How To Start A Stihl Ms 180 Saw

Chainsaws differ slightly in design features, but in most cases, the assembly principle is carried out according to two standard schemes. For many devices, the instructions contain information about the need to activate the emergency brake before starting the start-up procedure. You must first master the device of the plant and study the main ways to correct breakdowns, then a person will have the opportunity to fully operate the device. The article will discuss how to start a chainsaw.

Briefly about the launcher

The chainsaw is powered by an internal combustion engine. This is a simple device, the design of which does not have special frills. Usually it works properly even in difficult conditions.

Functioning is ensured by structural elements:

1. Carburetor engine (see carburetor adjustment).
2. Clutches of centrifugal type.
3. The ignition system, in almost all devices is contactless.
4. A carburetor that adds air to the fuel mixture.
5. Fuel system. Its standard device consists of a hose, a filter and a gas tank, but sometimes it has additional parts.
6. Starter.
7. The tire.
8. Chain (see chain oil).
9. Chain tensioner and chain brake (see how to sharpen a chain).

Step-by-step instruction

When the brake is activated, the assembly process is much slower, so everything is also safe and more comfortable you can turn on the mechanism without the use of brake equipment.

If a person is not sure of his knowledge and accuracy, then the brake on the contrary needs to be activated. With the correct sequence of actions, the device will not start, the mechanism will not make actions dangerous to humans.

1. Step 1. Before you start the benzoyl, you need to move the damper, which serves as the adjustment lever, to lower it, in comparison with the optimal position. First you need to press the button responsible for the gas supply. Only if this condition is met is the normal movement of the shutter possible to the extreme stop from the bottom. It is necessary to simultaneously move the flap and hold the throttle button. Gas is set to its standard position, and the shutter closes the carburetor, preparing the device for proper operation.

Step 2. The starter handle should be pulled, and this is done in jerks, and not with soft movements. For this action you need to use moderate force. These jerks should be continued until the start of the ignition of the chainsaw is clearly heard, which will end very quickly (will subside). After the implementation of this measure, the position of the shutter must be moved one step up.

Step 3 The starter handle twitches again then until the system starts up. When the device starts to work actively, high speed is immediately noticeable, since the throttle stick is at a high level. It must be remembered that sometimes chainsaws are delivered without a starter, then all actions with this element are issued.

Step 4. The gas button is pressed once, and then released, then the position of the damper will immediately become optimal. The speed decreases, that is, the intensity of the circuit revolutions.

Step 5. The already warmed-up chainsaw is started when the lever is in the “1” position, and then the steps are taken to turn on the device.

Step 6. To turn off the engine of the device, it is necessary to put the damper in the highest position.

In our rating of chainsaws for quality, you will find all chainsaws with the optimal price-quality ratio.

Another article will help to make your choice in favor of a particular brand of chainsaw.

Chainsaws are of Russian manufacture. low price with a fairly high quality.

1. Step 1. The ignition is turned on. To do this, move the toggle switch or move the switch to the desired location.
2. Step 2. The swap primer usually has to be pressed more than two times. Gas is poured into it, after which it will be necessary to press the device more than three times. Sometimes a chainsaw is not equipped with a primer, then you can skip this step.

Step 3. The adjustment lever responsible for the location of the shutter, need to be pulled all the way. Many chainsaws have the ability to block this element. Then it can only be moved while pressing and holding the throttle button. Some chainsaws do not have such a lock, which makes their use more comfortable. For these models, gas may not be fixed or held using automatic technology.

Step 4. You need to take the starter handle and pull it with sharp movements until the ignition is heard. It is noted by the institution and almost instantaneous shutdown of the motor. After that, the damper must be pushed back to its original position, checking its passage to the stop. Then the starter handle twitches again to the device. Before carrying out this event, you need to make sure that this is the method that will help to start the chainsaw. Some devices have a different ignition system. In order for the motor to work in them, you need to move the damper only 50%, and only when the motor starts active operation, fully extend it.

Step 5 If you purchased a fixed gas model, you need to prepare in advance for the highest engine speeds immediately after activating the device. When there is no fixation, the initial power is very low, so in most cases it has to be increased. If no action is taken, then in the latter case, the saw works for a short period of time, and then automatically stalls. If this situation occurs, you need to start the chainsaw again.

When the device stalls constantly, you need to systematically restart it (see what to do when the chainsaw stalls when you press the gas). After some time, the motor will gain momentum and will be able to maintain active work without interruptions.

Step 6. When the chainsaw is already hot, that is, it was recently in working condition, to turn it on, just move the toggle switch, thereby activate the ignition, and then pull the starter handle.

If you can not turn on and start the chainsaw

When all actions are performed in accordance with the established procedure, and the chainsaw does not start working, then there are failures in its mechanism. Typically, the cause of this phenomenon is common and easily resolved problems, such as the absence of a spark, blocking the fuel supply, or clogging of the air filter. In order to start a chainsaw, you will have to find the cause and take the necessary steps to eliminate it.

Only correct action should be taken.. If a person does not know what to do, there is no need to commit rash acts. Disassembling the device is prohibited, especially carefully handle the carburetor. You can not unscrew any screws on it, since if its device caused a breakdown, it is impossible to repair a chainsaw without professional equipment.

Lists the actions that need to be performed in a strict order. Only when moving from one event to another can you determine the exact cause of the malfunction and quickly fix it without damaging other details. Algorithm of actions performed in case of failures in the chainsaw institution:

1. First, just let the device rest. This is especially true for recently used saws. It is enough to wait no more than 10 minutes, since during this time the mechanism will cool down and, in the absence of other breakdowns, will easily start. Sometimes it happens that during an institution a candle is poured at the device. If this unpleasant property has occurred, then it is enough to wait a very short pause and repeat all the steps again to start the motor.
2. The housing cover is unscrewed from the device for removing the air filter. The winding process of the device is carried out in its absence. Sometimes the reason for the lack of ignition is that the filter is dirty. If ignition happened without it, then the reason lies precisely in this. To eliminate these troubles, it is enough to wash the filter under running, warm water and soap, then dry it. You can also replace the old item with a new one.
3. The spark plug is removed. A spark check is in progress. If it does not appear, you need to replace the old candle with a new one. Usually this helps and a spark appears, but in some cases there is no spark when replacing the mixture.

This means that the ignition unit is damaged, and the chainsaw needs professional repair. Sometimes there is a malfunction of the ignition unit in the presence of a spark, so this criterion cannot be used to eliminate the likelihood of breakage.

When a spark appears when it is impossible to make the device work, you must continue to perform the steps described below.

There are times when a spark appears, but the candle itself is moistened. This is possible if gasoline gets on it. To get rid of it, it is enough to turn the device so that the cylinder turns out to be a downward exit. Then all the excess fluid will spill out. Next, check the combustion chamber, for which it is necessary to pull the starter more than 10 times. You can try to replace a spoiled candle with moisture and then check its effectiveness. If it becomes faulty, you can replace this item with a new one. After these steps, you must again try to activate the device.

Sometimes the candle stays dry. In this case, it is necessary to draw the gas mixture into the syringe and pass it into the cylinder. After that, you should immediately try to start the device. If the reason for the long lack of response to attempts to turn on is garbage that has fallen into the carburetor, then when it is removed there should be no interference with the flow of fuel into the combustion chamber. The mechanism for successful garbage collection is determined by the flow of liquid when filling the gas mixture, so you need to fill the fuel with force, and then almost immediately try to start the device.

The silencer is removed. To do this, it is unscrewed and carefully removed so as not to deform the gasket that delimits it from the engine. It is necessary to try to complete the institution without the use of an air filter and a silencer, which helps to eliminate breakdowns in these structural elements.

For any damage on the cylinder walls, we can conclude that it will have to be repaired by professional methods or replaced with a new one. Typically, such malfunctions result from an insufficient concentration of oil in the fuel.

Conclusion

The chainsaw needs to be started following the standard instructions. If there are any problems with the operation of the device, for example, the chainsaw does not start, you need to quickly fix them or take the device to repair, and to identify malfunctions and work correctly with the chainsaw, you need to know the features of its design. To learn how to quickly turn on the device and correct breakdowns, it is enough to study the main spectrum of necessary actions and follow it.
