How To Sharpen Chainsaw

Is it worth sharpening chain saw blades?

If your chainsaw chain becomes dull after a long lifespan, it will struggle to cut through the wood at the efficiency it once had. This is why, where possible, you should be looking to keep the will be chain sharp, as sharpening a better course of action than sourcing a replacement.

How many times should a chainsaw chain be sharpened?

A chainsaw chain can be sharpened up to 10 times, sometimes more, before the entire chain needs replacing. It’s mostly dependent on two things; the amount of wear your chain incurs and the amount of metal removed every time you sharpen. Different materials can have a harder impact on the chainsaw chain.

Why does my chainsaw chain dull so quickly?

Reasons why a chainsaw becomes dull – 1. Contact With The Ground With a single contact with the ground while running, a chainsaw can become very dull. This is because the ground contains sand and dust which is abrasive and contains a lot of tiny rocks.

To avoid such occurrences, avoid cutting wood placed on the ground. If you happen to cut huge logs of wood, roll the log when needed to prevent the chainsaw from hitting the ground.2. Cutting Dirty Trees When it comes to felling or bucking, most of these trees have their barks covered in soil and dirt.

This dirt and soil can cause your chainsaw to become dull. Over years, tree barks tend to accumulate lots of dirt and soil carried by the wind. Luckily, there is a way to prevent your chainsaw from getting dull by the soil and dirt on tree barks. Removing the barks from a tree before cutting is a great way to prevent chainsaws from getting dull,

  • You do not have to completely take off the barks.
  • Using an axe, take out the bark right at the spot you want to cut.3.
  • Strong or metal objects in the wood This may appear strange to you, but the wood you are cutting may have an object inside.
  • It can be a piece of metal or a nail.
  • You’re wondering how an object like that can end up in the wood or tree you’re trying to cut.

Well, objects like nails are often nailed into trees or woods to put up signposts, while building a birdhouse or a treehouse for kids. Irrespective of how the object gets into the wood or tree in the first place, it can still make your chainsaw instantly become dull. One effective way to take care of such situations is to use a plier to pull out the nail. However, the most logical solution is to either cut from another position or completely discard the wood.

Is it hard to sharpen a chainsaw?

Download Article Filing and leveling the cutters and rakers of a chainsaw blade Download Article A chainsaw makes quick work of trees and other lumber. Over time, however, you may notice that you struggle to cut with the same ease as before, which indicates a dulled blade in need of sharpening. Luckily, sharpening your chainsaw blade is a simple enough task, and it’ll only be an hour or so until your chainsaw is back in operating condition.

  • Place the bar of the chainsaw in a tabletop vice, and tighten the tension of the chain so that it doesn’t move around as you work.
  • Use a file guide to position a round file at an angle to the cutter, or align the file with the guidelines on the tooth.
  • File toward the point of the cutter 3-10 times, or until the cutter is silver, indicating it’s been adequately sharpened.
  • Use a depth gauge to measure the height of each raker, and file down any that stick up past the top of the gauge.
  1. 1 Clamp the bar of the chainsaw to your work surface. Use a tabletop clamp or a vise to hold the chainsaw in place on your work surface. This will prevent the saw from shifting as you sharpen it, and result in a much more consistent and easy sharpening process.
    • Securing the chainsaw upside down on your work surface often makes for easier access to the chain. There’s no one right way, so find the method that works best for you.

    Note: If you need to sharpen a chainsaw but don’t have a vise or clamp, you can go without it. Be careful to keep the chainsaw steady as you file it if you can’t secure it in place, and wear sturdy gloves as your work.

  2. 2 Tighten the tension-adjusting screw to tighten the chain. Find the tension adjusting screw on your chainsaw—usually on the side of the saw and perpendicular to the direction of the chain. Use a screwdriver to tighten the chain by tightening this screw. Make sure the chain is tight, but is still able to move around the saw with a little effort. This stops the chain from moving as you sharpen it. Tip: The adjustment screw will be in different places on different chainsaws. Consult your owner’s manual for the chainsaw if you can’t find it.

  3. 3 Mark your first tooth with a permanent marker. Select a tooth to sharpen first (most commonly the shortest or smallest tooth) and mark it with a bright permanent marker to easily keep track of where you started and prevent you from sharpening the same section twice. As you use the chainsaw, this mark will disappear.
    • If you don’t want to mark your chainsaw, look for a unique link in the chain. It might have no teeth, or already be a different color.
    • Alternatively, mark the tooth with a bit of painter’s tape after you’ve filed it.
  4. 4 Select a round file the same diameter as the chainsaw’s teeth. Different chainsaws have different sized teeth, and therefore require different sized files to sharpen. Find the size of your saw’s chain in the owner’s manual or online, or read the information occasionally printed on the bar of the chainsaw. Note: Typical sizes for the chain are 3 ⁄ 16 inch (4.8 mm), 5 ⁄ 32 inch (4.0 mm), and 7 ⁄ 32 inch (5.6 mm) in diameter.
  5. 5 Set your file in the notch on the front of the cutter. The cutter is the angled “tooth” with a flat top, which rips at the wood. Place the tip of the file just inside the notch on the tooth you have marked so that roughly 20% of the file’s diameter is above the top of the tooth.
    • The chain has two types of cutters facing alternate directions. Choose one direction of cutter to focus on first before moving onto the other type.
  6. 6 Position your file guide at the factory default angle of the cutter. Check your owner’s manual or look online to find the correct angle at which to file each cutter. Position the line on the file holder so that it lines up parallel to the rest of the chain as you file.
    • Some chainsaws also have lines etched into the top of each cutter to help guide your file at the appropriate angle. Line your file up so that it is parallel with this etching to set the proper angle.
    • The angle for filing is typically 25 or 30 degrees, but some may be flatter. Always check the angle needed for your saw before beginning.

  1. 1 Slide the file across the face of the cutter. Hold the file so that it remains level and flat over the top of the chain. In one smooth motion, push the file along the cutter. You don’t need to apply a lot of pressure, only enough so that you feel the file grinding against the cutter. Lift the file out of the cutter and reset it to the same place and at the same angle as it was previously. Note: Never pull the file backward through the cutter, as this will damage both your file and the cutter itself.
  2. 2 File the cutter 3 to 10 times until it is sharp. Repeat the exact same motion of running the file through the cutter until the cutter is a shiny, silver color and appears sharp. To ensure consistency across the sharpness of each cutter, count how many times you file the first cutter and file each subsequent cutter the same number of times.
    • If you’re unsure whether or not the cutter is sharp, feel for a slight burr along the top of the cutter. If this is present, the cutter is adequately sharpened. Run the file over the burr once to knock it away.
    • If you notice metal shavings getting caught in the file, simply tap the file on a solid surface to clear it and continue sharpening.
  3. 3 Sharpen every second tooth from the starting point. Once you have fully sharpened your starting tooth, rotate the chain to bring a new tooth closer. The cutters on a chainsaw alternate directions, so sharpen every other cutter using the same motion, at the same angle, the same number of times until it is sharp. Repeat until you get back to the starting mark you made. These two cutters are referred to as right and left cutters. By alternating them, the chainsaw is more easily able to cut in a straight line without leaning to one side or another. If you file one type of cutter more than another, you risk throwing the balance of the chainsaw off. Make sure you stay consistent across all cutters.
  4. 4 Rotate the chainsaw 180 degrees. Loosen your vise or clamp and rotate the chainsaw 180 degrees, then clamp it again. This grants access to the alternate cutters that you skipped sharpening in the first loop around the chain and means you don’t need to change your stance or method. Tip: If you can’t easily adjust the position in which the chainsaw is clamped, step around the chainsaw or adjust the position of your file so that it faces the other direction. Regardless, make sure you remain consistent.
  5. 5 Use the same motion to sharpen every other tooth. File your way around the chain again, sharpening each tooth that has not yet been sharpened. Make sure to use the same amount of pressure and run the file through the same amount of times in order to keep each cutter consistent and level.

  1. 1 Place a depth gauge over the chain and check the rakers. A depth gauge is a tool used to ensure that the rakers are at the proper height. Set the depth gauge over the chain near your starting point so that the “wings” face downward, and push it forward until it catches against a raker. This indicates the raker needs to be filed down. The rakers are the bumps along the chain in between each cutter. They function to keep the depth of the cut consistent as the chain spins around the saw, so making sure each is level is very important.
  2. 2 Use a flat file to level the raker to the gauge. Holding the depth gauge in place, run a flat file over the top of the raker until it is level with the depth gauge. While the depth gauge will protect other teeth from being filed, there is nothing to stop the gauge itself from being filed down.
    • To entirely avoid filing the gauge, slide it back while you file over the raker. Check the height of the raker consistently as you file until it lines up with the top of the depth gauge.
    • Once you have filed the raker down, it might have a square top. Use the flat file to very slightly smooth off the edges without filing down the height of the raker any further.
    • Unlike the round file, the flat file doesn’t need to be any specific size.
  3. 3 File every raker down to the top of the depth gauge. Continue the same process of checking rakers with a depth gauge and filing them down all the way around the rest of the chain. Unlike the cutters, you don’t need to worry about filing the same raker twice as you are filing the rakers down. Tip: As with the round file, if you notice any metal shavings getting caught up in the flat file, tap it on a surface once or twice to loosen them before continuing to file.
  4. 4 Loosen the chain and release the chainsaw. Use the adjustment screws to loosen the chain back to a usable tension. Loosen the clamp or vise holding the chainsaw in place and take the chainsaw out. Your chainsaw is now be sharpened evenly and ready to use.
    • A chain at a usable tension has very little visible slack as you hold it. When you lift the chain up, it should have around 1 ⁄ 8 inch (3.2 mm) of give and snap back when released.
  5. 5 Refill the bar oil reservoir in your chainsaw, and clean the saw. Turn your chainsaw on its side to reveal the cap for the oil reservoir. Unscrew the cap and use a funnel to pour in bar and chain oil, Replace the cap and secure it tightly. After, clean your chainsaw to remove any filing debris before you operate it,
    • As a rule of thumb, sharpen your chainsaw every time you refill the oil—and refill the oil every time you refill the gas tank!

    Tip: Vegetable oil, such as canola oil, can be used in place of bar and chain oil. This is biodegradable and therefore more environmentally friendly.

  • Check periodically for wear on the drive links, the blade groove, and sprocket. Chains can break and cause serious injury or death when operated with worn or damaged parts.
  • It may not be necessary to use brand-name chains, depending on your saw. Store/distributor brands are made by many of those same companies, using the same design specifications. Just be sure to use a chain with the correct pitch, gauge, and profile any time they are specified for a given task.
  • It is recommended that after a chain has been hand-sharpened 5 times, it be ground by a chainsaw shop to correct any variations in tooth pitch that occurred during filing.

  • Never trigger the saw while sharpening the chain. Advance the chain only by hand during the sharpening process. For safety’s sake, disconnect the spark plug wire before working on the chain.
  • Manufacturers recommend checking and readjusting chains often, especially when first using a new chain (the break-in period).
  • New or sharpened chains always deserve careful treatment and use. It is recommended to fully saturate (soak) a new or reconditioned chain in the recommended oil.
  • For best results, adjust and file chains when they are cool, as all chains tend to loosen (expand) in the heat of operation, even after the break-in period.
  • Do not force the chainsaw file or use too much pressure, which could damage both the file and the cutter.
  • Wear gloves and safety glasses/goggles during the sharpening process. You are dealing with extremely sharp edges, and without gloves, you could easily cut yourself.
  • Not all chain bars are standard in how they are attached or adjusted. Always check your owner’s manual when working on your own chainsaw.

Advertisement Article Summary X To sharpen a dull chainsaw, clamp the bar of the chainsaw to your work station and tighten the chain using the tension adjusting screw to make sure it won’t move. Then, use a permanent marker to draw a line on the link where you’re going to start filing, and get a specialty chainsaw file that’s the same diameter as the chainsaw teeth.

  • To file, hold the file between the teeth at a 30 degree angle, and slide it across the face of the cutter 3-10 times until it is sharp.
  • Sharpen every other tooth until you return to the starting link.

Does the chainsaw teeth sharpener really work?

Do Chainsaw Sharpeners Really Work? – Blade sharpeners work very well – but only if you buy a good quality product. They are quick and easy to use, saving you the expense of having to buy a new chainsaw chain when yours gets dull, and it ensures you get a clean cut every time.

How long should a chainsaw stay sharp?

Q: How long should a chainsaw blade stay sharp? – The duration of time between sharpenings really depends on the amount that the saw is used. A chainsaw may only need to be sharpened once a year if it is rarely used, but a tool that is frequently used will need to be sharpened regularly to ensure that the blade doesn’t get too dull.

Which blade never needs sharpening?

Serrated Knives – The most common type of knife sold as one that won’t need sharpening has a serrated edge, like a saw blade. The jagged teeth of these knives will cut even when they are dull, which makes them a good choice for cooks who don’t like the constant maintenance required by some other types of knives.

Can you put too much chain oil in a chainsaw?

Can You Put Too Much Bar Oil In a Chainsaw? – Technically speaking, you can’t put too much bar oil into the fuel tank of your chainsaw (unless it’s overflowing, which would not be good). What’s important is that too much oil is not being used by the chainsaw on the bar and chain.

How do pros sharpen a chainsaw?

For professional-quality chain sharpening that doesn’t leave your arm limp with exhaustion, you can use a heavy-duty chain grinder. A chainsaw grinder features a clamp that holds the chain in place while a grinding wheel is lowered down to smooth the teeth to a razor-sharp finish.

Why does my chainsaw cut to the right after sharpening?

Why does your chainsaw cut crooked ? You are most likely to notice this when sawing larger pieces of wood, and the causes can be varied, Let’s start with technique : you should start and finish the cut in a straight line, without pushing the chainsaw sideways.

The length, i.e. wear of the left and right chain teeth is uneven: this can happen when one of the sides hits a stone or piece of metal. The teeth aren’t sharpened correctly along one side, perhaps because they were improperly filed, without maintaining the same sharpening angle. The guide bar rails are unevenly worn and therefore asymmetrical, insofar as one is lower or thinner than the other. The guide bar track is too wide for the chain, either due to wear or because the bar is paired with the wrong chain.

It is completely normal for the guide bar rails on a chainsaw to wear out due to the constant rotation of the chain. However, if the chainsaw cuts to one side, then as we said, the problem is uneven wear. It may be due to the fact that the chain cuts at an angle, is badly sharpened, incorrectly tensioned, or not sufficiently lubricated, In addition to correct cutting technique, the secret to making sure your chainsaw cuts straight is good maintenance :

Carry out routine sharpening of the chain using a round file, for example: all the teeth should be sharpened and in the right way (with the same length and sharpening angle). You can find out more in our article on how and when to sharpen your chainsaw’s chain, Pay special attention to sharpening if you need to fix a specific problem, such as asymmetrical sharpening. Check and adjust the chain tension, Keep the guide bar and chain lubricated : here you can learn more about how the oil pump works and how to maintain it, Flip over the guide bar periodically, so as to even out the wear as much as possible. Grind the guide bar rails with a flat file or, if you prefer, take your chainsaw to the technicians at your nearest Oleo-Mac service centre, If necessary, change the chain, guide bar and sprocket : we recommend changing the sprocket with every second chain replacement and the guide bar with every fourth chain replacement.

Maintenance is not solely about the guide bar and chain: here are all the chainsaw maintenance jobs you need in order to avoid unpleasant situations, such as a chainsaw that stops suddenly after starting (possibility due to the carburettor flooding with fuel; by the way, here’s how to prepare fuel mixture ).

Does cutting wet wood dull a chainsaw?

Does Cutting Wet Wood Dull a Chainsaw? – Using your chainsaw to cut through wet wood will not dull the chain any faster than using it for other types of wood. When you think about it, your chainsaw chain is already wet. True, it is not wet with water. But it is wet with a lubricating mineral oil.

How do you know if a chainsaw is blunt?

Uneven cut – A chainsaw should leave a clean line in its cut, but this isn’t the case when the blade is dull. Instead of one straight line, a dull chainsaw blade leaves a chewed, uneven one. This is because the cut is not smooth, and the blade is chewing on the wood rather than gliding through it effortlessly.

Does hitting dirt dull a chainsaw?

Don’t Cut Into Dirt – Nobody plans to run their chain saw into dirt. But when you cut close to the ground, you’re just begging for a quick dip into dirt, rocks and crud. All it takes is a second in the dirt to dull the cutters. In addition to dulling the cutters, dirt also wears out the chain links faster, causing the chain to stretch. cagi/Shutterstock

Do you push or pull file to sharpen chainsaw?

How to Sharpen a Chainsaw What you need:

Round file – This should be sharp, match the size of your chain, and fit into the filing guide. The most common sizes are 3/16, 5/32, or 7/32 of an inch in diameter. If you are unsure, check your owner’s manual. It is best to replace your round file after every 5 sharpenings. To ensure sharpness after use, coat them in lightweight machine oil and keep them in a cloth so they don’t hit other objects and dull. Depth-gauge guide and flat – The depth gauges are rounded parts that are in front of every cutter that goes upward and almost seem to reach the top of the cutter edge. You want your raker to be about 1/10 of an inch lower than the cutter. If it is closer than that, then you need to file it down with a flat mill bastard file. Vise – This will hold the blade of the saw in place on a solid surface.

Let’s sharpen things up! First of all, make sure you know the size of your chain’s saw. Next, you should clean your chain. You can do this by using a brush and some sort of commercial degreasing detergent to get rid of any objects or oil. Once you have your chain clean, inspect it for any run-down or busted teeth and links.

Look at the flat surface at the top of the cutting teeth. Is it at least ¼ of an inch in length? If not, your chain could break during use, so you should just be safe and get a new chain. After inspection, secure the blade of your saw in a vise on top of a solid surface as shown above. This security will make filing easier.

Then you want to have a starting point so you aren’t filing your chain all day long with no end in sight. Typically the shortest cutter, or leading cutter, on the chain is the starting point. If they look all the same then you can just pick any cutter, just mark it with something like a permanent marker.

  • The bottom line is you want all of the cutters to be about the same length.
  • This way your chainsaw will cut into things smoothly and easily.
  • Now the filing can begin! Put your round file into the notch on the front part of the cutter.
  • The round curve file should fit this angled tooth.
  • About 20% of the file should be above the top of this tooth, which you can see below.

Then check the angle you should file on your owner’s manual. It is usually 25 or 30 degrees. You can push the file either way though most prefer going towards the cutter’s point. Twisting while filing will get rid of the small metal bits and give you a smoother cutting surface.

This is the cutter and where you want to sharpen it. As you move from tooth to tooth, keep the one you are filing on top of the blade. Once you have filed all of the teeth, and they all look of similar height, it is time to move onto the rakers. Now it is time to check the depth gauge which are the hook-shaped links in between the cutters.

If they are not lower than the cutters by a tenth of an inch, they should be filed with the flat tool listed above. The last step is to check the chain’s tension and oil it, then you are good to go.
