Any user will get frustrated when their chainsaw suddenly fails to cut straight on wood projects. There are a lot of pretty common causes for a chain to cut crooked, and it happens a lot.
At some point, forcing your saw to maintain a straight line becomes challenging, and we understand the dilemma. Our experts will break down all the possible solutions and reasons why your chainsaw cuts crooked.
Reasons Why a Chainsaw Cuts Crooked and How to Fix it
Reason #1: Uneven Sharpness
Manual sharpening can cause the chain curves to get dull. Right-handed people often tend to sharpen the left side more than the right side, causing uneven sharpness that leads to the cutter tooth taking a different-sized bite on the wood.
How to Fix Unevenly Sharpened Chains
For proper sharpening of the saw, it’s best to pay equal attention to both sides of the chain., including the basic component – the cutter tooth. Don’t focus on your dominant hand all the time; instead, work on the one side that you feel lacks attention until you get the perfect balance of sharpness on both sides.
Sharpening a Chainsaw That Cuts to the Right or Left
Here’s a simple guide on how to sharpen your chain to avoid crooked cutting.
- Use wrenches or pliers to pull off excess materials around the blade.
- On the end where the teeth meet, place a file on top.
- File evenly by pushing down on the tooth, firmly in a back and forth direction.
- Place the fine-grit sandpaper on top of the tooth to sharpen, and remove any burrs by filing until both sides are equally smooth.
Reason #2: Unequal Top Plate
Unequal length on the top plates is one of the most common reasons for uneven bites, prompting the chainsaw to curve and form an angle on the heavier side.
How to Fix an Uneven Top Plate
To avoid your saw from making crooked cuts, the weight of the plate should always be evenly distributed, which means a 180 degree is the ideal angle.
If you notice that the other plate is smaller, then sharpen the longer side with your dominant hand. This makes it easier to get a cut straight and get exact angle proportions to avoid distortion on the plates.
Reason #3: Bent Bar
An irregularly shaped or dented bar is one of the most common reasons for the chain to curve when cutting. Bent chainsaw bars can cause a chain to cut crooked.
How to Fix a Bent Bar
Lay your bar on a flat surface. Fixing a bent bar isn’t that difficult and can be done without technicalities. Just use a hammer to straighten out the peaked side of the bar and adjust the strength depending on the bar’s condition.
Reason #4: Uneven Cutting Teeth
The most common cause of crooked cuts is uneven cutting teeth, often the results of tear and wear. It’s common for the chain teeth to get sharper on the other side due to uneven sharpening.
Dragging your chainsaws can also cause the teeth to bend and pull in one direction. When the teeth are of unequal sizes, this can lead to cuts favoring the side with the biggest bites.
How to Fix Uneven Cutting Teeth
To prevent dulling the chain teeth easily, eliminate any hard objects such as nails and rock. These are often the culprit to your cutter teeth getting uneven.
In most cases, getting help from a professional is ideal for sharpening the chainsaw teeth evenly, but if you insist on doing it, use a grinder when sharpening instead.
Reason #5: Improper Chain Tension
Another likely reason why your chainsaw is not cutting straight or is causing crooked cutting is improper or loose tension on the chains. Not getting the right amount of tension on your saw can lead to crooked cuts and even a bigger problem on your chain.
A tightened chain will prevent the saw from cutting straight and moving freely around the guide bar.
How to Fix Improper Chain Tension
Know the proper tension you want for your chainsaw to work in the proper direction. When you pull the chain, you should be able to see ¾ of the drive links, and it should spring right away., To fix chain tension, consider the temperature, as it’s another common reason you end up doing it incorrectly.
Hold your guide bar when you adjust the nuts of your chainsaw until you get a fair tension. Always wear protective gear when adjusting loose tension to avoid cuts on your finger.
Understanding Your Chainsaw
Getting a chainsaw for your woodworking needs is just the first step, and it’s not a guarantee fewer headaches while doing your projects. Not reading the manual and not understanding how to use it properly can cause more anxiety for typical woodworkers.
We recommend understanding how your chainsaw works accordingly to model and type to avoid the common culprits of chainsaw problems.
Choosing and Buying a Chainsaw + Proper Maintenance
A chainsaw purchase is one of the best investments; hence, buying the right one for your specific needs. Consider the power and usage if you’re using the chainsaw for DIY. Often a battery-powered saw is ideal.
However, professionals should opt for more high-end versions, usually gas-operated. Whichever it is that you have, keep in mind that maintenance includes both the motor and chain .
The Most Common Issues With Chainsaws + How to Fix Them
Issue #1: Overheating
Overheating is a common reason why engines get damaged causing your chainsaw to stop running. To secure smooth usage of your chainsaw, maintain regular cleaning, especially if you’re using it during the summer when chainsaws can easily overheat. Always clean the exhaust, which can get overflooded with broken wood particles and sawdust.
Issue #2: Flooded Engine
Flooded engines always happen even in top brands like Poulan. It is brought about by undrained gas on your machine. Starting the chainsaw without oil can also pose risks for flooded engines. It can be tedious to re-start the machine, but after a couple of pulls on the starter, it should work sharp again.
Issue #3: Turnover
You’re probably trying to figure out what causes turnover issues on your Husqvarna saw. Our experts found out that often, improper lubrication is the perpetrator.
The turnover issue is one of the chainsaw problems that surprise users. Abusing the engine or leaving it stagnant can cause problems, so you have to follow proper maintenance to relieve you from possible headaches.
Why does my chainsaw keep jamming?
Chainsaws are purposeful in cutting wood. However, you need to consider the tree’s weight and opt for manageable size logs. Often the blades can wear when you force them into cutting heavyweight woods. Chainsaws will jam too if you cut wet or softwood trees, as it’s primarily designed for cutting hardwoods only.
Why does my chainsaw produce smoke?
Users who aren’t used to the sight of smokes when cutting wood with their chainsaws often get intimidated once this rare occurrence happens. Cases like these happen when you use improper oil, causing the chain to malfunction.
Abusing the machine and running it longer than the desired period can also lead to smoking. Not adding enough oil is another culprit to unusual smokes.
How long should a sharp chainsaw chain last?
Keeping your chainsaw chain sharp requires proper maintenance. However, this doesn’t signify a lifetime guarantee on chainsaw chains.
You’ll eventually need to replace your chains to maintain satisfactory performance. At most, a chainsaw chain’s sharpness can last for five years for regular users, but casual woodworkers can expect a longer lifespan.
When it comes time to buy a new chain for your chainsaw, make sure you are buying the right one by consulting this chainsaw chain identification chart.
