  • Idling screw, with which you can adjust the speed of the main unit at idle. If at idle speed this screw is set to low speed, then the saw will not start, if the speed is set to high values, then the chain will start to wear out.
  • Low rotation adjusting screw. This adjustment adjusts the ideal air / fuel mixture for operating the tool at low rotation levels. If the adjustment on this screw is knocked down, then the device will not start at idle, serious problems in the engine operation are also likely (it may fail).
  • High speed adjustment screw. By adjusting this screw, the operator controls the quality of the air / fuel mixture at high rpm. Failures do not lead to wear of the saw headset and damage to parts of the main unit.

Appointment Champion 137

The chainsaw is intended for domestic use only. She can work in the country, used for cutting branches or preparing firewood for the barbecue. Champion 137 is suitable for outdoor enthusiasts as it is the lightest saw in the Champion range of household chainsaws.

The manufacturer’s recommendations on the use of this chainsaw in our country are rarely followed, and therefore Champion 137 can be found on sawmills, where a slab is cut to it. Private offices that are engaged in the procurement and sale of firewood to the population also often use this chainsaw.

Alexander. 45 years. Beloyarsk.

For more than a year and a half I have been the owner of Champion 137. I really like the saw, although I rarely work with it, only when it is necessary to prepare firewood for the barbecue and sauna. For all the time that I own this saw, she failed only once. As it turned out later, I myself violated the startup algorithm and filled in a candle. After reading the instructions, I figured out how to purge the engine after an unsuccessful start attempt and started the saw on my own, although it smoked heavily for some time, but then the exhaust returned to normal. I am satisfied with the saw.

Ivan. 56 years old. Kursk.

I bought Champion 137 after my Stihl 180 broke down, and the cost of repairs turned out to be the same as buying Champion 137. Now I’m a little sorry. As soon as you take Champion in your hands, you immediately feel the difference with Calm. The saw starts up worse when hot, it cuts worse, but I reassure myself that I paid for it almost two times less than the new Stihl 180 costs. Most likely, this saw will suit those who have not previously dealt with chainsaws.

Characteristics

Champion 137 cannot boast of excessive power or cutting speed. Compared to chainsaws in the household segment, its performance is average.

Motor power 1.55 kW, top speed 12500, this is good performance, but still some home models give a little more.

Basic setup principles

Before trying to tune the carburetor, consider the basic principles of correcting its operation.

  • The screws are easy to distinguish thanks to the marking. Adjust this or that screw when you are sure that you have correctly identified the cause of the problematic device operation beforehand.
  • Different screws need to be rotated at different operating modes of the device.
  • Only start operating the unit when you are sure that the carburetor screws are set correctly.
  • Check the optimal RPM figures listed in the instructions for your Champion saw model.

Checking acceleration work

A little research needs to be done. Device acceleration is initiated. The serviceability of the engine should be assessed during the maximum revolutions. When the engine is functioning correctly, then when you press the accelerator, the speed quickly increases to 15,000 rpm.

If this does not happen or the increase in speed is too slow, you must use the screw marked with the letter L. It turns counterclockwise. Moderate movements must be observed, since the turn cannot be more than 1/8 of a full circle.

Instruction for Chinese

To correctly configure the carburetor of a Chinese chainsaw, you must first remember the factory settings of the device, then turn on the engine. Subsequently, you will have to leave it to work for several hours in order to accurately set your own parameters. Sometimes work is performed once after ten minutes of engine operation, however, many Chinese-made models require special handling.

Chinese Chainsaw Model

  • Activities start in idle mode. With the help of the adjusting screws, you need to achieve a systematic set of revolutions by the engine, so you should first let it run at low speeds. The deviation from the norm is the movement of the chain along the tire. In this case, you need to adjust the extreme screws to the optimal position so that the chain remains stationary.
  • The transition to average speed turns is carried out. Sometimes the engine will smoke. This defect can be eliminated by tightening the screw to supply a leaner fuel mixture.

In this case, the smoke will disappear, but the engine speed will increase. It is necessary to adjust the settings until the level is reached when, when you press the throttle, the engine smoothly picks up speed, no sudden jerks or interruptions are heard.

  • The device motor is being checked. The chainsaw is moved to minimum speed, and then the lever is rapidly pressed. At maximum pressure, it is held for 3 seconds. If there is a malfunction of the engine, you need to gradually loosen the screw until the optimal position is reached.
  • The chainsaw should run for several hours under real conditions. It is necessary to engage in sawing wood, and then inspect all the elements involved in this event. If there are deviations, they must be corrected using adjusting devices. When all defects have been eliminated and optimal settings have been established for supplying correctly concentrated fuel, the process of setting up the device can be considered complete.
