38 SD7-154 Chainsaws Sprocket Metal Injection Molding

Chainsaw files are also called chain saw files, chain saw steel files, etc., and are commonly used in chain saw accessories. Files have been used for a long time. The oldest file found is a bronze file from Egypt around 1500 BC. Chain saw files are used in large quantities and have high quality requirements. Although the chain filing speed is not as fast as the chain grinder, it is easy to carry and cheap. The chain filing effect is better than that of an electric chain grinder, and the maintenance loss of the chain saw chain is lower than that of a chain grinder. It can be said that it is one of the necessary chain saw accessories in the tool bag of lumberjacks using chainsaws. So how to use a chain saw file? In addition, the chain saw sprocket is used as a power transmission intermediate for the passive disk and chain, and because of its high working intensity and high loss, it needs to be replaced more frequently. Someone will ask about the chain saw. How to replace the sprocket? Today, I will mainly tell you how to use the chain saw file and how to replace the chain saw sprocket.

How To Use The Chain Saw File

The chain is easy to wear and needs regular maintenance. When filing the chain saw chain, it is best to fix the chain first. The chain saw chain can be placed directly on the chain saw guide plate, and then the chain saw file is pulled back along the cutting direction of the blade (one-way). Generally, the chain saw chain maintenance can be completed in about ten minutes. In order to make the chain saw file more convenient to use, it is best to use it with a chain file handle. Generally, the tail of the chain saw file is round, and there are also pointed and square ones. You can buy the corresponding file handle. In order to extend the service life of the file, the following rules must be observed:

1. Do not use a new file to file hard metal;

2. Do not use a file to file hardened materials;

3. Forgings with hard skin or sticky sand For parts and castings, they must be ground off on a grinding machine before they can be filed with a semi-sharp file;

4. Use one side of a new file first, and when that side is blunt, use the other side;

5. When filing, always use a wire brush to remove the chips on the file teeth;

6. Files cannot be overlapped or stacked with other tools;

7. When using a file, the speed should not be too fast, otherwise it will easily wear out prematurely;

8. Avoid getting the file wet, oily or other dirt;

9. Fine files are not allowed to file soft metals;

10. Do not use too much force when using the file to avoid breaking.

Replacement Of The Chain Saw Sprocket

The chain saw sprocket is generally installed behind the clutch cup, so the clutch on the clutch cup must be removed before replacing the sprocket. The clutch thread of the chain saw is a reverse thread nut, and the general clutch There will be a clockwise OFF direction arrow printed on it, which means that clockwise rotation means loosening and disassembly, and counterclockwise rotation means locking. Generally, the clutch and crankshaft of the chain saw will be tightened with screw glue when they are assembled and shipped from the factory, so special tools are required for normal disassembly: electric or pneumatic wrench and 24 or 26 diameter three-tooth socket. The 24 or 26 diameter three-tooth socket can be made by yourself. You can cut off the three separated edges of the 24 or 26 socket, so that the clutch can be stuck. If the above tools are not used, you can also use tools that are easier to knock and bear force, such as a T-bar socket plus a hammer, and knock clockwise along the OFF arrow on the clutch. This method is more difficult for novices to disassemble, and requires some patience and strength skills. It is best to use a hot air gun to heat a screw part before knocking. After replacing the sprocket, for the safety of tool use, please remember to lock the clutch installation.

The above is the use of chain saw files and the replacement of chain saw sprockets. I hope it can help you. If you have any questions, please contact us.
