How to Start a Gas Chainsaw?

Starting a gas chainsaw can be intimidating, but it’s a straightforward process once you understand the steps.

Step-by-Step Guide 

Starting a cold engine on a chainsaw requires a slightly different approach than starting a warm engine. Here are some tips for starting a cold engine on a chainsaw:

Check the Fuel

The chainsaw’s fuel tank is typically located on the side or top of the engine housing. To check the fuel level, remove the fuel cap and look inside the tank. If the fuel level is low, add fresh gasoline to the tank.

Proper fuel and oil levels are critical for a chainsaw’s safe and efficient operation. Always check the levels before every use and top them up as needed. 

Locate the chain brake: The chain brake is typically located on the top handle of the chainsaw. It can be activated by pushing the front hand guard forward or pulling the chain brake lever back.

Engage the chain brake: Engage the chain brake to prevent the chain from spinning. Engaging the chain brake is a crucial safety step before starting a chainsaw. 

Check the Fuel

Engage the chain brake: To engage the chain brake, push the front-hand guard forward or pull the chain brake lever back. This will cause the brake band to tighten around the clutch drum and stop the chain from rotating.

Test the chain brake: Once the chain brake is engaged, test it by trying to rotate the chain manually. The chain should not move.

Engaging the chain brake is essential for preventing accidental injuries from the chainsaw chain. Always engage the chain brake before starting the chainsaw; never release it until you are ready to use it.

Inspecting the chain brake regularly for wear and tear and replacing damaged components is also essential. 


Set the Controls

 Setting the controls on a chainsaw is essential in preparing the saw. The controls on a chainsaw include the throttle control and the choke control. 

  1. Locate the controls: The controls on a chainsaw are typically located on the top or rear handle of the saw.
  1. Throttle control: The throttle control regulates the speed of the chainsaw’s engine. Move the throttle trigger to the “fast” or “run” position to set the throttle control.
  1. Choke control: The choke control is used to help start the chainsaw’s engine. To set the choke control, move it to the “full” or “closed” position. This will restrict airflow to the engine and increase the fuel-to-air ratio, making it easier to start the engine.
  1. Other controls: Some chainsaws may have other controls, such as a decompression valve or a primer bulb. Consult the chainsaw’s manual for specific instructions on how to set these controls.

Correctly setting the controls on a chainsaw can make starting and operating the saw much more accessible. Always consult the chainsaw’s manual for specific instructions on how to set the controls, as the location and function of the controls may vary between different models of chainsaws.

Prime the Engine

 Priming the engine is essential in starting a chainsaw, especially when starting a cold engine. Priming helps to create a fuel-air mixture in the carburetor and makes it easier to start the engine. 

Prime the Engine
  1. Locate the primer bulb: The primer bulb is typically located on the side of the chainsaw’s carburetor. It’s usually a small, black rubber bulb.
  2. Press the primer bulb: Press the primer bulb several times, depending on the recommendations in the chainsaw’s manual. This will force fuel from the fuel tank into the carburetor and create a fuel-air mixture.
  3. Check for fuel: Check the primer bulb for fuel after priming the engine. If you see fuel in the bulb, the engine is properly primed and ready to start.
  4. Do not over-prime: Avoid over-priming the engine, as this can flood the engine and make it more challenging to start.

Primarily the engine before starting the chainsaw can help to ensure that the engine starts quickly and runs smoothly. Always follow the manufacturer’s instructions for priming the engine, as the number of times to press the primer bulb may vary between different models of chainsaws. 

Pull the Starter Cord

 Pulling the starter cord is the next step in starting a chainsaw. The starter cord rotates the engine and ignites the fuel-air mixture, causing the engine to start. 

  1. Hold the chainsaw correctly: Hold the chainsaw firmly with both hands. Keep the chainsaw on a flat surface and make sure the chain brake is engaged.
  2. Locate the starter cord: The starter cord is typically on the side of the chainsaw’s engine housing. It’s usually a bright-colored cord.
  3. Pull the starter cord: Grasp the starter handle firmly and pull the starter cord in a smooth, steady motion. 
  4. Release the starter cord slowly to prevent it from snapping back and injuring you.
  5. Repeat if necessary: If the engine doesn’t start on the first try, repeat the process of priming the engine and pulling the starter cord until the engine starts.

Pulling the starter cord can be difficult, especially if the engine is cold or the chainsaw is new. Make sure to use a smooth, steady motion when pulling the cord, and don’t yank it too hard or fast. With practice, you can start the chainsaw engine quickly and safely.

Let the engine Warm-Up

 Once the engine starts, it must warm up before using the chainsaw. Letting the engine warm up helps to ensure that the chainsaw runs smoothly and reduces the risk of damage to the engine. 

  1. Disengage the chain brake: Disengage the chain brake by pushing the front-hand guard forward or pulling the chain brake lever back.
  2. Allow the engine to idle: Let the engine idle for a few seconds after starting. The idle speed should be set according to the manufacturer’s recommendations in the chainsaw’s manual.
  3. Adjust the choke: Move the choke control to the “half” or “open” position to let in more air and prevent the engine from flooding.
  4. Monitor the engine: Monitor the engine while it’s warming up to ensure it’s running smoothly and doesn’t stall. If the engine stalls, you may need to repeat the process of priming the engine and pulling the starter cord.
  5. Warm-up time: Let the engine warm up for a few minutes or until the engine runs smoothly and the chainsaw is ready.

Letting the engine warm-up is an essential step in starting a chainsaw. It helps to ensure that the chainsaw runs smoothly and reduces the risk of damage to the engine. 

Disengage the Choke

Disengaging the choke is the next step after letting the chainsaw engine warm up. The choke is used to help start the engine by restricting airflow to the carburetor, creating a richer fuel-air mixture.

Disengage the Choke
  1. Locate the choke control: The choke control is typically on the side of the chainsaw’s carburetor. It may be a lever or a button.
  2. Move the choke control: Move the choke control to the “half” or “open” position. 
  3. Monitor the engine: Monitor the engine while disengaging the choke to ensure it’s running smoothly and doesn’t stall. If the engine stalls, you may need to engage the choke again or repeat the process of priming the engine and pulling the starter cord.
  4. Adjust the throttle: Adjust the throttle control to the desired speed using the trigger. Squeeze the trigger gently to increase or release it to decrease the speed.

How to Start an Electric Chainsaw?

Starting an electric chainsaw is much easier than starting a gas-powered chainsaw, and it’s a quieter and more environmentally-friendly option.

  1. Check the power supply: Ensure the chainsaw is plugged in and the power source works correctly.
  2. Engage the chain brake: Engage the chain brake to prevent the chain from rotating while starting the chainsaw.
  3. Press the safety trigger: Press the safety trigger and hold it down while you start the chainsaw. The safety trigger is typically located on the rear handle of the chainsaw.
  4. Disengage the chain brake: Disengage the chain brake once the chainsaw runs smoothly.
