Chainsaws have been extremely popular for decades. And this is not surprising, because no tool can so quickly and efficiently cope with this kind of work such as collecting firewood, cutting down trees of various sizes, etc. (see how to cut down a tree correctly).
A chainsaw not only has a high level of productivity, but also its cost is quite optimal, which almost every resident of our country can afford to pay. Undoubtedly, today there is a huge number of different models of this kind of “helpers” . This instrument is manufactured daily by various manufacturers. Read about Russian-made chainsaws in our article Russian-made chainsaws: no worse than European ones.
And each model is multifaceted and unique in its own way. But this article is intended for one of these global manufacturers of chainsaws, namely. Here you can learn not only about the company itself, but also its best models will be presented to your attention. So, let's begin.
Application
Chainsaw Lesnik 3816 belongs to the household class and is intended to perform simple tasks, such as:
- procurement of firewood in small quantities;
- tree processing;
- performing simple tasks during construction;
- cutting down dead wood.
Of course, the tool is not suitable for carving, but for all the tasks listed above, it will become an indispensable tool.
How does a chainsaw carburetor work, on what principle does it work?
Modern car engines are no longer equipped with a carburetor. Meanwhile, previously, almost every driver knew how to adjust it. Today, chainsaws with injection engines have already begun to appear on sale, but carburetor models will hold the palm for a long time, because their cost is 5-15 times lower than that of the modern version.
The carburetor consists of several main parts:
- aluminum body;
- diffuser and air damper at the inlet;
- jets (valves for regulating fuel supply);
- sprayer (it is the one that provides injection);
- fuel (float) chamber.
The operating principle of a chainsaw carburetor is quite simple. Fuel is supplied continuously, and its quantity is regulated by jets. Air enters through the air damper due to the vacuum of air created by the piston. In the diffuser, fuel and air are mixed. It is this fuel-air mixture that enters the cylinder, causing the engine to work.
Saw set
As standard, the Lesnik 3816 chainsaw has a saw set consisting of a bar and chain. The tire is 16 inches (40 cm) long, made of high-strength steel and has an increased service life.
The chain is not reliable, it hardly holds an edge, so it is recommended to immediately replace it with another one.
Forester 3816 keeps up with the times and, like all modern chainsaws, has a fast-acting emergency stop brake (activated by a special shield) and an unregulated automatic chain lubrication system.
To extend the life of the tire, it is necessary to lubricate it with oil through a special hole located in the area of the guide star. The same oil is used for lubrication as for chain lubrication.
The advantages of this model:
- selling price available to a wide range of buyers;
- classic layout of internal equipment;
- modern ergonomic body design;
- balancing and configuration of handles that promotes comfortable work from any position;
- minimum permissible level of vibration and noise impact;
- service access to setting points, air intake filter and saw chain tensioning mechanism.
The Lesnik 3816 saw, developed taking into account consumer reviews, differs from analogues identical in power and use:
- increased service life of the power unit and saw set;
- the ability for the owner to independently eliminate possible failures and malfunctions.

Equipment
The Lesnik company equips its chainsaws with a standard set necessary to get started, so when you buy a tool you will not find an additional chain or bar in the box.

- chainsaw;
- tire and chain;
- user manual;
- tire cover;
- combination key;
- warranty card.

An important nuance when choosing a chainsaw is the possibility of repairs during the warranty period at a service center. The fact is that Lesnik chainsaw service is poorly developed; not every city has service centers, so repairing a chainsaw under warranty can take a long time.
After the warranty period has expired, the Lesnik 3816 chainsaw can be repaired either on your own or in any workshop. Spare parts are freely available and are suitable for many Chinese saws, and the repair process is not as complicated as, for example, on calm saws.

If the tire does not last for the first time, it is better to throw out the chain immediately. According to numerous user reviews, it stretches like plasticine.
Engine malfunctions are very rare and in most cases are due to wear and tear or manufacturing defects. But problems with the carburetor are not uncommon.
To diagnose carburetor breakdowns, it is better to use the operating instructions; it describes all possible faults and how to eliminate them. Upon completion of the repair, the carburetor will need to be adjusted. This is not so easy to do. Our article on setting up or the same operating instructions for the Lesnik 3816 chainsaw will help with this.
About the carburetor design
The carburetor serves to mix the flammable mixture with air while maintaining predetermined proportions. If clear doses are not followed, the proper operation of the engine is at risk. When a huge amount of air enters during mixing of the components, but there is not enough fuel, then such a mixture is considered “lean”.
Oversaturation should not be allowed, because with a larger amount of fuel compared to air, malfunctions or engine wear are also likely. Carburetor adjustment is needed not only before initial use, but also when any differences in its operation are detected. Before working with a chainsaw, do not forget to run it in.
Carburetor components
The carburetor design contains a standard set of parts, but may vary little depending on the manufacturer. Components:
- The basis. This is a special tube that is visually similar to an aerodynamic design. Air passes through it. In the transverse direction, a damper is located in the middle of the pipe. Its position can be changed. The more it is extended into the passage, the less air enters the engine.
- Diffuser. This is the constricted part of the tube. With its help, the air supply speed increases precisely in the segment from which the fuel comes out.
- Channels for fuel supply. The fuel mixture is contained in the float chamber, then passes into the nozzle, from which it flows into the atomizer.
- Float chamber. It is a separate structural element, reminiscent of the shape of a tank. Designed to constantly maintain the optimal level of fuel fluid before entering the channel from which air enters.

Maximum number of revolutions
To limit this indicator, you need to use a screw marked H. To increase the number of revolutions, turn it clockwise, and to reduce them in the opposite direction. The maximum frequency should not exceed 15000 rpm.
If you make this figure larger, the device’s engine will wear out, which will lead to problems in the ignition system. When rotating this screw, you need to take into account the ignition processes of the device. If the slightest malfunctions appear, then the maximum speed value must be reduced.

I bought a chainsaw for 5,000 rubles 3 years ago. When purchasing, we tried to start it together with the manager, it started without problems. I used the saw at the dacha for two years. I built a bathhouse and often had to work with her. I threw out the chain right away, and the tire a year later. Installed OREGON. In the third year, problems began at work. Unstable operation at idle, does not pull under load, etc. I took it to the service center to see what they did to the carburetor. While I'm using it, I haven't had any other problems.
Vladimir, Barnaul
Experience using the Lesnik 3816 chainsaw for more than a year. I have already cut 20 cubes, mostly dead wood. Surprisingly, the chain and bar lasted a long time. Problems started with the carburetor. I decided to adjust it myself, it worked the first time. To set up, you only need to turn two screws in the carburetor, the whole process takes no more than 30 minutes, I think a child can figure it out.

First stage
Each model of chainsaws comes with instructions for use, which indicate all the rules for maintenance, repair, setting up the saw, as well as basic safety rules. Before you start working with the tool, you must study the manual and use it if you encounter any difficulties using the chainsaw.
If any breakdowns are detected, you can independently inspect the equipment if you have been dealing with chainsaws for a long time. If your experience is not enough to provide quality assistance and repairs, then it is recommended to contact a service center, where experienced specialists will provide qualified technical service.
Judging by many reviews, there are no particular problems in using Lesnik chainsaws. In some comments, owners point to the need to adjust the carburetor, as well as rapid wear of the bar and chain. In many reviews you can also find a recommendation to replace the drive bar and chain with products from more popular companies.
The adjusting screws for the highest and lowest speeds should be moved clockwise until the highest resistance is met. When the screws reach the stop, you need to move them in the opposite direction and leave them 1.5 turns.
