How to start a petrol trimmer Instructions for starting a lawn mower engine for the first time, starting a petrol trimmer with a warm engine and the main mistakes that should not be made when starting a 2-stroke engine.
Starting a warm engine
It’s very simple. Move the switch to the working position and pull the cord before starting. If you do everything according to the instructions, then there should be no problems with starting a working lawn mower.
How to start a petrol trimmer
The process of commissioning lawn mowers, whether you bought it now or got it after winter storage, the rules listed below will allow you to avoid basic mistakes that can damage the tool.
Let’s say you just bought a petrol trimmer. Take the instructions out of the box and see if you have all the parts listed for the lawn mower. After that you can start building.
Starting lawn mowers with cold engine
To start the mower for the first time, locate the choke lever and place it in the closed position. Turn on the ignition on the handle. If your model has a manual fuel pump, popularly called suction, then press it 3-5 times until you see the fuel mixture inside the primer. The tool is now ready to run. Place the trimmer on a flat surface to ensure a stable position. Pull the starter rope gently until you feel its resistance, and then pull the rope towards you with a sharp movement 3-5 times.
If the engine starts after 5 jerks, open the choke. If this does not happen, open the air damper anyway (if the damper is open and you continue trying to start the engine, the fuel will flood the candle and you will have to dry it, and this is a waste of time).
If the engine does not start when the throttle is open, close it and continue pulling the cord. The first launch can be quite difficult and require up to 15 jerks. After the engine has started to work, press the throttle lever once, so you engage idle. Now let the engine run and warm up. After that, it can be stopped by pressing the Stop button.
First start-up and running-in of lawn mowers
Correct initial start-up and running-in of a lawn mower are very important steps in getting started with a new tool. On the one hand, they allow you to preserve the service life of a gasoline engine, laid down by the manufacturer, since at this stage, the grinding of moving units and parts takes place. On the other hand, the first necessary skills of working with a trimmer are acquired when it comes to the first tool in life.
- Preparing for the first start of the lawn mower
- Inspection of the lawn mowers gearbox and its lubrication
- Preparing the correct fuel mixture
- Starting the trimmer for the first time
- Let’s start running lawn mowers
Preparing for the first start of the lawn mower
Before you start the lawn mowers for the first time, you must perform a number of sequential actions:
- Inspect the gearbox and lubricate it;
- Prepare the correct fuel mixture.
Preparing the correct fuel mixture
Before starting the running-in of the new engine of the lawn mowers, it is also necessary to properly prepare the fuel mixture. As is known for two-stroke engines, it is prepared from special two-stroke oil and gasoline, taken in certain ratios. You can find out the proportions from the instructions that came with the tool or on the lubricant label. From the instructions, you will also learn the recommended type of fuel, as well as the recommended type of engine oil.
When going to run in a new lawn mower, many are faced with a problem in preparing the fuel mixture. And the reason for this is the disagreement in the instructions of the tool manufacturer and in the instructions of the engine oil manufacturer. The former recommend a 1:25 ratio. The latter recommend 1:50. Whom to believe? How to proceed?
According to experts, if manufacturers write a ratio of 1:25 or 1:30 in the instructions for a lawn mower, then most likely this is either a cheap tool with poor cooling, or the manufacturer does not know what kind of oil the consumer will add. But here you need to understand that an excess of lubricant does not in the best way affect the performance of the trimmer. Excess oil does not completely burn out when the engine is running. It cokes, clogs the cylinder and piston.
How to deal with this situation when running in a new tool? The ideal option would be to purchase exactly the oil recommended by the lawn mower manufacturer. In the case of run-in engines, when it is not possible to purchase the recommended oil, it is best to purchase a good Husqvarna two-stroke oil for the gasoline-powered tool of the same name. It is not cheap, but it lasts for a long time. It is necessary to stir it as written in the instructions on the bank.
Checking the fuel mixture
Before starting the engine of the gasoline streamer, check the presence and quality of the fuel mixture. Do not save, do not be greedy and do not be clever in this matter. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepare the oil-fuel mixture strictly according to the instructions. Calculate its amount based on real needs. Excess gasoline left over after work loses its quality over time.
Breather and exhaust port
Often, delicate branded lawn mowers will not start and stall due to a dirty breather. The main function of this element is to equalize the pressure in the gas tank. When this unit becomes clogged, a vacuum is created in the tank, which prevents the supply of fuel. You can eliminate the malfunction by cleaning the breather. You can use a regular needle for cleaning.
Normal operation of streamers with internal combustion engines can be disrupted due to dirt entering the exhaust channel or a clogged silencer mesh. There is such a problem on older generation models. The issue can be resolved by traditional cleaning and removal of the anti-spark grid.
Lawn mowers filter diagnostics
Another reason why the gasoline scythe stalls is the air filter. To eliminate it, try removing the filter and starting the trimmer without it. If possible, then you will have to change the air filter to a new one, or at least blow through and thoroughly clean the old one.
The petrol trimmer may not start if the fuel filter is dirty. This is the next step in our algorithm. Here we check the condition of the filter element and, if necessary, replace it with a new one. When replacing, try not to leave the suction pipe completely without a filter, this is prohibited by any operating instructions. Haste can turn into repairing the engine piston group.
