is one of the most widely used and frequently used power tools in garden machinery products. Because it has very sharp teeth and is used for high-speed cutting of wood, strict safety precautions must be taken when using it. Afterburner summarized a series of chain saw use methods and maintenance skills and precautions, to share with you.
1. Use reliable lubricant correctly
It is recommended to use high-quality, low environmental pollution saw chain and guide plate lubricants, such as lubricants with strong anti-aging ability and rapid biodegradation. If the anti-aging ability is low, the lubricating oil is easily resinized, which will form hard deposits that are difficult to remove, especially around the chain transmission parts, clutches, and chains. In severe cases, it will jam the oil pump. In addition, do not use waste lubricants. Waste lubricating oil does not have the required lubricating capacity, and repeated contact with waste lubricating oil may cause skin cancer, and waste lubricating oil will also damage the environment.
Second, always keep the saw chain lubricated
The lubrication of saw chains and guide plates is extremely important for the use of chain saws. The technician said that the saw chain must always have a small amount of lubricating oil thrown out, and never work without saw chain lubrication. If the saw chain runs dry, the cutting tool will soon be damaged and can no longer be repaired. Therefore, be sure to check the lubrication of the saw chain and the amount of lubricating oil in the oil tank before starting work.
3. Regularly check the tension of the saw chain
Compared with chains that have been in use for a long time, new chains need to be tightened more frequently. Generally, in the cold state, the saw chain is engaged on the lower side of the guide plate, but it can still be pulled along the guide plate by hand, which means that the tension is correct. After reaching the working temperature, the saw chain expands and begins to relax. The drive link on the lower side of the guide plate is not allowed to come out of the guide groove, otherwise the saw chain will fall off. If necessary, tighten the saw chain again. When cooling down, the saw chain shrinks. At this time, loosen the saw chain, otherwise it will damage the crankshaft and bearings. Krip oil saw insists on choosing the best accessories, equipped with imported Origen saw chain, greatly reducing the damage of the saw chain and extending the service life of the saw.
Fourth, the details not to be ignored
During the use of the chain saw, there are several operating details that require the user's special attention.
First of all, when starting the chain saw, do not pull the start rope to the end. When starting, gently pull up the starting handle until it reaches the stop position, and then quickly pull firmly while pressing down on the front handle.
Secondly, after the engine has been running at maximum throttle for a long time, it needs to be idle for a period of time in order to cool the air flow and release most of the heat in the engine. This can avoid thermal overload of the components (ignition device, carburetor) installed on the engine.
Again, if the engine power drops significantly, it may be caused by dirty air filters. Remove the carburetor box cover, remove the air filter, remove the dirt around the filter, and separate the two parts of the filter, dust the filter with the palm of your hand, or use compressed air to blow out from the inside out. When reinstalling the air filter, remember to check the correct position of the damper and torsion spring.
Fifth, the later maintenance is timely and thorough
The top priority of chain saw maintenance is the saw chain. A properly maintained and sharpened saw chain can be easily sawn into wood with little pressure. During daily maintenance, pay attention to check the chain links for cracks and broken rivets. Replace any damaged or worn parts on the saw chain, and then match new parts with the same shape and size. Carbide saw chains are particularly resistant to wear.
For long-term storage of chain saws, the fuel tank must be emptied and cleaned in a well-ventilated area. Always run the engine before the carburetor dries to prevent the carburetor diaphragms from sticking together. Remove the saw chain and guide plate, clean them, and spray with anti-rust oil. Clean the machine thoroughly, especially the cylinder cooling fins and air filter.
Finally, everyone must understand the importance of chain saw operation, but the most important thing is to do it. Any irregular operation and untimely maintenance may cause certain safety risks.
