How To Use an Electric Chainsaw Sharpener

The high power motor of an electric chainsaw cannot produce good quality cuts if it has a dull blade. Whatever type or quality of blade used, excessive or continuous use of your chainsaw wears out the blade so it is crucial to sharpen it regularly. 

Neglecting this essential aspect of maintenance of your electric chainsaw will not only yield poor quality cuts but will also require the user to exert more effort, causing unnecessary strain. This is potentially precarious as most chainsaw accidents occur when the user is fatigued, which lessens his control over the machine.

Visual assessment is not usually sufficient to determine the sharpness of the blade. Most blades, especially those that are of high-quality, will maintain looking sharp even if the blade is already blunt. Watch out for signs such as crooked, uneven cuts and production of sawdust that indicate that the blade needs sharpening.

Determine the type and specifications of the blade. Each blade has specific features in terms of the size, thickness, tooth angle and swivel angle. You can normally find the relevant information on the label of the chainsaw and the user's manual.

Find a durable surface and wide space. Make sure that you work in a space where you can easily handle and move the blade around as you sharpen it. Use a mount that is stable and durable to prevent slipping and other accidents.

Install the sharpening stone the place the blade in the machine. Use the specifications of your blade to obtain the correct size of the sharpening. Each blade needs a particular size of stone and using the wrong size can damage the blade. Consult the manufacturer's instruction if there are specific guidelines as some stones can only function in a certain orientation.

Adjust the machine according to the blade's specification. First, modify the swivel angle to guide the movement of the grinding head. Regularly, it is adjusted to sixty degrees but it can be adjusted anywhere between zero to eighty degrees. Secondly, set the blade angle to determine the arc of the teeth, which controls the grip of the blade as it slices the wood.

The control for this is normally found below the blade holder. The setting can be anywhere between positive ten to negative 10 degrees. Next, adjust the blade tooth backstop by moving the grinding wheel closer or farther from the blade.

You can opt to use the spring-loaded backstop to make sure all the teeth touches the dame point beneath the grinding wheel. Lastly, adjust the depth stop to determine the amount of metal to be shaved from the blade. Adjust the depth stop so that the grinding wheel is only slightly touching the inner arc of the tooth.

Start the grinder. Turn on the grinder and start sharpening by slightly laying the wheel to the tooth. Check for a smooth, shiny edge at the curve of the tooth. If you see this, move on to the next tooth at the same side of the blade until all the teeth are sharpened

Move on to the next side. Re-adjust blade angle before continuing. If you set the angle in the positive 10 degrees in sharpening the first side, set the angle to the negative 10 degrees this time around. Once you have done this, proceed onto the sharpening of the tooth as instructed above.

When you sharpen the blade using an electric sharpener, make sure that you are appropriately dressed with the necessary safety equipment. Safety should be your utmost concern in doing this task. Keep your focus and be certain of the process to prevent any major damage to the machine and any injury to yourself.
