No chain lubrication on STIHL chain saw 180

The chain lubrication system of a modern STIHL chainsaw

One of the most important chainsaw systems you can’t work without is the chain lubrication system. It’s no secret that chain rubs against the bar when the chain saw is in motion, causing heat and early wear. Chain lubrication is essential for reducing friction.

Chain lubrication system for chain saws

To supply oil for chainsaw chain lubrication, the tool uses a special pump that doses lubricant to the saw bar depending on the number of engine revolutions.

The system uses chain lubricating oil with high adhesive properties to evenly distribute the oil around the bar and keep it on the bar even at high chain rotation speed. Oil is leaking, chainsaw output is in the place where the chain tension bolt goes. Let’s take a closer look at the oil supply system implemented in modern chainsaws.

The structure of the pump, lubrication system and principle of operation

The oil pump drive consists of two parts, a plastic pinion with a worm gear and a wire lever that transmits power from the sprocket drum to the worm gear.

One of the main faults of the saw’s oil system is defective threads on the plastic pinion of the oil actuator, so whenever possible, you should check its wear and thread quality.

The lever is rigidly attached to the pinion, and they are supplied as one part. The tip of the wire lever has a characteristic bend, which is designed for better grip with the drive sprocket drum. There is a special slot on the drum to mount the actuator.

The STIHL oil pump 180 is a metal pump that cannot be dismantled. The pump housing has an oil inlet and a channel through which the oil from the oil connection flows directly to the pump. The mechanism is fitted into the housing of the STIHL 180 chain saw.

When the engine speed is increased, the sprocket bar starts to rotate the worm gear pinion behind the wire lever, which in turn makes the oil pump plunger turn, and as a result the oil is pumped through the oil channels to the chain saw bar.

The oil pipe of the chain saw is directly involved in the system and has an oil sump at the end. The oil receiver is also a filter. On the other side of the oil pipe there is a rubber hose extension whereby the hose is fitted on the housing of the STIHL 180 chain saw straight after the oil pump.

Troubleshooting and repair of the STIHL 180 chain saw

A common type of chainsaw is a chainsaw. Such a device is widely used in construction work, cutting firewood and other various operations with wood. But no matter how good the tool is, malfunctions can occur in its operation. STIHL 180″ chain saw repair is more profitable to perform yourself, as it will not only save money, but also help to understand her device.

As you know, nothing in this world is everlasting, and over time everything has to be repaired. Here and the oil system STIHL ms 180 is no exception, and has its own specific faults. Let’s take a closer look at them.

Signs of failure of the lubrication system, the following:

  • the chainsaw chain is completely dry and not shiny;
  • Oil won’t come out of the oil tank;
  • the chain quickly stretches and this happens all the time;
  • the saw bar moves sideways when sawing;
  • the guide bar is getting hot and in the chainwheel area, the paint is melting.

All of these signs, directly or indirectly, point to problems in the chainsaw’s chain lubrication system.

The first thing to do after you suspect that the chain oil is not coming is to check the oil feed. There are two ways to do this. The first one is described in detail in the instruction manual of the tool and consists in starting up the chainsaw, increasing the throttle as much as possible and pointing it towards some obstacle.

If it is working, oil will run off the bar tip and a streak of oil droplets will appear on the surface where the bar is facing. If there is still a fault in the system, the surface will remain clean.

The second way is to remove the bar from the chainsaw and start it. When the engine speed increases, at the place where the bar shank is installed, oil will flow from the oil channel, if this does not happen, it is necessary to look for the cause of the malfunction.

Diagnose

Begin by inspecting and checking the STIHL 180 oil sump (filter). As a rule, if the filter is badly soiled, the oil supply may be cut off.

To save money, a clogged filter, you can try to clean it by washing it well in gasoline.

Next, it is necessary to remove the sprocket drum, and check the condition of the drive pinion. The threads on it should be well pronounced, not nicked or have any other defects, also with the gear removed, you should check the wire lever. It must crimp the pinion tightly and not rotate, otherwise the pinion stands in place and does not transmit the force to the pump, and as a result the oil supply is stopped.

If all of the above methods to find and eliminate malfunctions did not give results, it is necessary to apply extreme measures, i.e. е. disassemble the pump.

How to Remove a Pump

Oil pump is installed on the right side of the bottom of the housing and the oil pipe from the gasoline tank is connected to it in the same place. To remove the pump you need to first loosen the saw from the handle, to do this unscrew the back handle of the unit and disconnect the throttle control rod. In the next step, it is necessary to take out plugs of handle shock absorbers and using a strong slotted screwdriver, press them out of their seats on the handle.

After removing the handle and folding the handle upside down the chain saw body. The hose running from the oil tank to the pump is immediately visible. It should be removed from its seat.

The pump itself is removed by means of a screw with M5 thread and a wide washer. The screw should be about 45-50 mm long. The washer is put on the screw and it is screwed into the pump (pump is threaded on the inside). Next, as the screw is screwed in, a stop made from a washer will force the oil pump up the threads. This is how the pump is removed from its seat. Before we start, we recommend that you read about how to disassemble the STIHL 180.

For a better understanding of how to remove the pump, you can watch the video below. In the video the master shows in detail how to remove the oil pump from a chainsaw, and describes the main faults in the feeding system.

The STIHL oil pump 180 is a high-quality and reliable part, so it should be replaced only as a last resort when all other system components have been checked.

Clean and flush the pump after you have removed it. A major problem with the oil pump is usually blockage. After removing it, the pump can be reinstalled.

Pump only needs to be replaced if blockage cannot be cleared.

The cause of oil leakage on the bottom of the chainsaw

STIHL 180 chain saw has a typical problem in that the oil hose is not properly sealed in the chain saw housing and leaks in the hose. To fix it, you need only remove the STIHL MS 180 saw handle, disconnect the hose, wash and degrease the seat in the housing and the hose shank, then apply sealant and put the hose back on. This simple procedure will take care of the problem and the oil will stop flowing.

Lubrication system design

Depending on the brand of chainsaw, the details of the lubrication system may vary slightly in design, but their total number and connection scheme remains the same.

The main components of the lubrication system, are:

    oil tank usually located in the engine crankcase.

STIHL semi-synthetic chain oil

STIHL chain oil for chain saws is an environmentally-friendly lubricant, because it is manufactured from high-quality virgin rapeseed. The oil does not contain any impurities that can contaminate the environment. The use of the product is an option in all climatic conditions, and it will be equally effective even at low temperatures.

STIHL chainsaw chain oil is distinguished by its environmentally friendly lubrication because it is made from virgin, high-quality raffinates. The oil does not contain any impurities that could contaminate the environment. It can be used in all climates and will behave equally well even at low temperatures.

What is the oil and how to lubricate the chain

High quality oil

Absolutely every chainsaw is equipped with a two-stroke carburetor engine, as well as in its “arsenal” there are two tanks. the first of which is designed for gasoline, and the second is used for oil. The main distinguishing feature, which has oil, designed specifically for this kind of engines, is directly that you need to systematically add oil to the gasoline. And this should be taken very seriously, as your negligence can lead to tool failure.

In order to choose the right oil for chainsaw chain lubrication, it is necessary to take into account the zoning, which should be minimal, how smoky the oil is, and it is also important that it should not be the cause of coking of the exhaust and bypass systems.

In addition, it must withstand low temperatures without freezing, for example, this feature is felt when it is necessary to work in the fall or winter.

The viscosity of chain oil for a chainsaw chain should be optimal for optimum performance. It must also prevent fouling of the spark plugs when the chain saw is in operation. To keep the engine as clean as possible and to “protect” the moving parts from wear and tear as much as possible.

Design and repair of the chainsaw oil pump

Any chainsaw, regardless of its class, power and other technical characteristics has besides other main functional units the lubrication system. There is an oil pump responsible for pumping the consumable to the saw headset for its lubrication and to reduce the wear of the cutting element (wear is inevitable due to the friction force).

This important assembly can break down, which is why the operators of the power unit have to diagnose the breakdown accurately, and then, to repair the oil pump of the chainsaw. The latter is realistic to do on your own without having to go to a service center.

Diagnostics and correct chainmachine maintenance

The performance of the chainsaw depends on a number of reasons:

While the amount of tension influences the performance of the chainsaw, the sharpening of its teeth influences the cutting speed. So it is important to pay a lot of attention to sharpening. With a good sharpening teeth sawing is even more effective, more accurate and safer.

The regularity of sharpening procedures has no special standards, but profesional operators advise to do it a couple of times a day. This is because the teeth dull quite quickly when making heavy cuts.

In most cases, the degree of blunting the chain is determined by the performance of the chain saw. Not only that, the tool also needs sharpening when the guide bar starts to run to the side. Another measure of dullness is the condition of the chips. Usually, correctly sharpened teeth make a homogeneous chip. If the chain on a chainsaw is stretched and how to reduce it the chain on a chainsaw. In all these cases the chips are rectangular or square. In the case of a blunted chain, dust will dominate the shavings, and the sawdust will resemble the shape of a needle from a regular hacksaw.

If you often check the tension in the chain and sharpen it in time, the chain saw will last a long time. And even hard wood is safe for sawing.

In case of lack of experience it is advised to call in a specialist. For maximum effect, how to clean the carburetor on a chainsaw. How to tension the chain on your chainsaw quickly and correctly. Professional lumberjacks recognize the condition of the chainsaw and its components upon first inspection. How to tension a chain on. fb.For more information see. They will determine how worn it is, how tight the chain is, and the sharpness of the teeth.

Regardless of chainsaw class or application, the cutting attachment consists of a guide bar and a tensioning device. The manual has information on how to tension the chain on the chainsaw correctly so that the engine is not overloaded and the wear on the cutting attachment is eliminated.

This element of the saw mechanism is used in conditions of high alternating loads and therefore requires constant monitoring during operation. A characteristic feature of the saw chains in operation is the increase in size due to gaps in the link joints.

Accelerated elongation of the part occurs during and in the last quarter of its service life. During these time intervals the harness needs special attention and careful maintenance.

  • The reason for the rapid stretching of the saw chain can be poor material quality of the budget model, mismatch in the configuration of the crown and excessive wear on the drive sprocket, a faulty or ineffective lubrication system.
  • To a large extent, chain saw chain performance also depends on the condition of the bar and drive sprocket, the quality and performance of the lubrication system, the timely and correct sharpening of the cutting edges.

According to the judgment of professional sawyers, the operator’s working style and the level of use influence the durability of the chain headset. The chains of the budget group are exposed to a greater extent to stretching, more expensive brand-name assortment has no remarks concerning technical and working qualities.

How to tension the chain on a STIHL chain saw

Any experienced chain saw operator who knows what he is doing has to check the chain tension and sharpen the chain teeth before starting work. If you don’t pay attention to the condition of the tool, its performance in the process of work is very reduced.

Proper chain tensioning will extend the life of the chainsaw chain and keep it from slipping off the guide bar when you’re sawing.

Chain tension plays the most important role in a chainsaw’s function. If it is not properly tensioned, it can simply get damaged or slip off the guide bar while you are sawing. How to tension the chain on a Husqvarna 142 chain saw. On the contrary, if the tension is too weak, the pressure on the engine increases. This would shorten the life of the chainsaw significantly, as it begins to wear out even more quickly. The chainsaw chain has another important function: it keeps the bar from slipping sideways when idling.

How the tensioning procedure works?

To check the tension in the chain, pull the chain up by grasping the notch in the middle or last part on the outside bar. What to do if the chain on a chainsaw is stretched and how to. How to remove and replace on how to remove and replace on a chainsaw also the sprocket. If the tension is correct, the saw will have 1/3 of its tail in the guide bar groove. If you exceed this limit the tension in the chain is too high and if you do not exceed it, the tension is too low. Free movement of the chain on the bar is important. How to put a chain on how to tension correctly chain replacement on a chainsaw. This is easy to check by trying it out with your hand.

the tensioning process is easy, just understand the order of all the steps and be very attentive to this procedure.

Before you start you must make sure that the saw is not running and that accidental starting is out of the question. Wearing protective gloves, you must rotate the chain by hand movement on its axis. If it is too loose, there is a big slack in the back of the bar. It is worth looking at this factor to see if the chain saw needs adjustment before use.

First it will be necessary to look at the tensioning mechanism, located to the right under the side cover that fixes the axle of the tool. In most cases, this mechanism is a simple bolt, but in some cases chainsaws are equipped with a special tensioning system, where no additional devices are required.

The peculiarity of independent troubleshooting

Fully independent repair of chain lubrication of a chainsaw, all things being equal, requires knowledge of the interaction of all elements of the system, the availability of tools and locksmith skills.

Many chainsaws can be repaired with partial or complete removal of all accessories. To perform complex repairs, it is better to use the capabilities and technical potential of service shops.

Parts with chopped threads, damaged splines or loose threads in the lubrication system of the STIHL chain saw 180 and other models of the same type should be replaced.

If there is no oil flow to the headset structure when the tank is primed, the cause should be sought in the pump itself. Dismantling and disassembling the mechanism will help you find the defective parts and fix the problem by replacing them.

STIHL STIHL 180 chain saw chain is not lubricated

STIHL MC 180 chain saw and what to do about it

STIHL chain saw MS 180 in operation. The problem is as follows. Before winter storage, on the advice of the mechanics, I put 4 drops of engine oil (STIHL) in the hole in the plug. Screwed the spark plug in. Chain for chain saw STIHL ms 180 from 10 Company Ip Savitsky A. By bizorg.su, ID 1109322. At the moment I was about to go to the cottage, decided to take a look at the saw. I pulled the starter, but it does not turn! Unscrewed the spark plug, it was covered in oil, wiped and put it back. same. Unscrewed, cranked the starter with no spark plug. everything spins perfectly. Screwed it back in. the starter does not turn. What can be?

Flush your chainsaw with unstained, not diluted gasoline, pour it straight through the spark plug hole and slowly crank the starter motor. Later, drain the fuel and use the newest. After all this work, dry the saw and the spark plug, and only then try to start it. Learn how to re-condition, not just pull and go.

Tell me why the starter motor might be stuck? STIHL chain saw 180 brand-new.

If you don’t take it apart you won’t know. Maybe the starter cord doesn’t fit properly, or maybe there’s a drain somewhere in the way. STIHL chain saw starter gears are rugged and built to last. Any illnesses are not observed constructive plan, in the main or mud, or saturated use. If your chain saw is new, take it to a service center, it will be repaired under warranty.

I’ve noticed with my own STIHL MS 180 chainsaw that when the tank is empty the idle speed increases and the chain starts to turn even when the trigger is released. If you press the gas button, the chain saw stops. It goes on like this for about 10 seconds, then the saw stops. I have not seen such a phenomenon in automobiles, that when there is a shortage of fuel in the carburetor engine speed increases. Why does this happen?

It’s a common thing with two-stroke engines. With less gasoline in the carburetor the consistency is depleted. As a consequence. RPM increase, acceleration decrease. Accompanying this is a short-term overheating of the cylinder head. It won’t kill the engine, but it won’t make it healthier. It is necessary to avoid to run out of fuel to the end of the tank.

I have a STIHL MS180 chain-saw, it’s used for country-side season to cut firewood. In the near future the chain does not respond when throttle up, the chain does not turn at all or jerks. Unreal to saw. What can be the problem??

For a brand-new chain and sprocket, the tension has to be exactly as per the manual. Make sure the lower branch doesn’t sag. and the upper one could be taken out with the fingers to the height of the leading link. Then the chain will run quite freely on the bar. But the sprocket teeth are gradually wearing down, reducing its pitch. And the gradual stretching of the chain increases its pitch. and there comes the time when the steps of the same sprocket and the chain stop coinciding to the extent that the recommended tensioning already causes the chain to be difficult to move. In this case we advise to reduce the tension a little. Right up to the point where there’s a certain amount of slack in the lower strand. By the way, it is recommended to use a couple or even three chains on a sprocket for the same reason. In this case the wear is moderate and there is no accelerated wear of the new chain on the old, partially worn sprocket.

The STIHL 180 chain saw has a tendency to bang on the throttle after starting and stops when you start cutting. But if you gas it for about 30-40 seconds it starts running fine. used up 3l of gas, filters untouched, dealer oil.

If it started not so long ago, it is likely that something got into the carburetor with the bad fuel. Needs to be cleaned.

I would like to buy this unit. What is necessary to pay attention to during examination?

Not to mention the engine itself, as it is better diagnosed in the service, you can look at the rest and get a lot of information. A significant amount of mileage can be seen in the following: The top cover latch is loose. A worn sprocket on a chain saw should be new (It should lock tightly and not turn from vibration). A new chain sprocket on a worn out saw. If you can’t get any oil in the chain saw while it is running, then you need to look for the problem. With the lid off, the motor is moving relative to the housing. Cut chain catcher and chain damage on the chainwheel cover. You can also take a closer look at the carburetor on the left side. Where the wire rope enters the choke axle lever. A chain saw that’s been running a little will have a smooth, oblong sprocket. The longer the saw has been in operation, the more this hole will be worn out. Occasionally the chain rubs up and down. Under no circumstances should you take a saw that has even a small amount of play on the right end of the crankshaft relative to the motor. This is a sign of impending repairs.

If the chain still rotates, the engine speed is too high. It should be understood that the normally adjusted and serviceable motor is completely likely a few overstated idle stroke immediately after start-up to warm up. And it can be raised decently. before the chain turns. As the engine warms up the idle speed goes down little by little. For this reason it is recommended to adjust the idle speed only when the engine is warm.

Would it be possible to fit the STIHL MS 180 chain saw with a clutch drum with removable ring (it would be a “modernization” of the drum allowed), for example on the 250?

You can do it at. Everything fits just fine. Just don’t run over to 325″. It’s hard on the motor. But there’s a couple of things to consider. The sprocket on this set (with the detachable one) is a little bit bigger by the cross section and one tooth more. Your chain speed would increase by a ratio of 6:7 and therefore the engine load would also increase. But practice showed that it is not critical with normally sharpened chains. And 2nd. A brand-new 50-piece chain is hard to put on a sprocket like that. (In general, 51 links are recommended, but they are rarely available). The first time you have to struggle to get it to fit the sprocket and the tire. And later, when a little bit stretched, it will be all right to wear.

Let’s talk about the oil flow device directly on the chain

Mainly want to put the Accent on the fact that remains to do our customer chainsaws manufacturer STIHL have a fairly small size but, nevertheless, they are very massive. These features attract future buyers of this kind of equipment to the models of this company. In addition, you can easily and simply create a variety of manipulations with this device regarding work with wood species (see. how to cut a tree).

STIHL chain saw 180 oil flow adjustment.

STIHL chain saws also have a high cutting power. What’s more, the machine is equipped with the latest accessories (see STIHL chain saw.The attachment for chain saw angle grinder) additional thanks to what contribute to the convenience and ease of work. But actually let’s talk directly about the device that the manufacturer has equipped its chainsaws. The STIHL chain saw chain lubrication system thus consists of

It is worth noting that the direct oil supply through the work of the pump has a special regulation. An important fact is that the chain is lubricated for the chain as long as the chain saw is in use. It is for this reason this part serves its owner for a long time enough.

Undoubtedly, the chain must be systematically lubricated during operation, so the oil for its direct lubrication must flow to its surface continuously. As this is the whole direct design of the tool.

During the operation of the device, oil directly starts to come out of the bar groove and is immediately absorbed by the sawdust.

That’s why the process of lubricating the chain area itself is automatic. But it’s worth noting that there are such models, which have the so-called “dosage” of oil, which should be fed directly to the chain. And of course the model, which price range is quite low, have only a hand pump working directly through the action of the drive, which is located on the handle.

Lubrication System Failures and How To Fix Them

The main faults of the oil supply system on the chainsaw can be divided into two main types, these are common faults inherent in all chainsaws, and individual faults, which may vary depending on the type of pump and worm gear installed on a particular model. Let’s start troubleshooting in order.

It is forbidden to operate a chain saw if the chain is not lubricated. This is detrimental to the bar, drive sprocket and chain, and can result in serious repair costs.

Signs of malfunction of the lubrication system, checking its functionality

  • Chainsaw chain is dry and has a pale, shiny appearance.
  • The chain stretches relatively quickly.
  • The tire is very hot and may even partially melt the paint.
  • Oil from the tank hardly ever goes away.
  • Cutting performance on a sharp chain has dropped

All these signs indicate that the lubrication process is not working properly. To check the oil flow in the lubrication system, remove the side bar and start the chainsaw. Then you need to increase the speed a little watching the end of the oil line. If oil is coming in, most likely not enough for proper lubrication and you need to clean or replace the filter and, if possible, adjust the supply. If it is not coming, the problem is more serious and requires further diagnostics.

There is a way to check oil flow without removing the tire. To do this, point the end of the bar toward, for example, a freshly cut billet on the cutting side and increase the RPM as much as possible, while trying to keep the end of the bar no more than 10 cm away from the billet. If oil spots start to appear on its surface, it means that oil is being pumped.

Troubleshooting

After it has been determined that the oil does not flow, further diagnosis is possible only if you completely remove the oil system. Of course, in some situations changing the filter helps, but this is very rare.

Access to the oil pump on some models is only possible after a complete disassembly, so if you don’t know how to repair power tools, it’s better to leave the repair job to professionals.

The most common faults

  • Oil hose breakage. It can sometimes be detected by visual inspection. The problem can be solved by replacing the defective part.
  • The absence of threads on the shaft of the oil pump, its replacement will help.

Individual faults in the STIHL MS 180 lubrication system

Since the STIHL MS 180 is one of the most common chain saw models, I want to detail on one inherent only in her fault and describe how to fix it without replacing parts.

On the STIHL MS 180 chain saw it is fairly common to find an oil pipe leaking where the oil pipe from the tank is attached to the chain saw. You can tell when there is unusual lubricant leakage on the underside of the tool.

To fix the problem remove the chain saw handle, take the hose out of the seat, clean and degrease. After sealing the pipe put sealant on the seating and install it in the chain saw.

Read more on troubleshooting and how to fully diagnose the STIHL chain saw lubrication system in this video, which shows how to disassemble and repair the lubrication system, step by step.

STIHL MS 180 chain saw repair. No oil supply.

The main reasons why the STIHL STIHL 180 does not flow oil.

Your chain saw’s fuel system: 1. fuel filter, 4. fuel filter.5. carburetor, 3. manual priming pump.

If the carburetor is properly adjusted, it will use only as much fuel as is necessary. Otherwise it will end very quickly.

Slow reduction of fuel in its operating time

The chainsaw is a normal process. If it is absent, the chain is lubricated incorrectly, so the work with a chainsaw will fit. It is necessary not only to be able to fix problems, but also to detect them without the help of others.

Manually change the fuel supply is an option. Correctness of work of a lubricating complex of accounting programs is defined by a method of the tire. If there is oil splashing, it means that our customer is doing the job right.

Troubleshooting chain service problems

During the chainsaw operation it is necessary to watch the chain regularly for lubrication. Because this part works in the most demanding conditions. The chain is subjected to constant overheating, dust and abrasive particles are clogged. This has a negative impact on its service life. Lubrication is the answer

Oil is pumped to the chain from the oil reservoir, so the chain can be operated without any problems.

The chain is not lubricated and there is a high risk of overheating. When there is no oil supply, the chain gets stretched. This leaves the possibility of the chain jamming or popping and can result in severe injury.

Channels through which the fuel supply, be clogged with small particles, because it is purposeful to clean them from time to time. It is important to keep an eye on the oil level in the reservoir. Debris in the channel is a frequent cause of chain brake failure. This can have a negative effect on your work.

Keeping the channels clean and taking care of your chainsaw will keep it running for a long time.

Here are two more pictures (since the video did not show it very well).

The red arrow on this picture shows the shoulder.

The second photo shows the correct position of the oil pump (bottom view of the chainsaw). The red arrow points to the groove (channel) in the pump housing; the blue arrow shows where the channel is located. BACK (toward the back handle of the chainsaw).
