To get the solutions to your chainsaw problem let’s get into the discussion. After going through this post you will get complete knowledge of this issue. 

Why Does It Commonly Happen?

Modern engines are designed to stand against many severe problems. But sometimes some tiny problems can be crucial and that can make your chainsaw stop working. Running out of gas is one of them. It’s tiny but crucial.

Now come to the point. Why does it happen? Here are the three reasons along with the solutions:

This table will help you to be more specific. You will get an idea here of what to do to get out of this problem.

Reason Solution
Fuel filter blockageClean and blow through the filter
Particles at the bottomObserve and remove all the dirt
Get air in the fuel pipeOn and off position priming

For your convenience, here we will discuss 4 reasons in detail with appropriate solutions.

Reason 1: Blockage in the Fuel Filter

If you keep unused your chainsaw after running out of gas, it can stop getting started. Because fuel can not be transferred to the operating part of the engine. That’s why chainsaws can not perform well. 

Sometimes it stops working as well for the fuel transformation issue. For the proper operation of the engine, proper fuel transformation is very compulsory

Solution:

To apply this solution, first, you need to remove the fuel filter. Then check through it. Observe it nicely and find out if there is any blockage.

Then blow into it. Look if the air is obstructed or not. If air is obstructed in the filter then clean it thoroughly. 

After cleaning the filter properly, try to start your chainsaw again. And you will find it working. 

Reason 2: Particles at the Bottom of the Fuel Tank

After running out of gas your chainsaw fuel tank attracts dirt into it. In this case, particles and debris are deposited at the bottom. That makes the engine stop working

Because the dirt and particles make the barrier in the fuel transformation path. That ultimately stops your chainsaw from working. 

Solution:

In this case, first, remove all the leftover fuel from the tank. Then take a torch to observe the bottom of the fuel tank. And look if there is any dirt, particle, or sediment at the bottom. If so then clean all the dirt carefully.

Lastly, refuel the tank and try to start the chainsaw again.

Reason 3: Air in the Fuel Pipe

If the chainsaw runs out of gas, air can get into the fuel pipe. If air gets into the fuel pipe, it will hamper the work of the engine.

Getting air into the fuel is a major problem why your chainsaw does not start. The empty tank let the air get into the fuel pipe. So be careful with this issue.

Solution:

If air gets into the fuel pipe, priming will be able to remove that. To do this, first, fill the fuel tank. Now take the fuel tank to the “off” position. 

Then take it to the “on” position. Do it repeatedly three or four times. It will help to remove the air that got into the pipe.
