The other way to tell if your bar is bent is to remove the bar from your chainsaw, then lay the bar on a flat surface to notice any bends. If you are not sure which bar is compatible for with your chainsaw, check out our step by step guide on how to buy the right chainsaw bar. Unless a chainsaw bar becomes bent or damaged, a chainsaw bar could outlast the chainsaw itself.
A crooked cut can be caused by uneven bar rails, uneven sized teeth on left and right side of chain, a slanted bar slot, uneven sharpness of left vs right teeth, a twisted bar, or a combination of any or all of the above. A slopppy fit of the chain in the bar groove by itself shouldn’t cause the cut to go to one side or the other. A bar groove too shallow will quickly ruin the drive links on the chain.
One of the less obvious aspects of chainsaw maintenance is proper inspection and management of the chainsaw bar. If you discover that your bar rails are worn down unevenly, it’s time to replace the bar. If your bar has lost its characteristic u-shape, it’s time to replace the bar.
If the bar you are using has significant heel wear, your saw probably has a tendency to “Throw” its chain. If you compare a worn bar to a new bar, you will notice the warn bar has a much narrower heel. To inspect a guide bar for damage, first remove it from the saw.

How long should a chainsaw bar last?
Re: how long does a bar last The next, a Granberg, lasted about 2 months. About that time Stihl started using them with the same results. A good bar can be filed a few times on both sides and the tip replaced when needed. They could last almost as long as the saw.
How often should I flip my chainsaw bar?
Some professional loggers would advocate that you should flip your chainsaw bar at the end of every use, particularly when you are cleaning up. Others suggest a more relaxed approach advising that you flip the chainsaw bar only when you are changing your chainsaw blade.
Can you burn up a chainsaw bar?
Fine. But why burn up a perfectly good chain saw just because you’re too impatient to wait for it to cool off? The heat from a hot engine vaporizes the fuel as you pour it into the tank. If the vapor ignites, you’ll be pouring gasoline right onto the, ah, fire.
Why does my chainsaw bar smoke?
This most commonly is a result of a dull chain and exerting to much pressure on the bar and chain trying to make the chain saw cut. This could also be either a lack of bar and chain oil ( tank empty, restricted oiler hole ) or an inferior type of oil that is being slung off the chain and not lubricating.
When should a chainsaw sprocket be replaced?
The chain sprocket must be replaced if the depth of the wear marks reaches about 0.5mm, i.e. the wear limit. A seriously worn chain sprocket can cause the chainsaw chain and guide bar to wear at an increased rate, as well as reducing cutting performance too, so it’s important to keep an eye on.
How many times can you sharpen a chainsaw?
Cutters can be sharpened up to 10 times or more before the chain needs replacing. If your cutters are worn unevenly after a few sharpenings, a professional can regrind them to uniform shape. If you use the same chain for a few years, then buy a new one, the new one won’t mesh smoothly with the sprocket and bar.
Why do loggers Run chainsaw bars upside down?
Every chainsaw bar has been designed to be mounted right-side up or upside down. The reason for this is that it allows the user to extend the life of his chainsaw bar by 50%. Flipping the bar will give the heavily-used areas some relief from wear and tear.
Why does my chainsaw blade dull so quickly?
Is the wood that you’re cutting with the chainsaw particularly dirty? Many chainsaw enthusiasts have noted that their blades dull faster when they’re cutting muddy wood. If the logs that you’re cutting up are muddy, then perhaps that is the sole reason why your blade is dulling too fast.
What chainsaw chains do professional loggers use?
Full-chisel teeth chains are usually used by professionals on large saws. Semi-chisel teeth are rounded, so the risk of kickback is less, and they stay sharper longer. Semi-chisel teeth cut slower but are a better choice in dirty wood than full chisel.
Should you run a chainsaw at full throttle?
Engine Protection Generally, two-stroke chainsaw engines are built to conveniently run at full throttle without an engine breakdown. Therefore, running at any throttle speed below the full throttle is not advised.
Can a bent chainsaw bar be straightened?
Solid body bars with replaceable noses can be straightened by hammering with the bend peak up on a flat anvil. Laminated bars need a piece of rubberized belting of approximate 1/4″ thickness between bar and anvil to properly hammer straighten .
Can you use a chainsaw to cut tree roots?
Once you’ve sliced the stump almost all the way to the ground, continue cutting it — and the soil — diagonally and at different angles. Don’t go more than a foot into the soil. Chainsaws are powerful machines, and you don’t have to worry about dirt damaging it or knocking the chain off.
Why is my chainsaw burning the wood?
Your chainsaw burns wood because of poor lubrication Lubrication allows the mechanical parts to coordinate much better by avoiding a phenomenon of friction which risks causing traces of burns. This is one of the main reasons that your appliance gives off too much heat and that the wood burns.
Will 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.
What is dressing a chainsaw bar?
A tool designed to preserve your guide bar. This maintenance tool removes normal wear and minor damage as it dresses your bar rails back to a 90-degree square edge. Redress your STIHL chain saw guide bar rails to 90 degrees to keep the saw chain cutting straight.
