Echo CS-400: How To Start Your Chainsaw In A Few Simple And Easy Steps

Echo chainsaws are usually similar to each other in terms of starting procedures. They all require you to follow similar guidelines to get started, and the Echo CS-400 is no exception. There are top three things that should be on the checklist before getting started. These should be the fuel ratio, air filter, and spark plug. It is always quite confusing as to how we should start the chainsaw. One can read through the user manual to get started, or you can simply read till the end to know it all.

How To Start The Chainsaw?

Initially, it seems that starting the chainsaw is like a piece of cake. But honestly speaking, it is not the case at all. It is not as simple and straightforward as it seems. First, take a look at some of the problems that one may encounter while trying to start it.

No tool is perfect and foolproof. Even with lots of pros that have backed the Echo CS-400, the following are some of the problems that its users have pointed out:

  • The Saw Would Not Start. This Happens Due To:
  • Dirty air filters.
  • Bad spark plug or spark plug gap.


  • Low On Engine Oil. This May Happen Due To:
  • Clogged air filter.
  • Low on engine oil.


  • Too Much Vibration. This Usually Happens When:
  • Dull chain.
  • Damaged mufflers.
  • Lose chain.


  • Would Not Cut Properly. This Happens Due To:
  • Broken chain.
  • Low on bar oil.


  • Need A Specific Kind Of Oil For Lubrication.


  • Poor Customer Service.

Although the chainsaw might sometimes suffer from these problems, the good news is that these issues can be easily identified and fixed. Every chainsaw comes with a user manual, which is a piece of document that contains all the information about the chainsaw. It contains the saw’s description, operations, maintenance, how to start it, how to identify and fix certain issues, and much more.

Why Does The New Echo CS-400 Not Start?

When one has bought a new model, the chainsaw is brand new. now, it is obvious that its parts are clean and there is no clogging of any kind. Then why might the chainsaw not start sometimes? The possible reasons and factors have been jotted down below.

Air-Locked Fuel System

A common problem with new saws is that the pipelines are air-filled. Since the device does not have fuel in the system, the fuel lines are filled with air. The chainsaw uses a diaphragm gasket to move gas from the tank to the carburettor. Now, pulling the cord a few times can help push the gas and force the air out of the fuel lines.

This can be tested by examining the spark plug. If the spark plug is dry, then the system is air-locked. One can fix this by removing the air filter and dropping a bottle cap full of fuel mix into the carburettor intake. At this point, the chainsaw will start at the second or third pull. If the problem persists, repeat the procedure and try again.

Fuel Requirement

One needs to make sure the oil-to-gas ratio that they are using is correct. The Echo CS-400 2-stroke engine needs a 50:1 ratio of gas and oil. One can always consult the manual for further details.

Too much oil can make the mix too strong, damaging the spark plug. A damaged plug can also misfire and flood the engine. If this is the problem with the device, then we need to drain the fuel tank, refill it with the right mix, and clean the spark plug.

How To Warm-Start The Chainsaw?

If the chainsaw is being used all day long, then it is likely to be warmed up for running all day. at this point, we do not need to use the choke. It can likely flood the engine. We can rather follow the steps given here:

  • Put it on the ground.
  • Turn on the chain break.
  • Turn on the switch.
  • Hold it in place with a foot in the rear handle.
  • Start pulling the cord. It will most likely start at the first or second pull.


The Echo CS-400 is a model designed specifically for homeowners. The tool is lightweight. It is easy to keep clean as long as the instructions are followed. Like any other chainsaw, this also faces common issues with starting due to clogged filters and pipes, as well as dirty carburettors. However, these problems are easily identifiable and can be fixed.
