One of the most popular household chainsaws in Russia is the 350th saw model from Partner. This can be explained by a number of advantages of this model.
The most important qualities of such saws, which characterize them on the positive side:
- compactness and light weight with sufficient power;
- relatively affordable price;
- durability;
- excellent repair base.
Chainsaws Partner - features
Many sources claim that it was this Swedish company that produced the first mass-produced household chainsaws in Europe. And this happened in 1949.
We generally believe that these are good Chinese saws, and this is partly true - most of the Partner chainsaws sold on our market are assembled in China, as is honestly written on their nameplates. But besides China, saws of this brand are also produced in America, Italy, Norway and England, and they can also be purchased in Russia.
For more than 10 years, this brand has belonged to the Husqvarna concern, one of the leading manufacturers in this segment, which affects not only the design features of the saw, but also the widest network of service centers capable of quickly and efficiently servicing it.
Few people know, but for the first time the chain brake of chainsaws and the heated handle system were used on Partner chainsaws, so they should not be underestimated.
There are about 30 modifications of chainsaws of this brand. From the lowest-power saw Partner 340S produced today, with 1.44 kW of power at 13,500 rpm, to the most powerful Partner 842, with its 1.6 kW at 12 thousand rpm.
But, perhaps, the 350th model remains the most purchased in Russia.
Breather clogged
The breather of the presented model becomes clogged when low-quality fuel is used. In such a situation, repairing the Partner 350 piston chainsaw should begin with inspecting the carburetor. In order to see it, you will have to remove the top cover of the device. Next, the ignition module is twisted
After this, it is important to immediately disconnect the crank. In this case, you will have to use the keys
The next step is to disconnect the drum.
Immediately behind it is the carburetor. There is no need to remove it for inspection. First of all, the throttle is checked. In some cases, this may be the problem. If the throttle is fine, you need to look at the tire. When it is damaged, its sides are slightly knocked down. Cracks may also be observed in the central part of the tire. If the part is deformed, it will have to be replaced. It is better to purchase spare parts for the Partner 350 chainsaw in specialized workshops. It is quite difficult to install a tire on a carburetor yourself. In such a situation, it is more advisable to contact a specialist.
Review of saw Partner 350
This is what we will look at in more detail.
Specifications:
- power 1.52 kW;
- working volume 36 cm3;
- idle speed 3000 rpm;
- maximum recommended rotation speed 13,000 rpm;
- saw bar length 40 cm;
- chain pitch 3/8".
It is possible to use saw bars 45 cm long, but for this length the saw is still rather weak.
The saw is equipped with a hand chain brake, an easy start system, a primer for pumping fuel, a carburetor air damper regulator, has chrome-plated cylinder walls and a cyclotron air preparation system. It is assembled quite well and, inferior in class to its more famous classmates from Husqvarna and Shtil, surpasses in its consumer characteristics almost all other chainsaws in the household segment.
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.
Chainsaw Partner 350: faults and their elimination
One of the main features of this saw, its users note durability of operation with a minimum number of failures. And yet they happen. To determine why the saw stopped working, you need to perform basic diagnostics.
If the saw does not start, then:
- there is no spark on the spark plug;
- fuel is not supplied;
- no air coming in.
First you should check for the presence of a spark: by unscrewing the spark plug, connecting it to the high-voltage wire and placing it on the cylinder, pull the starter. If there is a spark, then clean and adjust the gap on the spark plug (0.5 - 0.65 mm). If it is not there, then you need to change: either the flywheel or the coil (magneto). In addition, the spark plug itself may fail or the high-voltage wire may break.
The next step is to check the fuel supply. To do this, you need to disconnect the supply hose from the carburetor and check its presence. Absence may indicate that the fuel filter or delivery system is clogged. The carburetor itself may also become clogged.
If you do not have experience in repairing and cleaning it, entrust this work to specialists.
If the air supply deteriorates, the saw should start, but it will not work well. Remove and wash the air filter. Put it back in place only after it has completely dried.
If the saw starts well, idles and stalls when gas is supplied , the muffler is most likely clogged. Remove, disassemble, wash, put back and continue working.
You can also easily change the saw bar and chain, carburetor, starter, oil pump, ignition and clutch with your own hands.
Here is a video of a complete disassembly of this saw:
And you will be able to replace a broken starter cable after watching this video:
We recommend entrusting more complex chainsaw repairs related to replacing the cylinder-piston group or crankshaft to specialists, although if you are familiar with two-stroke engines, then this work will not be difficult for you, and spare parts for Partner chainsaws are not in short supply in Russia.

We advise you to regularly monitor the serviceability of the safety group: brake and chain catcher. Remember that the saw should be thoroughly cleaned of small chips. It can not only clog technological holes in the oil pump and other places, but also interfere with the operation of the brake.
Operating Instructions for Partner 350
In this manual you will find not only a detailed description of the saw, but also basic techniques for working with the tool. We would like to draw your attention to the fact that this chainsaw can run on AI95 or AI92 gasoline with the addition of oil for two-stroke engines in a ratio of 1:50.
The lineup
In their price range, Partner branded chainsaws are in high consumer demand. The presented review shows the characteristics of models with high ratings.
Partner P340S
The model, priced from 6,000 rubles, is focused on performing the following work:
- for the preparation of firewood for a stove or fireplace;
- maintenance of garden and forest park areas;
- crowning woody plant decorations.

Partner P842
The household version of a powerful and durable home saw is equipped with a strong drive, traditional for the Partner 2.1 chainsaw model range. The cylinders of the power units of this series received decompression valves and wear-resistant chrome plating. In terms of durability, the drive sprocket of the saw set has been improved.
The design is complemented by an EcoBoost exhaust gas purification system and a reinforced drive for the standard oil pump. The operational advantages of double air purification and the efficiency of the proprietary innovative vibration damper are also involved.
Adjusting the carburetor of the Partner 350 chainsaw
This is the most frequently performed procedure when servicing a chainsaw, performed by the owner himself, so it is worth learning. It is similar to adjusting the carburetors of most chainsaws and is described in sufficient detail in the proposed video:
It is important to complete it by adjusting the idle speed screw, which ensures that the chain remains stationary when operating in this mode. If the chain does not stop at the lowest stable speed, this indicates that the clutch needs repair and the saw is unsafe to use.
How to start a chainsaw
The effectiveness of any tool directly depends on compliance with the rules of its use. First of all, this concerns the launch. This should be done in the following sequence:
- Apply the chain brake by pressing it forward.
- Remove the protective cover from the tire, if equipped.
- Turn on the decompression valve, which will make the starting process easier.
- Press the fuel choke. This is necessary to reduce the number of swaps.
- Set the combination lever to the idle start mode all the way down, having previously locked the gas lever.
- Place the tool on a flat surface, grasp the chainsaw with both hands so that the cutting part is located at a distance from this surface. In this case, place your left hand on the handle, and your right hand near the starting cable. The tool needs to be secured with your foot, for which you can simply step on the back handle.
- Now the starting rope must first be pulled tight and then pulled several times. In this case, you need to move upward from the body.
- As a result of a short start, the engine will stall. Therefore, after this, the combination lever must be moved up one click, and then started again.
- If the engine is running, the throttle lever must be pressed and the combined engine must be switched to idle mode.
- Now the chain brake needs to be removed and you can start using the tool.
Despite the simplicity of the process, situations may arise when the chain saw still does not start. The reasons are not always related to tool failure. Perhaps not enough force was applied. If, after several attempts, the startup is unsuccessful, it is worth conducting a thorough inspection of the device.
Disadvantages of the saw
On the Russian market you can find low-quality fakes of the Partner 350 chainsaw, which is not only additional evidence of its popularity, but also harms the brand as a whole. And other models of this brand are popular with summer residents and farmers.
If you are ready to consider the Partner 350 as your home tool for sawing thin trees, trimming branches and other not very voluminous work, then you should also know the disadvantages, most often mentioned by their owners:
1. The vibration damping system is not of very high quality, as a result of which the hands get tired quite quickly. But, considering that this is a household tool that requires 15–20 minutes of rest every 20–25 minutes of work, you can put up with this drawback.
2. Oil leakage from the chain lubrication system, which, however, affects most chainsaws equipped with it, including the more famous relative of Partner chainsaws - Husqvarna. (link)
3. Lack of visual control of the oil level, which is not very convenient in operation, and operating the saw without lubrication will lead to rapid stretching, overheating and wear of the chain.
Of course, you can use this saw to cut down a tree up to 30 - 35 centimeters thick, but its main purpose is to work on the site. Therefore, in conclusion, we offer you the most objective video review of this model:

Drum repair
Breakage of the ram in the saw is accompanied by a loud sound when turned on. In this case, repairing the Partner 350 chainsaw with your own hands should begin first of all by inspecting the fuel system. The problem may be a broken carburetor. In some cases, the drum will fly out due to the crank coming out of the grooves. In order to inspect it, you need to open the protective cover. Next, the throttle is removed and the fuel system is checked.
All tubes must be connected. After this, you need to inspect the crank, which is located above the carburetor. If it has fallen off the grooves, you can straighten it yourself. However, if it is severely deformed, it will have to be replaced. The drum in this saw is located near the air damper. When it hits the coupling, its protective ring is damaged. If it is completely worn out, then the drum will have to be completely replaced. In this case, you need to know the product labeling. The installation of the drum is quite simple, and you can handle the installation yourself
In this case, it is only important not to damage the fuel system during repairs.
Fuel supply problem
A similar chainsaw malfunction can be determined by inspecting the spark plug. Fuel may not enter the cylinder for various reasons:
- The fuel filter installed in the tank is heavily clogged.
- The hole in the tank cap is clogged, preventing gasoline from flowing out.
- There is poor or no fuel flow from the carburetor.
If there is not the correct ratio between gasoline and air mixed in the carburetor or there is not enough fuel supplied, you should check whether the channels and the carburetor air filter are clogged. In addition, it may need to be adjusted.
Before cleaning, the filter is carefully removed and washed with detergent, after which it is left to dry. Then it is put in place.
The carburetor is usually adjusted using screws for maximum and minimum speed. When carrying out this procedure, you must strictly follow the instructions for repairing the chainsaw, otherwise you may damage the motor. Sometimes manufacturers leave only one adjustment screw to prevent inexperienced technicians from interfering with the operation of the carburetor.
If debugging does not fix anything, then it is worth cleaning the channels and filter mesh, and also checking the integrity of the membrane.
Do not forget that the carburetor is one of the complex mechanisms of a chainsaw, so you need to approach it responsibly when cleaning and disassembling it.
It consists of many small elements that can pop out unnoticed and be difficult to find. Often after disassembling this device, some users are unable to reassemble it.
What to do if the muffler is clogged
If the chainsaw engine functions normally at low speeds, but smokes and stalls at high speeds, then the reason is most likely in the muffler. Remove it first, but be sure to close the outlet. Then disassemble and clean from carbon deposits using a dry method or detergents, dry with a hairdryer, assemble and install.
Do not dry clean without special protective equipment, since carcinogens contained in carbon deposits are released in the form of dust. Inhaling it is very dangerous. When operating a chainsaw, it is necessary to monitor the quality of the fuel mixture.
Chain failure
It is necessary to regularly lubricate the chain while the saw is in use, because it works under extremely difficult conditions. Its service life is negatively affected by abrasive particles, dust and even overheating.
If you leave the chain dry, it will soon stretch and overheat. In the worst case, jamming may occur, that is, the sprocket may break. Oil is supplied through it through channels, which are often clogged with sawdust. They also need to be cleaned regularly.
In addition, constantly clear debris and sawdust from under the chainsaw cover, as this may prevent the chain brake from working. In addition, contamination has a negative impact on the performance of the device.
Starter problems
The starter fails quite often. In this case, repairing the Partner 350 chainsaw with your own hands must begin with the following: unscrew the side cover, which is located next to the gearbox. The starter for the presented saw is located near the engine. In order to inspect this part, the air damper is first removed.
Next you will need to disconnect the carburetor. The starter in this model is connected to the throttle. To separate them, you need to use a screwdriver. If carbon deposits are visible on the starter, this part will have to be completely replaced. In this case, the usual modification is installed, and finding it in the store will not be difficult. However, it is best to purchase spare parts for the Partner 350 chainsaw in specialized workshops. After replacing the starter, all that remains is to screw the throttle back on and install the carburetor with a cover.
