How To Put Gas On A Chainsaw

How to start a chainsaw

The question of how to start a chainsaw can be divided into two parts:

  • Factory according to instructions
  • What to do if you can’t start

The information from the first part will be useful to those who have lost the instructions, or those who have little information about the instructions.

The second part will tell you what to do if you did everything correctly according to the instructions, but the chainsaw still Does not start. It will also be useful for those who have a poorly started chainsaw.

2.Why the chainsaw won’t start?

If you did everything according to the instructions, and the chainsaw does not start, then something is wrong with it. Therefore, several of the most common reasons may be to blame: there is no spark; Fuel is NOT supplied; clogged air filter. So, below we offer a procedure that will help identify the reason why the chainsaw does not start.

1.We start the chainsaw according to the instructions

In different chainsaws, starting can be done in different ways. Let us examine two of the most popular mechanisms that are used to start a chainsaw that exist today. Let’s take the Stihl MS 180 and Echo CS-352ES chainsaws as an example. If you have a different brand of chainsaw, then just try to start by analogy, since most likely you have the same or similar mechanism.

Before starting the description of the starting process, I would like to note that for some chainsaws, the instructions say that before starting the chainsaw, you need to turn on the emergency stop brake. Say it’s safer. However, it is more difficult to start the chainsaw with a fixed brake, so it is better to unlock it. If you do everything wisely, then the chainsaw will not do anything to you during startup. If you are afraid that without fixing the brake the chainsaw, when you try to start it, can harm you, then it is better then NOT to take this tool at all.

So let’s start with the Stihl MS 180.

    The first thing to do before starting this chainsaw is to move the choke adjustment lever to the lower position (Fig. 1). Please note that this lever moves to the very bottom on the chainsaw only if the gas button is pressed. Therefore, hold down the gas button and move the lever down. Thus, we close the choke in the carburetor and fix the gas in the chainsaw in the pressed position.

Figure: 1
After you have done this, further, to start the chainsaw, you begin to pull the starter handle with an energetic movement, until I hear that the chainsaw tried to start and immediately stalled. After that, we move the throttle position adjustment lever into the chainsaws one step up (Fig. 2).

Figure: 2

  • In this position, pulling the starter handle again until the chainsaw starts. At the same time, if it turned out to be started, due to the fact that the throttle stick is fixed in the pressed position, it will immediately work at high speeds.
  • Then, once press and release the gas button on the chainsaw. the choke adjustment lever will automatically return to the operating position (Fig. 3), and the speed of the chainsaw will decrease. Now you can work.
  • Figure: 3

  • If you need to start a heated chainsaw, then you just need to put the lever in the position, as in fig. 3, and you can wind up.
  • To stop the engine of the chainsaw, lift the throttle adjustment lever to the upper position (Fig. 4).
  • Figure: 4

    Now let’s analyze the second second mechanism that allows you to start the chainsaw.

    • First, before trying to start, turn on the ignition, move the toggle switch or the switch of the chainsaw to the appropriate position (fig. 5).

    Then press the swap primer several times. Gasoline will be pumped into it and after that we press it 3-5 more times. If you have a chainsaw without a primer, then go to the next step.

    Now on the chainsaw, pull out the throttle position adjustment lever to the end (fig. 7). In some chainsaws, in order to start it, this lever can be pulled out only when the gas button is pressed, while the gas button itself will be fixed in the pressed position. Secondly, it is not necessary to press the gas button. True, in this case, the gas on the chainsaw is automatically fixed or NOT fixed at all.

  • Further, pulling the starter handle until the chainsaw makes an attempt to start and stalls. After that, push the throttle position adjustment lever on the chainsaw back to the stop and again pulling the starter handle until the chainsaw starts. In some cases, in order to start the chainsaw, the throttle position adjustment lever needs to be pushed in only halfway, and until the end of the slide it is needed after the chainsaw starts.
  • In chainsaws with a fixed gas, the rpm after starting is high. Where there is fixation, the speed is low. In the latter case, due to low speed, the chainsaw usually stalls after working for a short time. In this case, we DO NOT adjust anything again, we start the chainsaw and it can be like this several times until the chainsaw warms up a little and can already keep the speed and DO NOT stall.
  • To start a hot chainsaw, you just need to turn on the ignition by moving the corresponding switch, and you can pull the starter handle.
  • Procedure if your chainsaw does not start

    The first thing I would like to note, if your chainsaw does not start, no screws on the carburetor are cool. If you are NOT an expert, you still will NOT be able to set up something on your own and start the chainsaw.

    The next steps required in order to start the chainsaw, performing in the order of instructions, starting to do the action under the next number only if the previous one did not help.

    • For starters, try just leaving the chainsaw alone for 5-10 minutes. Perhaps a candle was poured into it during firing. it happens. Then try starting again according to the instructions.
    • Remove the housing cover on the chainsaw, Take out the air filter and try to start without it. If the filter is dirty, it should be washed in soapy water and dried or replaced with a new one.
    • Unscrew the spark plug into the chainsaws. Check for a spark. If sparks are present, try putting in a new candle. If the spark still does not occur, then this means that the ignition unit is damaged and the dust must be carried for repair. However, visual observation of a spark does NOT mean that the ignition unit is working properly. If there is a spark, but the chainsaw failed to start, do the following steps on the list.
    • If there is a spark, but the candle is wet, then Turn the chainsaw over to drain excess gas from the cylinder if it has accumulated there. Pull the starter 10-15 times without a spark plug to ventilate the combustion chamber. Ignite the candle and screw it back, or better, change it to a new one, if available. Try starting again according to the instructions.
    • If the candle is dry, draw one or two gas mixture cubes into the syringe and pour it into the cylinder. Try to start the chainsaw. perhaps a small speck has got into the carburetor, which prevents the fuel from entering the combustion chamber. It is quite possible that this speck will be pulled out by the stream formed after starting the chainsaw by adding fuel directly to the cylinder.
    • Unscrew the muffler and remove it, being careful NOT to spoil the gasket between the muffler and the engine. Try starting without muffler and air filter. When you remove the muffler in the chainsaw, you can inspect the piston from the inside. If there are burrs or scuffs on the walls of the cylinder or the piston, or if the ring on the piston is clamped with burrs, then you will have to be very upset, as this means that the piston is damaged or worn out. This usually happens when oil is not added to the fuel mixture. In case of such a malfunction, you will have to contact the service, and perhaps even think about buying a new chainsaw, since replacing a piston is a rather expensive operation.

    Thus, we have sorted out in this article how to start the chainsaw “according to the instructions”, as well as what to do if the chainsaw starts. We hope you find these tips helpful.

    Fitting the tire on Stihl and Husqvarna

    Chainsaw models from the manufacturer Stihl may differ during the assembly process. Step by step guide:

    • Open the wing nut, remove the chain sprocket cover. Return it on the tire all the way to the right.
    • Place the chain on the bar, starting from the top, the cutting tooth on the top side must point straight ahead.
    • Attach the assembled tire to the chainsaw, pull the structure over the sprocket. Slide the guide onto the shoulder bolt. Close the cover, hit the pins in the holes provided by the manufacturer.
    • Turn wing nut until sprocket cover is in contact with motor housing.
    • Clamp bolt back forward, drive links Must fit into bar grooves. Tightens the wing nut completely.

    At the end of work, check the tension, if the headset does not move well, adjust the tension with a nut. Apply the chain brake before starting.

    The Husqvarna saw chain installation algorithm is almost identical. The main difference is that in most models, the tension and adjustment of the position of the headset to the body is controlled not by one, but by two wing nuts. A separate adjustment lever is rarely found on the protective housing of the outer sprocket, therefore the tension should be adjusted only with bolts.

    Why did the chain fly off?

    There are several reasons why the circuit may collapse during operation. This may be due to improper tire operation or insufficient tire tension. The problem sometimes appears even with an insufficiently secured drive and driven sprocket. Determination of the cause allows you to accurately select the required repair, tools.

    How to install a bar with a chain on a chainsaw?

    Often, problems in the operation of a chainsaw arise when the tire is incorrectly installed. This can be recognized by the characteristic rattling, vibration and low performance of the saw during operation. The tire is attached to the body between the outer plate, fixing is carried out with a special bolt.

    Popularly referred to as the “engine assembly”, this part consists of a drive sprocket and locking bolts. It is not difficult to install the tire together with the saw. you need to remove all the protective covers, Unscrew the fixing bolts a third of the length and put the headset. Then tighten all the nuts tightly, turn the tensioner with a special lever.

    Loose tire

    When the chain tension is reduced, the problem is often accompanied by a weakening of the tire itself. To check its condition, you need to inspect the place between the top plate on the headset casing and the inner surface on the case. When the locking bolts are loosened, the bar begins to move, which can be seen by the characteristic vibration during sawing. With frequent use, it is recommended to regularly clamp the bolts.

    Figure 1. tire weakened

    If you decide to tighten the tire yourself, you need to find and lower the chain brake. Return the tensioning screw so that the chain fits snugly into the grooves. After that, pull back the chain in the direction of travel, if it is too tight, loosen the screw.

    How to properly put a chain on a chainsaw?

    In most chainsaw models, the chain is easy to put on the bar by unscrewing the main screw, then the links need to be placed on the drive sprocket. Before starting work, the general condition of all cutting surfaces and the guide groove and setting wheel should be inspected. Often, dirt and small chips accumulate in it, which will subsequently lead to planned repairs, deterioration of sliding. Step-by-step algorithm of work:

    • Loosen the screws securing the sprocket protection cover, usually it is tightened with a wing nut.
    • Return the tensioning sprocket to the right until it stops.
    • Will overlay links to the headset, starting at the top. Drink so that they fall into the corresponding grooves.
    • Replace the chain sprocket mount, tighten the nut. Guides Must fall into a special chute.
    • Release the chain brake, pull the chain along the mowing line to check the tension. Tighten the tensioner lever if necessary. Figure 4. Installing the chain on the chainsaw

    The setting wheel should rotate freely after installing the chainsaw chain. At the end of the work, it is imperative to lubricate all moving parts of the tool to avoid rapid wear.

    Trouble with a leading star

    Sometimes chain slack is due to drive sprocket problems. The most common situation is when it is poorly secured. Step-by-step algorithm to Twist the asterisk:

    • Remove the engine cover.
    • Remove the air filter and Unscrew the candle, put in its place a special stopper to fix the piston in an immovable position.
    • Use the angle grinder wrench to rotate the clutch disc clockwise to the highest position. Check the tightness of the sprocket, adjust its position. Figure 3. the driving star on the chainsaw

    After tightening, reassemble the chainsaw, be sure to put on the protective cover. When assembling, check that the chain fits snugly on the bar.

    How to put a chain on a chainsaw correctly: instructions, recommendations, basic methods

    The chain is an important structural element of a chainsaw. It is she who has the greatest load during work, so high-quality and systemic care is required. When using any model, it is important to know how to put on the chain correctly. Watch out for its tension. If it is not secured correctly, there is a risk of stretching and coming out of the grooves. Reduced saw performance and increased risk of injury at high power.

    The chain stretched

    Any functional changes in the chain lead to a decrease in the productivity of the tool, injury during operation.

    It should be regularly monitored so that there is no deformation of the metal and stretching of more than 1 cm.

    If such a problem still occurs, you need to purchase a new circuit or correct the old one.

    Disconnect the chain links on the machine or fix it in a vice, file off the rivets and knock them out with a bit (it is not recommended to use an angle grinder).

    Remove 1-2 links depending on the chain stretch. After that, put all the elements in place, insert the rivet and beat it off with a hammer, use a special rivet tool. It is recommended to use a welding machine for reliability. At the end of the work, grinds off excess and burrs with a thin file.

    Chain tension

    To check the tension, you must first release the brake. Then pull off the chain in the middle of the headset, normally the shanks should NOT extend more than 2/3 of the height. It is recommended to scroll it manually. it is not allowed to jam and slip too fast. If necessary, tighten the nut on the protective cap.

    Figure 5. Checking the chain tension

    Installing and checking the chain tension on the bar is an important process in the operation of any chainsaw. The work is easy to do yourself. Regular tool maintenance prevents injury and reduced productivity, even when working with dense woods.

    Tensioners

    The classic budget-class chainsaw chain tensioner is usually a threaded bolt with an adjusting component, standard or side-mounted. The chain tension is adjusted with the included wrench or screwdriver.

    expensive models are equipped with easy-to-use devices that allow you to tension the chain with one movement of the lever or turn of the adjusting disc.

    In the first case, the degree of tension is fixed with a locknut, in the second, the tire and the chain tensioner are locked in a given position by installing the cover. In both versions, reliable fixation of the chain in a given position is guaranteed, the possibility of compensating for its extension with minimal loss of working time.

    Why does the chain come off

    Many, even the most experienced users of chainsaws, have faced in their life a situation where the chain jumped off the guide bar during operation. The most common prerequisite is insufficient chain tension or wear.

    In 80% of cases, the stretched chain links slip from the teeth of the drive sprocket, and it flies out from the guide under the action of centrifugal force. Although sometimes the problem appears due to an incorrect position of the sprocket on the axis of rotation or a loose fixed saw bar on the chainsaw.

    How to install a chain on a chainsaw

    The chainsaw chain is the element that is subjected to the greatest stress and overheating. With such influences, it can break, fly off the guide rail, or simply become dull from prolonged use. For timely maintenance or replacement with a new one, you need to know how to independently remove the chain from the chainsaw and install it back. The step-by-step algorithm of THESE operations will be shown below.

    Chain tension

    To check the tension, you must first release the brake. Then pull off the chain in the middle of the headset, normally the shanks should NOT extend more than 2/3 of the height. It is recommended to scroll it manually. it is not allowed to jam and slip too fast. If necessary, tighten the nut on the protective cap.

It is recommended to use a welding machine for reliability. At the end of the work, grinds off excess and burrs with a thin file.

    What to do if the chain sags

    If the chain slack, there is a risk of injury to the operator. the saw blade could break or simply fly off the guide sprockets. Of course, modern chainsaws have safety and emergency stop systems, but these systems do not always work correctly.

    It is important NOT to install a chain with defective or damaged saw links on the chainsaw, in addition to the danger of breaking at any time, such a chain will sharpen the guide grooves of the bar, which will lead to its distortion, uneven cut and failure of the guide bar.

    Because of what the chain can sag during even short-term operation?

    • There may be problems with the guide bar. Sometimes, due to an oversight of the operator or due to severe wear on the threads of the fixing bolts at the point of attachment of the guide bar, vibration may occur, which causes a loosening of the chain tension. It is necessary to check the condition of the fixing bolts and, if necessary, replace them with new ones. When the bolts are tightened enough, these problems do not arise.
    • If you handle your chainsaw with sufficient care, any chain can wear out over time. Trying to repair it or collect one from several is a useless exercise. If the chain headset has stretched due to natural causes, then it is best to get a new one.
    • The asterisk is skewed. Sagging can occur due to the misalignment of the sprocket teeth. In this case, it would be best to contact a service center to repair and adjust the position of the guide sprocket. It is quite difficult to fix the drive sprocket in the correct position, because you will have to dismantle many small parts, remove the guide rail, and then reassemble everything in the reverse order.

    Reasons for premature failure of saw chains

    Accelerated elongation of the part occurs during the running-in phase and in the last quarter of the service life. Throughout THESE time slots, your headset needs special attention and care.

    • The reason for the rapid stretching of the saw chain can be the poor quality of the material of the budget model, the mismatch of the configuration of the crown and excessive wear of the drive sprocket, a malfunction or ineffective operation of the lubrication system.
    • The full operation of the chainsaw chain also largely depends on the condition of the tire and the drive sprocket, the quality of the chain oil and the performance of the lubrication system, the timely and competent sharpening of the edges of the cutting links.

    According to professional Sawers, the operating style of the operator and the level of operational loads affect the durability of the headset. The chains of the budgetary group are more susceptible to stretching, the more expensive branded assortment has no comments on technical and operational properties.

    How to untangle a chainsaw chain

    When removing an old chain or putting a new chain on the guide bar of the chainsaw, it can become tangled. It can also happen with careless transportation. When the chain is tangled, it folds into rings.

    Due to the lack of flexibility in the transverse direction, it is very difficult to untangle it with bare hands, because when you try to untangle a ring, a new ring is formed in another place.

    It is necessary to put the chainsaw chain on a horizontal surface and spin the rings in different directions, while pulling the blade in such a direction that the diameter of the rings increases. Sooner or later, the chain will unravel into its natural position.

    There is another way. you can rivet an equal link of the chain and straighten it, then connect it into a ring and rivet the riveted links back.

    Chain tension

    The chain of the chainsaw together with the guide bar during operation experience the greatest stress, unlike other parts of the chainsaw. Over time, it lengthens in size due to boring gaps in the connecting links. This process occurs completely with all types of chains, therefore, when using a chainsaw, it is necessary to periodically monitor the correct tension of the chain and its wear.

    Here are the chain states that depend:

    • Her life span;
    • Safety of felling or timber cutting;
    • ICE resource.

    If the chain is overtightened, the efficiency of the sawing work decreases, the motor and transmission are subjected to increased loads. The guide bar heats up a lot due to increased friction, the operating mode of the chainsaw goes into excessive consumption of the fuel mixture.

    Poorly fixed drive sprocket

    Quite widespread is the option when the leading sprocket is poorly fixed. It often detaches itself during operation. The solution to this problem is carried out as follows:

    How To Put Gas On A Chainsaw
    • The protective cover of the engine and spark plugs are removed, after which the air filter is removed.
    • The next step is to remove the spark plug, which requires a special wrench.
    • A special plug allows you to fix the piston in the desired position.
    • The clutch plate is turned with a special key until the piston position changes, which must be located on top.

    Then you can fix the sprocket in the correct position and solve the problem in question. The specified information indicates that such work is quite problematic, it is often carried out by organizations servicing chainsaws.

    How to put the chain on a chainsaw correctly

    A chainsaw can be used to perform a sufficiently large number of works. The main cutting element of such a tool is represented by a chain with different blades. Modern versions are characterized by the fact that they can be serviced independently. When cutting for a long time or if basic recommendations are not followed, the cutting edge wears out quickly. That is why it is necessary to remove and sharpen the chain, and then install it. This procedure is characterized by a fairly large number of features, in which we will talk in more detail below.

    Bus problems

    Today, the problem associated with an unreliable fixation of the tire is often encountered. It is characterized by the following features:

    • The body with the guide element is fixed with a bolt.
    • The connection is provided by two plates, one of which is located on the body, the second on that, which is designed to guide the chain at the time of operation.
    • The drive sprocket and the tire support are protected by a special casing, which eliminates the possibility of damage to the main elements.
    • When the locking bolts are loosened, the structural element in question begins to move and vibrate at the time of operation. This problem can be solved by tightening the fasteners.

    Other defects simply cannot be solved. In most cases, defects become a prerequisite for purchasing a tire and replacing it.

    How to put the chain on a chainsaw correctly: direction

    When considering how to correctly put the chain on a chainsaw, we note that the modern version of the tool has a special setting wheel. Due to it, the procedure is greatly simplified. Among its features, we note the following points:

    • Considering how to properly put the chain on the chainsaw, we note that first you need to prepare a flat surface. This eliminates the possibility of damage to the tool. After that, the main part of the tool, the bar and the chain are laid out separately.
    • The next step is to remove the protection that is designed to protect the sprocket. In most cases, it is fixed with a conventional wing nut.
    • On the tire, the sprocket turns to the right until it stops. It is in this position that the tool is installed.
    • Further, the chain is gradually superimposed on the fixing element. A fairly common question can be called which side this element is put on. The installation starts from the top, the chain turns so that the tire is on the floor. Such operations should be carried out exclusively with thick gloves, which can withstand the impact of the cutting edge. The cutter on the end face must be facing forward.
    • Both elements are worn on an asterisk.
    • The next step is to reattach the chain sprocket cover. It is important to make sure that the pin aligns with the holes. Improper fixation can cause rattling or other problems.
    • It is necessary Make sure that the guides fall into the special chute.
    • The state of the chain is checked visually after it is fixed.

    The next step is to directly check to see if the chain has been over-tightened. To do this, release the chain brake and pull it along the mowing line. Checking is carried out exclusively with special gloves.

    In general, we can say that the procedure under consideration is quite simple to execute and does not require special tools. However, maintenance of NOT all chainsaws is as easy as above.

    Why the chain flies. Find out the reasons

    When considering how to install a chain on a chainsaw, you should also pay attention to what reasons lead to its East. There are three main reasons:

    • Incorrect bus operation.
    • Malfunction of the main elements.
    • Weak retention driven sprocket.
    • Strong chain elongation.

    Each reason becomes a prerequisite for which quite a lot of difficulties arise with the use of a chainsaw.

    Circuit voltage

    Stretching can be done using two methods: fast and frontal. If stretch is used, then the installation of the chain on the chainsaw is carried out as follows:

    • The nuts are unscrewed.
    • The tire is held and lifted from the edge.
    • There is a special bolt, which is used to tension the chain.
    • The tire is lifted to eliminate the possibility of sagging of the web.

    It is quite simple to do this work, it requires a small set of tools.

    The clockwise chain tension is carried out in the case when there is not a lot of free time. The chain screw is securely fixed to eliminate the possibility of rattling at the time of operation.

    How to properly put the chain and tire on the chainsaw: assembly

    The procedure under consideration is quite simple. It is characterized by the following features:

    • First, the chain brake is released.
    • The tensioning screw is in close proximity to the tire.
    • The next step is to pull the cutter clockwise.
    • If it is difficult to move the chain, then it is necessary to loosen the fixing screw.

    Modern designs of chainsaws greatly simplify the conduct of such work. Therefore, you can do it yourself, even in the absence of Special tools.

    The chain is stretched

    If the chain is used incorrectly or for a long time, it can be very stretched. This is due to the fact that the metal can deform over time. Too much wear and tear becomes a prerequisite for purchasing a new version, but it is possible to use the old one for a short period. Rapid stretching can be avoided only if the recommendations for use are followed. To carry out the work you need:

    • A hammer.
    • Pressure.
    • Welding machine.
    • Beards.
    • Pliers.

    It is not difficult to put on a stretched version of the design, but quite a few problems arise with restoration, since the metal is characterized by increased strength. In this case, the main elements are fastened with rivets. The work is carried out as follows:

    • The product is fixed in Tesco.
    • If the work is carried out while using an angle grinder, then there is a possibility that the surface will be damaged, since this tool is difficult to control.
    • After crushing, rivets are knocked out. Do not throw it away as it can be reused.
    • Chain manufacturers DO NOT issue spare parts that are required for maintenance.
    • You can make a rivet with your own hands, but the work is quite difficult.
    • The product is divided into two parts. It should be borne in mind that the number of guides and the distance between them must remain unchanged.

    When solving a problem with a long length, do not forget that the chain is NOT too short to pull. In addition, it is not recommended to apply oil to the saw chain.

    How to install a chainsaw cutter

    After installing the chain, tighten it correctly and check the tension. Among the features of this moment, we note the following:

    • Too much tension is a prerequisite for overloading, therefore, the product may burst.
    • Insufficient tension leads to chain wear and many other problems.

    In general, we can say that there are practically no problems with fixing an unworn product.
