The Partner 350 chainsaw is a “relative” of the famous Husqvarna brand, since Partner is a subsidiary of Husqvarna. Lightweight and convenient, reliable and simple, Partner 350 is widely used in country houses and private households. Trimming branches, branches, and felling trees is not a complete list of jobs that can be done easily and effortlessly with a saw. A brief overview will help you get to know this in more detail.
Appearance of the Partner 350 chainsaw
Specifications
According to its data, Partner 350 belongs to the household (amateur) type and fully satisfies the needs of any consumer. To get a general overview of the chainsaw, just look at its main characteristics.
Characteristics of Partner 350
For those familiar with chainsaws, one glance is enough to determine the character of the 350 Partner. A fairly powerful engine and a decent length of tires mean that this will be an indispensable assistant on the farm, but it’s hardly suitable for professional felling.
Determine the length of the chain.
The chain length depends on your tire. Since tires come in different lengths - 35 cm, 40 cm, 45 cm, then the length of the chain will be different.
The length of a chain is measured by the number of links. We count the links. You can do it one link at a time. You can fold the chain in half and count it in pairs. And we get the second value.
For example, the chain in the photo consists of 50 links. (handle points to one link)
And now we know two indicators of our chain:
- step 38
- 50 links (chain length)
By the way, if we multiply these two indicators and divide by 2.54 (this is an inch), we get the length of the tire in centimeters.
(1.8 cm * 50) / 2.54 = 35 cm.
Device
The general arrangement is made in a traditional style. It is distinguished by its simplicity, which means high reliability of the unit.
Partner 350 chainsaw device
The diagram of the general structure of the Partner 350 chainsaw clearly confirms this.
Starting the engine is simple and reliable. This was made possible thanks to the presence of electronic ignition. The primer (fuel booster pump) plays a major role during startup.
The air filter is equipped with a double air purification system. As a result of equipping the starter drum with an impeller, large debris particles do not reach the filter at all. Thanks to this, its service life increases, and the degree of air purification increases. In general, this has a beneficial effect on engine performance.
Safe handling of a running saw is achieved by the presence of a chain brake operating in two modes - manual and automatic.
The oil pump only turns on while sawing. This means that the chain lubrication system operates automatically. It must be borne in mind that different types of oils are used to lubricate the chain and prepare the working mixture. Video will help you find out what oil is used for the Partner 350 chainsaw
Saw chains. The Partner 350 saw is equipped with an Oregon 91P052E 3/8″ 1.3 mm 52-link chain. Replacement with analogues is acceptable: Stihl 39970000052с and others. For example, Husqvarna 5776151-22. Pay attention to the fact that with a chain pitch of 3/8″ and a groove width of 1.3 mm, the number of links does not exceed 52. Less (46 – 50) is possible, more is not advisable.
The anti-vibration system on the Partner 350 works a little harshly. Considering that this saw is not intended for professional use, the system as a whole can be considered satisfactory. By the way, significant improvements have been made in this regard on subsequent models.
Recommended components, parts, mechanisms and fuels and lubricants cannot be replaced with analogues.
Saw bars Partner
Partner chainsaws, for example the 350 or 360 series, are very common in Russia and neighboring countries. The bars and chains for these chainsaws are consumables that wear out quickly and therefore require replacement. However, in addition to “Partners”, there are a large number of other manufacturers and models of saws on the market with corresponding tires for them, and it is not always reasonable to buy exactly those consumables that are intended directly for Partners. Standardization and unification of sizes and components leads to the fact that you can choose a tire according to two criteria:
- The most affordable to purchase (despite the price, alternative tires may be the only available option, so there is no need to waste time looking for something original);
- The most affordable.
Generally, ]Oregon[/anchor] consumables are recommended for partner. On the company's official website you can select parts by parameters. In this case, as a rule, the determining value is the choice of tire length - 12 or 14 inches. Also important from an operational point of view is the choice of profile of both the bar and the chain - Low profile or similar or Extra Guard or similar.
The difference between them is the overall size of the bar and chain, in which Low profile is better suited for work related to precision cutting, but has less stability compared to Extra Guard.
For many owners of Partner saws, the question often arises - how to use chains and tires from Stihl? Even though the sizes are the same, the lengths of the Partner and Stihl chains may be different. So, for the Partner 350S saw with a 40 cm long bar, a 1.3 mm groove and a 3/8 inch chain pitch, the number of links in the chain is 56 pieces. At the same time, Shtilev chains are shorter.
Announcement:
The solution to this problem is the following procedure - to use Shtil chains in Partners, you need to buy a short tire 30 centimeters long (12 inches). Oregon tire part numbers for this option are 120SXEA041 and 120SDEA041. Moreover, if you still want to use 14-inch tires (with catalog numbers 140SXEA041 or 140SDEA041), then such chains will not work - you will have to look for options with 52 links.
Despite the fact that, according to many users of Partner chainsaws, their chains and bars (those produced by Oregon) are less reliable than those produced by Husqvarna, there is no point in believing these rumors. It is a fact that Oregon, which has its own production facilities, transfers part of its chains to Husqvarna, which then sells them under its own brand.
Some owners of Partner chainsaws, particularly the 352 model, are stumped when trying to change a chain with a 0.375″ pitch. Moreover, in fact, a complete analogue of this step is ordinary 3/8-inch chains, in this case 3/8 by 1.3 millimeters for 56 links. These can be not only Oregon products, but also any other manufacturer with similar parameters.
The price of tires for partners does not differ from the cost of products for other saws. So for a high-quality branded Oregon you need to pay more than 2 thousand rubles; tires costing about 1 thousand are quite suitable. As with many other products, tires that are too cheap, even if all the parameters are met, are in fact too expensive to operate, since they do not last too long.
At the end of the article, advice on how to increase the sawing speed of a Partner, in case someone doesn’t know: choose a shorter tire. The saw will be much lighter, the speeds will be higher, the chain will be lubricated better, but the load on each tooth will, of course, increase. However, if you do not need to cut thick trees, short bars and chains are the best option.

Preparing the saw for use
Before starting work, you need to configure the Partner 350 chainsaw. A properly prepared saw with a well-run-in engine does not cause any complaints from users. Setting up the unit is simple. Before starting the engine, check:
- tire mount;
- chain tension;
- ease of chain rotation;
- brake operation;
- refueling with fuel and oil.
After this, the engine starts. After warming it up, you can start working.
Pros and cons of the Partner 350 chainsaw
Like any mechanism, a chainsaw has its pros and cons. The main positives will be the following:
- The product is a product of a well-known manufacturer. This speaks volumes about the quality of the saw and the developed service network.
- The engine is equipped with a primer, which makes it easier to start, especially in the cold season.
- The piston and cylinder of the engine are additionally treated with chromium, which improves their performance and helps extend the service life in general.
- The light weight of the 350 Partner and the relatively short bar make it much easier to control the saw.
Of course, there are shortcomings, but against the general background they look insignificant. Somewhat difficult access to the air filter and the lack of visual monitoring of the lubrication level do not improve the weather. Those who have installed an extended tire note low engine power. It `s naturally. That's how it should be. A triple violation - an unauthorized change in design parameters by the manufacturer, additional load on the engine and a direct violation of the operating instructions will certainly not improve the operation of the unit.
Basic malfunctions and their elimination
The main malfunctions that you can fix yourself and how to eliminate them are described in detail in the “Operating Instructions”.
Engine won't start
In this case, it is necessary to check the gap between the spark plug electrodes. It should be 0.5 mm. At the same time, the electrodes need to be cleaned of carbon deposits. In most cases, this is enough to get the engine running again. Starting is also affected by contamination of the carburetor, fuel and air filters. After washing them, the engine, as a rule, stops being capricious. On the pages of the site and the Internet there are many photos and videos on restoring engine performance.
The engine does not develop power (stalls under load)
To the previously listed reasons, one more is added - the carburetor needs to be adjusted or the muffler needs to be cleaned. Adjustment is carried out using adjusting screws. Detailed information on this issue can be found on the website. The video shows the process of detecting and repairing a chainsaw failure.
Broken starter cord
Partner 350 is found quite often on chainsaws, and on all chainsaws, so Partner 350 is no exception. This problem is not difficult to fix yourself. After watching the video, it becomes clear how to replace a broken starter cord.
Open circuit
Mainly due to its overheating during operation. The cause of overheating is a lack of lubricant supply or oil channels clogged with dirt. First of all, all oil channels are cleaned, the inside of the chainsaw in the area of the drive sprocket and the tire groove is cleared of debris (sawdust). Only after this can a new chain be installed. If a problem is detected in the operation of the oil pump, the saw must be repaired in a specialized workshop.
What kind of chain is on Partner 350
Professionals know very well that it is not the strength of a chainsaw that makes it a good tool, but how well it is used. With proper care, any chainsaw can last a long time, demonstrating excellent performance. If it's the other way around. Improper handling and safe operation of the tool will shorten the life of the tool and lead to premature failure.
One of the most important aspects of proper maintenance is chainsaw chain maintenance. You should know how to tension a chain on a chainsaw, how to sharpen it and lubricate it. It is still very important to have a good understanding of its characteristics. This knowledge can be very useful if you need to select a new chain.
Circuit Function and Correct Voltage
The correct position and tension of the chainsaw chain is very important not only for its proper operation, but also for the safety of those who work with it, as well as those around them. If the chain is not tensioned correctly, it can accidentally fly up during operation, which can cause damage not only to the chain itself, but to the entire chainsaw. However, this is also undesirable when the chain is too tight. This can also have negative consequences in the form of increased load on the engine, which in the future will lead to its early failure and reduce the overall life of the chainsaw. The chain has one very important property: it blocks the tire, which prevents its arbitrary movement. Therefore, special attention should be paid to caring for the chain.
Choose the right chain
Chain damage is common, so before you ask yourself how to properly tension a chain on a chainsaw, you need to know which chain is suitable for your particular model of chainsaw. The main selection criterion is its pitch. The pitch is called the distance between the teeth. The distance is chosen between the nearest teeth and is measured in inches. The most common are 0.325, 0.375 and 0.404 inches. Refer to the owner's manual for your specific chainsaw model for the steps, and this will primarily depend on the purpose of the tool.
Each saw has its own pitch, with the exception of universal professional tools. The pitch of the circuit also depends on the engine power. The more powerful the chainsaw, the greater its pitch and the more difficult it is to keep it in operation. For example, the Patriot compact low-power chainsaw has a pitch of 0.325. However, there are also more powerful models. One of them is the German STHIL with a pitch of 0.404. Which, as we see, is larger than the Patriot chainsaw,
Step is one of the most important characteristics of circuit parameters. This means that you should not choose a high pitch chain for low power chainsaws. This may not only not match, but also disable the tool.
The Importance of Proper Circuit Setup
Normal operation of a chainsaw causes vibrations that can significantly reduce the tension on the chain by the blades or nuts used to secure it. With intensive use, the chain becomes tense and does not fit well on the teeth of the chainsaw, which can create unsafe conditions for the operator. Proper operation of the tool includes checking all nuts and bolts before and during use for safety. If the chain nuts are too loose on the saw teeth, then you will most likely need to tighten the chain properly and then tighten the blade itself.
Always be aware of your safety and wear protective gloves and safety glasses before starting work. The chainsaw should be placed on a flat surface such as a workbench or table. If previously used, the engine must be completely cool. Next, to prevent the saw from starting accidentally, disconnect the wire from the spark plug connector. Now you can start setting up the circuit.

How to tension a chain on a chainsaw yourself
It's not difficult, the main thing is to remember your own safety. So, how to put a chain on a chainsaw? Stand in front of the chainsaw, facing you with the blade facing you. Grip the tip of the saw with one hand and lift slightly. Insert the flat head screwdriver firmly into the adjustment screw to the right of the blade as you face the saw blade. Turn the screw clockwise to increase chain tension, or counterclockwise to decrease it. Grab the chain with one hand and pull the blade. The tension is correct when it is slightly loose, if it pulls in the direction of the blade and at the same time sticks firmly to it.
If this is the case, further adjustments to the chain on your chainsaw may not be necessary. If not, you need to configure. Loosen or tighten the adjustment screw to obtain the correct shape. Hold the tip of the chainsaw with one hand. Tighten both left blade mounting nuts using a saw repair kit or an adjustable wrench. Place the spark plug wire in place and press firmly.
Tools you need
When buying a chainsaw, it is often equipped with tools for its maintenance. The chain must be adjusted. It looks something like this: There is a flat head screwdriver on one end and a flat head screwdriver on the other. another. wrench fits nuts To understand how to tighten the chain on a chainsaw, refer to the owner's manual for that model of saw.
Security measures
When using a chainsaw, you should wear personal protective equipment, including eye and hearing protection, leather gloves and a hard hat.
For safety reasons, when operating a chainsaw, it is recommended that another person be nearby to help.
Chain sharpening
Everyone knows that from time to time it is necessary to sharpen the chain on a chainsaw. However, not everyone knows how to do it correctly. A sure sign that a saw needs sharpening is the shape of the sawdust. If they look like fine dust, the chainsaw blades are dull and need sharpening. If the chain is severely worn and can no longer be sharpened, it must be replaced with a new one.
Chain sharpening methods
There are many ways to do this. Here are some of the most common examples:
- Sharpening with a file. Its convenience lies in its simplicity, as there is no need to use complex equipment and machines. In addition, this sharpening can be done directly on the job site, which saves a lot of time.
- Sharpening on a machine. It is most often used in equipped service centers or workshops, but it also occurs in personal households.
- Sharpening with a grinding machine. One of the most difficult ways to aggravate this is because it requires special skills. Therefore this method is not widely used.
How to shorten a chainsaw chain yourself
Chains must always be in good technical condition. All defects and malfunctions must be given due attention. You must follow the general safety rules and recommendations in the operating instructions. This is the only way to avoid injuries and other undesirable consequences when using a chainsaw and extend its service life.
Sometimes, due to wear, deformation or other reasons, it is necessary to replace or shorten the chain. It should be noted that a sagging chain does not mean it needs to be replaced. It needs to be changed if it is not fully customizable.
Sometimes the chain can sag with heavy use. This is due to severe overheating of the metal, its expansion and, consequently, its elongation. A way out of this situation may be to periodically stop, allowing the circuit to cool down. However, this is not always possible. Another situation may arise when, for example, you need to install a chain that is somewhat long.
Voltage regulation
The chain tension must be adjusted using the chainsaw bolt, which is located where the gear stops are located.
It is important to understand how to tension a chain on a chainsaw. Do not pull it all the way as it may soon stretch out again. The chain should have a small margin and sag slightly. It's not difficult to check this manually. It should be a millimeter away from the tire.
It's best when the chain is long enough that you can remove a few links. In this case, we can use the original chainsaw chain links. You can block them with a metal hacksaw, but it will be much easier to do it with a sander. To do this, unscrew the link, polish it, then cut off the excess part. Then we pull the rivets out of the unnecessary links, remove them and connect the chain ourselves. For this purpose, you can use special rivets, but if not, then you can use ordinary steel wire. Place the chain on a solid base and start riveting on both sides.
