A chainsaw is a powerful tool with various capabilities that can be used to make pruning and cutting operations much easier and faster than tools such as boxers, axes and hand saws.
Today, chainsaws are called chainsaws and saws. Gasoline is also called a versatile tool that not performing a proper service and maintenance program can cause damage to various parts of the device.
Damage to the parts of the chainsaw machine if not followed up in time and the repair process is not done, and also if the broken machine is still used, will cause damage to the saw and it is even possible that the chainsaw will be unused.
It should be noted that in this article from the Nika corp website, we try to discuss the most common defects that may occur in a chainsaw and also explain the way to fix the problem.
Use this guide to perform a troubleshooting process in the event of a fault. Obviously, performing specialized repairs requires an experienced technical technician, who with the help of an expert can increase the working life of the device by eliminating the defects.
We will point out these defects in the following.
Chainsaw failure can occur for a variety of reasons, and you can see it in different ways. Here are some signs of a chainsaw failure:
1- Chain saw does not turn on
To check why the chainsaw does not turn on, pay attention to the following points.
If your chainsaw does not light up, the spark plug may be defective. To find out, remove the spark plug from the engine and check it. Note the following when reviewing:
Porcelain insulation of the candle may be broken.
Candle electrode burned or damaged.
Accumulated on carbon electrode and soot.
If you see such signs, you should replace the previous one with a new one.
Note: Checking and visiting the chainsaw motor spark plug should be done on a weekly basis, and you can also be informed about the time of replacing the motor spark plug by referring to the machine catalog.
The carburetor may be blocked. Carburetor clogging is often due to a lack of fuel in the engine for a long time. Over time, some of the compounds in the fuel evaporate, forming a thick, sticky layer.
This sticky fuel clogs the carburetor and prevents the engine from starting. In this case, if you are sure that the carburetor is clogged, you can open the carburetor and clean and wash the whole carburetor.
If this problem still persists after washing, you will need to replace a new carburetor.
Ignition system coil:
The coil's job is to send voltage to the spark plug head when the device is on. In case of a defect in the coil, the possibility of the engine not starting is high.
Make sure the spark plug is in good condition before replacing the coil.If the spark plug is intact, test the coil with a tester.
If there is a defect in the ignition, you must replace the coil.
Handle and starter cable:
The end of the starter handle cable is mounted to the motor crankshaft to start by pulling the cable and rotating the motor crankshaft.
If there is a defect in the connection of the starter cable to the crankshaft, the crankshaft will not rotate and as a result the chainsaw will not turn on.
To ensure this problem, disconnect the starter handle from the device and inspect its components to ensure that it is working properly.
If you want to test the starter handle and its components for soundness, do the following. Pull the starter cable.
If it is healthy, the cable should be easily pulled and the ball in the center of it should get stuck in the engine crankshaft, and by releasing it, the cable should be gathered on the spool.
If you notice a malfunction during this test, it means that you have to replace the starter handle in general.
2- The engine of the device is turned on and then turns off (stabilizing the engine)
To find out the cause of this problem, it is recommended to check the following items.
The spark plug is a small metal plate that prevents the spark plug from being transferred to other components. Over time, with the accumulation of soot, this igniter is blocked.
If this igniter is blocked, your device's engine will shut down or start working badly, which will cause the so-called engine to rip. You can use a wire brush to clean the spark plug.
Of course, it is recommended to replace the previous one with a new igniter.
Carburetor clogging mentioned earlier can also cause the engine to stall. The way to fix this defect is to wash the carburetor or replace it with a new carburetor.
The fuel filter may be blocked. Fuel filter blockage often occurs due to fuel remaining in the tank and becoming obsolete as the filter passes through the engine.
By keeping the fuel in the tank for a long time, some of the gasoline compounds evaporate, forming a thick, sticky layer.
The same sticky fuel can clog the filter and eventually shut down the engine after starting (stabilizing the engine).
If gasoline stays in the tank for a long time, drain it and replace it with new gasoline.
The engine air filter may be dirty or clogged. If the air filter is blocked, the chainsaw motor will receive a lot of fuel and insufficient air.
The so-called fuel to air ratio changes. The result of this phenomenon is the engine stalling and ripping. Always check the air filter. Replace if clogged.
3_ Chainsaw chains do not rotate
It is recommended to check the following items for the problem of not moving the chainsaw chains.
To turn the chainsaw chain, the clutch pads must be engaged with the drum.If the clutch pads are worn, the motor of the device will work, but the pads cannot engage with the clutch drum, so the chain cannot rotate.
If the clutch pads are worn, you must replace the clutch assembly in general.
Other signs of a chainsaw failure:
Abnormal carburetor operation due to fuel oil fouling, dirt and clogging of the carburetor
The chainsaw does not cut well, which can be due to the slowing of the blades or the misalignment of the chains
The chainsaw smokes too much. This defect is due to the concentrated ratio of gasoline and oil
The engine gets too hot. This is because the engine load is too high and a lot of carbon is deposited in the cylinders, the exhaust pipe gets out and the exhaust smoke does not come out well.
