Chainsaws feature saw blades attached to chains wrapped around metal guide bars, powered by either a small one-cylinder petrol or electric engine (sometimes powered via cord or battery) engine, with noise reduction features like mufflers and an anti-vibration system for increased cutting comfort.
Fuel can absorb moisture, forming a sticky film that coats its surfaces and can become unusable if left sitting for too long. To avoid this happening, ensure you regularly empty and clean out your chainsaw gas tank!

1. Use a siphon
When storing chainsaws for long periods, it is vitally important that they are regularly cleaned. This will prevent malfunctioning when using them; old gas can damage carburetors, spark plugs, and other parts of the saw as well as cause rust to form on its parts. To avoid these problems, a siphon should be used to extract old fuel from its tank before adding an additive to keep your gas fresh for an extended period.
Before opening your fuel tank, it is wise to wipe it down with a rag to eliminate any dust that might settle and prevent any chance of it clogging your carburetor and leading to malfunction in your chainsaw. Furthermore, be sure to also regularly check and clean your air filter so as not to allow dust into your carburetor and cause unintended problems for your chainsaw.
Siphoning old fuel from your chainsaw’s gas tank can help remove it quickly and safely. First, find an open space without obstacles or barriers; open the fuel tank; insert straight portion of siphon; open drain hose from siphon to can; connect drainage hose from siphon for collecting old gas; repeat siphoning until all old fuel has been collected – siphon until all has been taken.
Before draining your chainsaw’s fuel line, disconnect its fuel line by taking steps such as removing its plastic guard and small clamp. A screwdriver should be used to access and disassemble these parts as some gas and oil may leak from them when removed. Be mindful when doing so since some gas may also escape through these leaks.
2. Use a fuel additive
If your chainsaw has been sitting idle, fuel additives could be just what it needs to keep running at its optimal levels. Fuel additives remove gummified residue that clogs carburetors and engines as well as cleaning out its carburetor and fuel lines – an integral step toward keeping your chainsaw running at peak performance.
Start by finding an open area where you can empty your chainsaw’s gas tank. Before opening its lid, wipe down with a damp cloth to avoid dust from entering and clogging up its carburetor – otherwise your chainsaw won’t start! Unhooking its fuel line from its tank may require undoing screws or clips before pouring the old gasoline into a container and disposing it according to local and state regulations.
Your chainsaw’s fuel will begin to degrade within a month due to lost combustible properties of gasoline. With proper care, however, this should last at least 12 months. Store any unspent gasoline in an airtight container to extend its shelf life further.
Use of a fuel additive is an easy and quick way to flush gas out of your chainsaw. Simply add a few drops of cleaner to the fuel tank, pull on it with alternate pulls and pauses and watch as the cleaning agent helps dissolve any deposits in the carburetor and fuel lines. Alternatively, mix this additive with fresh fuel before taking action against any remaining residue in the tank.
3. Use a brush
If you have been using a chainsaw for some time, it is advisable to regularly clean its gas tank in order to prevent old fuel from damaging it and also utilize a fuel additive that protects from degradation of its contents – available from most hardware stores.
First, open and drain the gas tank of your chainsaw. Make sure to do this in an area with easy cleanup, wearing protective gloves. A brush may also help clean out its interior; specifically designed cleaners should also be utilized.
If your chainsaw has been lying idle for longer than one month, you should remove its spark arrestor as well. This screen helps prevent sparks from flying out of its engine and may become clogged up over time due to debris accumulation. Consult your local fire department if any gas needs to be disposed of as they may provide advice as to where best to dispose of it.
Clean the air filter of your chainsaw as part of its routine maintenance. This plastic or metal device filters dust and dirt out of the air for efficient functioning, so a clogged-up filter should be replaced immediately.
Once your chainsaw has been thoroughly cleaned, add fuel additive to its fuel. This will protect it from breaking down and make sure that it runs as it should. Fuel additives are readily available at hardware stores and provide an inexpensive yet effective way to ensure proper functioning of your chainsaw.
4. Throw in some BBs
If your chainsaw engine has stopped starting or you notice extra white smoke, it could be that its fuel has soured. To protect its internal components and maintain efficient performance in the future, it is vital that this issue is rectified quickly before any lasting damage is done to it.
An accumulation of fuel in a chainsaw’s tank can create many issues, from its carburetor becoming clogged to degraded fuel turning to gum, hindering engine function. You can prevent these problems by draining and refilling with fresh fuel regularly.
Carburetor cleaner can also help to get your chainsaw’s fuel system clean. By breaking down gum-residue and clearing passageways of any build-up, carburetor cleaner allows fuel to flow properly again. Pour the cleaner into your gas tank, start your chainsaw at low RPMs for several seconds after pouring it in, and let it do its work before running at higher RPMs to flush through all passageways and passageways.
One way to ensure that your chainsaw runs smoothly is to regularly clean its spark arrestor screen. Over time, this screen may become clogged with dirt and sawdust from normal use or become damaged from old gas that has degraded over time – to properly clean it, you must remove and clean out its filter, before reinserting it back into its socket.
Add some BBs to the tank of your chainsaw to clean its gas tank safely and effectively. Doing this may seem bizarre, but the small balls will dislodge any debris inside that could clog its fuel line later. Be sure to do this in an open, ventilated space.
5. Clean the gas tank
Staying away from your chainsaw for extended periods can cause the gasoline inside to go bad and clog its carburetor and fuel system, making it harder for it to start up again. Therefore, maintaining its good working order is vital. When cleaning your gas tank you have two options for doing so: using a tank cleaner or water; however before beginning either process remove the spark plug and clean out its carburetor to save yourself money by not purchasing fuel that no longer benefits your engine.
If you’re using a tank cleaner, always read and follow the directions on its bottle. Some cleaners require that you leave them in for a certain length of time before emptying out your tank, while others don’t require this step. Be sure to also read any warning labels attached to its label to be on the safe side.
Before beginning to clean your tank, it is also wise to wipe down its exterior in order to prevent dirt from entering and clogging a fuel line. Also ensure that you use an appropriate cleaner for your type of chainsaw.
Once the tank has been thoroughly cleansed, add new fuel and start your chainsaw. If this doesn’t work, combine some carburetor cleaner with your fuel and run at lower RPMs or idle speeds – this should remove any sticky deposits clogging the intake components that could reduce engine power and speed.
If your chainsaw won’t start, it could be because its needle valves are clogged with propane deposits. A carburetor cleaner and brush should work to clear them out; once finished, dry them before reinstalling the needle valves so the cleaning agents drain from them properly.
