Husqvarna 128r Trimmer Won'T Start

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

Description and characteristics of the petrol brush 128R

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 brushcutter 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 help the tool turn on quickly even after a long period of inactivity, it has a built-in primer for priming fuel and a Smart Start system. The maximum working width is 45 cm. The Husqvarna 128R Petrol Brush Cutter is a petrol trimmer with a straight bar and professional handles made in the shape of a bicycle. 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 the brushcutters.

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 brushcutter to be used for long periods of 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 petrol cutter, it is enough to gently pull the cord, since 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 petrol cutter 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.

Do-it-yourself repairs to Husqvarna petrol cutters, 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 faults on the Husqvarna 128R brushcutter are ignition or fuel supply 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 Husqvarna 128R petrol cutters fully corresponds to its quality and performance.

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 brushcutter: it is the design of the clutch, like a chainsaw, allows for gas overloading 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: Fastening the handle bar to the bar will force it to be remade immediately 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 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 this is the growth of the mower, its maximum height is 180-182 cm. With a greater height and with proper 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 several 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 brushcutter. Well, actually, all the disadvantages.

Husqvarna is a Swedish company that is a world leader in the production of various garden tools. Husqvarna brand products are trusted by customers all over the world.

One of the most popular trimmer models is the Husqvarna 128r.

It is a lightweight lawnmower designed to keep small backyards clean.

One of the main design features of Husqvarna brushcutters is its low weight. The trimmer weighs only 5 kilograms.

This moment is very important for future owners, as the lawnmower is carried on the shoulders, and fatigue sets in over time.

Application features

Before each start of work, make sure that the tool is in good working order and that there is a fuel mixture.

Care must be taken when mowing the grass, as the knives rotate at high speed and there is a high probability of stones and other solid objects flying off at a distance.

Service

The Husqvarna 128r trimmer does not run on clean fuel, but on mixture. To prepare it, you must use gasoline and branded oil from the manufacturer.

It has been specially developed for gardening tools to prevent piston deposits from forming, significantly extending service life.

Mix oil and gasoline at a ratio of 1:50.

Advantages and disadvantages

This model has earned great consumer confidence due to its high technical characteristics and a long period of operation.

To summarize, let’s highlight the advantages and disadvantages of this model:

  • Low consumption of fuels and lubricants;
  • Weak vibration;
  • Light weight;
  • Easy on-site repairs and troubleshooting.
  • With prolonged use, there is a significant load on the spine;
  • The standard length of the belt is designed for tall people.

Breather and exhaust port

Often, delicate branded petrol brushes do 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, preventing 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.

Diagnostics of filters for petrol cutters

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 brushcutter stalls when starting, then a flooded candle may be the cause. Here, for repairs, an ordinary candle wrench is suitable (every motorist probably has) and a spare candle.

  • 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 petrol cutter 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 good and 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.

Complex reasons for the failure of petrol cutters

If the step-by-step troubleshooting algorithm does not work, and your scythe still does not start or stalls, it is worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for erratic tool performance. There are three main problems here:

  • Clogged ducts or nozzles. All this is cleaned by special washes or blown by a powerful jet of compressed air from the compressor. Do not use needles and wires, as the bore may be damaged;
  • Worn carburetor gasket. Exit replacement of a failed gasket;
  • Violation of tightness. To check this indicator, you can use an ordinary household tonometer, replacing it with a suitable pressure gauge. Watch the readings: if they do not change everything is fine, but if the pressure starts to drop, then some part of the carburetor is faulty. We’ll have to find it and replace it with a new one.

If everything is in order with the carburetor, then the petrol trimmer may not start due to wear of the piston group. If chips, scratches or scuffs are found, the piston or cylinder should be replaced. Piston rings are subject to mandatory checks. A small backlash of the piston when rocking the connecting rod indicates that it is time to change the rings. It is best to entrust this procedure to the specialists of the service center.

Why the petrol cutter won’t start troubleshooting

Caring for the personal plot, summer residents periodically encounter the fact that the petrol cutter does not start. There are many reasons for tool failure. For the correct diagnosis of the problem, the owner of a useful unit in the country needs to know the device and the principle of operation of its individual parts.

  • How to start diagnostics of brushcutters
  • Checking the fuel mixture
  • We carry out diagnostics of a candle and a candle channel
  • Diagnostics of filters for petrol cutters
  • Breather and exhaust port
  • Complex reasons for the failure of petrol cutters
  • Rules for the operation and storage of petrol cutters

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.

The owners of Calm envy

I have been using the trimmer for 4 years. There is an easy start system, so you don’t need to put all your strength into a jerk. As soon as you feel the resistance of the cord, a smooth jerk, and it starts up. In order for the mower to work for a long time, the proportions of the fuel mixture must be observed. I use 20g of Husqvarna branded 2-stroke oil per 92 liter of gasoline. You can store the diluted mixture for no more than two weeks. When storing for a long time, you need to drain all the oil, run it on an empty tank to use up fuel residues. I recommend working at full power, then the mixture completely burns out without forming carbon deposits in the exhaust pipe and inside the engine.

Easy start-up, minimal vibration

I have little experience with the trimmer for just one day. But there are already impressions. I started pulling so gently a couple of times with the shutter closed, which is advised according to the instructions. On one full tank I mowed a ten-meter track 2 meters wide and a square clearing 5 to 5. I consider the flow rate normal. Filled in 92 gasoline and branded oil for two-stroke engines. I liked the suspension system, even into space! The belts are durable. I set it up for myself in three minutes. So far I have tried only fishing line, coped with the grass. I hope that further exploitation will give a new experience, which I will share.

Fuel pumping, easy start

The trimmer was presented to me, so I use what I have. Plot for processing 13 acres. The first time I mowed weeds with a disc, now I manage with a fishing line, because I don’t start. I do not use it often 3-4 times a season, but I am very glad that I have this thing, because it saves time enormously. Now I myself would buy such a trimmer.

Lightweight and easy to operate. Everything is very clearly described in the instructions. You can work all day. The cutting equipment is changed within five minutes.

The flexible shaft is unusual at first, but then you realize how convenient it is.
