Use the 770S™ chain saw chain grinding fixture to make your chain saw as sharp as new, making your work more time-saving and labor-saving!

It is as easy to use as a pencil sharpener, just set the clamp to the rod, position the pawl on the tooth, insert the burr into the guide sleeve, and turn the handle.

Every time you grind a tooth, you only need to pull the chain. The precise sharpening can ensure that every tooth is repaired!

HOW IT WORKS ?

Use an auxiliary wrench to install the grinding head, and then install the small grinding head (4"-6") or the large grinding head (8"-22") as needed.

Put the installed grinding head into the cutting teeth in the corresponding direction.

Keep Alignment After Inserting the Grinding Head.

Tighten the Rear thumb screws until the pawl pushes against the chains tooth. The tool should rock on the carbide. Find balance point where neither end of tool touches chain. Lock this position by tightening the 2 outer side set screws.

After the first few steps are completed, you can start working.

After use, you can use a steel brush to clean up the residual garbage.

The chain saw sharpening jig is made of rust-proof stainless steel alloy material, which is durable and very strong. Each time you sharpen the teeth, just pull the chain, the precise sharpening can ensure that every tooth is repaired, and it only takes 3-5 seconds to clean the dull chain again
