Chainsaw, short for "gasoline chainsaw" or "gasoline-powered saw". A power saw was used for logging and lumbering. The cutting mechanism is the chain. Powered by a gasoline engine. Portable and easy to operate. But maintenance and repair is more complex.

Chainsaw is a two-stroke power, the use of power, cutting tools and other aspects of attention to ensure the normal use of the machine: the engine is a two-stroke engine, the use of fuel gasoline and oil mixture, mixture of oil ratios are: two-stroke special oil: gasoline = 1:50 (ordinary oil: gasoline = 1:25). The gasoline is 90 or above, and the oil is two-stroke oil, the symbol is 2T, must use the famous brand special oil, forbid to use the four-stroke oil. It is recommended that the new machine in the first 30 hours with 1:40 (ordinary oil 1:20), 30 hours after the normal ratio of 1:50 (ordinary oil 1:25) with oil, resolutely do not allow more than 1:50 (ordinary oil 1:25), otherwise the concentration is too thin will cause the machine to pull the cylinder. 

Please strictly according to the machine comes with the oil distribution pot oil distribution, not according to the estimation of random oil distribution. Mixed oil is best to use now, is strictly prohibited to use with a long time to set up the mixed oil; machine before work, the first low-speed operation for a few minutes to see the lubrication of the saw chain oil, into a line of oil, and then work. When the machine is working, put the throttle on the high speed. After each tank of oil, should rest for 10 minutes, after each work to clean up the machine's bulk gasket, to ensure heat dissipation; spark plugs should be removed every 25 hours of use, with a wire brush to remove the electrode on the dust and dirt, adjust the electrode gap to 0.6[1]-0.7mm for good; air filter every 25 hours of use to remove dust, dust should be more frequent. Foam filter element cleaning using gasoline or washing liquid and water, squeeze and cool dry, and then soaked in oil, squeeze the excess oil can be installed. If printed & ldquo; DON NOT OIL & rdquo; do not need to add oil; muffler every 50 hours of use, remove the muffler, clean the exhaust port and muffler outlet on the carbon. Fuel filter (suction head) should be cleaned of impurities every 25 hours.

Cutting tool part of the new machine, should pay attention to the degree of tension of the saw chain, in order to be able to promote the rotation of the saw chain, hand-held saw chain, guide teeth and guide plate parallel to the appropriate, after a few minutes, pay attention to the tensioning of the saw chain again.

Before using the safety work, no people or animals are allowed to walk around within 20 meters. Be sure to check whether there is no angle iron, stones and other debris on the grass, remove the debris on the grass.

Storage Storage, you must clean the body, drain the fuel mixture, the carburetor fuel burning clean; remove the spark plug, add 1-2ml of two-stroke oil to the cylinder, pull the starter 2-3 times, install the spark plug

Chainsaw troubleshooting

Chainsaws in large quantities in domestic sales, popularization and application in 2000, the most well-known imported brands such as Gongli, Komatsu, domestic brands are mostly imitation of the production of imported brands, which also led to the domestic industry in the industry there is no uniform standard. Domestic chainsaw due to the selection of materials and technology gaps, so product quality is far less than the original imported brands, the price has become the biggest competitive advantage of domestic brands.

1. if the senwart chainsaw appeared to refueling stalled, work less energetic, heating machine overheating and other phenomena, is generally a filter problem. So before work, the need to check the filter, clean and qualified filters aligned with the sunlight observation, it should be thorough, bright, and vice versa unqualified. Chainsaw filter is not clean enough should be washed with hot soapy water, dry. Clean filter to ensure the normal use of chainsaws.

2. Pake when the saw teeth of the chainsaw becomes not sharp, you can use a special file on the saw teeth chain cutting teeth to rest, to ensure that the sharpness of the saw teeth. At this time, it should be noted that in the file to thwart the time, along the direction of the cut teeth to thwart, not against, while filing and chainsaw chain saw chain angle should not be too large, was 30 degrees is appropriate.

3. 3 in the use of chain saws, should be filled with chain saw chain oil, the benefits of doing so is to be able to provide lubrication for the chain saw, reduce the chain saw chain and chain saw guide plate friction heat, play a protective role in the guide plate, but also to protect the chain saw chain, so as to avoid premature obsolescence.

4. Singed when the end of the use of chain saws, but also to carry out some maintenance on the chainsaw, so that the next time you use the chain saw to ensure efficiency. First of all, remove the chain saw guide plate root oil inlet holes and guide plate groove impurities, to ensure that the oil inlet holes are smooth. Secondly, the guide plate head should also be clear of debris, and add a few drops of oil.
