My chainsaw Won’t Start: How to Fix This.
Chainsaw won’t start- what now?
A chainsaw is a useful tool for homeowners until it stops functioning appropriately. When the chainsaw doesn’t start, it can cause an immense setback with a project. It could also set you back financially for repairs. In this guide, you will learn common issues that can arise with chainsaws and their possible solutions.
For many chainsaw users, once it stops working, it is an indication that it should be tossed and a new one bought. The device may be past its warranty, and therefore some owners can feel like it is worth purchasing a new one instead of paying for the repairs. Nevertheless, there are simple solutions you can invest in that can get your chainsaw running at little or no expense while giving you more years of use. To understand what may be causing problems in the starting of your chain saw, it is crucial to comprehend the internal mechanisms of the device.
Underlying Mechanisms of a Chainsaw
There are different chainsaw models on the market. They come in unique features and types, including gas and electric. But they all operate on one concept. Regardless of the nature of chainsaw you have, one element is common in them all- they are operated using an engine. The machines also have a blade made of sharpened steel and alloy built in the chain. Inside the motor, you will find gear wheels which turn the chain, thereby allowing it to run along that guide bar as you drive into the tree limbs as well as the lumber. Then there is the piston in the engine. This feature moves in and out of the machine’s cylinder while pushing through a connecting rod resulting in a crankshaft turning gears connected causing the device’s chain to spin on the guide bar. Understanding how your chainsaw works can help you with clues as to what the impending issues can be when it stops working. Several things can go wrong even in some of the highest quality models. Knowing exactly what to look for should give you a rough idea of how to fix the machine or if you will need to look for a professional to do it.
Troubleshooting the Chainsaw
You have done everything right. However, your chainsaw will not just start regardless of the number of times you have pulled the starter. There are possible causes that you may check and be able to resolve on your own.
Then there are times when all you need to do is replace a few broken parts not functioning correctly. These can be purchase online or from hardware stores roughly at a fraction of the amount it would cost you from a mechanic.
Here are common areas to check that can cause the chainsaw not to start and their possible solutions:
Check the spark plugs.
The first thing you need to check is whether or not the plug ignites a spark because the spark’s responsibility is initiating combustion in the cylinder. It is common for spark plugs to corrode with time. To check if it gives off a spark, you should first remove it and use a plug wire in making contact with the engine of the machine. Observe the electrodes. If it does not, you can use a steel brush to remove the corrosion. And it still does not ignite after cleaning then it is time to replace it with another spark plug.
Check the tank for fuel supply.
Every chainsaw has a fuel tank that needs to be replenished now and again. There are three primary fuel-related checks to make. They include checking the fuel mix, blockages, and cracked lines. Start by emptying the tank then replace it with excellent quality fuel mix. And if the chainsaw has progressively been standing for an extended period with fuel in the tank, then probably it is contaminated—research on how you can mix two types of fuel. You may discover that the fuel filter is blocked. At this moment, a cleaner can help. Invest in a fuel system cleaner and add it to the fuel tank. Allow it to sit for five hours. You should then begin to add more fuel to the tank and give it time to redistribute into the cleaner throughout the engine. In case there are serious blockages, this should help in removing them.
Note- checking the tank is recommended especially if the fuel has been sitting in there for quite some time. You need to replace such fuel with fresh fuel. If your engine uses a mixture of fuels, consider getting such. Do not use boat oil or gas mixed with ethanol since it can damage your chainsaw’s machine. There is no generic ratio for chainsaws. Therefore, rest assured to refer to the manual on the gas ratio specifications for your model.
Check the ignition coil.
Chainsaws and other small two-cycle engines that operate using recoil starters use ignition coils because these instruments are essential in the device’s starting process. A defective ignition coil can easily be a culprit when the engine fails to start. This can send the voltage to that spark plug when the chainsaw is running. If you have assessed the plugs and cleaned them or replaced them with a new one but are still experiencing starting challenges, then the ignition coil could be the issue. Use a tester to determine this. Is it defective or not? If it happens to be, then you will have to replace it.
It could be the coil starter.
The recoil starter comprises of several different elements which help initiate the engine, particularly when starting the machine. Various issues may arise with these elements and can prevent your chainsaw from starting. For instance, there could be the rewind spring reels in the rope of the starter once it has been pulled and then released onto the pulley of the recoil starter. On that note, if the rewind spring is not fully functioning correctly, then the starter rope may not be in a position to recoil onto the pulley. This will make the starting of the chainsaw difficult. It may be impossible all the same. You should consider purchasing a new coil starter by replacing the rewind springs of the chainsaw.
Watch out for the dirty air filters.
A chainsaw has an air filter. This component supports the proper functioning of the machine. When the filter is clogged, it may interfere with the starting of the chainsaw. Such filters are known to draw more gas and not air. This is similar to when there is some choke on. Running a chainsaw with clogged filters can increase carbon deposits since the engine is known for producing unburned fuel. Another causative agent for carbon build-up could be an idling engine.
It is highly recommended that you give the machine a regular hard run to facilitate its operation. This is especially true if you have a smaller model. If you have used the chainsaw for more than 6 hours, then you need to remove the air filter and then use soap and water to clean it. Your chainsaw should start.
It could be the clutch pads.
Inspect the machine’s clutch pads for wear.
If the engine of your chainsaw is not running, then it may be as a result of overused, worn-out clutch pads. If they are worn out from continuous usage, they will not engage the clutch drum, which is an essential feature of the device that spearheads the turning of the chain. An additional possible cause for your chainsaw not to turn is if the level has not been activated. Disintegrate to make sure that this is not the actual cause. And if the clutch pads are not in excellent operating condition, then the clutch assembly should be replaced.
The Final Thoughts
As with any power tool, your chainsaw has several moving parts in the motor. People often tend to ignore the need to maintain this machine and care for it. They believe that excellent working machines are naturally built to work well. With time, the use of your chainsaw should wear out the parts. That is why there is a need to check the parts regularly. To accomplish this, you need to clean and maintain the necessary components as this can be effective in preventing common future problems, including the starting of your chainsaw. You also need to recognize the fact that you will enjoy more extended usage out of the tool if you take care of it.
How?
- Ensure that you make the necessary adjustments to it to tighten the nuts as well as tension on your chain
- Cleanliness is an essential routine to maintain the proper functioning of your chainsaw machine. Clean off, remove parts such as debris and sawdust
- Go ahead and inspect the blade’s sharpness.
- Make sure that all the moving parts of the machine including gears are adequately lubricated
