    Chainsaw "Partner" 350: device, characteristics, DIY repair

    Chainsaw "Partner" 350. 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 come in handy for summer residents and gardeners. And low weight and compactness do not create restrictions for transporting the tool.

    Chainsaws Partner (Partner) 350

    Popular among gardeners, the Partner 350 chainsaw successfully combines endurance, the ability to cope with the most difficult household tasks and economy. This model tolerates operation well in difficult weather conditions, which makes it possible to use it both in summer and winter, without the risk of unexpected breakdown of the main working units

    Chainsaw Partner 350 starts up and stalls

    There may be several reasons for this malfunction. Most often, the engine of the tool starts up and immediately stalls due to a clogged factory breather, as a result of which fuel does not enter the engine cylinder in sufficient quantity for operation. To fix the damage, you will need to remove and clean the breather. If it is damaged, then it will need to be replaced.

    Another reason is the missing contact of the spark plug with the electrical wiring cap. This can be due to mechanical shock or engine oil carbon deposits on the plug. To repair the Partner 350 chainsaw, the spark plug will need to be removed and cleaned. In some cases, a complete candle replacement can help.

    The third reason for the malfunction is a strong blockage of the standard chain saw muffler. Over time, carbon deposits form on its walls, which prevents exhaust from the engine. As a result, gases build up inside the motor and interfere with proper operation. To fix the damage, it is necessary to remove the muffler and clean it with compressed air. You will also need to disassemble the motor and blow out its cylinder.

    Adjusting the carburetor of the Partner 350 chainsaw with your own hands

    Before you start tuning the standard Partner carburetor, you need to thoroughly clean it from dust, dirt and carbon deposits that have accumulated on the walls. In addition to the carburetor, you will need to rinse and dry the fuel and air filters. Otherwise, the operator will not be able to accurately set the required engine speed.

    In the upper left part of the protective plastic case of the Partner saw there are holes, inside of which the manufacturer provides bolts for adjusting the carburetor. Having found them, you can proceed to the basic configuration of the node. To do this, the left and right screws, which are responsible for the number and quality of turns, respectively, must be set to the fully tightened position. They must be loosened immediately afterwards by 1/5 of a turn. The third adjusting bolt, marked T, must be left in the position in which it is installed.

    The final setting of the carburetor of the Partner 350 chainsaw is performed in the following order:

    • First, you need to start the saw and let its motor run to fully warm up;
    • After 5 minutes, you can start adjusting. First, the left bolt must be turned in the direction of the clock hand until the engine reaches maximum speed. Then the left bolt must be turned 1.4 turns in the opposite direction. After completing these steps, the engine of the Partner chainsaw should work confidently at idle;
    • If, after manipulating the left adjusting screw, the chain on the bar begins to rotate, then it must be stopped by alternately turning the bolt T;
    • Then you need to proceed to setting the quality of the fuel mixture. To do this, the right adjusting screw will need to be turned in the same direction as the clock hand. As soon as the motor reaches the maximum permissible speed, the screw must be unscrewed 1/4 turn in the opposite direction.

    When setting the maximum engine speed for the Partner 350, it is better to use a tachometer connected to the motor. As soon as the device shows the same rpm as indicated by the proprietary operating instructions for the model, it means that turning the screw must be stopped.

    What to do if the chain on the Partner 350 chainsaw is not lubricated?

    If the chain for the Partner 350 chainsaw is no longer lubricated with oil, this can lead to overheating of the bar and rupture of the saw headset. Ignoring this problem can also lead to increased engine load, which can lead to engine failure.

    The first thing to inspect if there is no lubricant on the chain is the oil pump. Over time, the teeth on its drive wear off, which can also happen due to a clogged pump. The element is usually impossible to restore, so it is best to replace it.

    Often, lubricant does not get on the chain of the Partner 350 chainsaw due to clogged oil pipes. In this case, the hoses will need to be replaced by treating their joints with the fittings with a sealant.

    Chainsaw Partner 350. ignition adjustment

    If the Partner 350 saw stops starting, then you need to check the condition of the plug and the ignition system. To do this, you need to unscrew the part and inspect it. If it is clean with small light spots, then you need to adjust the ignition system of the tool.

    Next, you need to check the voltage of the high-voltage cable. For this we use a light bulb or probe. In the absence of voltage, the problem is a wire break. If it is intact and not broken anywhere, then you need to adjust the gap in the ignition system of the Partner 350 model.

    To adjust the clearance, turn the 2 side bolts located next to the handwheel of the tool. As a result, the flywheel will move away from the ignition coil. After that, you will need to install a probe between the parts, and turn the side bolts in the opposite direction. The handwheel should move closer to the coil. At the end, you need to carefully remove the probe and assemble the saw.
