To look after your garden properly, you need the right equipment, such as a thermal brushcutter. It’s a very practical tool for removing weeds and keeping your garden clean. However, over time and with repeated use, this machine can present a number of malfunctions, some of which are commonplace. In most cases, you can repair these faults yourself. But to do this, you need to know how to identify the faults, so you know what treatment to apply to get it back in good working order. Read this post to find out more about common brushcutter breakdowns.
Engine starts, but your machine idles
Your machine starts up, but doesn’t work properly. If you find yourself in this situation, check whether the filters are clogged or dirty. You can then clean them or replace them with parts compatible with your machine. It’s also possible that the fuel connection hose is clogged. If this is the case, remove the blockage with a strong wire or by blowing into it. But if it’s damaged or punctured, you’ll need to replace the hose.
If your machine continues to malfunction despite all the checks and repairs you’ve carried out, it’s highly likely that the carburettor is to blame. If this is the case, you’ll need to visit a specialist store or platform to find brushcutter carburettor models to suit your machine and its model. Since this is a complex part, it’s essential to find the right carburetor for your equipment to be sure of fixing the problem.
Finally, if your engine is running, it’s possible that the malfunction is due to the cutting device. You therefore need to check the moving parts when the machine starts up, such as the spool, drive shaft, etc. The machine starts up and then shuts down.
Machine starts up, then shuts down
If your brushcutter starts up and then shuts down, check that the fuel and air filters are clean. If these parts are clogged, the fuel-air mixture will no longer be rich enough to promote combustion. This is also the case when the fuel flow is insufficient.
You should also check that the carburetor is securely attached to the machine. It’s a good idea to check the tightness of the carburettor’s fixing screws, to make sure they’re properly tightened and that there are no problems. Indeed, when the brushcutter has been running for a long time, the carburettor fixing screws can become loose. What’s more, the air intake may no longer be in the right place. Use a screwdriver to refasten them. If your brushcutter’s diaphragm is faulty, you can buy a diaphragm kit to repair it.
Also check the condition of the fuel tank. For your brushcutter to work properly, it’s essential that the fuel tank is watertight. Check its condition, and that of the fuel cap. A depleted fuel mixture is usually the cause of sudden malfunctions. This depletion is often due to a faulty cap. You’ll need to replace this part with a suitable model.
