Lawn mower does not start - Tips on causes and emergency aid
At the worst possible time your lawn mower will not start? That's no reason to panic. Fortunately, most devices are designed so that you can find out and fix the problem yourself. This guide gives you the most common causes and gives practical tips for emergency aid.
Cause: No fuel or no electricity
Surveys among the largest lawnmower producers showed it. If the mower does not start, an empty tank is one of the top 3 causes. Therefore, first check the available fuel quantity to fill up with fresh gasoline if necessary. If the engine has become hot as a result of repeated start attempts, wait until it cools down before filling.
The electric lawnmower can not run out of fuel. However, an electric mower will not respond if the plug is not properly connected to the outlet. If you can exclude this cause, check in the fuse box whether the associated fuse has been blown out. In most cases, a faulty power cable has triggered the short circuit and must be completely replaced.
Cause: Spark plug dirty or defective
If the spark ignited, the lawnmower will not make a sound. Take a close look at the spark plug because this is where one of the most common causes hides when the engine does not start. If you are not familiar with the position of the spark plug, the operating instructions provide detailed information. How to solve the problem from the world:
Replace the clean spark plug. If the mower still does not start, the spark plug is defective and should be replaced with a new one.
Cause: Air filter clogged
The engine of your mower is equipped with an air filter so that dirt particles do not clog the carburettor or enter the engine. At fixed 25-hour intervals, the filter should be cleaned. If the maintenance fails, the air filter clogs so massively that the engine does not start anymore. Most filter elements are made of foam or paper. How to make your lawnmower afloat again:
Reassemble the clean air filter and install it according to the instructions for use. Various manufacturers use dual air filters, consisting of an upstream foam element and a paper filter. You can dispose of this paper filter if it is completely soiled. On the other hand, foam air filters are designed to run for about 100 hours and work without paper, making it worthwhile cleaning with water and a fatliquoring agent.
Cause: cutter bar blocked
There is a close relationship between the cutterbar and the engine on the lawnmower, which only becomes apparent at second glance. If the starter rope is actuated when the cutter bar is blocked, the engine can not start. This problem often occurs when previously wet grass was cut. Grass clumps form, which get stuck between the knives. But also stones or branches can get caught. How to get your lawnmower going:
Before starting the cleaning, please check twice whether an unintentional starting of the motor is reliably prevented. For safety reasons, we recommend the petrol lawnmower to fix the spark plug cable so that it is sufficiently far away from the spark plug.
Cause: carburetor dirty
Regular contact of the motor with grass, leaves, twigs and soil can lead to deposits. So it is not uncommon that accumulated impurities in the carburetor clog the fuel and air supply hopelessly. In the end, the lawnmower will not start at all. How to approach the problem expertly:
Start the engine. If he jumps at short notice and leaves immediately, the carburettor should be cleaned. Often it is not necessary to remove the carburetor. In the specialized trade you can purchase carburetor cleaner as a spray, with the help of which the contaminants are removed from the outside.
Tips
Does the mower start and leave after a short time? Then the fuel is probably too old. If the gasoline in the tank is older than one month, important components can harden and the cold start capability decreases gradually. Replace the fuel, refuel with fresh gas or spray a little boost spray on the intake manifold (owner's manual).
