Running in the brushcutter. Gasoline trimmer running-in instructions.
The use of gasoline scythes is due to the need to treat yard or garden areas, outdoor areas. During use, the lawnmower, and in particular its mechanical components, is subjected to great stress from internal and external factors. To keep the tool in top condition and prevent it from breaking down for a long time, it requires a running-in period for the petrol lawnmower
before use. This is done in stationary conditions by a trained specialist or the owner of the product himself, because there are no complex operations in the process. The main thing is to know how to correctly run in the gasoline-powered tool, so as not to cause errors. This issue can also be addressed by a professional, who sells you a new, untested mower or performs overhauls to replace the drive units.
Explaining whether your gasoline trimmer needs running-in, let us highlight the advantages of such an event:
- The new tool is evenly lubricated;
- All parts are lapped;
- The product smoothly goes into the working mode;
- A comfortable examination of the tool is made in case of the need to regulate the interaction of mechanisms to stabilize the working processes.
The last point also allows you to check the quality of the engine during running-in after overhaul, when the smooth commissioning. This is also how you run it in after you’ve changed s in the engine, gearbox, and other mechanisms.
Choosing a grass trimmer for country houses. My experience
My Alpine’s reel exploded right under my feet as I was mowing weeds by the fence. When looking for this part I’ve had options for 1500-1800 (that was three years ago). Very expensive, as it seemed to me. A colleague here told me that he recently bought a powerful Baikal 4500 grass trimmer for only 4900 (. The price for everything is very attractive.
I immediately called to this company, but the manager upset me, saying that the same “Baikal” is no longer available. But he offered me a 2.5 kW lawn mower from the Chinese brand Safun for 4,000. In a word, he enticed me. In addition, I was pleased to buy a mower for the price of two spools for an Alpina grass trimmer. Among other things I really wanted to check how long the cheap Chinese model would work and whether the engine power was as stated in the description.
the grass trimmer my colleague bought, with a weight of a little over 5 kg and an engine capacity of 52 cm³ has a claimed power of 5.5 kW. It’s a miracle! It came with two blades and a spool of fishing line. The recommended thickness of the line. 2.4 mm, which seemed to me strange, because the engine power is twice as much than the proposed to me the Chinese Safun, and the recommended line for trimmer. thinner. “We mowed some weeds in the far corner of the property with the Baikal. It cuts the grass well, but after half an hour of work, I have the feeling that Safun copes with a similar task better, and it is with the claimed power of 2.5 kW.

Just recently his electric grass trimmer broke down and was fixed in a shop for a couple of thousand, but after the repair it broke down again, for good measure. I told him about my trimmer, bought for mere pennies, he thought a little and bought a similar, but more expensive. Procraft T-4350 for 6000. I didn’t feel lazy and went to his country house, helped him assemble the machine and tried to mow at the same time.

The stated engine power of the Procraft T-4350 lawnmower is 4.35 kW, but during test mowing I did not feel any difference with mine. Gasoline and fishing line consumption is high. The engine is quieter than the Safun. In my first season with this trimmer I mowed a total of 100 acres. The engine starts steadily both cold and hot. Mower power life is not usually listed in descriptions. I couldn’t find this information about my Safun trimmer. I had to judge it by the number of mowing jobs per season. The mower is in its third season. I regularly mow a 36-hectare garden plot. To date, the mower has covered 9 to 10 hectares.

Here I want to share my experiences with the grass trimmer and the small mistakes and failures I’ve had over the past three years.
To each his own needs
Proper operation starts with a smart choice. Evaluate your needs and choose the right machine for you.
Choose the technique according to your needs
It is not worth buying a high-powered machine if you only have, for example, small grass to mow on the lawn: It will cost more and use more fuel. and make more noise later on. The same as trying to “cut down” high weeds with a low-powered trimmer. both mature burdocks will stay in their place and you will ruin your technique.
Preparation of correct fuel mixture
Before you start running in your mower’s new engine, you need to mix the right fuel, too. As is known for two-stroke engines it is prepared from special two-stroke oil and gasoline taken in certain ratios. You can find the proportions in the instruction manual supplied with the machine or on the label of the lubricant. You may also learn the recommended fuel type and the recommended engine oil type from the manual.
Prepare fuel in small quantities, enough for one mowing. Use special plastic canisters for fuel, or separate glass or metal utensils. Oil is best taken with a medical syringe.
Going to run in a new lawnmower, many are faced with a problem in the preparation of the fuel mixture. And the reason for this is the discrepancy in the tool manufacturer’s instructions and in the engine oil manufacturer’s instructions. The first recommends the proportion 1:25. The latter recommends 1:50. Who to trust? What to do?
According to the experts’ opinion, if in the instructions of brushcutter manufacturers they write the proportion 1:25 or 1:30, then most likely it’s either a cheap tool with bad cooling or the producer doesn’t know what kind of oil the consumer is going to add. But here we have to understand that the excess of lubricant is not the best way to affect the performance of grass trimmer. Excess oil does not completely burn out during the operation of the engine. It cokes, clogs the cylinder and piston.
What to do in this situation when running in a new tool? The ideal is to buy the oil that the mower manufacturer recommends. In the case of running-in engines when you cannot buy the recommended oil it is better to buy a good Husqvarna two-stroke oil for the gasoline-powered tools of the same name. It’s not cheap, but it lasts a long time. It is necessary to mix it as it is written in the instruction on the jar.
Remember, it is best to use the proportion that the oil manufacturer gives. But it is better to find out by experiment if the oil ratio written on the lawn trimmer is a good match. If the proportion recommended by the manufacturer makes the engine leak oil and you can see the oil stains, you need to increase the proportion.
Inspecting the gearbox of the lawnmower and lubricating it
Checking the gearbox before starting the gasoline grass trimmer should be done on a regular basis. Lack of lubricant or a small amount of it increases friction of the gear reducer gear, working at quite high revolutions. The result is overheating of the gears as well. The gearbox of the brushcutter fails. To prevent the occurrence of such a failure during operation and helps regular inspection.
If you find, before starting the gasoline lawnmower, insufficient lubrication in the gearbox, or its absence in the housing put “LITOL”. To do this, unscrew the screw on the bend of the gear housing and pour “LITOL” in an amount of 1-2 ml.
Working with a gasoline trimmer for a long time, every 8-10 hours, add grease to the boom gearbox.
Use fuel with additives
Many people use gasoline with additives and additives to work with a brushcutter. In order for the device to work properly, you should choose fuel that has no additives. Otherwise, such fuel will have a negative effect on the oil seals. Parts will become soft and allow air particles to pass through.
As a conclusion, we can point out another popular mistake many users make. During the running-in period, the lawnmower must not be subjected to sudden pressure on the throttle key due to the needle jamming on the carburetor surface. Keep in mind that the throttle trigger also needs lapping for proper, long life, in particular, as well as all mechanics. The throttle trigger should be pressed smoothly and completely. After such careful movements the carburettor needle, like all mechanics, will be lapped gently.
How to run in parts?
The starting method described above is quite suitable even for Chinese technology. But sometimes it is impossible to start the first time or the grass trimmer stops immediately. In this case, similar manipulation is performed when closing the valve of the air duct. If then nothing works, you need to contact a professional. If the system works correctly, never start the unit immediately.
First the engine should idle for 5 minutes. Important: if the instructions specify a different time, you must follow the instructions. During the warm-up it is necessary to adjust the airflow. By setting the various positions of the air damper lever, they ensure that the cutting part does not move. After waiting for warm-up, open the choke fully and set the power to 50% of maximum.
Keep the lever in this position for about 20 seconds. 30 seconds. Lower the throttle to the minimum and let the brakes run for 30-40 seconds. Then they set the power to 20% and wait 10-15 minutes. The motor then shuts off and remains at rest for ¼ hour. When the grass trimmer has cooled down, the motor starts as already described, but first the flap opens.
Holding the gas for long periods of time should be avoided, as poorly trimmed parts can be damaged. Prolonged idling is also contraindicated. This will cause overheating. This completes the engine, after which you need to start the transmission. This procedure is done in an open area where soft, fresh grass is growing. It is mowed at 5. 10 minutes without a break, periodically working with 50-75% power.
After such a session, mowing stops for 20 or 25 minutes. Usually 3-4 cycles is enough for the grass trimmer to work properly for many years. often than not, they try to start the device before the first filling is complete.

Proper first startup and startup of the hedge trimmer are very important steps when starting a new tool. On the one hand, they allow you to save the motor life of the gasoline engine, laid down by the manufacturer, because at this stage there is a crushing of moving units and parts. On the other hand, the first necessary skills for working with a trimmer are acquired when we talk about the first tool in my life.

Getting ready for the first use of a lawn mower
Before you can get your lawnmower running for the first time, there are a number of steps that need to be completed sequentially:
We recommend performing them not only when buying a new grass trimmer, but also when preparing the old tool for the new season after storage.
Basic rules and techniques for using a brushcutter
To get good mowing results and long-lasting use of machines, it is crucial to correctly operate and take care of your brushcutter. Even if it is the first time you are holding a brushcutter, you will soon get the hang of correct mowing techniques. Simply turn the unit in a semi-circle from right to left, moving evenly forward.
On the following pages we show you the basic techniques and methods that can help you to mow even large areas in a short period of time, and to get the best out of your mowing.
The basic mowing technique is the most commonly used.
Because the cutting attachment rotates counterclockwise, it is more common to mow from the right to the left in working practice.The advantage of this technique is that the grass cuttings fall on an already mowed surface.
Large, flat surfaces. the right technique.
Large, even surfaces are best mowed square. You divide the area into squares, then always work along the outside towards the middle.
The basic technique in case of tall grass.
If you mow very tall grass or hard weeds it is recommended to go both ways: first you cut the higher part of the mowed grass in one cut to the right, and in the opposite direction (to the left) the lower part. Even in this case the grass cuttings are left lying on the left side.
Along the slope. mow after mow.
You make excellent progress by mowing in a straight line, especially on a slope: cut a swath parallel to the slope, then mow back along the mown swath. Then mow the next higher swath. And here the mowed grass is always placed on the already mowed surface.
Skilfully negotiate the obstacles. playfully mow.
To mow close to a tree or bush without damaging any branches or trunks, a cutting thread is best. If there are many plants at a small distance from each other, mowing around is suggested before mowing. To do this, use your brushcutter’s blade guard as a guide. Always mow along a tree or bush, and go around it. The trunk remains protected, the area around the trunk will be mowed.
The Husqvarna 128R is assembled and the engine runs in
The time to assemble the mower has come, but the weather was clearly not on our side: then the sun was shining heavily, then suddenly it started raining for no apparent reason. By lunchtime the weather cleared up, and we went outside to assemble our miracle mower.
I can not but lyrical digression:) The mower is so beautiful and colorful, I liked it so much, that I could not find a decent place for it in the garden.

I already felt sorry for mowing with it beforehand, I just wanted it to decorate the lawn or any other place. My husband made a joke. he said, that now it is necessary to build a separate garage for your favorite mower:)
Lawn mower in the garden
Well, it’s time to get back to the business part of it. My husband had no trouble at all assembling it. He began by assembling the handle, dashingly putting the throttle handle on it and fastening it securely.
Throttle knob on the handle
However, this was not without mishap!:) My husband was just about to attach the handle to the rod when I heard the sound of a car pulling up to our gate. My husband put aside what he had started and went to meet the guests. It turned out that it was my brother who had come to visit us. When he found out what we were doing he gladly volunteered to help us (I wish he hadn’t done that), telling my husband to drop the instructions and just look at the box, you can see everything there. how and what attaches. And then it began! My husband got ready to attach the handle to the boom.

The part that secures the handle to the rod
And my boys started frantically looking for the upper part of the mount with a screw:) They turned the house upside down in search of the lost part. And I just followed them on their heels and told them it couldn’t be! We couldn’t lose it anywhere! And it certainly couldn’t have been left out of the kit, if it was supposed to be there. it’s just impossible. Then the men shook everything in the gazebo and inspected all the surrounding areas. We couldn’t find anything so we decided to go to the market! With great difficulty I managed to persuade my husband to check all the accessories one more time, and, oh, my goodness! Suddenly it turned out that one small bag had not been unpacked at all. There was a small black plate and screws to it. And then the situation cleared up. You should have seen us laughing. Even the neighbors came running to find out what had happened. The assembly of the mower went very smoothly, without any questions. This is how the unfortunate attachment looked like, unlike the one on the package:)
Attaching of the handle to the rod.
Tightening the mount
It took a minute and the handle was in place
Then we quickly attached the suspension bracket by threading the throttle cable through the bottom of it. And we went to the market to fasten the protection of the fishing line and knife, what we did very easy and simply. The weather surprised us again: it started to rain very lightly. Blade guard
It took about 25 minutes to assemble the mower (not counting the time I foolishly spent looking for non-existent parts).

Next, my husband adjusted the suspension and crank to his height, spending about the same amount of time. Since we are about the same height, the setup suited me fine, too.
In order to start the engine, we prepared a fuel mixture consisting of Husqvarna brand oil and gasoline AI-92.

Pouring the fuel mixture into the tank.
The engine started with the fourth jerk and immediately started smokin’ hard, I even got a little scared, but as soon as my husband opened the valve the sound was smooth, pleasant, and the smokiness stopped. I could smell it, but it was very slight. The engine idled for about three minutes, and then we turned it off with a great sense of pride and accomplishment. No-load motor operation
The Husqvarna 128R was assembled correctly and runs in, leaving only positive emotions! Everything is so simple and well thought out that anyone can do it.
So far I have only this review (without expletives) about Husqvarna 128R
