Description and characteristics of lawn mowers 128R

Husqvarna trimmer won't start

The Husqvarna 128R petrol trimmer is designed for small to medium sized areas and is also suitable for cutting grass near hard-to-reach areas (beds, curbs). The tool is equipped with a two-stroke engine with a power of 0.8 kW or 1.1 HP. The rotation speed of the Husqvarna 128R lawnmower reaches 11,000 rpm. The engine is designed with E-Tech 2 technology, which significantly reduces the amount of exhaust gas produced by the trimmer. Its volume is 28 cm 3.

To make the tool turn on quickly even after a long period of inactivity, it has a built-in primer for priming fuel and the Smart Start system. The maximum working width is 45 cm. The Husqvarna 128R lawn mower is a petrol trimmer with a straight bar and professional handles, made in a bicycle style. This allows much better control over the work process and the direction of the tool. Straight boom designs are considered more reliable than curved ones. The bike handles can be folded to make it easier to transport lawn mowers.

The weight of the tool is 4.8 kg without filled with fuel, installed cutting parts and protective cover. This allows the 128R version of the Husqvarna lawnmower to be used for a long time without interruption. The fuel tank of the petrol trimmer is made of white plastic to make it easier to control the amount of fuel remaining in it. The gasoline container has a volume of 400 ml. To start the lawn mower, it is enough to gently pull on the cord, as the required starting force has been reduced by 40%.

The tool kit includes:

  • Knife with 4 blades for hard and tall grass or bushes;
  • Trimmer head (semi-automatic);
  • Harness for 2 shoulders;
  • A set of keys;
  • Bicycle handle;
  • Operation and maintenance manual;
  • Protective cover;
  • Non-separable bar.

The Husqvarna lawn mower start button automatically returns to the starting position for easier and faster re-engagement of the trimmer. A special blade for cutting the grass does not crush it, but puts it into swaths. The blade guard and the line trimmer are the same cover and do not need to be removed when changing the rig.

Husqvarna lawn mowers can also be repaired by hand, such as replacing a clogged air filter. over, it is located in a convenient and easily accessible place under the cover. No tools are needed to replace it. In the event of a breakdown, it is better to take the equipment to a service center, since ignorance of the principles of operation of individual parts can only aggravate the situation.

The most common malfunctions on Husqvarna 128R lawn mowers are ignition or fuel problems. In the first case, the petrol trimmer either stalls after a few tens of seconds, or does not start at all. To do this, inspect the condition of the spark plug. If it is wet, you will most likely need to adjust the carburetor correctly. Or the problem occurs due to improper start, then you should carefully study the instructions.

If the spark plug is dry, it means that the fuel mixture does not flow. This is most often due to a clogged fuel filter or hose. The filter should be replaced (it is better to do this every 3 months), and the hose should only be cleaned.

A gasoline trimmer of this model can last for many years, the main thing is to follow the operating rules and timely inspect and replace the necessary parts. over, the price of the Husqvarna 128R lawn mower is fully consistent with its quality and performance.

The Husqvarna 128R lawn mower is worthy of your attention

Husqvarna is engaged in the production of various equipment and tools for the home, garden, forest and construction. Husqvarna chainsaws, cultivators, shears, riders, Husqvarna lawn mowers and all other products are manufactured using only the latest developments and quality materials. It is thanks to the unrivaled reliability of the tools that Husqvarna is known worldwide and in great demand.

Husqvarna 128R lawn mowers overview –

I have been working with Husgwarn 128R for seven seasons on hay making. The volume of work is approximately 2-3 hectares per year. The positive aspects of this lawn mower: it is a chainsaw-like clutch design – it allows rebasing when mowing (gas release when pulling back). For seven years, the circular spring has stretched a little and the engagement occurs at lower revs, but this does not affect work and safety. The most important thing is never to burst or jam the clutch (unlike the Chinese ones). Unmatched profitability per 1 hectare does not exceed 10 liters of AI92 and depends only on the density of the grass and the correctly selected disc. Reliability speaks for itself – 7 seasons without repairs – even the candle with which it was sold. The shape of the casing and its location to the disc ensures that the grass is laid in the swath when the handle is correctly adjusted and attached to the knapsack suspension. Ergonomics and lightness make work a pleasure. Carburetor adjustment is simple and clear. When mowing lawns, three-blade discs with pointed blades with a diameter of 255 to 360 mm (the size is taken depending on the evenness of the lawn surface) are excellent – while the quality and performance are not comparable to the work of a fishing line. Disadvantages: Attaching the handle bar to the bar will make it redo right away – it does not hold, when tightened, the thread breaks. I drilled holes through and bolted them, but this season I replaced them with a calm one. The supplied Gross 255-4 disc should not be used on all herbs. Exclusively only on heavy ones – thick, dense and tall grass. On light grasses, he begins, like a flywheel, to spin the scythe to unnecessary turns. But there is not a word about this in the instructions. Well, there is one more thing – the growth of the mower, its maximum height is 180-182 cm. With a greater height and with correct adjustment, you will "warm" your back with the engine, or you will not be able to adjust the correct angle of the knives at all. The line cut on this braid is not impressive. When working with a knife on a lawn, the effect is many times better, but to reduce the cutting height on flat lawns, instead of the native support cup, I put a smaller one from the Chinese lawn mowers. Well, actually, all the disadvantages.

Excellent machine. Once it started to stall, but cleaning the flame carrier fixed everything.

The lawn mower won’t start after winter

In such cases, the unit must be serviced. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean and rinse each unit. Blow out the filters with air. Pay attention to fuel quality and octane number.

It should be borne in mind that products of such well-known companies as STIHL, Husgvarna and other brands will not run on cheap gasoline with a low octane number.
Suitable fuel for them is from the AI ​​brand – 92 and higher from car gas stations and then from well-recommended ones, since there is also bad gasoline at gas stations. The use of high-octane and high-quality gasoline will determine how long the lawn mower will be used and how long it will last.

It is necessary to take into account one more fact that with a long storage of a diluted fuel mixture, its working qualities fall, which also leads to consequences in which the lawn mower does not start. Therefore, it should be diluted in portions, that is, the amount of the mixture that is produced at a time.
The operating instructions clearly describe and explain the mixing ratio of gasoline and oil. Strict adherence to the correct proportions will at least save you from several questions about why the lawn mower won’t start and what to do in such cases.

The lawn mower starts and stalls. What to do?

1. There is a spark, and everything seems to be normal, but the mower will not start, in such cases you should check the air inlet valve to the fuel tank. A clogged valve leads to the creation of a vacuum in the tank, in which the carburetor does not receive enough gasoline, so the lawn mower will start, but then stall. To exclude this reason, you need to clean the valve and try to start the lawn mower with the tank cap not completely twisted.
2. If this does not start the mower, remove and clean the fuel filter and check all carburetor parts, then try starting. The lawn mower will not start again, the air filter is disconnected, try to start without it, if the mower starts up, the reason is in the air filter, replace it.

The lawn mower will not start, or will start but stalls. What is the reason?

To understand this, you need to know the principle of operation of the unit as a whole. It also happens that, just bought, a new saw does not start, and it starts running around the service centers, in such cases it is recommended:

Carefully read the instruction manual;
to study in detail the method of first starting and running in lawn mowers;
try to understand how the product works;
how gasoline is pumped up and so on.

Causes of malfunctioning lawn mowers:

The quality of gasoline is poor;
incorrect proportion of gasoline and oil;
clogging of the fine filter;
the spark was gone.

The lawn mower will not start, the spark is gone

The loss of a spark entails checking the contacts and the correctness of the gap between them, the conducting wires to the candle and the candle itself.
The way to check the spark is to unscrew the candle, connect the wire to it, put the candle sideways to the motor casing and pull the starter several times as if starting the lawn mower, while looking at the coal and the contact of the candle, a spark should run between them.
If there is no spark, take a new candle, follow the same procedure, if the spark cannot be traced, then there is a problem in the wire or contacts, it is better to replace them.

Petrol trimmer won’t start well

So what to do if the petrol trimmer won’t start well or won’t start at all? The most common reason for such a breakdown is poor quality fuel. Remember that, for example, trimmers of the brands "Stihl" and "Husqvarna" are unlikely to start on fuel quality lower than AI-92. You should not save on fuel, because repair of parts of the cylinder-piston group can be one third of the total cost of the scythe, and sometimes even half. Also, when preparing the fuel mixture, it is necessary to correctly observe the proportions of fuel and oil, which are always indicated in the instructions for the trimmer.

What to do if high-quality fuel is poured into the gas tank, there is a spark, but the tool still refuses to start? It is necessary to check the condition of the candle. It is located in the center of the mower body. It must be carefully unscrewed and make sure there is no plaque on it. If there is, then carefully clean the candle from carbon deposits and dry it.

If the lawn mower does not start even after the methods suggested above, then you need to try to remove the air filter and start the device without it. If the trimmer still doesn’t work, dust off the old filter or buy a new one.

It also happens that the mower works for a maximum of 5 minutes, and then stalls and does not start until it cools down. In this case, try opening the filler cap of the gasoline filler cap – a suction sound should appear. Then screw the cap back on. If you do this manipulation while the trimmer has just started to stall, then the speed will be restored, and you can continue to work. If the mower stalls before opening the lid, then you just need to start it as expected according to the instructions.

Trimmer won’t start after winter

How to be in such a situation? Don’t worry and panic. This is a very common problem that can be solved in just 3-4 minutes. Firstly, if last year’s fuel remains in the gas tank, then it must be drained. Gasoline loses its octave properties after 2 weeks of inactivity. Secondly, you need to start a lawn mower after a long stagnation in a slightly different way. First you need to open the throttle and pump a little fuel mixture into the carburetor, then pull the handle until you feel a little resistance. Then you can start the trimmer.

Trimmer won’t start. Why?

A petrol trimmer is a surprisingly useful thing that can be used to tidy up not only a miniature lawn in the backyard of the house, but also mow a lawn of considerable size without any extra hassle. But, like all things in this world, it tends to break. In this article, we will try to figure out what to do in cases where the trimmer refuses to work.

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.

We carry out diagnostics of a candle and a candle channel

If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when started, then a flooded candle may be the cause. Here, for repairs, an ordinary spark plug wrench (probably every motorist has) and a spare candle are suitable.

  • We unscrew the candle and wipe it;
  • Dry it thoroughly (do not ignite);
  • We drain the excess fuel in the chamber through the spark plug hole and dry it;
  • We clean the old candle from carbon deposits using a file or a lady’s file;
  • We expose a gap with a distance of 1 mm (you can check with any coin);
  • We put everything back in place and try to start the trimmer.

If the candle is working, the socket where it is located is completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly damp. No matter how wonderful a spark the candle may give out, there is simply nothing to ignite in a dry chamber.

If the trimmer motor still does not start, you should exclude such a reason as the absence of a spark due to poor contact between the spark plugs and the high-voltage wire. If the connection is of good quality, but there is still no spark, most likely, your ignition unit has "flown". Here it will not be possible to do without a master, since the part is not repaired, but sold as a single unit.

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.
