Why is it so important to file a chain?
In the garden tools, we commonly refer to the oil saw accessories with crankshaft, saw chain, piston, air filter, cylinder, crankcase, muffler, high pressure package, magnetic flywheel, etc.
Chain saw saw chain is made up of sawtooth, transmission chain, connecting pieces and chain axis rivet with sawtooth closed chain, due to the work after a period of time, saw chain tooth blade dull, saw cutting efficiency to reduce, therefore to rasp, saw chain often should accord with standard of saw chain, generally should file once every 4 hours, the poor quality of saw chain are often file.
The quality of the file grinding is very important to the service life of the chain, the normal use of the oil saw and the productivity of sawmill.
In file grinding, the standard of Angle is very difficult to master, generally can be measured according to the triangle rule, if have Angle gauge is even better.
Usually experienced oil sawers are based on the size of the sawtooth climbing edge to master the appropriate Angle. By grasping the rule of the sawing chain, the quality of the sawing chain can be improved rapidly.
The tooth height of the saw is related to the service life of the saw chain.
Don't malicious file, so in the chain of file thin file to a layer of metal, especially after the climb edge blade don't often file, also do not malicious file, or it will lower the depth and dial the shoes quickly, chain saw saw chain will be scrapped soon.
If you want to make the teeth of the saw chain high, the material width and the climbing edge are smooth, you must first try the sawing chain. After sawing the wood, if you find that you need to file it, you will need to file it again.
Why is it so important to file a chain?
The file mill of the oil saw chain can be filed with a file by hand, or it can be filed with a file saw machine.
In order to reduce the consumption of manpower and improve the efficiency and quality of sawing chain, it is necessary to widely promote the use of file sawing machine.
The commonly used hand file mainly has board file, knife file and round file.
Flat file and knife file are common files used for file grinding and straight teeth sawing chain.
The round file is mainly used for filing the universal chain.
The teeth of the straight - tooth saw chain are best used round file.
Triangular files are not commonly used.
When the file is filed, the file should be stable, the wrist should be hard, and the eye saw the point.
File before saw, will file on the sawtooth first, by the tooth positions below push up at an Angle, not the back file, in order to avoid damage to the file, and file the slope should agree, file should change at any time, so as not to damage the file due to overheating.
In order to ensure the quality of the sawing chain, some oil saws are provided with special tools at the time of sale.
Such as cory's chain saw the attached "test chain rules", use it can test with limited level blade Angle of elevation difference and sawtooth elements, difficult tip of the chain rule, also can be used to clean up the groove and oil hole for sawing plate.
In addition to the sawing chain, check the tension of the chain.
The new saw chain needs to be tightened more frequently than the long - time saw chain.
Generally, under the condition of cold machine, the chain is meshed under the guide plate but still can be pulled by hand along the guide plate, which indicates that the tension degree is correct.
After reaching the working temperature, the saw chain expands and relaxes.
The drive chain section under the guide plate is not allowed to come out from the guide slot, otherwise the chain will fall off.
Tighten the saw chain again if necessary.
When it cools, the chain shrinks.
At this point, you should loosen the saw chain, otherwise it will damage the crankshaft and the bearing.
Saw chain as an important part of the garden machinery oil saw, it is very important to take the maintenance of saw chain seriously.
