Echo CS 590 Starting Problems and Solutions

You can buy an Echo CS 590 and it can give good service for a number of years. However, if you’ve been using it for a long time, it can show some problems. One of the most common issues is that your Echo CS 590 will not turn on.

So let’s find out what might cause these problems. 

Reason 1: Defective Spark-plug

It’s possible that the spark plug is faulty. This can later lead to your chainsaw not starting properly.

Solution

Disconnect the spark plug and check it for any damage. Examine If your porcelain insulator is breaking, it’s time to replace it. This means that one electrode has been broken or worn away. It can also mean that the electrode has a significant amount of carbon accumulation.

Simply replace the spark plug to correct the problem. However, you should change the spark plug even if it hasn’t been changed in a few years.

Reason 2: Clogged Carburetor

It’s possible that the carburetor is clogged. Keeping fuel in the chainsaw for an extended amount of time can clog the carburetor.

Some of the components in the gasoline will vaporize over time. This results in a thicker and sticky residue. This mushy fuel could clog the carburetor, making the engine unable to start.

Solution

If the carburetor is clogged, clean it with a carburetor cleaner. Cleaning the carburetor isn’t always beneficial if it’s severely damaged. You’ll need to repair or replace the carburetor in this situation.

Reason 3: Damaged Ignition Coil

A faulty ignition coil transfers power to the spark plug while the engine is operating. If the ignition coil fails, the engine may not start.

Solution

When changing the ignition coil, make sure the spark plug is in proper working order. Use an ignition coil tester if you’re certain the spark plug isn’t defective. This device will help you to check the ignition coil. Lastly, replace the ignition coil if it’s damaged.

Reason 4: Defective Recoil Starter

The recoil starter assembly connects the crankshaft to turn the engine over. If the recoil initiating unit fails, the engine would not start. The chainsaw would not start as an outcome. 

Solution

To check your recoil starter, you must first remove the starting assembly. Then you must examine it to determine if it is in good working order.

Ensure the tabs protruding from the pulley are tightly screwed to the engine hub. Check this while pulling the starting rope.

The engine will turn as a result of this. The tabs should shrink. And the rope should unwind back on the pulley when you loosen the rope. Replace the recoil starter assembly if it isn’t working correctly.

Reason 5: Broken Rewind Spring

When the starter rope is pulled and released, the rewind spring pulls back it onto a pulley. If the rewind spring is destroyed, the rope will not be able to return to the chainsaw pulley. As a consequence, restarting the car may be difficult or impossible.

Solution

Reinstall the rewind spring if it is damaged. Manually, many rewind springs can be replaced. It may, however, It’s much simpler to replace the entire recoil starter unit.

Reason 6: Broken Spark Arrestor

The spark arrestor is a tiny screen that stops sparks from being produced by the engine. The spark arrestor might become blocked with dirt over time. The chainsaw may stop or run harshly if the spark arrestor is jammed. 

Solution

Just take the spark arrestor out and clean it with a soft brush to clear it. The spark arrestor can be replaced too. But only if the mesh is damaged. 

Reason 7: Clogged Air Filter

It’s conceivable that your air filter is dirty or blocked. The engine will receive excessive fuel and not enough air if the air filter is jammed. The engine may stop or run roughly as a consequence. 

Solution

Examine the air filter to see if it’s jammed. You must first clean the air filter with a brush if it is blocked. If a cleanup doesn’t work, you’ll have to replace it.

Reason 8: Worn Out Clutch Pads

To enable the chain to revolve, the clutch pads connect the clutch drum. The motor will operate if the clutch pads are burned out. However, the clutch pads will not connect to the clutch drum. As a consequence, the chain is unable to rotate. 

Solution

To begin, ensure that the stop lever is not engaged. The chain will not turn if the stop lever is locked. Reinstall the clutch assembly if the clutch pads are burned out.

Take the top cover of the engine casing off to access the carburetor. And take the top of the cylinder head before cleaning your chainsaw. This allows you to reach the air filter as well as the spark plug.
