Without the world’s most innovative chainsaw brand, Husqvarna, the forestry industry won’t be complete. But like most powerful machines, it develops issues over time, and these instances are inevitable considering how much work this machine is.
Let me share some of the common problems I’ve encountered with Husqvarna chainsaws and the solutions I’ve found to be effective.
Are Husqvarna Chainsaws Any Good?
The Husqvarna brand chainsaws have been coined as one of the best chainsaws ever invented, brought about by its impressive performance in the forestry industry.
Aside from the reputation of the Husqvarna chainsaws, what sets them apart from other chainsaw brands is their quality and rich history in the chainsaw market.
9 Common Husqvarna Chainsaw Issues + How to Troubleshoot Them
Problem #1: Husqvarna Chainsaw Won't Start
Defective Ignition System
One of the reasons a Husqvarna chainsaw won’t start is a faulty ignition system. Ensure there are no spark plug issues and it is functional for ignition. If the spark plugs are not working as expected, check for the ignition coil, and assess the defect for a replacement. Clean the corrosion with a steel brush to ignite sparks.
Ignition Coil
To inspect a defective ignition coil, use an ignition coil tester. If it is, then time to use that reserve.
Clogged Carburetor
To drain a clogged carburetor, yank the pull start repeatedly until all excess fuel comes out. Leaving the oil for a long time on your chainsaw is the common culprit of clogged drains. For this task, you may need to use the right Husqvarna carburetor adjustment tool for disassembling and assembling the parts.
Contaminated Oil Ports
Oil leaks are common on Husqvarna chainsaws, brought about by their two oil inlets, so make sure to learn how to store a chainsaw without the oil leaking. After using it, clean it with a small and sharp wire to prevent oil contamination.
Cold Weather
Weather conditions can impact chainsaw engines, causing them to become inactive, especially in cold temperatures. Whenever I’ve encountered this, I’ve found using the choke function to be particularly effective when starting up the chainsaw the next time.
Recoil Starter
Your engine will turn defective without the recoil starter assembly engaging the crankshaft. Inspect closely by pulling and releasing the start rope until it starts the internal combustion process. If it doesn’t, replace it.
Damaged Rewind Spring
If the problem you’re encountering is due to damaged rewind springs, we suggest not opting for repair because it won’t work either.
The rope will not recoil onto the chainsaw pulley if there are damaged springs. Always replace the recoil starter assembly because it’s cheaper than buying an entire kit.
Problem #2: Husqvarna Chainsaw Stalls
Dirty Fuel Filter
Damage to the fuel filter is often brought about by bad oil that has settled too long on the tank, which is one of the reasons why a Husqvarna chainsaw stalls.
The thick and sticky fuel can block the fuel line of the chainsaw engine, causing it to stall. Replace old oil with a good quality fuel mix to fix a faulty fuel filter.
Clogged Air Filter
Debris and dirt can get in the way, causing dirty air filters. When this happens, gas fumes are sucked instead of air. This will cause your chainsaw to stall, or should it work.
The engine will be too noisy, and running with a clogged filter will result in more carbon deposits. Regularly replace your air filter as part of chainsaw maintenance.
Defective Spark Arrestor
I’ve noticed that a defective or clogged spark arrestor can indeed release hot sparks, which pose a fire risk. Though it’s just a small screen, the spark arrestor plays a critical role in preventing these dangerous sparks from the engine. If it gets clogged, the exhaust doesn’t function properly, leading to the engine stalling. Always something to keep an eye on.
Problem #3: Husqvarna Chainsaw Not Cutting
Untuned Chain
Chainsaws require stretch and tension in strings, which means the wrong chain direction will not cause enough tension, preventing you from cutting.
Tuning your screw adjustment is also essential as loose screws can cause chain displacement, leading to less or no vibration on your saw when you run it.
Chattering Chain
It’s common for chainsaw teeth to dull out after several uses because the gutting edges face pressure when sharpening.
Compared to the other parts, we also noticed that the chain is the component that gets worked out the most, causing chattering. The curvy cuts from the wood chips cause the chain to be sharpened, requiring a separate round filer depending on the model.
Worn Out Chain Bar
Worn-out chain bars can cause the chainsaw to stop cutting. More often than not, the root cause is improper lubrication or a bent bar. I always make it a point to lubricate with chain oil and to replace any bent bars without delay. It’s a simple practice that can save a lot of hassle in the long run.
Defective Clutch
The clutch pads get worn out when there’s not enough pressure on the clutch drum. A faulty clutch is bad for your chainsaw. When this happens, you will have to replace the whole clutch assembly immediately.
Problem #4: Husqvarna Chainsaw Won't Stay Running
One of the common Husqvarna chainsaw problems is that it won’t stay running. The possible perpetrators of this problem are old fuel, dirty carburetors, and clogged vents.
Ensure you check the following factors to avoid the stress and cost of getting professional service for repair.
Problem #5: Husqvarna Chainsaw Keeps Turning
Defective return springs and malfunctioning clutch will prompt chainsaws to continue turning even after it was shut off. There’s no other way to fix sticky clutch pads than by replacing them.
Problem #6: Husqvarna Chainsaw Has Stiff Guide Bar Grooves
To fix a stiff bar groove, detach the drive case cover, and disassemble the chain and the bar. Clean the grooves with a small screwdriver and a file to flatten the nicks.
Problem #7: Flooded Engine
An overdone fuel pump will prompt flooded engines on your saw. Drain all the fuel in the saw’s fuel tank and turn the throttle while pulling the cord to fix issues like this quickly. After this procedure, you can deactivate the choke and clean the left-out residue.
Problem #8: Husqvarna Chainsaw Vibrates
Too much vibration on your chainsaw often occurs due to loosening chains. To fix this common issue, use the built-in tension adjusters to tighten the teeth.
Maintenance and Care Tips
Following simple maintenance tips is the precaution you should consider to keep your machine functional and in good operation.
Tip #1: Regular Cleaning After Each Use
I can’t stress enough the importance of thoroughly cleaning a chainsaw, not just the parts that catch the eye. I always make sure to keep my chainsaw free from debris both before and after use. It’s a proactive step to prevent issues, especially around the sprocket nose, inlet hole, or groove bar.
Tip #2: Rotate the Guide Bar After Chain Replacement
Rotate the guide bars manually and remove the burrs after sharpening the chains.
Tip #3: Inspect Chain Tension and Lubrication
When purchasing your chainsaws, ensure it gets proper lubrication to avoid rusting your chain early. Always conduct regular inspections of chain tension to avoid stiffness during operations.
Tip #4: Maintain the Sharpness of the Chain
Chainsaw chains should always be kept sharp to avoid miserable working conditions when working on your machine. Use the proper file size and file at the correct angle to keep sharpness.
Tip #5: Check the Cleanliness of the Air Filters
One of the common problems with Husqvarna chainsaws are clogged air filters. Keep air filters well maintained through regular cleaning or periodic replacement.
When the saw is left at idle speed, it results in worse carbon collection. Utilize compressed air to clean the filter easily.
Tip #6: Avoid Racing the Engine
Never overwork the engines when cutting. It may be one of the most powerful tools, but it’s required that you use the appropriate cutting techniques to avoid racing the engine.
Tip #7: Always Use Fresh Gasoline
Fresh gasoline is king when maintaining a Husqvarna. Unlubricated teeth often cause a dull chain.
Weather factors affect the oil mixture causing it to break down easily when left sitting on your saw. This is why it’s recommended never to mix fresh gasoline with old fuel to avoid Husqvarna chainsaw starting problems.
