How to put a chain on a chainsaw: Instructions, recommendations, main methods
When considering how to put the chain on the chainsaw, we note the moment that the modern version of the tool has a special installation wheel. At the expense of it, the procedure is greatly simplified. Among its features, we note the following points:
Considering how to properly put a chain on a chainsaw, we note that first you should prepare an even surface. Due to this, the probability of damage to the tool can be excluded. After that, the main part of the tool, tire and chain is separately laid out. The next step is to remove the protection that is designed to protect the asterisk. In most cases, it is fixed using a conventional lamb nut. On the tire, the stretch asterisk turns to the right until it stops. It is in this position that the tool is installed. Then the chain is gradually superimposed on the fixing element. A fairly common issue can be called what this element is posed. Installation begins from the top, the circuit rotates so that the tire is on top. Such operations should be performed exclusively in thick gloves that can withstand the effect of the cutting edge. The cutter on the end surface should be located forward. Both elements are put on a star. The next step is to reverse the cover of the chain star lid
At the same time, it is important to ensure that the pins coincide with the holes. Incorrect fixation can cause rubbing or other problems. It is necessary to ensure that the guides get into a special gutter. Visually, the state of the circuit is checked after it is fixed.
The next step is to direct verification of whether the chain was pulled. To do this, release the chain brake and carry out its pulling along the line of movement. Check is carried out exclusively in special gloves.
In general, we can say that the procedure under consideration is quite simple to execute and special tools are not required for its implementation. However, the maintenance of not all chainsaws as indicated above.
The principle of operation of the brake
Consider the principle of operation of the brake. The design of the mechanism is simple and unpretentious. This is a purely mechanical process. Starting, the brake system switcher is the lever already mentioned by us (screen), which is a strong element on the upper front surface of the chainsaw above the silencer. The screen is just located behind the operator’s hand, almost closely, it is connected to the lid. But, since we turn the tool when working, the screen may not be on hand.
Sliding lever without a spring in a cocked state
Sliding lever without a spring in the released condition of the trigger
The sliding lever without a spring with a released turmeric is fixed by a return spring at the base of the mount and the trigger switch. When impact, tire rebound, the screen hurts, drips in the hand of the sawman and then along the chain it includes a trigger that is interconnected with the screen. In the usual position, the trigger compresses the spring (not to be confused with the return spring), and when triggered, it exacers it and fixes it with a locking latch (latch). The sliding lever that is located inside the spring, in turn, pulls the metal tape. The metal tape is located around the clutch basket (clutch drum), it delays (clamps) the drum that stops rotating. The chain of the chainsaw stops.

But the brake may not turn on from mediocre pressing on the screen. In the lower part of the screen (at the place of attachment with the lid), in the body of the lever, the inertial cargo is “introduced”, which drives the trigger due to a sharp return. Due to the inertial weight, an automatic braking process occurs. The FOCUS of the forest, for example, when the tree turns, holds the saw in an inclined (lying) position and, the screen, in this case, is not on hand, but to the side. In case of return to the resume, thanks to inertial cargo, the brake system also turns on.
How to assemble a starter on a chainsaw?
After replacing the faulty elements of the starter, the turn of its reverse assembly comes. In this case, it is necessary to observe maximum accuracy, since the slightest discrepancy can lead to a breakdown of the starting mechanism. The assembly of the node should be performed in the following sequence:
- The standard cable will need to be tucked into the factory hole of the coil. The cord, at the same time, does not need to be wrapped;
- Next, you need to insert the coil to its base place. At this stage, many newcomers make a typical error. On the surface of the coil there are 2 slots. A full.Time hook of a spiral spring should get into one of them. To do this, the coil will need to be installed in such a way that it rises tightly in its original place, and the existing hook hit exactly in the slot. The correct installation must be checked by scrolling the coil along the hour of the clock until the resistance appears;
- Then you need to install the device of lightweight launch of the chainsaw. In this case, the ledge of the latter should be located in the seizure of the installed coil;
- After that, you will need a screw and a washer to fix the device;
- Next, the second end of the cord must be tucked into a special outlet;
- At the next stage, you will need to refuel the cable into the launch handle. For this purpose, at the end of the cord, you will need to tie a medium.Sized knot. If it is too small, then the cable will slip, which is why it will quickly wrap up on the drum of the starting mechanism;
- Then you need to release the loop inside the starter. Immediately after this, the rotation of the starting mechanism during the watch arrow should begin. In this case, the cord does not need to be wrapped. Next, the coil will need to be fixed with your hand, and stretch the loop by the handle out;
- After that, you need to check the operation of the starting mechanism;
- If the knot works properly, it will remain to install it on the tool, and attach it with three screws.
Starter repair. The procedure is not complicated if you adhere to the correct procedure. As a rule, replacing the starter cord will take no more than 20 minutes. The main thing is to properly place the pulley and the drum in relation to each other. Otherwise, the trigger will not work.
How to disassemble a chainsaw
The repair of the chainsaw can only be carried out after the analysis of the tool is performed
It is necessary to do it as carefully as possible, while each part is recommended to be cleaned with a detergent and thoroughly dry. Only after that is the assembly of the tool
How to remove an asterisk
To access the asterisk of the chainsaw, you need:
- Remove the crankcase lid, chain headset and tire, and then air filter.
- Unscrew the candle instead of which insert a piston stopper.
- Unscrew the clutch clutch, after installing the puller in the hole for the universal key. This will open access to the asterisk, after which the latter can be removed.
After a faulty part was removed, with your own hands can be replaced by a sprocket.
How to replace an oil pump
Removing the oil pump occurs in the following sequence:
- Remove the chain headset, and then unscrew the bolts that fix the guide chain to the body.
- Now you need to remove the pump and divide it into two parts, then remove the gasket and put in its place a new.
If such actions did not correct the problem, then the oil pump should be replaced. All assembly actions must be performed in the reverse order.
How to put a spring on a chainsaw starter?
Place the spring in the appropriate groove is a rather difficult task. First of all, the detail will need to be twisted, returning it to the previous size. After that, it needs to be inserted into the cavity of the standard hub of the drum. To tie the spring into the starter of the chainsaw, you need to act in this order:
- The outer end of the spring used must be fixed in a special restrictive ledge. In this case, the second end using the screwdriver will need to be installed opposite the standard hole inside the lock;
- Further, the loop located on the inner end of the standard spring should be combined with the hole. To do this, it is better to use a screwdriver. At the ends of the ends, the disk will need to be lowered;
- After installation of the disk, you need to check that the dog of the factory ribbon mechanism of the chainsaw stands in its regular place. Then you can collect a ratchet in the reverse order.
To wind the spring on the starter of the chainsaw, you need to take into account all the available holes and recesses. After installation, you need to pull the spring. As soon as the weakness is eliminated, the spring will remain at several revolutions. This is necessary to support the required tension of the installed part.
Typical breakdowns and repair of the chainsaw starter
Before carrying out repairs, it is necessary to find out the reasons for the breakdown. Since the product is constantly subjected to dynamic and other types of loads, its failure is not excluded. Frequent causes of starter breakdowns are: rupture of the cable, abrasion or painting several shits of the rattle drum, damage to the spring, a crack of the pulley and others. To determine why the saw does not start, you will need to conduct an appropriate revision of the starting mechanism. Consider the main types of malfunctions, and also find out how to properly repair the product.
Replacement of the cord
The starter cord is a strong rope, which is strong enough to wear, but even its technical properties do not save it from damage. The rope, at each start of the tool, rubs against the starter cover case, which leads to gradual overwhelming and wear.
If the cord is grinding, then to replace it, you need to disassemble the case of this node. After removing the cover, it is necessary to raise the drum, but only so that it does not jump out of his seats. It is recommended to carry out such work together with a partner who will fix the spring, and you will do the replacement of the cable. The remnants of the old cable should be removed, then fixed the new product in the handle and in the frame of the drum. After that, the cable should be wound on the roller, and at the end, assemble the case.
How to replace the chainsaw starter spring
If damage to the spring is observed, which is often on Chinese instruments, then the mechanism can only be repaired by replacing it. But if its damage occurred at the place of connection, that is, the ear burst, then it can be repaired.
The repair of the spring is a heating of the destruction site up to 600 degrees, after which it is slow to cool it up to 100 degrees, in which the end is wrapped in the shape of a fragment. Thus, it will be possible to avoid loss of elasticity of the product, which will extend its service life. Although most experts simply carry out the replacement of the product with a new.
The process of replacing the spring is carried out in the following sequence:
- The clip or drum of the mechanism is originally extracted.
- A spring is located inside the drum. To dismantle it, you will need to fix its upper part, and then pull the starter handle aside.
- When the old spring is extracted, you need to install a new. In this case, it is imperative to clean the body.
- When installing a new spring, you should insert it into the starter, and then get into the groove to the groove.
- At the end of the work, you can put on the drum and install the starter cover in place.
The detailed process of replacing the spring is considered in the video:
Replacing dogs of a flywheel
If you need to replace the dogs or the answer of the flywheel, then it is also not difficult to do it. This will need to dismantle the flywheel, and then remove the dogs. You should install new dogs exclusively those that were initially (plastic or metal). This is very important, since replacing plastic dogs with metal ones will lead to an accelerated wear of the flywheel. Details of replacing dogs of the starter of the chainsaw are considered in the video below.
In conclusion, it is important to note that to repair the starter of the chainsaw, you do not need to have special skills or experience. All work can be performed independently if you treat the repair process with all responsibility. Timely conduct of the prophylactic work of the chainsaws will avoid the occurrence of breakdowns when performing work in the field.

Recommendations when replacing clutch on a chainsaw
In addition to the basic rules of work told in the previous section, it is worth remembering some nuances when replacing clutch. Use only original manufacturer details. This is the key to a long and productive work of the tool. Clutch thread on all chainsaws of any manufacturer is always the left. Before removing the coupling, carefully remove all dirt and dust from the tool so that it does not get inside. During reverse assembly, do not forget to put all small details in place, including pucks and bearings. Follow the installation of a special spring (it is not in all chainsaws). If it is not installed, oil will not be supplied to the saw tire.
With independent maintenance of clutch couplings, you need to know that:
- Several saws have a puck that is located between an asterisk and a clutch, and an asterisk and a motor. Consider this when repairing;
- The special firing of the oil pump drive should not be damaged during disassembly, and is also subject to return to the original position. Otherwise, the chain will not receive a lubricant or even cease to be lubricated.
The tool that has visited the repair must undergo a check for the reliability of bolted screeds, the supply of lubrication to the circuit and the serviceability of the motor (it should smoothly turn on and work smoothly). Only after that can it be operated.
Fastening of the tire of the chainsaw
Working with a faulty tire is unsafe. Therefore, at the first signs of the canvas breakdown, you need to turn off the motor and find out what’s the matter. Knowing the constructive features of the tire and its fastening on your chainsaw will help successfully eliminate the cause of the malfunction.

The tire determines the axis and length of the cut, directing the chain. But the basis of the mechanism is still mounting. It is installed in the groove between the internal plate on the motor body and the outer plate located on the chain headset casing. The tire and casing are fixed using a bolt connection. This part of the mount is called the “engine knot”, and its shape and design depend on the chainsaw model. Tire fastening and leading stars are closed with a separate lid.
The leading links of the saw chain are installed in the guide groove on the edge of the tire and are brought into the hook with the leading star connected to the power of power selection. When weakening fixing bolts, the tire can move. The tension of the chain can be adjusted manually or, as on professional chainsaws, automatically. Finally, in the front of the tire mount there is an emphasis. It serves to reliable fixation of the axis of the cut when contacting a moving circuit with a tree.

The working tire should provide normal chain tension. To check it, you need to release the chain brake and pull the chain with your hand in the direction of its movement. If the chain does not move, then the fastening is too tight. It needs to be slightly released, after which the free stroke of the chain is again checked.

Operation of a chainsaw
The proper operation of any tool should ensure the effectiveness of its work, the safety of the working and the safety of the tool itself. The characteristics of the chainsaws include their high potential injuries. Therefore, safety requirements for chainsaws are one of the main components in the rules of their operation.
The finished one is considered such a chainsaw, which has:
- All nodes and mechanisms are working;
- A sharp, correctly stretched chain is installed;
- Fuel and oil tanks are refuel;
- The carburetor is adjusted.
Proper maintenance of the chainsaws involves the timely implementation of all operations that ensure the maintenance of the tool in good condition. The main ones include: cleaning of air filters, adjusting the carburetor, cleaning the spark plug and adjusting the gap between its electrodes, sharpening the circuit and replacing fast.Intake parts.
The new chainsaw requires running for 40-50 minutes at low speeds, after which the chainsaw is turned off and the chain tension is also checked. Then you need to make several cuts, applying weak effort, and only then can you work in normal mode.
Setting the circuit and adjusting its tension
When using a traditional linear mechanism, it is necessary to remove the chain star lid (1), unscrewing the nut (2).
At the same time, it is important to remember that before each installation or dismantling the protective cover of the chain stars, it is necessary to loosen the chain brake, for which it is necessary to pull the emphasis (1) (see. Photo below) in the direction of the handle (2).
The pin (1), part of the tire hole, should be shifted to the groove in the extreme left position. This is done using a tension screw (2).

The chain is started for clutch (1), put on the leading star and put on the bus. At the same time, attention is paid to the location of the cutting edge of the tooth. On the upper branch of the chain it should be directed forward. The chain should be easily stretched, the clutch drum should rotate when the chain is advanced.
Then, with a rotation of the stretch screw (1), the bus moves forward until the lower branch of the chain enters the groove of the tire and packs its lower. The final adjustment of the chain tension and the tire tightening is carried out after installing the lid in place and preliminary (not to the end) tightening of the mounting screws.
For greater convenience, the chain tension screw can be located on the side.
Correctly stretched circuit should not sag from below and have too strong tension. The first is controlled visually, the second. Stretching the chain along the shine with the hand. The latest operation to avoid cut should be carried out in the mittens. If the lower branch adjacent to the lower edge of the tire, and the chain is freely extends with the hand, then its tension corresponds to the norm.
When checking the tension of the circuit, the brake of the chain, if it accidentally fixed the chain, must be released. The chain tension should be checked often. New chains tend to lengthen while using.
During sawing, the chain is heated and lengthens due to friction. The tension of the chain is weakened and the chain on the bottom of the tire sags. If the work is performed at very low outdoor temperatures, then the circuit heated to operating temperature sags so much that it should be tightened. If the work of the chainsaw is interrupted, then the chain must be immediately loosened, otherwise when cooling to the ambient temperature, the chain will stretch too much. As a result, a chain can occur, as well as damage to the crankshaft and bearings.
The maintenance of the chain consists in its periodic examinations, timely sharpening, replacement when the marginal wear or other defect is detected, which prevents the safe and efficient operation of the chain. How to hide the chain read in the article Sharpening of a chainsaw.
Each mobile part in the first commissioning requires some time for grinding. Despite thorough processing, each surface has microscopic roughnesses, which are smoothed out during grinding. For new circuits, the operation time is approximately three minutes. The engine should operate without load (do not saw) with half the supply of fuel mixture. During this time, the surfaces of the details of the chain are smoothed out and the material settles, the chain sags, and must be tightened. When developing friction force, it is especially large, so it is important to ensure sufficient lubrication of the chain.
Gas station refueling
Oils for the engine and circuit are sold in the same place where the chainsaws.
Dilution of oil in gasoline is performed in a certain sequence. First, oil is poured into the container (canister), then suitable gasoline for the chainsaw is added to it. In the volume that makes up about half the total amount of the required amount. After thorough mixing, the second part is added. Before pouring the mixture into the fuel tank, it shakes up thoroughly again. The bay should be produced carefully, without straits. Do not pour fuel to the very top of the tank, it is necessary to leave a small free space at the top. The volume of fuel tanks of chainsaws is usually about 0.5 liters, and at a power of a chainsaw 2 kW (2.7 l.With.) and with fuel consumption about 1.2 l/h, this volume is enough for about 30-40 minutes. Work in maximum load mode. Less powerful chainsaws have the volume of the fuel tank usually smaller.
For lubrication of chains, manufacturers of chainsaws recommend using special oils they sell, containing adhesive additives that provide oil retention on the chain. Operationsmen often replace them with other. Transmissive or motor. Oil is poured into the tank simultaneously with the gas station.
The ratio of tanks for fuel and oil is selected in such a way that with the full production of fuel, there is still a little oil in the oil tank. At the same time, you should know that the fuel consumption of the chainsaw. Above) depends on the correct adjustment of the carburetor. If the latter is adjusted incorrectly, the fuel can end much faster than the oil for the chain.
If during operation the amount of oil does not decrease or decreases too slowly, this indicates that the lubrication of the chain of the ribbon is disturbed-due to a decrease in the conduction of the channels through which the oil is brought to the tire, or malfunction of the pump. It is necessary to determine and eliminate the malfunction. The performance of some pumps can change manually using a adjusting screw.
