Echo CS-590: Start-Up Instructions, General Problems, and Solutions
Echo CS-590 Timber Wolf is one of the most common mid-sized chainsaws, and it's a good choice for dependable, strength, and durability. However, as with all machine start-ups, if you're not accustomed to starting the equipment or if there is a problem, you could have some difficulty starting it. If you need to learn to start the Echo chainsaw CS-590, or if you are having starting issues, this guide will help you get the Echo running again and make sure it runs great thereafter.
How to Start Echo Chainsaw CS-590
If you're unfamiliar with the Echo CS-590 Timber Wolf, here's how to start it safely and correctly in a step-by-step method:
| Step | Action |
|---|---|
| Step 1 | Place the saw on a horizontal surface and engage the chain brake. |
| Step 2 | Flip the stop switch to the "ON" position. |
| Step 3 | Press the purge bulb several times |
The same guidelines apply if you are looking for the Echo Timber Wolf CS-590—only how to start—they are both the same model.

ECHO CS-590 Won't Start: Common Causes and Fixes
If your ECHO CS-590 won't start, the problem may involve the fuel supply, air intake, ignition system, or starting procedure.
Begin with simple inspections before assuming that a major component needs replacement.
Always stop the engine and allow it to cool before performing maintenance. Disconnect the spark plug lead when instructed by the service procedure, and keep the saw away from ignition sources when handling fuel.
Old Fuel or Incorrect Fuel Mixture
The ECHO CS-590 uses a two-stroke engine that requires gasoline mixed with approved two-stroke engine oil.
For current ECHO documentation, the specified mixture is generally 50:1 when using ECHO-approved two-stroke oil, although you should verify the requirements in the manual for your exact unit.
Old fuel, contaminated gasoline, or an incorrect oil mixture can contribute to hard starting, poor combustion, and engine performance problems.
What to check:
- Confirm that the fuel was mixed according to the operator's manual.
- Check for stale fuel or signs of contamination.
- Inspect the fuel tank and cap for visible problems.
- Use fresh, correctly prepared fuel when necessary.
Never operate the chainsaw on straight gasoline without the required two-stroke oil.
Dirty or Clogged Air Filter
The air filter helps prevent dust, sawdust, and other debris from entering the engine.
When the filter becomes clogged, restricted airflow can affect combustion and make starting or running the engine more difficult.
What to check:
- Remove and inspect the air filter according to the operator's manual.
- Look for heavy dirt buildup, damage, or deterioration.
- Clean or replace the filter using the manufacturer's recommended procedure.
- Reinstall the filter correctly before operating the chainsaw.
Avoid running the engine without the air filter installed.
Faulty or Fouled Spark Plug
The spark plug ignites the fuel-air mixture inside the engine.
A worn, damaged, or fouled spark plug may contribute to difficult starting, misfiring, or inconsistent engine operation.
What to check:
- Inspect the spark plug for visible damage or heavy deposits.
- Confirm that the plug is the correct type for your CS-590.
- Check the electrode gap against the specifications in your operator's manual.
- Replace the spark plug if it is damaged or no longer serviceable.
Spark plug condition is only one part of the ignition system. If the problem continues, additional diagnosis may be required.
Flooded ECHO CS-590 Engine
An engine can become flooded when excessive fuel enters the combustion chamber during repeated starting attempts.
This may happen when the choke remains engaged after the engine has already fired or when the cold-start procedure is repeated unnecessarily.
Common signs include:
- The engine briefly fires but does not continue running.
- Repeated starter pulls do not produce a successful start.
- A strong fuel odor is present near the engine.
What to do:
Stop attempting to start the engine and review the flooded-engine procedure in your CS-590 operator's manual.
Follow the manufacturer's instructions for clearing excess fuel. Do not improvise procedures involving exposed ignition components or spilled gasoline.
If flooding continues after using the correct starting procedure, inspect the fuel delivery system or seek assistance from an authorized service technician.
Carburetor and Fuel Delivery Problems
The carburetor regulates the fuel-air mixture entering the engine.
Problems with fuel delivery can cause hard starting, rough idling, poor acceleration, or an engine that stalls during operation.
Potential causes include:
- Restricted fuel filters
- Damaged or blocked fuel lines
- Contaminated fuel
- Carburetor deposits or internal wear
- Incorrect carburetor settings
Start by inspecting accessible fuel system components according to the operator's manual.
Carburetor adjustments and internal repairs may require specialized tools and service knowledge. If the problem persists, contact an authorized ECHO service dealer rather than making unverified adjustments.
Other ECHO CS-590 Starting Problems
Not every starting problem has the same cause. Paying attention to when and how the engine fails can help narrow down the components that need inspection.
ECHO CS-590 Starts Then Dies
If your ECHO CS-590 starts but stalls shortly afterward, check whether the engine is receiving a consistent fuel supply and adequate airflow.
Possible areas to inspect include the air filter, fuel filter, fuel lines, and carburetor.
Also confirm that the starting controls have been returned to their correct operating positions.
If the engine repeatedly stalls or the chain moves while the engine is idling, stop using the chainsaw and have it inspected.
ECHO CS-590 Is Hard to Start
A chainsaw that requires repeated starter pulls may have a starting procedure issue or a maintenance-related problem.
Begin by checking the fuel mixture, engine temperature, choke position, and stop switch.
Next, inspect the air filter and spark plug.
If these checks do not identify the cause, additional fuel system or ignition system diagnosis may be necessary.
ECHO CS-590 Won't Start After Sitting
A chainsaw that has been stored for an extended period may develop starting problems related to fuel deterioration or maintenance needs.
Before attempting to restart equipment after storage:
- Inspect the fuel tank and fuel condition.
- Check the air filter and spark plug.
- Examine fuel lines for visible damage.
- Inspect the guide bar, chain, and chain brake.
- Follow the manufacturer's instructions for returning stored equipment to service.
Avoid using the chainsaw if you find fuel leaks, damaged safety components, or other conditions that could make operation unsafe.
ECHO CS-590 Maintenance Tips to Prevent Starting Problems
Routine maintenance can help reduce preventable starting problems and support reliable operation.
Follow the service intervals and procedures provided in the ECHO CS-590 operator's manual.
Check the Fuel, Air Filter, and Spark Plug
Before using your chainsaw, inspect the equipment for visible damage and check that the fuel and chain oil levels are appropriate.
As part of regular maintenance:
- Use the recommended fuel and two-stroke oil mixture.
- Inspect and service the air filter as directed.
- Check the spark plug according to the maintenance schedule.
- Inspect fuel lines and filters for deterioration.
- Keep cooling passages and accessible exterior surfaces free of excessive debris.
The correct maintenance intervals depend on operating conditions and the manufacturer's recommendations.
Follow Proper Chainsaw Storage Practices
Proper storage can help reduce fuel-related problems and equipment deterioration.
Clean the exterior of the chainsaw after use and inspect the guide bar and chain.
For extended storage, follow ECHO's fuel system preparation instructions rather than leaving untreated fuel in the equipment indefinitely.
Store the chainsaw in a dry, secure location, away from children and unauthorized users.
Keep the chain covered with an appropriate guide bar scabbard when the equipment is not in use.
ECHO CS-590 Replacement Parts for Starting Problems
If troubleshooting reveals a damaged or worn component, replacing the correct part may help restore normal operation.
Depending on the diagnosis, commonly inspected components include:
- Spark plugs: Used in the ignition system to ignite the fuel-air mixture.
- Air filters: Help protect the engine from airborne debris.
- Fuel filters: Help prevent contaminants from reaching the fuel system.
- Fuel lines: Carry fuel between the tank and engine components.
- Carburetors and related parts: Regulate fuel delivery and mixture.
- Recoil starter components: Support the manual engine-starting mechanism.
