    How to adjust the high throttle of the chainsaw? The solution for the chainsaw not being able to pull
    Many people have encountered various problems with chainsaws during use and do not know how to quickly solve them.
    How to adjust the chainsaw when the throttle is weak?
    1. Leakage (crankshaft oil seal, cylinder gasket, throat, etc.).
    2. The carburetor was not adjusted properly, and the L-pin and T-pin were adjusted again.
    3. Pulling cylinder (can only be replaced).
    The reason why the chainsaw stalls when increasing the throttle while sawing wood
    1. Check if the air door is open.
    2. Check if the air filter is clean.
    3. After turning off the engine, check if there is much oil on the spark plug. If the oil can shake off, it is a problem with the carburetor. First, check the fuel supply. There is no oil or gas leakage in the oil circuit. Rotate the L-pin of the carburetor all the way to the right and then one and a half turns to the left.
    4. If it can stay at low speed and just stall at the gas door, it's a compression problem. It is possible that there is a gap between the pistons in the cylinder block or there is air leakage in the gasket on the cylinder block, which can only be repaired at a repair station.
    The method of pruning tree branches with a chainsaw
    1. When trimming, first cut off the opening and then cut on the opening to prevent sawing.
    2. When cutting, the branches below should be cut first. Heavy or large branches should be cut in sections.
    3. When operating, hold the operating handle tightly with your right hand and naturally with your left hand on the handle, with your arms as straight as possible. The angle between the machine and the ground should not exceed 60 degrees, but the angle should not be too low, otherwise it is also difficult to operate.
    4. To avoid damage to the bark, machine rebound, or the saw chain being caught, when cutting thick bark, first cut a unloading cut on the lower side, that is, use the end of the guide plate to cut a curved cut.
    5. If the diameter of the branch exceeds 10 centimeters, pre cut it first, and make a unloading cut and cutting cut about 20 to 30 centimeters at the desired cut, then use a branch saw to cut it here.
