How to start a lawn mower? Pull the cord! Ok, we agree. Sometimes this is not enough. Given that some lawn mowers start differently, depending on the model, in this article we will give you some general tips. Continue reading!
Steps How To Start a Lawn Mower?
Fill the mower with gas and check the oil level in it. It is possible that you forgot to do this. It happens to everyone. But if there is no oil and gasoline in it, then you can pull the cord for at least a whole day, and you will not achieve anything but muscle pain and the chance that your children will learn from you not quite good words.
Open the fuel tank cap and look into it. If necessary, refuel the mower to the recommended level. The tank should have a marking to indicate to what level the tank should be filled, but if it is not, fill it up to the neck. Do not overfill the tank.
Remember to check the oil level. If there is not enough oil, then you can easily ruin the engine. Oil is usually poured through a cap on the top of the mower housing, which says “oil” or an oiler. Just like a car, your mower may have a special dipstick with which you can check the engine oil level.
Please note that some mowers (mainly with a two-stroke engine) use a fuel-oil mixture. If so, carefully read the user manual before refueling the mower.
Bleed the fuel pump! Find a soft cap next to the spark plug, usually red or black. Press it 3-4 times to fill the carburetor with gasoline. Just do not overdo it and do not fill the engine.
But not all mowers have such a pump. In this case, you will need to fully open the throttle.
Check out the candle. The candle should be near the engine and have a rubber cap. It produces a spark that starts the engine, so make sure the cap sits tightly on it.
Open the throttle. Shift the throttle lever to the middle or to the last position. Otherwise, the engine will not receive enough fuel to operate.
Use caution when starting the engine. Now, most new mowers come with a safety switch that must be held at startup. If your mower does not have such a switch, then make sure that it is stable on the ground.
Pull the cord sharply! Bend the mower body with one hand and grasp the cord with the other and pull it up sharply. You may need to do this several times before the engine starts.
If the engine sneezes but does not start, then check if there is enough gas in the tank.
If the engine does not sneeze and does not start, then check the spark plug.
Read the mower’s operating instructions. If the mower still does not start, read the instructions in the troubleshooting section. It is possible there will be an answer to your question.
Some Reasons
It often happens that users of such machines try to “save” by pouring into the tank not fuel with the usual octane number, but something incomprehensible that has been standing in a plastic canister for almost a dozen years.
Advice
➽ Always clean your lawnmower after work. Withered grass may adhere firmly to it. In addition, it smells bad when it begins to rot. Therefore, as soon as you finish mowing, clean the mower of grass.
➽ Never leave the mower for the winter with gasoline in the tank. During storage, it may thicken and clog the carburetor.
➽ Never run your mower without proper lubrication, unless you like to buy new mowers every time.
The Main Thing Is The Fuel Mixture!
In this case, the remnants of the plastic dissolved in the brutal environment do so terrible things in the combustion chamber that you can’t do without completely sorting out the mechanism. Gasoline self-propelled lawn mowers are the choice. But you certainly remember forever how to properly store fuel.
What, after all, is when the fuel was exactly normal, there is a spark, but the gas trimmer does not start? It may be that you just fill the candle with gasoline. In this case, you need to unscrew it, wipe it with a clean cloth, and dry it. More reliable electronic braid trimmers. By the way, checking the candle itself for performance will be completely out of place.
Reasons The Lawnmower Might Not Start
It doesn’t matter what equipment requires careful work and compliance with operating rules. As if the tool working during the check in the store after delivery to your home or several days of operation did not start. Before contacting a service center, you can try to solve the problem without the help of others. There are various malfunctioning conditions for gasoline and electronic lawn mowers.
A gas mower may not start for the following reasons:
➽ First, before starting the engine, you need to check the fuel in the tank. A small amount of it will create airiness in the system, but it is also impossible to fill the tank full to the brim. When refueling, you must adhere to the mark of the highest fuel level. If the lawnmower sets sail for winter storage, the fuel must be drained, because gasoline tends to evaporate. Fueling is done using a funnel. Before a case of spilled gasoline dries out on the mower parts, the engine must not be started in order to avoid ignition of combustible water.
➽ Often the engine of a lawn mower does not start due to the fact that the user does not know how to start it correctly. Before starting, the lever sets the maximum speed, and then pump gasoline into the carburetor with a primer. The starter cord is gently pulled a little over, and then sharply pulled.
➽ After unsuccessful attempts to start the engine, you can try to change the spark plug. Often the reason lies precisely in it. If there’s no spare candle at hand, and therefore the old one is roofed with heavy soot, it must be cleaned with fine-grained sandpaper.
➽ Clogged air cleaner results in the preparation of low-quality fuel mixture, and therefore the engine begins to stall or, generally, don’t start. to repair the matter easily rinse the removed filter in pure gasoline then dry it in air. Rinse the air filters every 25 hours, albeit the mower doesn’t stall.
➽ Immediately after starting, the engine may stall thanks to a jammed piston or crankshaft. Having unscrewed the sparking plug with a starter cord, it’s necessary to pump the engine several times. it’s possible that moving parts will develop and therefore the problem is going to be resolved.
➽ A low oil level within the crankcase may cause the engine to not start.
Electric lawnmowers even have their own easily solved problems:
➽ The commonplace reason that mower’s motor doesn’t work could also be a scarcity of electricity or low voltage. determine if there’s current within the network employing a screwdriver indicator, but you would like a multimeter to live voltage.
➽ The electric mower is provided with engine thermal protection. thanks to grass clogged ventilation holes, the protection will constantly operate, preventing the motor from running. Easily solve the matter by cleaning the ventilation holes.
➽ The explanation for the mower’s motor not working maybe a failed switch. Here you’ll need to contact the service center or replace the broken part yourself.
If none of the above tips helped to start out the unit, you are doing not got to touch anything, but it’s better to contact specialists.
Warnings
Try to stay away from the knives of the mower if there is even the slightest chance that it will start. Remember, all fun and games will end when someone loses their fingers!
How to Start a Trimmers
We start a Benz trimmer for mowing grass.
There are also more expensive gas mowers that include all 3 functions.
To adjust the height of mowing the lawn:
➽ Individual adjustment. Each unit wheel has a separate mowing height adjustment lever.
➽ Central adjustment. The adjustment lever simultaneously controls the entire cutting height.
➽ Screw adjustment. The most simple and inconvenient way to adjust the cutting height, in which the height is set manually when moving the wheel axis up / down.
By type of movement:
➽ Self-propelled. It has a drive that allows you to automatically move a gas mower. The main thing is to direct to the mowing area.
➽ Not self-propelled. The movement of the unit is carried out manually.
By type of drive:
➽ Front-wheel drive lawn mower. It is more maneuverable and is used in flat areas.
➽ Rear-wheel drive lawn mower. It is used when mowing grass in hilly areas, as more stable when driving with a load on the rear wheels (hill movement).
Mixing And Refueling a Two-Stroke Engine
Two-stroke engines do not run on pure gasoline. They will have to prepare the fuel mixture on their own. Gasoline should only be used with the octane rating recommended by the manufacturer. It is not necessary to use oil only from the company that the mower is. Any brand will do, the main thing is that it be a product for two-stroke engines.
Any lawn mower instruction contains information on the ratio of the components of the fuel mixture, that is, oil to gasoline. For example, for mineral oil, this figure is 1:35, but it is rarely produced for two-stroke engines now. Most often, a synthetic product is on sale. To prepare the fuel mixture to adhere to a ratio of 1:50.
Preparing the fuel mixture is quite simple. Pure gasoline is poured into a measuring canister and a certain amount of oil is added using a dispenser. Further, it remains to tightly close the lid of the canister, shake the liquid and the fuel will be ready. It remains with the help of a funnel to pour the prepared mixture into the gas tank and you can start a lawn mower.
Carburetor Again
Well, even if, after such bullying, your trimmer does not start, you can not do without disassembling the carburetor. It may well be that the dropping of the needle in it is to blame. In any case, disassembling and washing this capricious mechanism certainly will not hurt.
In general, when the trimmer began to act up and stall, it is advisable to carry out complete prophylaxis: completely change the fuel mixture, try another oil, and also change the candle without fail. Practice shows that in many cases cheap low-quality candles are to blame.
We examined the most common reasons why the trimmer does not start. If the matter is something more “exotic”, do not pass the trip to the service center. You will probably find smaller and more obvious damage yourself.
Four-Stroke Engine Mower Refueling
Many wheeled lawn mowers are equipped with a four-stroke engine. For such an assembly, the fuel mixture does not need to be prepared. Oil is poured into a separate filler hole and is located in the crankcase. Only clean gasoline is poured into the tank, after which the mower is ready for operation.
The design of the four-stroke engine of the mower does not include an oil filter. Due to the lack of a cleaning mechanism, oil is contaminated quickly and needs to be replaced after 50 hours. The entire replacement process is straightforward. The engine is allowed to idle for about 15 minutes to warm up. The drain hole is located on the crankcase. It is closed by a screw plug. The mower is installed at an angle to the side of the drain hole, a container is used to collect the used oil, and then the screw is unscrewed. When all the dirty oil drains, the cork is tightly closed, the mower is put on an even place and through the upper filler hole add new oil. For four-stroke engines, the brand 10W40 is usually used. The level is checked with a dipstick. When the desired mark is reached, the filler hole is tightly closed with a stopper.
Lawn Mower Rules A to Z
Working with any technique requires certain skills and getting used to it. If you have not had to deal with the operation of the lawn mower before, it is better to first familiarize yourself with the instructions that came with the machine. It will help to understand the purpose of each lever, then everything studied can be fixed by practice.
The lawn must be chosen straight without pits and knolls. When the dimensions of the lawn mower feel good, you can start trying to mow grass of different heights and learn to go around obstacles.
Work starts with starting the motor
So, the mower is filled with oil and gasoline, nothing flows anywhere, we proceed to the first test run of the engine:
➽ The first thing to do before starting the mower engine is to check the position of the speed knob. If the transmission is turned on, it must be turned off, otherwise, as soon as the engine starts, the mower starts moving on its own.
➽With the ignition turned off by a starter or a winding cord (it all depends on the design of the lawn mower), rotate the motor shaft. The air damper is within the open position.
➽The following actions consist of turning on the ignition and closing the air damper. Starting the starter of the mower is done by the button. If the engine is equipped with a winding cord, it must be pulled abruptly.
➽ If after several failed attempts the engine does not start, turn off the ignition, open the air damper and make a few idle strokes to purge the combustion chamber.
➽ Having finished with the purge, they repeat the same actions as they did the last time during the start of the motor.
When the lawnmower engine has successfully started up, it runs monotonously without jerking, using the high-speed lever, set the position with the desired speed, and begin to move.
Grass Cutting Height Adjustment
To achieve the required cutting height of the grass on the lawnmower there is a special lever that allows you to raise and lower the knives. Depending on the model, there may be two levers and the number of steps is different. For example, a 7-step adjustment allows you to adjust the cutting height from 20 to 70 mm.
It should be noted that soft grass is easier to mow with a low knife position. For hard grass, the knives will have to be raised, and the mower’s body adjusted with a forward inclination. Changing the angle of inclination of the body compensates for the deviation of the lawn mower with strong pressure on the handle. On front-wheel-drive lawn mowers, the body is not tilted forward, otherwise, the machine will leave passes on uncut grass.
We Expose The Handle of The Mower in its Height
To make grass mowing less tiring, you must correctly adjust the height of the handle of the mower. The optimal location of the handle is 3 cm above the center of gravity of the body. Although each person selects the location of the handle of the lawn mower individually according to their height and physique. There are special screws on the handle for adjustment.
Conclusion
Mowing grass is necessary without much effort. The lawn mower must itself move on the lawn, it only needs to be controlled. In difficult areas, it is better to switch to lower speeds, to change the direction of movement it is necessary to smoothly move the handle left or right. Extra efforts on the part of a person during operation will lead to rapid wear of the transmission and deformation of the knife on the ground.
