How to sharpen a chainsaw
The power on the saw is located on the blade or chain. If the blade does not work properly, such as getting a blunt, then the chainsaw can be expressed has been paralyzed in its work performance. Usually to avoid mistakes in sharpening the blade on the chainsaw is to bring it to an expert or at stores where you bought earlier. Because, in general, a store that sells heavy equipment also provide spare parts.
You can know that you’re having a blunt chainsaw when you feel heavier than usual in doing a trimming or cutting, the cut when the object is not much different from the usual or even the same as usual. There are depth gauges located at the front of each tooth which regulate how far the chain is cutting into the wood. When the chain is sharp the teeth will cut as far as the gauge will allow. However this mechanism will not work when the blade is blunt and you find yourself having to press the machine deeper to create the cut. It means, you are required to rest and sharpen your chainsaw blade.
You can also know if your blade is blunt by the “residue” the cuts you are making are producing. A fully sharpened chain will produce large square type shaped chips, while in comparison; blunt chains create small chips that resemble sawdust.
There are two options for you to sharpen the blade. Take the chain to a saw sharpening company or conversely you can sharpen the chainsaw yourself.
But we can not continue to rely on the company services to sharpen the blade. There are times when we should be able to sharpen the blade by ourselves. The advantage is, other than you have new knowledge, you also can save repair costs. The needed things are:
- A pair of protective gloves – to protect the owner from the blade
- A chainsaw file gauge – to checks three things: the angles on each tooth; the tooth cutter length and the depth gauge setting.
- A round chainsaw file the same gauge as the chain on the saw – to get the correct sharpening of the chain
- A flat file – to attain the correct height of the depth gauge on the teeth
- A stiff brush – to clean the chain before sharpening
- A can of resin solvent – when applied to the chain this will clean and lubricate at the same time
After ensure your safety, this task will require you cover three areas: filing the top plate to the correct angle; filing the side plate to the correct angle; the depth gauge needs to be filed to the correct “bite”. You will be sharpening what is known as the “working” corner. This is the top area of each chain. By placing the chainsaw file gauge over the tooth you will see the marked angle the tooth needs to be sharpened at. Now place the round file against the tooth and align it with the markings on the gauge. As you push the file against the tooth, be sure to keep it aligned to the alignment mark. On the back stroke release the pressure before making another stroke.
You need to continue filing the chain until any tiny nicks or damages in the metal are removed. You will know your job is done when the corner of the cutting blades on the teeth are clean and have a thin chrome edge. Always work on the teeth on one side before changing the angle to work on the other side of the chain. And, it’s done.
