How should gasoline saws be cared for and maintained?

A gasoline saw is a chain saw tool that uses gasoline as a power and can be used for logging or lumber. Gasoline saw chain has crisscross blades, can be repeated cutting work, strong mobility, can be held, so suitable for field mobile work, such as forestry harvesting, forest logging, splitting wood and so on.

How to care and maintain
1, check the tension of the gasoline saw chain: the chain of the gasoline saw can generate a steady stream of power for the machine, in order to better work the tool, should regularly check the tension of the gasoline saw chain, if the tension is appropriate, then the chain of the gasoline saw should be hung in the lower part of the guide, with the hand can be pulled.
2, the use of high quality gasoline saw chain lubricating oil: the chain of the gasoline saw needs to be lubrized at all times, so as not to rust or slide smoothly and affect the efficiency of use. The choice of lubricating oil must be of high quality to keep the lubricating oil not lower than the oil level, which can reduce the wear between the chain and the serration. It must be avoided that without lubricating oil, gasoline saws can never work, if too dry, it may lead to the risk of damage to the device when cutting.
3, always check the oil circuit of the gasoline saw chain: the lubricating oil in the chain saw tank should have a certain loss when in use, if the scale of the tank does not drop, there may be a problem with the oil circuit, lubrication delivery failure, so check the oil circuit of the chain, clean or replace the lubricating oil filter screen in the oil tank and pump connection pipeline in time.
4, after the replacement of the new chain, it takes 2 to 3 minutes of running-in time: the chain of the gasoline saw has a certain loss, so it needs to be replaced in time, after the replacement, it does not need to be used in a hurry, but also needs 2 to 3 minutes of running-in time, if there is no running-in, it needs to be adjusted again. In addition, the chain of the gasoline saw must be relaxed after use, because the chain will shrink when it cools, and if it is not relaxed in time, it may damage the crankshaft and bearings.

Safety precautions
1, pay attention to safety protection before use: the use of gasoline saw has a certain risk, need to wear safety protective clothing before use, wear helmet, protective glasses, gloves, work shoes and other labor protection supplies, pay attention to safety.
2, check the work before starting: the gasoline saw needs to be hand-held operation, be sure to turn off the engine when handling, before refueling also need to turn off the engine, in the state of no fuel engine, stop for 15 minutes, wait until the engine cools and then refuel, and then check the safety of the gasoline saw, confirm the safety and correct when starting.
3, the use of attention to the occasion: gasoline saw is used for logging, lumber and other tools, can not be used in a closed room, can not start the machine when smoking around, in order to prevent fire.
4, the use of attention to operation methods: the use of gasoline saw should be kept at a distance of more than three meters from the refueling site, the operation must use two hands to grasp the machine, if not firm may slip, cut and other dangers.

The gasoline of the gasoline saw is an important power for the work, should choose more than 90 unleaded gasoline, poor quality gasoline may damage the engine, seals and fuel tanks. When adding gasoline, the oil tank cap and the surrounding area of the refueling port must be clean and clean to avoid debris entering, and can not put the tank tank too slowly. After adding oil, you must tighten the oil tank cap by hand.
