How to sharpen your Chainsaw

Sharpening a chainsaw without a prior skill is risky to your life, and makes your machine vulnerable. You must comprehensively learn how to sharpen a chainsaw with a grinder using the guide below:

1. Identify your work space, and lock the bar of your chainsaw. Take your time and firm up all the tension adjusting screws to lock the chain, and prevent it from shifting.

Suppose you lack clamp to hold your chainsaw during grinding, you can improvise your own way instead. It may require some adjustment from you.

The way you hold a grinder, and your standing position matters a lot during sharpening. You may review the manufacturer manual where necessary.

2. Make sure to test your grinder before sharpening your chainsaw. The grinder is supposed to be tested at an isolated space to avoid damaging things around you.

This machine is composed of several moving parts, and you must ensure that they are all running. During this testing, discover any kind of malfunction that may hinder your sharpening.

Hold the angles of the machine appropriately with both hands, and set it on to see how it operates.

3. Before you sharpen your chain, you must start by investigating dented cutters. You will need to sharpen all cutters and level them to cut equally.

That is why grinders must be adjusted to match even a blunter cutter. Practically, the horizontal stop should lie against the rear edge of one cutter, making it keep a preset distance for the edges of the wheel.

4. Label the tooth from your starting point using a permanent ink. This will help you distinguish the sharpened tooth, and prevent you from sharpening the same tooth repeatedly.

The mark will be erased as you continue using the chainsaw. Also, a chainsaw can be built with a starting point indicator, but this might fade with time.

Check the edges of your chainsaw and you might find some unique spaces or marks with different colors.

5. Twist the threaded adjuster that regulates how deep the abrasive wheel chops. It should move deep enough to touch the bent side of the cutter, but not to cut the chainsaw body.

Try arranging some teeth before you start, and grind repetitively for some seconds until you achieve the defined grinding depth. Because the metal attached to the cutter is thin, it is advisable not to overheat it by prolonged sharpening.

6. As the operator​ you must confirm that the required speed limit of the grinder disk and dimension is properly set. Also, you must make sure that the angle of the grinding wheel is matched with tooth and the cutter of your grinder.

Do not force if the diameter of the grinding wheel is not matching the curves. Grinding machine is a safe tool when used in accordance with the basic guideline provided by the manufacturers.

However, if you handle them carelessly, there is a possibility that they will be subjected to regular failure, and you may as well endanger your life.

7. Grinding of chainsaw mostly involves shaping cutters to enable them to chop effectively. Therefore, you should regularly adjust the levels of the depth gauge.

These curvy extensions of metal are grounded besides each tooth. It controls the chops realized on a wood during sawing. After a few sharpening, the level of the cutter lessens considerably.

You need to adjust depth gauges to balance the level. Without this tactical sharpening, chains may not work appropriately.

8. Use cushion wheels layered with abrasives to get rid of unwanted metal splits, and smoothen the cutters. This is what grinding operators term as polishing.

It can also be used to remove a damaged tooth that cannot be repaired. On the other hand, you can use wire wheel mounted on the grinder to remove rust, paint, or dirt from the chainsaw.

Place the chainsaw on the wire wheel, and hold it firm as the wheel rotate until all the unwanted traces are cleared.

Don’t apply extra pressure against the surface of the wire wheel to avoid the dispersion of steel wires.​​​​​​​

Knowing how and when to sharpen your chain is a great deal of saving your time and money.

As a result, you must be careful to prevent fire breakout. Generally, a moment of divided attention may cause a great harm in your life as an operator.

When you are operating a handheld grinder, do not put it down when the disk is still rotating. Ensure your grinder is completely off before you place it on any surface.

Significantly, do not use mounting flanges when the surfaces which cling on the grinding wheel are warped, corroded, or full of dirt.

Powered grinders can be very hazardous if safety measures are not adhered to. The grinder can disperse wreckage's when sharpening materials so it is important to protect your eyes.

Do not forget to wear your gloves as the metal debris can piece your body. You may also find it relevant to wear ear protection and a dust mask.

The speed at which the disc rotates is an important factor for optimizing the performance of the tool. You can easily adjust the speed on your grinder to suit the sharpening requirement.

In most cases, starting with a minimum speed setting is recommended. You can adjust the speed once you are certain that the grinder is sharpening well. Also, you must ensure that the wheel is moving to avoid overheating.

Stay attentive to identify problems during sharpening. If your grinder is malfunctioned, consider reducing the speed to avoid further damage on the chainsaw.

When the wheel is rotating at a high speed, it can be difficult for you to control the sharpening on chainsaw teeth. Reducing speed will allow you to witness what is affecting your grinder, and finish your sharpening task effectively.

A faulty grinder may produce a loud noise and excessive vibration that may consume much of your energy when handling it. Reducing the speed will minimize this problem.

Your grinder is created with a side handler. For optimal safety and efficient operation, ensure you handle it properly. Use the handlers to set up maximum control when sharpening.
