49.3CC Hand Petrol Gasoline Chain Saw

Chainsaw, a handheld saw powered by a gasoline engine, is mainly used for logging and sawing. Its working principle is to use the cross L-shaped blades on the saw chain to perform cutting actions. Chain saws are a type of dismantling equipment that can be divided into motorized chain saws, non motorized chain saws, concrete chain saws, etc. based on their functions and driving methods. If the working time of a chainsaw is too long, it is easy to cause wear and tear. How should we maintain the chainsaw well?

The correct way to use a chainsaw

1. Before starting the chainsaw, it is necessary to run it at low speed for a few minutes and check the lubrication of the chainsaw chain oil and weigh the oil line before starting the work. During operation, the throttle can be set to be used at high speeds. After completing one box of oil, you need to take a break for approximately 10 minutes. After completing the work, it is necessary to clean the heat sink of the chainsaw to ensure the normal heat dissipation of the machine.

2. The air filter of the chainsaw needs to be dusted every 25 hours. In case of special circumstances, it can be adjusted by oneself. The foam filter element can be cleaned with detergent or gasoline, and then washed again with clean water, squeezed to dry, soaked in engine oil, and squeezed to remove the excess engine oil before installation.

3. When using a new chainsaw, pay attention to the tightness of the saw chain to push it to rotate. Use a hand-held saw chain with the guide teeth parallel to the guide plate. After using it for a few minutes, pay attention to observing it again and repeat this process several times.

When using a chainsaw, it is important to ensure that there are no living organisms within 20 meters of the area. Check for any hard objects, stones, etc. on the grass to ensure safety. When the chainsaw needs to be left unused, it is necessary to clean the body, release the mixed fuel, and burn all the fuel in the vaporizer; Remove the spark plug, add 1-2ml of two-stroke engine oil to the cylinder, pull the starter 2-3 times, and install the spark plug.

The cause of the problem detected by the chainsaw inspection

1. Check the oil circuit and circuit, check if the oil filter is blocked, if the carburetor is pumping oil normally, and if the spark plug has electricity. Remove the spark plug and place it on top of the metal. Pull the machine to see if the spark plug has electricity.

2. Remove the air filter and check if it is clean.

3. Remove the carburetor, then add a few drops of oil to the cylinder and start the machine a few times. If it doesn't work, you'll have to wash the carburetor or replace it, and finally check the cylinder block. Teach you a way to maintain a machine. If you don't use the machine for a long time in the future, you should pour out the oil in the tank. Start the machine and burn out the oil from the carburetor and cylinder. To prevent residual oil from clogging the carburetor, clean the air filter more often and use lubricating oil with better lubrication effect.
