Where is the fuel filter in a chainsaw?

Change air filter every 2 months, fuel filter every six months

Chainsaws have 2 filters. an air filter and a fuel filter. Household models have a felt air filter. It is not cleaned, but replaced, because blowing does not clean the dust completely. The frequency of replacement is as follows: if you work with a chainsaw 2-3 times a week, change the filter once every 2 months.

The life of the fuel filter depends on the quality of the fuel mixture. And the quality of the fuel mixture depends on what you store it in. The most common mistake is storing gasoline or mixture in a regular plastic bottle. You can not do this, and here’s why: gasoline corrodes common plastic, the small particles get into the mixture, during operation settle a thin film on the filter. The result is the same story that started this article.

When to change the fuel filter? If your chainsaw occasionally shuts off and doesn’t hold back, the filter is probably clogged. Take it out, blow with a compressor from inside to outside (not the other way around). If it is hard to get air in, you have a filter clogged with a film of mixed fuel stored in an unusable plastic container. You need to change such a filter. When using a properly stored mixture, the filter should be changed every six months if using a chain saw 2 to 3 times a week.

Never operate the machine without filters or debris will get into the engine.

Before you put the chainsaw away, drain all the fuel from the tank and let the rest run out: start the saw and wait until it shuts down.

Partner 350 chainsaw: replacing fuel hoses

I have an old chainsaw Partner 350. Lately I use it on weekends, doing chores and I don’t usually drain the gasoline. But I had it in the trunk without work for almost a month, and the next time I tried to start it, it did not work. Inspection showed that the fuel hoses in the tank had dissolved and crumbled, as well as torn so-called primer (fuel pump on the side).I was looking around on the web for those hose changes and I found a couple of videos that showed how to do it and realized that it was not an easy procedure. the openings in the tank are very narrow and it is hard to get the hose through.

Left side is the tank vent. The fuel filter is connected to this hose in the tank. This hose connects to the carburetor on the right.The outlet from the carburetor on the left side connects to the primer, and from the primer hose goes to the right hole, in the tank.

The opening on the left is wider than the one on the right and the hose fits into it a little easier. The hose itself is the same diameter at these portions. The thinner hose is used in the “carburetor outlet. primer” section. I left the old hose there as if you install a new (thicker) one, it will interfere with the throttle lever actuator. Perhaps if it is somehow curved, the problem will be solved, but the shape will be difficult to find. I tried to replace this hose with a hose from a dropper. outwardly it looks thinner, but the wall of the tube is thin and the inner diameter is even larger than that of the thick hose.

How to get this tube through these holes correctly, I don’t know. I’m on a 2-3 cm bite along the tube 20-30% of the tube wall, so it can already fold and pass through the hole.

After slipping through, pulled what appeared to be there with the narrow pliers from the tank. Goes well. Pulled out as much as I needed, cut off my stump and put a fuel filter in the tube.

Didn’t go so well with the second tube. Tried to do the same technique, but the hose is very heavy. managed to pull out less than a centimeter and the hose broke off. But I figured since it’s the return, that would be enough.

I assembled it, primed it, pumped it up, saw started, nothing seems to be dripping.When pumping the old primer was usually completely filled with gasoline, in this one you can see an air bubble, but the engine seemed to work fine. I’ll check it out this weekend.

Design features of the Partner 350 chain saw

The reliable and user-friendly saw of this model has a gasoline engine with the power of 1300 W. It is distinguished by an easy start-up, which is due to the integrated professional fuel pump and electronic ignition system.

The chainsaw is equipped with a safety system that automatically activates the twin inertia chain brake. Chain lubrication is also automatic. Changing the chain tension on this machine is very easy with just two wrenches.

The chainsaw is equipped with a fuel primer that makes it easy to start in any season. The tool’s starter drum is equipped with a special impeller that cleans it from dirt.

CCS filter traps all residual particles. The air filter can be used for a long time, saving fuel at the same time.

What is a chainsaw fuel filter??

Gasoline filter for chain saw ( felt) is an obligatory element of the working mechanism of the whole system. Their main purpose is to clean the fuel entering the tool from all unwanted particles that are in the fuel. It prevents particles like dust, rust, water, etc. from getting into the fuel line.

If a chainsaw was not equipped with a chainsaw filter and the fuel would come in a clean form, then absolutely all dirt particles, any foreign substances would get straight into the engine, clogging all the channels. Of course, such pollution would quickly put the engine out of operation.

Now let’s talk about the chainsaw air filter

Husqvarna | When To Change The Chainsaw Fuel Filter?

A chainsaw is equipped with an internal combustion engine. It is very important that the air that enters this kind of engine is clean and filtered enough. This is a very important condition for the stable operation of your tool. Provides the function of cleaning the incoming air flows into the engine an important part of the chainsaw mechanism. the air filter for the chainsaw. During its operation, the air in its radius of action is heavily contaminated with sawdust, wood dust, etc.д.

What happens if the air filter is clogged or just contaminated. If the filter fails, the air flow to the carburetor is immediately reduced. Because of the lack of air, the carburetor forms a mixture, and the fuel during these processes will not burn completely. These processes will cause your engine’s power to be significantly reduced and your fuel consumption to increase.

fuel, filter, chainsaw

Separately I would like to say about the range of this group, despite the fact that it is called a filter for chainsaws, in it we have collected a lot of other stuff that does not deserve a separate group:

  • housing covers;
  • fuel and oil tank covers;
  • springs and shock absorbers;
  • chain tensioners;
  • flap pulls and suction tubes
  • switches;
  • mufflers and tanks.

A word or two about the maintenance of the filter element

Therefore, it is necessary to deal with its cleaning in a timely manner. Cleaning is necessary not only when the tool is removed during repair, but also after a long and dirty run.

There are chainsaw models that use centrifugal forces to pre-clean the air. This is done in such a way that the flywheel impeller twists the incoming air currents, as a result, all impurities are ejected from the intake pipe going into the fine filter. Usually, thin filters of this kind are made of diffusion foam, nylon mesh, and other materials.

Summarizing all of the above, we can say with confidence that our store is Benzograd is almost the ideal place to buy a filter for chain saw, thanks to the wide range, easy navigation and low prices.

Flushing a chainsaw air filter

The instructions for any saw make cleaning the air filter element one of the procedures you must follow after each use.

How to wash a chainsaw air filter:

  • Unscrew top cover. You will find the necessary compartment on top of the housing near the handle, regardless of brand, whether it is Husqvarna, Sturm, or Partner.
  • Take out the filter it can be nested or screwed on.
  • Wash the foam filter with warm water and soap and air dry. Cleaning with gasoline shortens the filter’s service life.
  • Paper, wire, or felt filter may be shaken loose by lightly tapping edge against a hard surface. They are also well cleaned/blown with a compressor or vacuum cleaner.
  • All dirt in the area around the engine should be wiped off.
  • Put the chainsaw air filter back in place, making sure all the grooves and parts fit snugly into place. Close the cap and tighten the screws.

If the filter began to deform, became more dense and thin, there were holes and cuts it must be replaced.

How a chainsaw carburetor works. peculiarities of airflow

The principle of operation of a chainsaw carburetor also includes the supply of air mixture into the device. As you understand the combustion chamber receives not pure fuel (oil with petrol) but a fuel mixture. oil with petrol from the tank and air, which previously goes through a filter element.

So, the air passes through the filter, and enters the unit through the diaphragm number 7.

Air damper 7 is almost fully closed during cold start, as shown in the diagram. There is a small amount of air flowing into the system through it. The air goes into the diffuser 16. Under the number 12 are designated channels or jets idle and medium speed. These channels are interdependent, that is, the mid-rpm channel is a transition channel from idle. These channels are constantly open, so the fuel in the appropriate dosage enters the diffuser, where it mixes with the air, heading to the cylinder.

Under number 15 is marked the channel of maximum speed, which consists of a valve with a rubber base. Through this valve, fuel is fed in one direction. to the diffuser chamber. Then the system is entered throttle valve 8, the movement of which depends on the force of the unit throttle. When starting, the valve is in the vertical position, so the chainsaw works only with fuel mixture coming from the idle speed channel. The amount of air is small because the butterfly valve 7 is also open by a few millimeters. When the tool trigger is pressed the flap is tilted by 10-15 degrees and as a result the fuel mixture is supplied from the mid-rpm channel 12 in the diagram above.

When the sawyer starts sawing wood, the RPM increases to maximum, so the flap moves up to 90 degrees from its original position. Fuel quantity increases and speeds up combustion of the fuel mixture.

In order to fill the chamber 14 with a fuel mixture made of petrol and oil, which flows through the channel closed by the needle, it is necessary to create a vacuum due to which the diaphragm 13 will be drawn inwards, thereby acting on the rod. The vacuum in chamber 14 is created when the starter grip is jerked as the tool crankshaft moves. The piston moves up and down when the recoil starter is jerked, which generates pressure inside chamber 14. As a result, the chamber is filled with fuel, which flows through the appropriate channels into the diffuser, mixing with the air, and heading into the cylinder.

After the engine of the unit will be started, the piston begins to move under the influence of the combustion mixture, so the vacuum in the chamber is formed constantly, which actually provokes the sagging plate 13, acting on the needle valve, through which fuel enters the main chamber of the carburetor chainsaw.

This is the principle of the diaphragm-type carburetor, which does not depend on the angle of positioning. Knowing the construction and principle of operation of the unit, you can proceed to its adjustment, cleaning and adjustment.

Final carburetor tuning

Slowly turn the maximum and minimum revolutions adjustment screws (H and L) clockwise as far as they will go and then turn them one and a half turns in the opposite direction.

Read Why Mint is bad for men

Start by warming up the engine for 5-10 minutes (not at high rpm).

Now, by turning the idle speed screw (T, LA, S) counterclockwise adjust the minimum number of revolutions, at which the engine is stable. The chain should not move at all. If the engine stops when idling, turn the idle speed screw clockwise accordingly. If the chain moves, turn the screw counterclockwise.

For the final carburetor adjustment of the chainsaw, check the engine acceleration and maximum rpm.

Checking the acceleration

Gently push down on the gas pedal and see how fast the engine revs up from idle to maximum power. If the engine revolutions are slow, it is necessary to release the L (low speed) screw by turning it anti-clockwise (not more than 1/8 of a turn).

As mentioned earlier, the maximum RPM is adjusted with the H screw, the RPM increases when it is turned clockwise, decreases when it is turned counterclockwise.

The maximum rpm for the engines of petrol chain saws is 11 500-15 000 rpm depending on the model. A higher speed is dangerous for the engine, which will not allow it to start. The maximum rpm can be determined by the ignition interruption. If it does, turn screw H counterclockwise.

Once we have adjusted the acceleration and maximum RPM, we again check the engine’s idle performance. We will know we have adjusted the carburetor correctly if:

If at least one of these conditions is not met, adjustment should be repeated (excluding the basic step).

How the chainsaw carburetor works

Before adjusting the carburetor on a chainsaw, you need to understand the principle by which it works.

  • When the engine is started, the air damper in the lower part of the housing opens.
  • In the air duct and the float chamber, a vacuum is created by the stroke of the piston, as a result of which a stream of air is sucked in through the diffuser.
  • The air intake intensity is controlled by the position of the air intake damper.
  • Gasoline flows through the inlet fitting from the gasoline tank into the float chamber.
  • The rate at which the gasoline flows from the chamber to the diffuser is regulated by the nozzles.
  • The gasoline is mixed with the air in the diffuser.
  • The prepared air-fuel mixture enters the inlet passages, from where it is directed to the working combustion chamber of the cylinder.

Evaluation of the condition of the cylinder-piston group

Low cylinder pressure is often the cause of engine starting or performance problems. This can be caused by wear of the piston or cylinder, retracted piston rings, worn bearings. It is possible to examine partially the condition of the cylinder-piston group (CPG) by removing the muffler and looking through the opening.

A compression gauge placed in the spark plug hole can measure compression in the engine. the measurement also provides information about the condition of the cylinder and piston rod. Accurate data is obtained only after complete disassembly of the mechanism. If there are chips or scratches on the piston, it needs to be replaced. Piston ring must be clean, free of carbon buildup, and must be in the correct position.

Piston and crank mechanism wear and tear is considered to be a serious problem

You can use the compression test to check the condition of parts of the cylinder head

Diagnosing a Partner 350 chainsaw

Correct diagnosis is more than half the repair. In the case of malfunctions related to the fact that the saw does not start, the essence of diagnosis is to check the spark and the presence of fuel in the cylinder, i.e. к. there is either nothing to burn in the chainsaw or nothing to ignite.

Checking spark

To check the spark, unscrew the spark plug, install it in the cap of the high-voltage wire and put it to the cylinder (there should be a mass on the spark plug). Next, pull the starter a few times while closely watching the spark plug. No spark if your Partner 350 chainsaw has malfunctions such as:

  • Defective spark plug (can only be eliminated by replacing it with a known good one);
  • Broken wires in the system;
  • Failure of the ignition control button;
  • defective ignition coil;
  • Absence of backlash between the coil and the flywheel;
  • a broken key between the crankshaft and the flywheel.

Check fuel

The first sign that the cylinder is not getting fuel is a dry spark plug. If you notice a dry spark plug, the next thing to do to pinpoint the problem is to try and start your Partner 350 chain saw by pouring under 5 ml of gasoline through the spark plug hole into the cylinder. If after that the chain saw doesn’t start, it most likely has no or insufficient compression to start the engine. Causes:

If after filling the spark plug with gasoline the saw will start, there is a problem with your Partner 350 carburetor or fuel line. Need to do a complete fuel system diagnostic.

How to replace the chainsaw’s fuel filter

Bearing diagnosis

While doing a chainsaw diagnostics it is necessary to check the crankshaft bearings for clearance. You do this by wiggling the flywheel up and down. If there is play, the bearings must be replaced.

Also remember to check the crankshaft crank end play. To do so, lock the piston in its highest position and rock the flywheel back and forth a little at a time, simulating natural movement. If there is play, the Partner 350 crankshaft must be replaced.

Fuel filter for chainsaw

If you are interested in chain saw fuel filter then it means your chain saw has long been your reliable helper and indispensable tool at work. Regardless of whether you use the chain saw for daily felling or for limbing, all the chain saw parts need to be changed in time several times a year.

A chainsaw fuel filter works by cleaning the fuel on its way to the carburetor from foreign particles that can clog the carburetor’s piston system if the filter fails. Such a widespread problem as a chainsaw engine shutting down while idling is most often caused by a clogged fuel filter. In some cases, cleaning the chainsaw fuel filter and removing the fuel filter on the chainsaw fixes the situation, but experts still recommend replacing this important unit.

Filter for chainsaw

What to do if your favorite tool, a chainsaw, fails? it is necessary to replace the chainsaw filter, but where it is located and what actions to take, let’s look at it all in detail. A chainsaw, a very important and almost indispensable tool for woodwork. The tool is very simply built, but has small details and nuances. Uses a gasoline engine, most often with one cylinder. The fuel system is built in the form of a tank, which can be of different volume. Fuel consumption depends on tank capacity and intensity of use. The chainsaw has a manual priming pump for easy and convenient starting. What to do if the chainsaw air filter is clogged During operation, the chainsaw takes air-fuel mixture, which is formed in the carburetor. To prevent dirty air from entering the system and damaging the engine, it is passed through a special cleaning filter. Depending on the model of the tool, cleaning is carried out with a centrifugal system. Chainsaw filters are made of foam, nylon mesh, and other materials. Given that when working with a chainsaw, the air is contaminated with dust, fine chips. If the chainsaw filter is very dirty, it must be either replaced or cleaned. Because it reduces the air supply to the carburetor, which leads to a reduction in the power of the chainsaw. Most often the filter is cleaned by purging or flushing, but it all depends on the material. The cleaner the air gets into the system, the longer the life of the chainsaw.

How To Replace a Chainsaw Fuel Filter

In order to replace the filter in the chainsaw, the following steps must be taken:

Remove the chainsaw air filter cover.

Under the cover placed the filter itself, you must use a screwdriver to unscrew the mount.

fuel, filter, chainsaw

Remove the old filter and replace it with a new one.

Close the lid, you can use the equipment.

If the chainsaw began to jerk or make a “sneezing” sound when running, the problem is due to clogged filters and air intake ducts. After you have flushed or blown the air intake ducts completely, you may work with your tool again. A chainsaw is not a very complicated tool, the main thing is to understand and understand the working principles of each individual element. But alas, not everyone can and does understand the mechanics. There is nothing bad or terrible, you need to find a good and competent service that will help you solve problems with the chainsaw filter or other breakdowns.

GoodLuck 4500/5200 chainsaw fuel filter (bracket)

The fuel filter is a very important filter element in a chainsaw, this small and unimportant at a first glance detail plays an important role. Before gasoline and oil enter the carburetor, the fuel filter cleans it from debris. For long service of the carburetor and the whole chainsaw, the gasoline filter should be changed once a season, but it also depends on the quality (degree of contamination) of the gasoline and here for each chainsaw requires its own control. If you began to notice that your chainsaw at high revolutions begins to stall, in this case you must first pay attention to the gasoline filter, if it is the cause, it should be replaced with a new one.

There is a story that the gasoline filter can be washed with a soapy solution or with a compressor. After many years of working in the field we have seen many things, and we can tell you only one thing with certainty:. Do not waste time, it will not save your fuel filter. Debris is clogged deep in the fibers and you can not wash or blow it out.

Cleaning a chainsaw carburetor and how to do it right

One of the most important mechanisms of a chainsaw is the carburetor. It is designed to dose the fuel-air mixture into the engine cylinder. Without this mechanism, the engine can not work, and it is often the cause of instability of the engine. To fix the situation, you will need to clean the carburetor of a chainsaw, which you can do yourself.
