Frequent malfunctions of the Husqvarna 236-240 chain saw

If it is impossible to start the engine, you need to perform the following steps, following the sequence:

Check the air filter and spark plug location.

  • Check that there is gasoline in the tank.
  • Change the fuel if it has been stored for more than a month.
  • Check the fuel filter. Disconnect the hose from the carburetor and watch the trickle. If gasoline is flowing freely, the fuel filter is not clogged. If the flow rate is insufficient, clean the opening in the tank cap or the filter.
  • Clean air filter. The air filter can be removed for a test run.
  • Inspect and clean the muffler for carbon buildup.
  • Check starter for proper operation. If necessary, repair the starter (replace the pulley, spring or rope).
  • Disassemble and clean the clogged carburetor.
  • Use a tester to test the high-voltage wire for a breakage.
  • Measure the gap between the flywheel magnets and the ignition module (should be 0.2 mm).
  • Unscrew the spark plug and inspect it. Measure the gap between the electrodes with a feeler gauge (normal 0.5-0.6 mm). Determine the nature of the fault by the appearance of the electrodes. If the spark plug is dry, there is no fuel mixture. The working part covered with gasoline indicates a poor carburetor adjustment or a lack of spark. To check for spark, connect the high-voltage plug to the spark plug, place the skirt on the cylinder radiator and pull the starter cord. If there is no discharge between the electrodes, replace the spark plug. Carbon deposits on the electrodes indicate a low quality fuel mixture. Clean center and side electrodes with emery paper.
  • No compression. Cause: piston assembly is defective. Check the compression. First unscrew the spark plug. Then put a pressure gauge in the cylinder bore and use the starter cord to move the piston. The cylinder pressure indicates the condition of the cylinder-piston group (CPG). It should not be less than 8 atm. Low readings are caused by wear of the cylinder, piston, piston rings.

Why the gasoline saw goes out when I push the gas: causes and solutions

It is not uncommon for chainsaw owners to have to deal with their breakdown, and it does not matter what model of this type of equipment, since the nature of failure is almost the same for all. Well, it’s the chainsaw stalled and then what? Undoubtedly, you can include the equipment to specialized services, which will repair your “iron friend” for a fee. But, as they say: why pay more?

In the end, you can personally disassemble the tool and repair it, as the breakdown may be minor, and you’ll have to pay a lot to do so. But of course, in order to bring the tool back to life, you have to be able to understand the causes of its failure and how to fix it. So let’s learn! In this article, you can find answers to questions about situations where the tool simply throws itself after a direct touch of gas. So, let’s get started.

The main elements of a chainsaw

Before we begin to deal with breakdown problems and repair tools, let’s first find out what the chain comes from. First of all, I would like to point out that this tool belongs to the category of equipment, the operation of which depends directly on the internal combustion engine.

It is also important that chainsaws are equipped with an engine with one cylinder, and whose work is done on a fuel such as gasoline. It’s worth noting that despite the similarities to other tools, it does not have a gearbox. And it is replaced by a kind of chain single-speed gearbox, through which the movement of the chain (saw) itself is made.

In fact, the chainsaw is a fairly simple design, but this does not prevent it from being reliable, practical and able to fully provide immediate continuous and cyclic work even in quite difficult conditions. This tool consists of a huge range of certain items “vital” for proper and productive operation. This carburetor, a device for direct tensioning of the chain, a bar with a chain and other elements.

Before you buy a chainsaw, be sure to research all your options and choose the right brand of chainsaw.

To make your choice easier, we’ve made a chainsaw rating for you for reliability.

Characteristic and possible causes of failure. Fix the problem with your own hands

Chainsaws are a fairly reliable and simple design. Therefore, if you take proper care of them and deal with them based on the manufacturer’s recommendations, they fail, very rarely, and quite quickly, various types of failures are fixed. But if you are faced with such a situation and want to repair your tool yourself, without turning to professionals, read the information below.

In fact, it is impossible to unambiguously and accurately determine the reason why the tool does not start or kiosks when you press the gas, as many factors affect this. But don’t forget that starting from the fact that a chainsaw is equipped with a simple two-stroke engine, conditions such as lubrication, fuel, spark and air are important for its efficient operation.

Cylinder fuel tank

Therefore, the carburetor is directly involved in the preparation of the fuel-air mixture, the filter cleans the air from dust, the ignition and spark plug create the spark, and the lubricant is in the gasoline.

Therefore, it is necessary to look for the causes of this kind of breakdown in a sequential order, starting with simple ones and gradually moving on to complex ones. And this is an important factor in a proper repair, because the person who, without considering this, begins to do a carburetor analysis is putting the carburetor at risk. Since this kind of Device must be repaired or adjusted directly in special workshops (read about tuning the carburetor).

    The important fact is that for the trouble-free operation of the appliance, you need to treat the fuel directly. Because if such a mixture is not properly prepared, most chainsaws simply will not start. Consequently, not every owner will guess the cause of fuel failure. Therefore, to ensure that your tool always works properly, you need to use only high-quality gasoline for the mixture.

And simply use oil that is made by the manufacturer of your tool. In addition, it is important to prepare this type of mixture in an amount that you use for one or two weeks, but no more (see. Dose of gasoline and chainsaw oil).

Because otherwise excessive mixture directly in the canister will cause it to lose all of its octane properties, and this will cause significant problems with the tool.

Don’t forget that by examining the spark plug, you can get important information about the chainsaw’s failure. Because if its surface is dry, it is caused by a cylinder that is not directly feeding fuel. That’s why you should check your entire range of vision in stages. If the spark plug is in black carbon, it means that the carburetor is not working properly, that is, it is feeding a lot of fuel or pouring oil directly into the gasoline.

How, for example, the chainsaw calms down when you press the gas for a simple reason, namely a simple clogging of the direct breather.

To solve this problem, all you have to do is remove the hose (fuel) from the carburetor and pay attention to see if fuel is leaking from it. Because if the mixture flows with a full jet, it means that the baffle is not dirty, and if the opposite is the cause of the breakdown.

But if upon inspection you find that there is no damage on the piston and cylinder, in which case the cause may be covered directly in the rings (piston). For this type of inspection, you need to insert the piston into the cylinder and gently push it in with the connecting rod. If you suddenly feel backlash, then the rings need to be replaced, as they are already worn out.

Why the chainsaw does not gain momentum?

Starting is a complex, multilevel process that involves almost all the life-support systems of the saw. That is why the fact that the chainsaw loses speed, starts up irregularly and behaves reliably at idle should be viewed from different angles.

  • faulty engine. its motor life could be exhausted, and the piston rings and cylinder. worn, deformed or even corroded;
  • Failed spark plug or the coil itself. as a result, no spark is formed, necessary for ignition of the fuel-air mixture;
  • unbalanced carburetor screws, as well as a number of reasons that could put it out of order.

In this article, you can find answers to questions about situations where the tool simply shuts down after a specific push on the gas. So here we go.

The basic elements of chainsaws

Before we begin to delve into the issues of breakage and repair tools, let’s first understand what actually consists of a chainsaw. First, I would like to note that this tool belongs to the category of equipment, the work of which depends directly on the gasoline engine.

As it is important that the chainsaws are equipped with an engine that has one cylinder, and the work is done on this kind of fuel as gasoline. Chainsaw is designed for use in the characteristics of chain saw STIHL ms 180 vs. It’s important to note that while it may be similar to other machines, it has no gearbox. 2.0.1 chain saw malfunctions when I step on the gas I have a Husqvarna 240 chain saw 1.5. It is replaced by the typical chain sprocket which controls the movement of the chain itself.

In fact, the chainsaw is a fairly conventional design, but this does not prevent it from being reliable, comfortable and able to fully provide a particular smooth and cyclic work even in quite difficult criteria. Chainsaws partner 350: reasons why the engine does not start, pressing the gas stalls the chainsaw? Why does the STIHL 180 stall when you step on the gas or the throttle? This tool consists of a huge range of specific parts “vital” to its proper and productive operation. This carburetor, a specific chain tensioner, a bar complete with a chain and other elements.

Before shopping for a chain saw, be sure to research all your options and choose the brand of chain saw that’s right for you.

To make it easy for you to choose, we’ve compiled a reliability rating of chain saws.

Characteristics and possible causes of failure. Do-it-yourself troubleshooting

Chainsaws are quite reliable and lightweight designs. Because if you properly care for them and treat them according to the manufacturer’s advice, then they fail very rarely and rather quickly eliminated a variety of failures. But if you are faced with this situation and want to personally repair their own tool, without resorting to the experts, then delve into the information provided below.

In fact, uniquely and precisely can not be determined the reason why the tool does not start or stalls when you press the gas, because the reasons affecting this rather a lot. Why the STIHL 180 chain saw cuts out when you press the throttle. Description of the causes, troubleshooting methods. But we should not forget that departing from the fact that gasoline saw is armed with a regular two-stroke engine, for its effective performance are important conditions such as: lubrication, fuel, spark and air.

Gasoline tank of a chainsaw

As follows, the manufacture of fuel-air consistency is engaged specifically carburetor, the filter produces purification of air from dust, ignition unit and the plug makes the spark, and the gasoline is the lubricant.

That is why the search of the circumstances of this kind of failure should be in a sequential order, starting specifically from the light and passing evenly to the complex. And it is a fundamental factor in the correct repair, because the one man who, without thinking begins to engage in disassembly of the carburetor, leads her to the risk of. Because this kind of assembly must be repaired or adjusted directly in special workshops (read about carburetor adjustment).

    It is important to remember that in order for the tool to work flawlessly, you need to be very attentive to the fuel itself. Because if this kind of mixture is not prepared properly, most chainsaws won’t start. Why does the STIHL 180 choke on the gas or the throttle? Not every owner would think to look for the cause of their problem in the fuel. Chainsaw stalls or chokes when pressing on gas. That is why, in order for your tool to always work properly, you need to use only quality gasoline.

And also use only the oil that is made by the manufacturer of your tool. In addition, it is important to prepare this kind of mixture in the amount that you exactly use in one or two weeks, but no more (cf. Use only oil that is made by the manufacturer of your chain saw).

Because otherwise overholding the mixture directly in the canister will cause it to lose all its octane properties and cause significant problems with the tool.

Don’t forget that by inspecting the spark plug you can get considerable information about the chain saw’s malfunction. The gas spark plugs on the Husqvarna and STIHL models and when you step on the gas, the chain saw stops on the. Because if its surface is dry, the reason is the cylinder, which is not fed directly with fuel. That’s why you have to check the whole range of its supply step by step. Problems with starting and why the chain saw won’t start Why the chain saw stalls. If the spark plug is black, the carburettor is not working properly, i.e. it is either carrying too much fuel or is leaking oil directly onto the fuel.

Why does the engine stop when idling?

The first and most common cause of this malfunction is improper adjustment of the carburetor. You can adjust the idle speed yourself, for this you need to have a STIHL adjustment screwdriver, which is supplied with the unit. The adjustment hole is on the right side of the STIHL 180 on the handle and is marked with “-” and “”.

If your STIHL chain saw will go flat when idling, you can be pretty sure it has a problem with the fuel pump. normally it is an air leak in the crankcase through the sump seal, or more commonly through the crankshaft oil seal. Air suction reduces or completely stops the pulse, which is fed through special channels to the chainsaw’s fuel pump. As a result, the STIHL 180 chain saw will not get enough fuel and will stop when idling.

To make a diagnosis, you can use a special device called a vacuum gauge.

The second way to check the functionality of the oil seals is to pour gasoline into the crankcase and look at them, if the seals will leak gasoline, it means they can not provide normal pressure in the crankcase, which would make it impossible to idle. If the bearings of the crankshaft can seize while running at high rpm if the seals are leaking.

How to check the STIHL 180’s crankcase and oil seals for leaks

  • Remove the top cover.
  • Dismantle the air filter housing and carburetor.
  • Remove the chain saw handle.
  • Unscrew and remove the starter motor.
  • On the opposite side of the starter, remove the side cover and the drive sprocket.
  • A piston stopper is installed in the spark plug hole, or a piece of string from an old starter with knots tied to it is stuffed into the cylinder.
  • The flywheel and clutch are unscrewed, after which the parts are removed. It is worth knowing that the chainsaw clutch has a left-hand thread and unscrews in a clockwise direction.
  • The oil pump drive pinion is removed.

If you disassemble the STIHL MS 180 chain saw, you can see the oil seals and after that you need to fill the sump with gasoline to check for leaks. Fill the crankcase through the fuel window in the cylinder by pushing the piston up as far as possible. If you notice any leaks you must either replace the defective seals or re-seal the pan. Reassemble the STIHL 180 by following the reverse sequence of the algorithm.

Repair work

Any tool can fail after a long period of use. In a Ural chainsaw, most repairs tend to be related to malfunctioning of the motor.

Causes of improper operation may be a knocked-down carburetor settings or the natural wear and tear of its components. Wear of the piston group and, as a consequence, deterioration of the compression indicator, due to which, the saw can start badly or stall at idle speeds. Loss of power at high loads may also be a symptom of piston wear and tear.
