Chain saw is the most widely used garden machinery products, the highest frequency of power tools. Because of its sharp serration and its ability to cut wood at high speeds, more stringent safety precautions are required when working with it. Xiaobian summed up a series of chainsaw use and maintenance tips and precautions, to share with you.

First, the correct use of a reliable lubricant

It is advisable to use saw chains and guide lubricants with high quality and low environmental pollution, such as lubricants that are rapidly biodegradable and resistant to aging. If the anti-aging ability is low, the lubricating oil is easily resinified, forming difficult-to-remove hard deposits, especially on the saw chain transmission, around the clutch, and on the saw chain. Seriously stuck pump. In addition, waste oil can not be used. Waste lubricating oil does not have the required lubricating ability, and repeated exposure to waste lubricating oil may cause skin cancer, waste lubricating oil can also damage the environment.

Second, always keep saw chain lubrication

Saw chain and guide lubrication for the chain saw, it is extremely important. The technician says the saw chain must always be lifted with a small amount of oil and never work if the chain is not lubricated. If the saw chain dries, the cutting tool will soon be damaged and can no longer be repaired. Therefore, be sure to check the chain saw lubrication and the amount of oil in the tank before starting work.

Third, often check the tension of the saw chain

The new saw chain needs to be tightened more frequently than saw chains that have been in use for a longer time. Generally in the cold state, the saw chain in the lower side of the guide plate but still able to hand pull along the guide plate, then the tension is correct. After the operating temperature is reached, the saw chain expands and begins to relax. Do not allow the lower part of the guide plate drive chain out from the guide, or the saw chain will fall off. Tighten chains again if necessary. When cooling, the saw chain will shrink. At this point to adjust the loose chain, otherwise it will damage the crankshaft and bearings. Corepru chain saw adhere to choose the best parts, with imported Orleans saw chain, greatly reducing the chain saw damage to extend the chain saw life.

Fourth, do not ignore the details

Chain saw in use, there are several operational details require the user special attention.

First of all, when starting the chain saw, pull the start cord to the end. Gently pull up the start-up handle by hand until the stop position is reached, then pull it fast and press down on the front handle.

Second, after the engine has been running at maximum throttle for a long time, it needs to idle for some time to cool the airflow and release most of the heat in the engine. This will prevent thermal overload on components installed on the engine (ignition, carburetor).

Again, if the engine power is significantly reduced, it may be due to dirty air filters. Remove the carburetor cover, remove the air filter, remove any dirt on the filter, and separate the two parts of the filter. Clean the filter with the palm of your hand or blow it from the inside to the outside with compressed air. When reinstalling the air filter, remember to check that the damper and torsion spring are in the correct position.

Five, the latter part of the maintenance timely and thorough

Chainsaw maintenance, the most important is the saw chain. Correctly maintained and sharpened saw chains are easily sawn into wood with minimal pressure. Routine maintenance, pay attention to check the saw chain link on whether there are cracks and rivets. Replace any damaged or worn parts of the saw chain and then match new parts of the same shape and size. Carbide saw chain is particularly anti-wear.

For long-term storage chain saw, in a well-ventilated place to empty the fuel tank, and clean. Always operate the engine before the carburetor is dry to prevent the carburetor diaphragm from sticking together. Remove saw chain and guide plate, clean, then spray anti-rust oil. Thoroughly clean the implement, especially the cylinder cooling fins and the air filter.

Finally, we must have understood the importance of the chain saw operation. However, the most important thing is to do it. Any non-standard operation or improper maintenance may cause some potential safety hazard.
