8 Causes of SENIX Chainsaw Smoke (Chain & Exhaust)

When you are attempting to figure out why your chainsaw has begun to smoke, the first thing you will need to do is locate the source of the smoke and establish whether it is coming from the bar or the exhaust. Put an end to the running of the saw so that you don’t create any more complications or harm.

Increased friction between the bar and chain may cause a SENIX chainsaw to smoke. This increased friction might be caused by a dull chain, a tight chain, a blocked oiler, or inadequate amounts of bar and chain oil.

Smoke may also be produced by a SENIX chainsaw if the engine has the incorrect amount of engine oil, there is water in the fuel system, or the air filter is clogged.

The Following Is the Reason That a SENIX Chainsaw is Smoking:

  1. Chain that is either dull or has been improperly sharpened
  2. Chain is pulled excessively tightly.
  3. Oil container for bars and chains that is empty
  4. Bar and chain oil of the incorrect kind
  5. Clogged oiler
  6. Plugged air filter
  7. Insufficient engine oil or an excessive amount of engine oil in the crankcase
  8. There was water included in the gasoline mixture.

When diagnosing issues and making repairs on your chainsaw, use extreme care. Remove the spark plug boot after turning off the chainsaw, waiting for the engine to cool down, and then doing so.

Chainsaw smoke coming from the bar and chain of the SENIX chainsaw

If you observe smoke coming from your chainsaw whenever you apply pressure to the bar while cutting, you should start searching for objects that might increase the friction between the bar and the chain.

This might be the result of a poorly lubricated chain, a chain that is too stiff to travel smoothly over the bar, or a combination of the two.

Chain that is either dull or has been improperly sharpened

Not only will you have a difficult time cutting with a chain that is dull, but you also run the risk of your saw smoking as a result of this.

When cutting wood with a dull chain, you will need to apply a greater amount of pressure to the bar. Because of this additional pressure, metal-on-metal friction occurs, which generates heat and smoke.

Keep an eye out for these symptoms that the chain needs to be replaced:

  • In order to produce a cut, it is necessary to exert a greater amount of pressure on the bar.
  • When you chop anything, you end up with a lot of sawdust.
  • Chips or other forms of chain damage.
  • Rakers and teeth that are worn down.

You may hone the chains on your own if you want. If you do not have any prior expertise sharpening chains, it is strongly suggested that you have a trained professional do it for you. A chain that has not been sharpened properly poses a significant risk to anybody using it.

Oil container for bars and chains that is empty

When your chainsaw’s bar and chain do not get an adequate amount of oil, friction will begin to build up. It is possible that the oil tank is empty or that the oiler is blocked, both of which would cause this issue.

If the oil tank for the bar and chain is almost out of oil or completely empty, fill it.

Run your chainsaw at roughly half to three quarters of its power to determine whether or not there is enough oil on the bar. Keep your hands 8–12 inches above the ground as you hold the bar. It must should be possible for you to see a line of oil moving down from the bar onto the ground.

Check that the bar is in excellent condition and that the oil channel is not clogged if you are not obtaining enough lubrication. The worn or broken guide bar should be replaced, and the oil channel should be cleaned if necessary.

When you fill your SENIX up with fuel, you should make it a routine to also replace the bar and chain oil. This is an excellent practice to get into. On the other hand, if the oil that you are using in the saw is too thin, you may find that you go through oil at a quicker pace, in which case you will need to check it and replenish it more often.

Bar and chain oil of the incorrect kind

If you use an oil for your bar and chain that is too thin, you run the risk of damaging both the bar and the chain, as well as increasing the amount of friction, which may cause smoke to emanate from the bar. If the oil is too thin, it could not be able to adhere to the bar and chain, and it might instead slide off of it.

Be sure that you are lubricating your bar and chain with a high-quality bar and chain oil, such as this oil from Husqvarna.

Chain is pulled excessively tightly.

The chain will become less secure as you continue to use it, so you will need to check on it often and adjust it as necessary. However, if you tighten the chain too much, it will not be able to rotate freely around the bar, which will result in higher friction, which will cause smoke to be produced.

Adjust the chain tension on a SENIX chainsaw:

  • Take off the wire from the spark plug.
  • Release the lock on the chain brake.
  • Loosen the bar holding bolts in order to remove the cover that has been placed on top of the clutch. It is not necessary to remove the lid.
  • To relax the chain, turn the tensioning screw counterclockwise, and to tighten the chain, turn the tensioning screw clockwise.
  • When the chain is pulled away from the bar, there should be about 3 millimeters, or 1/8 of an inch, of space between the chain and the bar.
  • As soon as the appropriate tension has been reached, the bar holding nuts should be tightened.

You want the chain to be able to move freely around the bar while yet sitting in a secure position around it. It is important that it not be so slack that it hangs off the guide bar.

Chainsaw from SENIX Producing Smoke from the Exhaust

In the event that your SENIX chainsaw smokes while in operation, you will need to investigate difficulties with the airflow, such as a clogged air filter or a problem with the fuel mixture.

Obstructed air filtering system

When your chainsaw’s bar and chain do not get an adequate amount of oil, friction will begin to build up. It is possible that the oil tank is empty or that the oiler is blocked, both of which would cause this issue.
The use of a chainsaw is a very filthy occupation. Sawdust and smaller wood chips are being scattered in the air at this time.

In order to prevent dirty air from entering the chainsaw’s engine, you need install an air filter. Dirt and sawdust are prevented from entering the carburetor throat by the filter, which reduces the amount of wear and tear on the engine.

If you only use your chainsaw occasionally, you should change the air filter once a year and inspect it before each time you use it. If you use the saw on a regular basis, you should inspect the filter on a regular basis and change it out if it gets severely soiled or broken.

It is possible for the filter to get so clogged that air cannot move through it if it is not checked and cleaned on a regular basis to ensure that it remains in excellent shape.

Because the gasoline is too rich, the engine will smoke. It is possible that the engine will stop working altogether because there is not enough air.

Insufficient engine oil or an excessive amount of engine oil in the crankcase

Low level of engine oil: Air-cooled engine oil is what’s utilized to keep the engine cool and give enough lubrication, however the amount may be too low.

When there is not enough engine oil, the engine will generate heat that may become so intense that it melts engine components, and the oil will begin to burn and smoke. This can cause the engine to break down.

Too much engine oil: Filling the crankcase with an excessive amount of engine oil will prevent the engine components from moving smoothly. The crankcase will see a rise in pressure, and as a result, the components will be subjected to an increased load, which will generate heat.

Because of the increased pressure, there is a possibility that surplus oil may be forced into the cylinder, where it would catch fire and produce a bluish-white smoke.

There was water included in the gasoline mixture.

The presence of water in the fuel might result in the production of white exhaust smoke. Both the fuel system and the engine are susceptible to corrosion when exposed to water.

Instead of attempting to find out a method to conserve fuel and remove water, it is advisable to empty the fuel tank and replace it with new gasoline. This will ensure that the fuel is as efficient as possible.

To assist in the removal of moisture and the cleaning of the fuel system, using a fuel additive such as Sea Foam Motor Treatment is recommended. Turn on the saw and let it run for some time so that the treated fuel may make its way through the system.
