distinctive features

This model belongs to the domestic class, that is, it should be used by non-professionals. Nevertheless, it is equipped with a powerful (2.3 hp) two-stroke engine, which develops enough high revolutions. Japanese carburetor – Walbro, has proven itself only from the good side.

The body is made of high quality plastic, which can withstand heavy loads, but can still break. There is chain breakage and rebound protection – this makes the tool safe. For safety, there is also a button that blocks accidental starting of the starter. The piston and cylinders are nickel plated to resist corrosion.

Unpacking and getting ready to use

When buying a Huter bs-52 chainsaw, we advise you to carefully inspect the tool for visible defects and damage. In addition, we strongly recommend that the seller perform a test run of the engine to make sure it is working properly.

The Huter bs-52 chainsaw comes assembled, the new owner must assemble the saw set:

  • Remove the side protective cover by first unscrewing the two mounting nuts;
  • Insert the saw bar shaft into the slotted seating;
  • Put the chain on the drive wheel and insert it into the guide bar grooves;
  • Install safety guard with inertia brake lever and secure with nuts;
  • adjust the chain tension;

Ensuring safety during sawing work

The saw is also equipped with a 350 mm long bar, which is set for more comfortable work in hard-to-reach places. A toothed stop ensures that the tool is securely fixed when sawing logs. Chain voltage is set with the special wrench included in the kit.

For increased safety the saw has an emergency stop device combined with a safety shield. In the event of an abnormal situation, the movement of the chain along the bar is blocked almost instantly by a slight forward movement of the guard.

carburetor adjustment

The Huter BS 45 and Huter BS 52 chain saws have a membrane carburetor that can be used to adjust the quality and amount of mixture. After purchasing the tool, it is recommended that the fuel mixture be easily injected to compensate for the stresses that occur during the piston grinding process.

The screw (L) is responsible for the fuel mixture quality. To enrich the fuel mixture (increase fuel supply to the cylinder), turn the screw a quarter turn counterclockwise. After entering, return to the original position.

If the carburetor of the saw is fully adjusted, it is adjusted according to the following algorithm:

  • If the saw is inserted, the L and H screws are set 2.5 turns fully dressed;
  • The saw starts up and warms up for 5-10 minutes;
  • After warming up, slowly dial the L screw to find the maximum idle speed and then release the screw a quarter turn.
  • The H screw adjusts the engine at maximum RPM;
  • After setting the L and H screws, set the idle speed with the T screw. They should be set so that the engine runs steadily and the saw chain does not turn.

Important: The maximum speed must be adjusted with a tachometer. If there is no such a device, the screw is set to the moment when the engine starts to work smoothly and monotonously and easily gain speed

It should be remembered that carburetor adjustment should be carried out only after a complete diagnosis of the saw and the elimination of such irregularities as reduced pressure in the crankcase, air leakage under the spark plug and carburetor sealing.

advantages and disadvantages

The main advantage of the BS 45 and BS 45m chainsaws is their cost, which is almost half that of the competitor’s chainsaws. You can check this by looking at offers from Yandex with approximate prices.

Another positive point is the availability of warranty and re-warranty service. Hauter craftsmen are specially trained, so you can count on quality when repairing the saw.

From a technical point of view, the advantages of these chainsaws are high performance and long bars, with which you can easily cut thick trunks of trees.

Another plus is the availability of spare parts. If you are used to repairing the saw yourself, you will be pleasantly surprised by the fact that spare parts for the Hauter BS 45 and your modification are sold in almost all specialized stores for gas devices.

The disadvantages of these chainsaws are not many, but they are quite significant.

  1. The quality of assembly (you have to tighten the screws after purchase).
  2. The plastic parts are of low quality.
  3. Fuel and oil tank caps are quickly consumed and begin to slip (replacement is not difficult, but cumbersome and tedious).
  4. Low engine life due to the poor quality of the parts that make it up.
  5. Weight. The BS 45M (BS 45) chain is difficult to work with for a long time. Especially when it is necessary to saw small shoots.

All the disadvantages of a chainsaw are directly related to its cost. If they are eliminated, it will cost much more.

Problems of self-repair

The problem in many cases is complicated by the lack of complete information about the technology of repair. According to foreign manufacturers, after working out the saw should be scrapped, so the repairability of many budget models raises reasonable doubts.

To restore a professional-class chainsaw is much more difficult.

  • The problem is complicated by the high cost of spare parts.
  • It is possible that to restore the performance of individual nodes and mechanisms, in particular, you will need special equipment to adjust the fuel equipment.

The manufacturer recommends the use of adhesive oils from well-known manufacturers:

  • HUTER 80W90;
  • Husqvarna chain oil;
  • Oleo-mac polar grease;
  • mannol chain oil;
  • Liqui Moly brew-kindten;

Design advantages

Attention of the user:

  • Ergonomic handle configuration for a secure grip on the tool during demanding jobs.
  • Effective emergency brake and easy access to chain tensioner;
  • Moderate, in the range of 7 kg, weight that allows the worker to maintain high productivity throughout the entire work layer.

The good maintainability of the saw makes it possible to fix failures and malfunctions in the factory without involving the service department. The enclosed instruction manual contains information to help avoid mistakes in setting up the fuel system, functioning headsets, and other systems of the tool.

Interference with the fuel system must have a good reason. In most cases it is the switch of the tool to winter or summer operation, switch to fuel with a different octane number, noticeable changes in the traction properties of the engine.

A correctly adjusted carburetor promotes quick engine starting, stability of its tractive properties in all operating conditions and economical fuel and oil consumption.

What do you talk about on forums?

Vyacheslav Poznyakov, 32, Ulyanovsk region:

I live in the countryside, it is impossible here without a chainsaw: and you need to make firewood, and repair, and the garden to stir up. I have been using this model for four years. I can say that Huter BS 45 chain saw consists of high quality components, has an effective anti-vibration system and a reliable engine. I analyzed the clutch – all parts are made of high quality materials, the drive star remains native, there are no special developments. Of the disadvantages – too much weight, even taking into account the power of the engine.

Ruslan Nikonov, 38, Altai region:

Bought a chainsaw Huter BS 45 and realized that I am buying a Chinese, albeit from a well-known brand. In general, my hopes and fears were justified. The tool is made quite well and has a good engine, though it does not have all the features I expected. The body of the saw is well balanced, but the weight is too much. The saw is fairly flat, the bar is of good quality, but the chain is quite weak – I threw it away after a month. In addition (as I understand, this is the source of this model), I had oil leaking from the oil tank – the quality of the plastic does not stand up to criticism.

Advantages: price, good build, reliable motor, quality vibration system;

Disadvantages: weight, weak chain in the set, poor quality plastic on the oil tank, the motor is required all the time.
