Sharpening a chainsaw chain at home

How to sharpen the chain of a chainsaw quickly and carefully without dismantling it

The chain of a chainsaw can be sharpened in a workshop (the price of the service from 250 ) or with your own hands in the presence of special devices. But what to do when the tool is blunt at the sawmill or in places where there are no workshops or special devices for sharpening? In this case, you can use diamond-powdered nozzles and get your chainsaw back up and running quickly and without too many problems yourself, knowing a few simple rules for sharpening.

Using diamond tipped tips for sharpening chainsaw chain links is not only appealing because of its simplicity and efficiency. The cutter bits also ensure a gentle sharpening process by removing a minimum thickness of metal from the cutting tooth compared to an emery or angle grinder. This allows more re-sharpening, which greatly increases the life of the chain before it is completely worn out.

If you keep on working with a dull chain it will require more physical effort, cutting performance will suffer, the engine will overload, fuel consumption will increase and the life span of the chain saw will sooner or later run out. That’s why you should not wait too long to sharpen the chain.

It is possible to sharpen cutting teeth with diamond-coated attachments without removing the saw chain from the guide bar, which will not only reduce sharpening time in logging conditions, but also provide certain conveniences. But be sure to put the chain on the brake.

For convenience we sharpen the left tooth first and then the right one, or vice versa. Place the bur between cutting edge of the tooth and kerf at an angle of 25-30 degrees in the horizontal plane and perpendicular to the chain in the vertical plane.

When sharpening, the bur should be slightly elevated above the tooth and rotate towards it. This way is good that it doesn’t burn out the tooth stinger and doesn’t weaken it, like it happens during grinding with an emery or angle grinder with their high revolutions.

By the way, instead of an electric screwdriver you can use a drill or grinder with speed up to 2000 rpm. But you have to be very careful, because the metal removal is intensive.

Since the height of the tooth decreases with each sharpening of the chain, it is necessary to sharpen the depth limiter after 2-3 sharpenings with a flat file or a diamond-powdered nozzle.

When to sharpen a chainsaw chain?

While working with a chainsaw, even the best quality tool, the chain loses its initial sharpness over time and needs to be sharpened. What are the signs to realize that the chain of an electric chainsaw or a chain saw has blunted and it is time to sharpen it?

The following are the main signs that it is time to sharpen the chain:

  • During operation, the saw loses stability, pulls out of your hands and vibrates strongly;
  • chain saw or electric saw produces only small chips and does not produce large chips;
  • The saw’s part binds in the material, sawing cannot be done qualitatively and quickly;
  • deepening of the chainsaw into the wood does not happen by itself, in order to make a longitudinal cut, the tool has to be “sunk” by hands into the material, applying force and pressing the blade;
  • the saw produces a curved cut during sawing;
  • The chainsaw heats up quickly and badly;
  • the chain wears down much faster;
  • fuel consumption increases.

If you have noticed several of these signs on your home tool, it is time to sharpen the chain.

The original chainsaw chain can be sharpened several times, it will retain all operating properties. sharpness of cut, quality of cut, speed of rotation on the bar.

A few important tips to help keep the chain on your chainsaw from sharpening for longer:

  • Do not use a new chain with an old sprocket and vice versa;
  • If you have already sharpened two chains while using your chain saw, replace the sprocket with a new one;
  • The chain should be run-in before normal use with a normal load (run-in immediately before sawing, 1 minute at low RPM and then 1 minute at medium RPM);
  • After the new chain has cooled down, you should check the tensioning of the chain;
  • Always use chain lubricant for chainsaws, quality oil;
  • Maintain the normal tensioned position of the links, because during operation the chainsaw is often tilted in different directions, which increases the likelihood of the chain slipping off the bar;
  • check the position and orientation of the kerf limiter, after the 3rd or 4th sharpening check the limiter parameters.

Preparing the tool

First remove the shank, i.e. the part of the file that fits into the handle. You can do it with an emery or an angle grinder, whatever is more convenient for you. Then put the file in the chuck of the drill or screwdriver and clamp it.

Then we make a sleeve from wood, plastic or any other material, which fits tightly on the free end of the file. The inner ring of our bearing should fit tightly on the outer surface of the sleeve.

This is done in order to be able to hold the tool with two hands during work. one by the handle of the drill, the second. by the outer cage of the bearing.

How to correctly sharpen a chainsaw chain on a chain sharpening machine

It is much faster and more precise to sharpen the chain on a machine than by hand. There are many different electric chain sharpeners on sale. Household machines are compact, working from 220 V. Abrasive wheels are easy to change and can be easily adjusted for different chain parameters: tooth pitch, top edge thickness, sharpening angle. All sharpened cutting edges are identical. Process is fast.

Electric chain sharpening machine for chainsaws

The main part of the machine is the electric motor on the shaft of which the sharpening disc is installed. There are controls on the handle. There is a clamping base for securing the machine to the chain. A spring clip provides adjustment of pressing force on the sharpened element. Differentiated clamping provides self-alignment of the product in the machine. There is a hinged safety guard for safe operation.

How to sharpen a chainsaw chain

Chainsaw chain sharpening is a procedure regularly encountered by gardeners and professional woodcutters. In this article, a master plumber will tell you how to repair damaged saw teeth and get it back in working order quickly.

To understand how to properly sharpen a chain, it is necessary to understand the basic principles of its construction and operation. You can’t just sharpen a chain by eye, you need to know the basic characteristics of the chain and its components.

A chainsaw chain is made up of three kinds of links made from high-alloyed steel:

  • Cutting. the basic elements of the chain. A distinction is made between right-handed and left-handed, which are arranged alternately, their cutting edges are located above the plane of the bar. The design of the teeth includes cut depth limiters.
  • Drives (shanks). serve to transmit torque from the gasoline motor to the chain through the drive sprocket. This feature extends sprocket life and gives the chain a more stable hold on the bar.
  • connecting links. connecting the chain shafts and cutters.

One of the key elements of a chain is the cutting tooth that plunges into the wood and removes shavings. The tooth depth limiter determines the thickness of the wood chip and limits the depth of penetration into the wood.

Recommended settings relative to the limiter are 0.025″ (0.65 mm) or 0.030″ (0.75 mm), depending on the type of chain.

The long life of any chainsaw depends on proper care and use, including that of the chainsaw. The good performance of the latter affects the unit’s performance and productivity parameters. Failure to sharpen on time can cause some problems with the saw itself. The most common ones are:

  • Crooked cuts;
  • Heavy loads on the saw, resulting in increased wear on the parts of the device and therefore a reduction in the service life of the entire device;
  • Increased fuel consumption.

If the saw produces fine, dusty chips and the saw itself sinks into the cut with great force, then the target is dull.

There are other signs of a dull chain:

  • The speed of the tool has decreased;
  • Uneven and sharp sawdust is produced;
  • You have to use a lot of force to cut through the wood;
  • The chain is stretched or has become slack.

A chainsaw chain can quickly become blunt for the following reasons:

  • If you work with the saw too often;
  • When the operator presses hard on the saw while sawing;
  • If the chain is made of poor quality metal or if the steel has not been properly heat-treated;
  • If sawing raw or resinous wood frequently;
  • When sawing hardwood trees such as: oak, birch Karelian, cherry, acacia, elm, ash and others;
  • When the chain encounters an obstacle in the form of sand or stones;
  • If the chain is not properly sharpened or has insufficient tension when working.

The design of all chain saws is similar, so the chain removal procedure will be the same:

  • First put on oven gloves, cotton gloves, to avoid cut by the cutters.
  • Remove the protective boot from the chain saw and lay it on its side on a flat surface.
  • With a socket wrench of the right diameter, unscrew the fixing nuts that hold the housing and the bar, remove the upper cover of the housing.
  • Now push the guide bar all the way down to the chain sprocket thus loosening the chain and remove the working parts from the bolt fasteners.
  • Disconnect the chain from the bar.
