Chainsaw Safety First: Before You Begin

Before even thinking about pull starting chainsaw, safety is paramount. A chainsaw is a powerful tool, and neglecting safety measures can lead to serious injury.

Personal Protective Equipment (PPE)

• Eye Protection: Wear safety glasses or a face shield to protect against flying debris.
• Hearing Protection: Chainsaws are loud; use earplugs or earmuffs to prevent hearing damage.
• Hand Protection: Wear sturdy work gloves to improve grip and protect your hands.
• Leg Protection: Chainsaw chaps are essential to protect your legs from accidental cuts.
• Foot Protection: Wear steel-toed boots with good ankle support.
• Head Protection: A helmet can protect you from falling branches and other hazards.

Pre-Start Inspection

A thorough inspection can prevent accidents and ensure the chainsaw operates correctly.

• Chain: Check chain tension, sharpness, and lubrication. A dull or loose chain is dangerous.
• Bar: Inspect the guide bar for damage and proper lubrication.
• Controls: Ensure the throttle, chain brake, and on/off switch function correctly.
• Fuel and Oil Levels: Check and refill fuel and oil as needed. Use the correct fuel/oil mixture.
• Spark Plug: Inspect the spark plug for damage or fouling. A clean, properly gapped spark plug is vital.
• Air Filter: A clean air filter is essential for proper engine performance.
• Safety Features: Verify that the chain brake is functioning correctly.
• Surroundings: Clear the area of obstructions, including people, animals, and debris.
• Firm Footing: Ensure you have a stable and level surface to stand on. Never start a chainsaw while elevated or off-balance.

Step-by-Step: The Chainsaw Starting Guide

Here’s a detailed, step-by-step chainsaw starting guide for both cold and warm starts.

Cold Start Chainsaw Procedure

A cold start is when the engine is completely cool.

1. Activate the Chain Brake: Engage the chain brake. This prevents the chain from moving during the starting process.
2. Engage the Choke: Move the choke lever to the “on” or “full choke” position. This enriches the fuel mixture for starting a cold engine.
3. Prime the Engine: Press the primer bulb (if equipped) several times until fuel is visible.
4. Pull the Starter Cord: Place the chainsaw on the ground, holding it firmly with one hand. Use your other hand to pull the starter cord with a strong, steady motion. Don’t pull the cord all the way out. Repeat until the engine sputters or briefly starts.
5. Disengage the Choke: Move the choke lever to the “half choke” or “off” position.
6. Pull the Starter Cord Again: Continue pulling the starter cord until the engine starts and runs smoothly.
7. Release the Chain Brake: Once the engine is running smoothly, release the chain brake.

Warm Start Chainsaw Procedure

A warm start is when the engine has recently been running and is still warm.

1. Activate the Chain Brake: Engage the chain brake.
2. No Choke (Usually): Typically, a warm engine doesn’t need the choke. However, if the engine is struggling, you can use the half-choke position.
3. Pull the Starter Cord: Place the chainsaw on the ground, holding it firmly. Pull the starter cord with a strong, steady motion until the engine starts.
4. Release the Chain Brake: Once the engine is running smoothly, release the chain brake.

Alternative Starting Methods

Some chainsaws have alternative starting features:

• Decompression Valve: Some chainsaws have a decompression valve that reduces the compression in the cylinder, making it easier to pull the starter cord. Press the valve before starting.
• Electronic Ignition: Some models have electronic ignition systems that provide a more reliable spark.

Chainsaw Starting Problems: Troubleshooting

Sometimes, despite your best efforts, the chainsaw just won’t start. Here are common chainsaw starting problems and how to fix them.

Chainsaw Won’t Start Troubleshooting

Problem	Possible Cause	Solution
No Start	No Fuel	Check the fuel level and refill if necessary. Ensure the fuel is fresh and properly mixed with oil.
No Start	No Spark	Check the spark plug for damage or fouling. Clean or replace the spark plug. Ensure the spark plug wire is securely connected.
No Start	Flooded Engine	See the section below on dealing with a chainsaw flooded engine.
No Start	Clogged Air Filter	Clean or replace the air filter.
No Start	Incorrect Starting Procedure	Review the starting procedure and ensure you are following all the steps correctly.
Hard to Start	Weak Compression	This could indicate worn piston rings or cylinder damage. Consult a professional for repair.
Hard to Start	Dirty Carburetor	Clean or rebuild the carburetor. This is a more complex task and may require professional assistance.
Starts Then Stalls	Fuel/Air Mixture Issues	Adjust the carburetor settings. This should be done by a qualified technician if you are not familiar with carburetor adjustments.
Starts Then Stalls	Blocked Fuel Filter	Replace the fuel filter.
Difficult Pull Starting	Too Much Compression	If equipped, use the decompression valve.

Dealing with a Chainsaw Flooded Engine

A chainsaw flooded engine occurs when too much fuel enters the cylinder, preventing the spark plug from igniting the mixture.

1. Set the Chainsaw Down: Place the chainsaw on a flat surface.
2. Remove the Spark Plug: Carefully remove the spark plug.
3. Dry the Spark Plug: Clean and dry the spark plug thoroughly.
4. Purge the Cylinder: With the spark plug removed and the switch in the OFF position, pull the starter cord several times to purge excess fuel from the cylinder.
5. Reinstall the Spark Plug: Reinstall the spark plug, ensuring it is properly tightened.
6. Start Without Choke: Attempt to start the chainsaw without using the choke.
7. Persistence: It may take several attempts to start a flooded engine.

Chainsaw Maintenance Starting: Keeping Your Saw Ready

Regular chainsaw maintenance starting is crucial for reliable operation and longevity.

Daily Maintenance

• Clean the Air Filter: A clean air filter ensures proper airflow and engine performance.
• Check Chain Tension: Proper chain tension prevents premature wear and potential hazards.
• Sharpen the Chain: A sharp chain cuts efficiently and safely.
• Inspect the Bar: Check the guide bar for damage and proper lubrication.
• Check Fuel and Oil Levels: Refill fuel and oil as needed.

Weekly/Monthly Maintenance

• Clean the Spark Plug: Inspect and clean the spark plug regularly.
• Clean the Cylinder Fins: Remove debris from the cylinder fins to prevent overheating.
• Inspect Fuel Lines: Check fuel lines for cracks or leaks.
