Remove grass residues from the cutting attachment and grass catcher.
After each use it is recommended to remove at least the coarsest dirt from the cutting elements. Immediate cleaning of the lawnmower prevents the blades of grass from drying out and the formation of stubborn deposits.
Take measures for your safety before you start. Always unplug or remove the battery from your electric lawnmower. In the case of petrol lawnmower, the pipette must be disconnected from the spark plug. This prevents the engine from restarting and the sharp blades from moving while you are handling the appliance. Even if the blades do not move, care must be taken. To avoid injury during cleaning, we recommend that you wear special gloves. These safety measures also apply to the short-term removal of small obstacles such as stones or lumps of earth that get caught in the cutting chamber by blocking the machine.
With an interrupted energy supply, secure the lawnmower in a position that facilitates cleaning by allowing access to the various elements. Some models can be flipped over, others can be tilted to the side. The important thing is not to choose the side with the air filter. In this way it does not get dirty easily. For petrol engines, make sure that no oil or fuel spills out.
First, remove the larger tufts of grass stuck in the wheels and cutting attachment. The blades can be turned again without any problems and/or the cylinder of the hand tools is easily manoeuvrable. Do not forget the cutting chamber. Because even at this point where the grass catcher bag is used, grass residues and dirt often accumulate. Over time, this can lead to clogging and the cut grass is no longer conveyed into the sack but remains on the grass or increases the internal clogging. By cleaning the lawnmower you no longer have to collect cutting waste and the effort for basic cleaning is reduced.
Cleaning the lawnmower – tips for basic cleaning
Depending on the frequency of use, we recommend that you carry out a basic cleaning after a couple of months, which also involves the internal chassis, the engine and, in the case of petrol appliances, the air filter and the carburettor. Other measures are required for thorough cleaning. Finer waste remains attached to the blades, in the inner chassis, on the outer jacket and on the base. Brush with a brush or brush with long, soft bristles.
Use a universal cloth for thorough cleaning. Wet wipes facilitate the cleaning procedure in the presence of dry dirt. It is not possible to use water on all parts of a lawnmower to clean it. Electric motors and metal parts in particular must be protected. The cutting devices and wheel bearings are mainly made of metal. For more gentle care, clean the metal parts with an oil-soaked cloth. The oil dissolves the incrustations and covers the metal with an oily protective layer that prevents rusting. Only the grass catcher bag can be rinsed with the water jet of a high-pressure cleaner. Use a compressed air spray for tight spaces in the lawn mower.
Do not forget the blades and act with caution. Always wear protective gloves and take care not to pinch your fingers. Hardened grass residues can be softened with oil and then removed with a thick cloth. It is important to remove all residues. Otherwise, they will attract moisture, resulting in rust stains and unsharpened blades. We recommend the use of a spray oil to reach hard-to-reach, sharp areas. It should also be used after cleaning to protect against corrosion-related failures.
Particularly stubborn incrustations should be carefully scratched. The most gentle method for metal parts and painted layers is to use a plastic ice scraper.
Cleaning a petrol mower
The engine of a petrol lawnmower requires more care. Grass and drains dirty the air filter and carburettor in particular. The oil needs to be changed after a couple of months. The general rule is: Clean the petrol lawnmower thoroughly after 25 hours of operation.
Cleaning the lawn mower air filter
Air filters prevent dirt from entering the carburettor and engine. Paper filter or Dual filter: over time it accumulates a lot of dirt. The discoloured air filters of a lawnmower should be cleaned to avoid engine failure and power loss. Do not use chemical cleaners, but remove the filter, carefully beat it and clean it with a dry cloth. If there is a stubborn dirt, and if this measure is ineffective, you just have to replace the filter. Also dust the body. Clean the greasy parts near the filter with a damp cloth and a little detergent. The filters must never absorb oil. Replace the filter correctly and seal the lawnmower.
Cleaning the carburettor of the lawnmower
If the engine is not started or the lawnmower is blocked during operation, this is often due to a dirty carburettor. Grass residues clog the machine. For this reason, we recommend that you proceed as follows:
- Empty the tank and pour the petrol temporarily into another container.
- Remove the carburettor connection element from the tank and clean it. Replace any fittings that are too clogged.
- Remove the carburetor. The procedure varies from model to model. For this you must follow the manufacturer’s instructions for use.
- Often, even the gaskets are dirty or leaking. They must be cleaned and/or replaced.
- Spray the carburetor with a special cleaning spray or dip it in a container full of petrol to remove stains. Remove stubborn dirt with a cloth.
- Since the spray and stain remover cannot reach the narrow interstices of the nozzles, other cleaning aids must be used. Encrusted dirt can be removed by piercing the nozzles with a thin wire.
- Refit the carburettor according to the operating instructions.
