Minuses:

Many who have purchased the Partner 371 complain of heavy oil consumption for the chain lubrication system. In fact, this statement is not entirely relevant, since oil consumption depends on the setting set by the owner and on the quality characteristics of the product.

Star and chain problems are not an objective indicator of saw quality. These are consumables.

You can clearly see how Partner 371 copes with logs of various thicknesses, in the video, which shows that thin logs of a chainsaw are sawed quite easily, and a log thicker requires some effort.

Comparison with competitors

If the Partner 371 chainsaw is supposed to be a tool for your own site, where you need to cut thin branches, shrubs, cut firewood or file something from time to time, then it may well be considered as a good option.

If the work is supposed to be regular, or the trees under the saw cut are massive, then it is better to purchase a chainsaw adapted for this. For example, the Chinese 180th Stihl costs about 2000-3000 more, and there is no doubt about its quality. Sufficiently budgeted Husqvarna 140 or 236 also have good performance, although they are somewhat more expensive.

Partner’s classmates include chainsaws such as Champion, Patriot, Bison, Carver. All these saws are located in the segment of cheap tools. Partner and Carver among them can be safely called the best.

Note! Among Chinese chainsaws, this instance is one of the best, but it is worth treating it carefully, giving the instrument rest, and not drawing indicators higher than stated from it.

Carb adjustment

Before adjusting the carburetor, the chainsaw should be warmed up for a minute. The tool must be fully operational, as any deviation can interfere with proper operation and adjustment.

The carburetor is configured as follows. There are 3 adjusting screws on the saw carburetor:

  1. T. idle adjustment;
  2. L. low speed adjustment;
  3. H. high speed adjustment;

First of all, all three screws are tightened to the end. Immediately after tightening, “L” is unscrewed by 2 turns, “H”. by 1.5. These are average values, in the future they can be adjusted. After unscrewing the screws, the carburetor is replaced and the saw starts.

The screw “T” is gradually unscrewed on the established chainsaw. You need to let go until the moment the chain stops moving. That is, you should get a static chain on a working saw. If you feel that the traction is not enough and the tool may stall, you can add 0.25 turns to the screws.

The tuning process within the article is described very fluently, if something is not clear to you, we recommend that you read the carburetor adjustment guide on the Partner 350 chainsaw. The carburetors of the 350 and 371 models are the same, so the tuning procedure will be identical. The article discusses all the necessary aspects:

  • device and principle of operation;

Reviews

The Partner 371 chainsaw was bought for housework, mainly sawing for the firebox. Trunks with a thickness of 40 cm had to be cut, but the impressions remained mixed. After half an hour, the carburetor overheated, the chain tension regulator melted. The chain began to jump off after 20 seconds of operation. In all other respects, there were no problems.

Dmitriy

The gasoline consumption of the Partner 371 chainsaw is small, oil, contrary to expectations, does not leak. Problems were with anti-vibration springs that could not withstand vibration. Replaced, there were no problems, spare parts are freely available and the price is reasonable. After a long work, subsequently seizes far from the first time, the saw periodically needs rest. In general. not bad for a household tool, if not used for wear. I recommend it.

conclusions

It is worth acquiring a chainsaw for those whose sawing work is limited to small volumes and for those who are ready to repair Partner 371 saws with their own hands, because this tool requires a certain attention. If we consider more expensive brands, the advantage remains with them, but in the segment of cheap tools Partner is a fairly versatile, decent chainsaw capable of performing its functions.
