Husqvarna saw does not spray oil on chain
Fixing oil leak on Chinese chain saw (Fotoretto)
In some cases, chainsaw owners have to solve more complicated problems to fully restore the functionality of their cutting tool.
Chainsaw does not deliver full power
In addition to the problem described above with a lack of gasoline or air in the cylinder, a clogged muffler can be the cause of poor power output.
Leaking carburetor and clogged injector
Over time the screws that secure the carburetor cap can become loose or the gaskets can fail. A clogged filter or its unskilled replacement can lead to clogged injectors. All this also impairs chainsaw performance and reduces service life.
The chainsaw does not keep idle speed
It is not uncommon for a chainsaw to refuse to idle smoothly after long periods of transportation and constant use. This problem can usually be fixed by adjusting the carburetor.
You can learn how to debug your carburetor properly in this
If the carburetor is tuned like clockwork, it should be checked:
- The fuel system. Start with the fuel pump.
- Muffler. There is a high probability that because of the large amount of accumulated soot the engine cannot function normally.
Chainsaw loses power under load
If in the process of operation the power of the saw has disappeared somewhere, then you should look for the problem in the following places:
In 9 years of trouble free operation, I have changed the starter and clutch spring once. The machine is quite decent in its capabilities. Among the disadvantages are the high cost of brand name oils. My chain saw uses chain oil twice as fast as my gasoline. As far as I know, this phenomenon is typical for many budget cars. Test placement of a new oil pump did not work. Found a suitable equivalent, TAD-17 transmission, situation stabilized. Among other disadvantages are absence of toothed stop for securely fixing the saw when cutting round timber, lack of visual control of fuel and chain oil level, not very convenient scheme of chain tightening.

I like the saw, it’s lightweight, easy to work with, powerful enough and easy to maintain. I have been using it for almost 7 years, each season I have about 50-60 cubic meters of firewood. The tire is long enough to cut down old trees. For sawing oak I bought an expensive carbide chain, and now I have a big problem with sharpening. The engine is sensitive to the quality of fuel, sudden changes in air temperature. In some cases, it is necessary to compensate by additional adjustment of the carburetor. At one time I bought the tool for only 8000. Now I wish I’d bought two at once. The service said that the production of cheap chainsaws moved to China. If so, you can expect that the reloading will inevitably affect the quality of the range produced. Dimon
One of the principal chainsaw systems, the work without which is impossible, is the chain saw‘s forced lubrication system. Everyone knows that the chain rubs against the guide bar when the saw is in operation, which causes heat and early wear of the guide bar. To mitigate friction, the chain mechanism needs to be lubricated routinely.
To supply oil for chainsaw chain lubrication, in the tool is used a special pump, which doses, based on the number of revolutions of the motor, delivers lubricant to the bar of the saw.
The oil for chainsaw chain lubrication is used in the system, having high adhesive characteristics, it is necessary for the even distribution of oil around the bar and its retention even at high chain rotation speed. Let’s have a closer look at the oil supply system implemented in modern chainsaws.
Depending on the brand of chain saw, the details of lubrication complex accounting programs of course differ little structurally, alas their total number and connection scheme remains constant.
The main components of an accounting (soft) lubricant part are:
The main component of the accounting programs complex. the pump. Its operating principle is as follows. When the speed of the engine increases, the pinion on the main shaft through the worm gearing drives the pump shaft. The rotation of the shaft usually puts some pressure in the oil gallery, forcing the oil to flow through the oil pipe toward the guide bar.
To reduce the likelihood of various oil leaks while the saw is in operation, periodic maintenance should be performed. During this process, all hoses and gaskets must be checked for leaks. If they are detected, it is necessary to pull the coupling elements together.
The quality of the oil in the pump must be checked. The oil must be of good quality and used strictly in accordance with the characteristics indicated in the product data sheet. In this case you should never use used oil, because it has a non-uniform structure. It’s also absolutely necessary to periodically bleed the oil pump. This prevents debris from coking in the working channels.
Poor lubricant quality will impair the performance of the tool and shorten the service life of the tool.
In addition, if the chain is not well lubricated, it can break down and is expensive to replace.
After you have finished your sawing work, it is absolutely necessary to clean the saw from sawdust. If you do not use the chain saw for a long time, it should be tilted in an upright position. This will allow the oil fluid to flow evenly through all the channels of the tool. This even distribution of the lubricant avoids vacuum plugs that can cause the oil pump to malfunction.
When a chainsaw chain moves in the guide bar groove, a great deal of heat is generated as a result of friction. If your chainsaw is not getting oil to the chain, you need to stop work and take all measures to fix the faulty lubrication system. The combination of heavy loads and overheating leads to its accelerated wear and early failure.
- All chainsaws and their electric counterparts, without exception, are equipped with the same operating systems that lubricate the bar, saw chain and its drive components.
- This unit is equipped as standard with a reservoir from which the chain oil is pumped to a fixed or adjustable pump inlet.
- The dosed amount of operating fluid then enters the bar groove, where the saw chain shanks distribute it evenly over the whole bar and the drive sprocket rim working surface.
Bus bars from 400 mm in length are fitted with a sprocket wheel. Periodical lubrication of the bearing is carried out individually after 6-8 hours of operation.
Design of the lubrication system
Depending on the brand of chainsaw, parts of the lubrication system may vary slightly structurally, but their total number and connection scheme remains the same.
The main components of the lubrication system, are:
The oil tank is normally located in the engine crankcase.
The main brands of motor oils for chain saws
STIHL and Husqvarna are the leading manufacturers of quality chainsaw and brushcutter lubricants. Their range includes both regular mineral greases for two-stroke engines and synthetic oils for heavy duty. Let us have a closer look at our product range.
STIHL HP mineral lubricant was specially developed by STIHL engineers for use in their tools. That’s why owners of STIHL chain saws and brushcutters are advised to use this type of oil.
Red in color, shelf life in a closed container for up to four years. Packaged in several types of packaging, so you can choose the most convenient packaging. Not so long ago there appeared a convenient container of 20 grams, which are diluted by one liter of gasoline. For those who seldom use a chainsaw it is the right choice. Can be diluted and used immediately.
STIHL HP meets the high European standards.
Another STIHL oil. Has a synthetic base, which improves combustion, cleanliness and engine protection.
Manufacturer’s recommendation for hard, continuous use. Ideal for low temperatures. HP Ultra is environmentally friendly, t. к. Oil spilt on the ground, degrades 80% in just 21 days.
Available in two types of containers, 100 ml and 1 liter bottles. The proportion of ready-to-use fuel mixture is 1:50, which means that a 100 millimeter bottle is enough to make 5 liters of mixture. Green color. Shelf life 4 years.
It is worth noting that STIHL oils, before going on sale pass through the company’s laboratory, where they are tested for compliance with all requirements.
When developing oils, much attention is paid to fuel burnability, starting characteristics when cold starting, biodegradability, viscosity changes at different temperatures (information from the official company website)
Husqvarna HP 2-stroke
Husqvarna HP oil, like its STIHL analogue, is also specially formulated for 2-stroke engines.
According to the manufacturer, this type of oil has additives that compensate for the poor quality of fuel, which is important in our country. The declared octane rating of gasoline at gas stations, rarely corresponds to the real one.
Husqvarna HP is a semi-synthetic oil with a green color. Packaged in 1 liter or 10 liter containers. Proportion of the mixture is 1: 50, i.e. е. 20 grams per liter. in the period of the cutting-in period or when working in cold weather it is possible to increase the oil ratio to 1:40, which gives the engine more protection and extends its service life.
Today, on the market there is a wide variety of lubricants for two-stroke engines from different manufacturers. For this reason, to answer the question, what is the best oil for a chainsaw, it is quite difficult. Our opinion, you should trust the reliable companies, which are STIHL, Husqvarna, Oregon, Champion. It is their oils which will maximally protect the engine of your tool and prolong its life span.
Unscrupulous manufacturers often disguise their products under well known brands (Husqvarna, STIHL, etc) and also try to sell them as real raw materials. д.). Such oils are of low quality and can damage the engine. In order not to be deceived, you need to buy lubricants from official representatives who have the necessary certificates for the products. How to distinguish the fake from the original you can learn from
The basics of chainsaw maintenance. Do it Right!. The naked truth!
The purpose of this post is to give practical advice to everyone who owns chain saws. We are going to talk about the chainsaw. Preparing the saw unit for work, simple rules that will help save on unnecessary costs. Also, this post will be helpful to those who have no experience with chain saws at all. A saw unit is a chain, bar and drive sprocket.
You have purchased a new chain. Take your time when you put it on the bar. soak the chain in oil for 12 hours to impregnate all the connecting pieces of the chain. The question may arise as to why? Often chains come from the manufacturer already greased, is that not enough?? This is only sufficient for shipping and storage. For a complete job. no! The soaking of the chain should take at least 12 hours. Only after this procedure is it safe to put the chain on the bar. The tensioning of the chain is important. There are a few requirements:
The chain must fit snugly on the bar. There must be no slack at the bottom.
The chain should move by hand on the bar.
Another point that users do not usually observe, but that is often described in the instruction manuals for the saws. In order to tension the chain, it is necessary to lift the bar by its “nose”, tension the chain and fix the bar.
Running in of the chain
Start the saw, give it a medium rpm and let it idle for 2 minutes (this is done so that the sprocket and the chain could be lubricated and warmed up). Stop engine after 2 minutes, check chain tension. If necessary, retighten it if it is loose.
Never tension the chain when the chain is hot, but allow it to cool before tensioning. Otherwise, the chain will inevitably be stretched and will last a fraction of its original life.
Remember! The chain should be cool when tightened! When a heated chain is stretched, it is inevitable that it will be pulled out.
Lubrication of the chain saw
Many people think that any oil will do for the chain and bar lubrication. like car oil or something else.
Using automobile oil as an example. Automotive motor oil is very fluid and if the top is lubricated, the bottom of the headset and the working part will overheat, subjecting it to wear and tear. Use a special lubricant for chainsaws. adhesive oil. The adhesive oil has a certain viscosity and is especially designed by the producers for certain tasks. The oil does not drip off. it sticks to the chain. As a rule saw producers supply oils to their products, which ensure optimal performance of the saw system. I recommend to use only special oils. Don’t be thrifty. remember “A miser pays twice”!”
In the first 30 minutes of use keep an eye on the chain tension. If it slackens, stop the process. We wait for the chain to cool down, then retighten it and go back to work.
Chain sharpness is important. Remember the main thing. a sharp chain on its own “climbs” into the wood!
A dull chain puts unnecessary strain on the chain as well as on the saw unit as a whole. If you put extra effort in your work productivity automatically decreases and the load on your saw unit increases.
The saw is only intended for cutting wood!
One tank of mix in a chainsaw equals one work cycle.
There are two kinds of sprockets. one with a removable ring and one with a fixed ring.
Has a direct effect on the performance of the machines!
Sprocket must be replaced if wear depth is 0.5-0.6 mm.
Do not let the sprocket wear out too much! This will not lead to anything good.
What will happen to your saw unit if the sprocket is excessively worn??
The chain pitch will not match, the chain will automatically stretch. If the sprocket is extremely worn after pulling the chain, it may break. The speed is extremely high and you risk losing a new chain.
Busbar or saw headset
The guide bar needs to be cleaned! Sawdust and oil build up in the bar groove. On the guide bar the lubrication hole needs to be cleaned! Lubrication hole is blocked. no lubrication! All this leads to overheating and wear of the saw unit.
To check whether or not there is enough lubrication, you need to do the following. Approach to the light surface, drive the saw, give full rotation, bring the “nose” of the guide bar to the same surface 2-3 cm on the surface should leave an oily trace that will say. enough lubrication.
Burrs may appear on the bar due to natural wear.
It is necessary to deburr the guide bar with a file, if you don’t do this the guide bar will wear out more intensively.
For even wear of the tire rails it is necessary to flip them over! First day you work on one side, second day on the other.
No need to go too fast and too slow, it might scorch the drive sprocket and the clutch itself.
It is necessary to cut at high and stable rotation speed!
The chain should be soaked before work.
Watch out for worn drive sprocket or replacement sprocket and change it on time!
One more thing.
Do not forget to perform the following operations!
External saw cleaning. Always keep the tool clean!
Clean air filter. The key to engine health!
The chain is sharpened. If the chain is always sharp!50% of sawing problems!

How to dilute gasoline for your Husqvarna chainsaw
For productive work and long service life at high power the proportion of oil and gasoline in a chainsaw should be measured with a measuring cup in relation to the ingredients of the fuel mixture. When making even a small amount, a small inaccuracy affects the quality of the fuel.
For dilution use quality gasoline with a minimum octane number. RON 90. If the parameter is less than recommended, the engine starts to knock, which leads to its overheating and increased load on the bearings. Always work at high engine speeds and choose gasoline with a higher ratio.
It is recommended to use 2-stroke oil.
To properly dilute gasoline for a chainsaw, use the following mixing scheme:
- for motors with a cylinder displacement up to 80 cm³. 1:50 (2%), t.е. 5 liters of gasoline equals 0.10 liters of oil;
- for engines with a displacement greater than 80 cm³. 1:33 (3%), t.е. 5 l of gasoline. 0,15 l of oil.
