How to start a lawn mower correctly?

Every gardener or person who lives in a country house on a permanent basis should have a lawn mower, which will greatly facilitate the maintenance of the lawn located on the site or outside of it.

And in order for such a technical unit to serve you for many years, it is necessary not only to properly and carefully operate it, but also to know how to properly start the device and prevent possible breakdowns associated with this process.

To easily start the lawn mower, you need to read the step-by-step instructions in more detail, but you also need to take into account the rules for refueling the device with fuel, as well as many other important nuances.

Before starting, only gasoline models need refueling, the engine of which will not work correctly or will not start at all without correctly selected fuel. Therefore, having studied in more detail the technical characteristics of your device, you must also familiarize yourself with information about the finished fuel or about preparing a special mixture with your own hands.

In the latter case, it is necessary to observe the proportions that are specially calculated for the correct functioning of the mechanism.

Sometimes synthetic oils are used for this. These types of fuel mixtures have a lower cost, but practically do not differ in their quality characteristics. For 100 grams of synthetic oil, it is necessary to use 5 liters of gasoline, so the mixture will have a ratio of 1: 50.

Mixtures with mineral oils have a higher cost, since they are considered more natural and environmentally friendly, but in terms of technical characteristics, they are only slightly superior to synthetic options. The proportions when using such materials will be 1: 35, that is, 3.5 liters of gasoline should be used per 100 grams of oil.

There are also options for gasoline lawn mowers where the fuel tank is separate from the oil sump, so no mixing is necessary.

Depending on the model of the lawnmower, starting will be done in different ways. Therefore, it is necessary to take this into account and, comparing with the individual technical characteristics, proceed to connect the device and start the engine.

And if everything is quite simple with a manual model working on the principle of a regular braid, then some difficulties may arise when starting a petrol model.

The petrol lawnmower can be started in two ways - cold or warm engine.

Before starting a cold engine, you must take care of turning off the ignition and transmission systems, and also turn the engine shaft with the starting lever or starter. After that, you can start launching, proceeding as follows:

• first you need to turn on the ignition;
• then it is necessary to close the air damper;
• then you can safely start starting the engine.

After starting, you need to set the idle speed on the device, using the throttle lever. Then, using the same lever, you need to switch the device to work at low revs, thereby giving the engine the opportunity to warm up.After that, you can safely start operating the lawn mower at full power. It is worth noting that starting the device with a cold engine is permissible, but further operation in this state is undesirable, since this will negatively affect the general condition and functioning of the lawn mower.

Starting the lawnmower with a warm engine is much easier because the process does not require any prior preparation. In this case, actions must be performed in the following sequence:

• the control lever must be switched to the fuel supply mode at the maximum level;
• then you need to start the engine;
• then you can select the required speed and start working.

Starting a lawn mower after the winter can be quite challenging, since most of the time this type of appliance is stored in sheds where heating is not provided, which means that it is exposed to the harsh winter climate, and sometimes to sudden temperature changes. That's why it is necessary to approach this process wisely and take into account all important nuances.

For example, the first thing after a winter shutdown is to check the fuel tank of the device to make sure that it is clean and there is no old fuel. If the tank is not empty, then it should be cleaned before refueling. This must be done because adding new fuel to the old one that has survived the winter downtime is unsafe for the device to function. Old fuel, under the influence of the winter temperature regime, can slightly change its composition, which, when mixed with a newer composition or even with simple operation, can lead to malfunctions.

Further, for safer operation, you should act on the principle of turning on the device with the engine warming up. This will gently prepare the mower for use.

When starting up such a technical unit, some problems may arise, and in order to understand why the lawn mower does not start, it is necessary to identify the reasons, and for further work, eliminate them.

The main reason for problems when starting the lawn mower may lie in the fact that there is no gas in the fuel tank. or its quantity is insufficient for the operation of the device. In this case, it is obvious that what needs to be done is to fill the tank with fuel, and in order to prevent such a situation, it is necessary to check the presence of gasoline in advance.

Failure to comply with the rules for preparing fuel mixtures, as well as the use of low-quality raw materials in order to save money, can also lead to errors when starting and when operating the lawn mower. The way out in this situation is simple - it is necessary to carefully choose the finished fuel, as well as carefully observe the proportions when preparing the mixtures with your own hands.

Starting errors can occur because fuel can flood the spark plugs. This is due to prolonged exposure to the starter rope when the air damper is closed. To prevent this, it must always be checked and, if necessary, returned to the correct position.

Naturally, If you start the mower with the ignition off, you may fail, as without this the device cannot function.

Despite the difference in the characteristics and appearance of various device models, they still have the same causes of breakdown, so they practically do not differ in the way of elimination.

The most common problem with the device is that it will not start or stall when you press the gas.The reasons lie in the improper functioning of the carburetor or ignition, as well as in problems with the filtration system.

If the reasons lie in the operation of the ignition system, then proceed as follows.

• Make sure you are using fully functional spark plugs and that they are free of traces of fuel. If the candle is flooded, it is recommended to thoroughly clean it, as otherwise the device will not work.
• If the threaded connection is too dry, problems may arise during starting, because without lubrication with gasoline, a spark cannot appear or its power will not be enough for operation.
• In case of breakdowns in the ignition system, you should also check the contact between the spark plug and the high-voltage wire, since in its absence, the occurrence of a spark will be impossible, as well as further operation.

If the device stops working after 5-10 minutes after starting operation with a load at high speed, the reasons may lie in problems with the air and fuel filtration system:

• the filter can be clogged, so when it heats up, the system stops cleaning properly and turns off;
• the reason may also lie in the fact that the part responsible for adjusting the pressure in the fuel tank becomes dirty and blocks the fuel supply.

There are also more serious breakdowns that can be quite difficult to deal with.

• The channels and nozzles of the device can be seriously contaminated, so you cannot do without capital cleaning. And in order to clean them correctly, you need to use professional tools and blow through the parts with a powerful air stream.
• Often, the gaskets that are an integral part of the system wear out and also fail in the working system. They cannot be repaired, so you just need to replace them.
• Worn pistons in service can cause damage. That is why the details must be monitored and, if necessary, changed.
• In addition, the cause of a breakdown may be a leakage in the carburetor space.

Before you start working on the lawn mower, you need to study the instructions for its operation in more detail. But, in addition, it is recommended to also adhere to some general rules.

• Use the device with extreme caution, avoiding contact with hard surfaces and body parts.
• It is recommended to clean the housing and working parts of the device after each use.
• It is necessary to clean the mower using special professional fluids, after waiting for its engine to cool down, since it is unsafe to clean a hot motor.
• It is best to take breaks while working. This will prevent the engine from overheating.
• If you do not plan to operate the device for a long time, it is recommended to drain the remaining fuel and leave the device in idling mode. When the last remaining fuel is used up, the mower will stop working by itself.
• And, of course, after summer use, do not forget to properly prepare the device for winter, then it will serve you for many years.
