guide bar as you drive through tree limbs and lumber. They also all consist of a blade made up of sharpened steel alloy that is built within a chain (hence the name, chainsaw). No matter what type of chainsaw you have, one thing that is common in all of them is that they are operated by an engine. Chainsaw models will differ from one to another and while they often have different features and types from gas to electric, they all operate on a similar concept.

In order to understand what might be causing your chainsaw not to start, it’s a good idea to have a basic understanding of the mechanics that go on inside.
