Notes 1. Before starting the gasoline chainsaw, please ensure that it fits well with the guide bar, and use a wrench to adjust the chain. When installing the guide bar, please note that the screw column on the side cover must be aligned with the guide bar hole before installation(The function of the screw column is to adjust the chain tightness.). 2. Please use gasoline 90# with special 2-cycle engine oil and never use pure gasoline. Gasoline and oil mixture ratio: 25:1. 3. Adjustment of oil output: the oil output can be controlled to turn larger to the left and smaller to the right. 4. Please note that after the first ignition sound, closing the choke and repeatedly pulling the start handle will suck in too much fuel and prevent the engine from starting.   5. If the choke knob is not fully pushed back after pulling the starter handle up to 6 times, the engine preheating may be missed. Too much fuel will flow out and submerge the spark plug. Then you can't start the chainsaw. 6. The damper is used to regulate air intake. When the engine is cold or not used for a long time, the damper needs to be pulled. If the engine is hot, it can be started directly. This is the same as the principle of starting a motorcycle! Close the damper, pull the start handle again 1-3 times to start it, and then you can use it normally. 7. Please pay attention to the tightness of the chain during installation (Pull the chain by hand. The distance between the chain and the guide plate is 3-5mm/0.12-0.2inch.), otherwise, it will affect the use effect. 8. After the chainsaw is started (The oil filler door must be empty.), it must wait for the chain to receive oil before starting to work(The oil pump will discharge oil and the ground will become wet.). 9. The carburetor must be cleaned after every 100H of operation before use. The air filter must be cleaned after 8H of operation. 10. When the chainsaw is not in use, it is better to pack it in plastic bags to avoid dust and water entering the machine and affecting its use. If the chainsaw is not used for a long time, the fuel oil in the tank must be cleaned. 11. Please read the manual completely before installation and use, and pay particular attention to the safety instructions included. 12. Please allow the slight color difference caused by the shooting light and 1-3cm error due to manual measurement, and make sure you do not mind before ordering.
