Use and maintenance
The chain saw is a two-stroke power, you should pay attention to power, cutting tools, etc., to ensure the normal use of the machine: the engine is a two-stroke engine, the fuel used is a mixture of gasoline and engine oil, and the ratio of the mixed oil is: air-cooled two Special-stroke engine oil jaso fc grade: gasoline=1:50 (air-cooled two-stroke special engine oil jaso fb grade: gasoline=1:25).
Gasoline should be above No. 90, and the engine oil should be air-cooled two-stroke engine oil, the symbol is 2t, and brand-name special engine oil must be used. Four-stroke engine oil or water-cooled two-stroke engine oil is strictly prohibited. It is recommended that the new machine be equipped with 1:40 (jaso fb grade oil 1:20) in the first 30 hours, and the normal ratio of 1:50 (jaso fb grade oil 1:25) after 30 hours. It is strongly not allowed to exceed 1:50 ( Ordinary engine oil 1:25), otherwise the concentration is too thin will cause the machine to pull the cylinder.
Please dispense oil strictly according to the oil dispenser attached to the machine, not arbitrarily according to estimates. The mixed oil is best prepared for immediate use. It is strictly forbidden to use the mixed oil that has been used for a long time; before the machine works, run it at low speed for a few minutes to see the lubricating chain oil, form an oil line, and then work. When the machine is working, place the throttle on the high speed use. After each tank of oil work, you should rest for 10 minutes. After each work, clean the loose gasket of the machine to ensure heat dissipation; remove the spark plug every 25 hours of use, brush off the dust on the electrode with a wire, and adjust the electrode gap to 0.6 [1] -0.7mm is better; the air filter removes dust every 25 hours of use, and the dust should be more frequent. The foam filter element is cleaned with gasoline or washing liquid and clean water, squeezed to dry, and then soaked in oil, squeezed out the excess oil to install.
Every 50 hours of use of the muffler, remove the muffler and clean up the carbon deposits on the exhaust port and muffler outlet. The fuel filter (suction head) removes impurities every 25 hours.
When using the new machine for the cutting tool part, pay attention to the tightness of the saw chain so that it can push the saw chain to rotate. It is advisable to use a hand-held saw chain with the guide teeth parallel to the guide plate. After a few minutes of use, pay attention to tensioning the saw chain again.
Before using the safe operation, no people or animals are allowed to move within 20 meters. Be sure to check whether there are angle irons, stones and other debris on the grass, and remove the debris on the grass.
Storage When storing, you must clean the body, let off the mixed fuel, and burn 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
Chain saws are sold in large quantities in China, and they have been widely used since 2000. The most well-known imported brands include Stihl, Husqvrna, etc. Domestic brands mostly imitate imported brands, which has also led to domestic There is no uniform standard in the industry. Due to the gap in material selection and process technology for domestic chain saws, although the product quality is not as good as the original imported brands, some well-known domestic manufacturers, such as Zhongjian, etc., have formed a strong catch-up trend after years of accumulation, and the prices are also domestic brands. The biggest advantage of competition.

Precautions
1. The recommended fuel mixing ratio is 50:1 to 25:1 (high-quality air-cooled two-stroke engine oil must be used for mixing), and 10%~30% diesel (kerosene or light oil) should be added to the lubricating oil of the saw chain. ) Use after mixing to ensure proper concentration. The proportion should be determined according to the amount of oil sprayed by the saw chain and the degree of addition, but should be controlled within the range of 10% to 30%.
2. The idling speed should be adjusted according to the actual situation of the machine. The idling speed range is generally: 2800~3500 rpm. Special attention should be paid to the fact that 1.25 times the idling speed of the machine should be less than the clutch speed of the machine ( The engine speed when the saw chain starts to run). Generally, two-stroke machinery fuels are mixed with steam engine oil (the engine oil is the special engine oil for two-stroke engines), and the ratio is standard. The ratio of steam to engine oil is about 25:1, depending on the usage. If it is not used for a long time High-speed operation can increase the concentration appropriately. If the high-speed operation is often maintained during use, the concentration should be appropriately reduced, and more oil should be added to ensure the normal lubrication of the internal running parts of the cylinder, but the muffler should be removed in time to clear the exhaust The carbon deposits in the channel can prevent excessive carbon deposits from entering the cylinder body and causing cylinder pulling.
