Chainsaw “Partner” 350 is a productive and reliable chainsaw from the “Partner” brand.
This manufacturer is part of the group of companies of the Danish concern Husqvarna, which significantly influenced the quality and functionality of the equipment it produces. Easy to operate and convenient, this chainsaw will be useful for summer residents and gardeners. And the low weight and compactness do not create restrictions for transporting the tool.
Functionality and technical characteristics of the Partner 350 S chainsaw
The modification of the chainsaw under consideration has a modern design and decent ergonomic and performance characteristics. A diagram of the external device of the Partner 350 chainsaw is shown below.
According to the detailed diagram, the “Partner” 350th model chainsaw consists of:
- cylinder hatch;
- front handle;
- saw section hand brake lever;
- starter cover;
- crankcase;
- starter cable;
- throttle control lever;
- air damper;
- rear handle;
- ignition switch;
- gas tank;
- muffler;
- tire sprocket;
- chain;
- tire;
- guide fasteners;
- blade catcher;
- clutch cover;
- right hand safety;
- throttle lever;
- throttle stop;
- universal key;
- saw set tensioner;
- primer
The power component of the device is a single-cylinder 2-stroke engine running on a fuel mixture. A reinforced piston group, a large torque reserve, and an effective air cooling system extend the service life of the device. With a cylinder volume of 34 cm3 and a piston stroke of 3.2 cm, the chainsaw generates a rated power of 1.3 kW. This is enough to create high cutting speeds in both horizontal and vertical directions.
Buying a tire is not an easy task
When purchasing a tire that is different from the original model, there is a high probability that the old chain and the new tire will not fit together in any way. The ideal option: try on all three key components - the tire/chain pair and, in fact, the gas-powered tool itself. A slight difference, sometimes not even noticeable to the eye, of just one link can be critical for the entire assembly: the chain either won’t fit at all or will sag.
The next point: different chainsaws are designed for different widths of tire grooves, and accordingly, the drive links are designed for use with different tires. The wide grooves of the chainsaw are designed for a chain that can withstand significant loads, characterized by high quality workmanship and operating efficiency. When choosing a chain, it is important to check the possible width for a given chainsaw model.

It is important that the number of links does not fall within the range of 46-52 pieces.
How to prepare a chainsaw for work?
Before you start working with a chainsaw, you need to make some settings on the unit. A properly prepared device will never cause any complaints from users. Setting up a chainsaw is quite simple. Before starting the tool motor you need to check:
- serviceability of the brake;
- chain tension and ease of rotation;
- presence of oil and fuel in the unit;
- tire mount.
After the check, you need to start the engine. Warm it up well and feel free to get to work.
Setting up the Partner 350 chainsaw
According to the operating instructions, before starting the Partner 350 chainsaw, it undergoes special training, which includes:
- installation of the saw set or checking its tension for already installed parts;
- checking the serviceability of the brake band;
- placing the brake handle in a ready state as shown in the figure;
- filling the oiler and gas tank with fuels and lubricants. The fuel mixture is prepared in a ratio of 1:50 from oil for 2-stroke engines and unleaded gasoline AI-92.
The launch is carried out on a flat surface, sharply pulling the throttle cable. During a cold start, open the air damper and allow the chainsaw to warm up. Only after this can you gain momentum and move on to woodworking.
All possible nuances of adjusting the Partner 350 chainsaw with your own hands are described in detail in the operating instructions. If they are not followed, the instrument is not insured against malfunctions and repairs, the budget of which may be unpredictable.
Classification of saw bars
A saw set refers to the working elements of a chainsaw, which are intended for direct cutting: a chain and a bar.
One of the points that influence the choice of a particular model is the type of tire and its length. Saw bars for chainsaws are classified as follows:
- narrow flat - works in tandem with a low-profile chain of a non-professional household chainsaw, minimizes the risk of injury due to the virtual absence of the “kickback” effect, which is especially important for chainsaw beginners;
- lightweight - made of two steel plates connected by a polyamide layer. This design significantly reduces the overall weight of the chainsaw itself, which can serve as a serious advantage when performing certain types of work;
- bar with replaceable head - installed on professional chainsaws of medium and high power, used for a large volume of long-term work.
Tire type is a serious characteristic, but not the only one that needs to be taken into account when purchasing a chainsaw.
Chainsaw “Partner” 350 malfunctions and their elimination
The most vulnerable systems of the 350th chainsaw from the Partner brand are:
- motor part;
- ignition system;
- lubrication supply problems.
Diagnosis of engine failures
If the engine stalls or does not start at all, the reasons may be the following:
- lack of gasoline or air supply;
- there is no spark to ignite.
For a more accurate analysis of the situation, you need to:
- make sure that the fuel reaches the carburetor part - if not, then: the saw’s gas tank is empty:
- the float needle is clogged;
- air access to the fuel tank is stopped;
- The gasoline filter is clogged. These breakdowns can be eliminated by cleaning the cleaning systems and refilling the chainsaw with high-quality fuel.
- If it does not spark after connecting to a grounded wire, the problem is with the spark plug itself and will likely need to be replaced. In addition to the spark plug, other spare parts often fail - the ignition coil or switch;
- detecting a wet spark plug is a sure sign that the spark plug is flooding. This may be due to:
- incorrect or failed carburetor factory settings;
filling the carburetor block with fuel.,
In any case, it is necessary to update the carburetor settings.
Carburetor adjustment
If the “Partner” chainsaw does not start well, smokes heavily and does not produce the power specified by the manufacturer, the question of how to adjust the carburetor of the “Partner” 350 chainsaw should become central to every user. To solve it:
- warm up the engine;
- tighten screw L until it stops, then loosen it by a quarter;
- if the saw continues to stall at idle, turn the T jet;
- For correct operation of the “Partner” chainsaw under load, use screw H to achieve maximum speed.
For installation, it is advisable to have a universal key and a tachometer (crankshaft rotation counter) on hand. Carburetor installation and ignition adjustment are still performed. Therefore, there is no need to reconfigure a completely new saw.
Oil supply system malfunctions
The situation when chain lubrication involuntarily flows out of the chainsaw body and does not reach the cutting parts does not indicate the need to repair the oil pump, clean the oil supply pipes, or replace them with serviceable spare parts. In addition, lubricant drips may indicate depressurization of the connection between the pipes and the oil sump. If these breakdowns are not corrected in time, the chain will begin to overheat, stretch and fail prematurely.
Do-it-yourself repairs to the Partner 350 chainsaw should only be carried out by people who understand its structure and operating principle. Only in this case can we hope that the replacement of the drive sprocket or crankshaft will be carried out correctly and safely for further work.
Selecting the bus length based on drive power
The length of the new guide bar is determined by the power and torque coefficient of the power unit.
- Models of chainsaws in the small and medium power range are equipped with tires with a length of 30 to 40 cm.
- Longer saw sets create excessive loads on the engine and kinematics of the tool, which negatively affect its traction characteristics and service life.
- Please see the enclosed instruction manual for the recommended length of the guide bar. This means that installing a shorter headset is not excluded, but there are a number of restrictions on the operation of the instrument with an extended length bus.
Professional-level chainsaw equipment is equipped with power units whose power allows you to take advantage of tires up to 75 cm long. Often the tire size in centimeters and inches is marked on its side plane.
Advantages of a chainsaw
Like any other product, a chainsaw has its advantages and disadvantages. First, let's talk about the advantages of the device:
- The unit is produced at the plant of a well-known manufacturer. This can only speak about the quality of the chainsaw and the developed product maintenance service.
- The chainsaw engine is equipped with a primer, which makes starting the unit easier. In the cold season, primer is an indispensable element of a chainsaw.
- The engine cylinder and piston are treated with chrome. This is done in order to improve the performance of the product and extend the service life of the chainsaw as a whole.
- The chainsaw is lightweight and has a short bar - this makes working with the device much easier.
Disadvantages of a chainsaw
The chainsaw has its disadvantages, but compared to the advantages they do not look so significant. The disadvantages of the product include the following:
- Difficult access to the air filter.
- There is no visual control of the lubricant level.
- If you install a long tire, you may notice low engine power. But this phenomenon is considered natural. The longer the tire, the less engine power.
Sometimes chainsaw users report poor performance of the unit. In this case, it is worth considering whether a double violation has been committed - ignoring the requirements of the chainsaw operating instructions and placing additional load on the engine of the unit.
