If a lawn mower constantly stops, it doesn't necessarily have to be a serious technical defect. There are usually two causes responsible for the problem, which you can solve yourself. This guide explains what to do if a lawnmower keeps stopping.
What to do if the lawnmower keeps turning off?
If a lawn mower keeps stopping, check the gas level, the spark plug and, if necessary, the carburetor. Add fresh gasoline, clean or replace the spark plug, and clean the carburetor according to the owner's manual to resolve the problem.
Low fuel level makes lawnmowers powerless
If your lawnmower constantly refuses to work, first take a look at the fuel tank. If there is only a small amount of gasoline left in it, the mower will stop at every bump. The liquid sloshes back and forth in the tank, so that when the level is low, air gets into the fuel line and the engine stops. After you refill with new gasoline, the lawn mower runs without interruption.
Old gasoline causes the engine to die
Does the engine fail when you mow the lawn for the first time after the winter break? Then the fuel is too old. Without preservatives, the gasoline breaks down over the long break and can lead to resinification in the component system. Drain the old gasoline and fill with fresh fuel.
When the spark plug burns out, the engine runs out of steam
When a lawnmower stutters and puts a strain on your nerves with misfires, burnt spark plugs are one of the most common causes. If there is enough gasoline in the tank, check the spark plug carefully. How to do it right:
- Turn off the reluctant lawnmower and place it in the shade to cool down
- Remove the plug from the spark plug
- Take a spark plug wrench (€9.00 on Amazon) and unscrew the spark plug
The condition of the spark plug and contacts determines how to proceed. Please replace a badly burnt, deep black sooty candle. This also applies if cracks have formed in the porcelain. In all other cases, clean the spark plug and contacts with a brush and cloth without using water or liquid cleaner. Screw the spark plug back in, put the plug on it and continue your mowing work.
Tip
Does your lawnmower stall even though everything is ok with fuel and spark plugs? Then the carburetor becomes the culprit. Take the operating instructions at hand. Here you can read how you can clean and readjust the carburettor yourself.
