Replacing The Fuel Line In Your Earthquake Chainsaw

Changing the fuel line on your Earthquake chainsaw is a moderately difficult task that will take around 30-45 minutes. It is important to note that a damaged fuel line can cause your chainsaw to not start or run smoothly, so it is important to replace it if you are having these issues. Before beginning, make sure you have gathered all the necessary tools and safety equipment, including gloves, a jacket, and chaps. You will also need a manufacturer-recommended fuel line, pliers, a screwdriver, and a steel coat hanger or wire.

First, ensure your chainsaw is cold and placed on a flat surface. Then, remove the old fuel from the chainsaw and take out the cylinder cover and air filter. Next, remove the air filter housing and fuel filter. Now, take out the fuel and vent line, followed by the carburetor. With the carburetor out of the way, you can now remove the fuel line. Install the new fuel line, being careful to follow the routing of the old fuel line. Finally, close the chainsaw and test it to ensure everything is running smoothly.

Prepare your workspace

Before you begin, ensure you have a well-lit and ventilated workspace with enough room to work on your chainsaw comfortably. It is also important to ensure your chainsaw is cold before you start work. Place the chainsaw on a flat surface, preferably a waist-high table. This will help keep your back straight and prevent you from bending while working. Remember to wear safety equipment, including work gloves, safety glasses, and a jacket.

Gather the necessary tools and materials, including:

• New fuel lines (ensure they are the correct size for your chainsaw model)
• Needle-nose pliers
• A screwdriver set (both flat-head and Phillips-head)
• Scissors or wire cutters
• A steel coat hanger
• WD-40
• An old container for the old fuel
• A mobile phone (to take pictures of the arrangement of parts)

Remove the fuel

To remove the fuel from your Earthquake chainsaw, you should first place the chainsaw on a flat surface, preferably a waist-high table. This will help you maintain a straight back while working. Remember to wear protective gloves for safety.

Next, grab an old container and empty the contents of the gas tank into it. Keep this container close by, as you can use the old fuel to remove any accumulated dust or debris from the components you will be removing in the following steps.

Now, locate the fuel tank on your chainsaw. It is usually situated near the rear handle. Once you have located it, empty the fuel tank completely to avoid any spills or leaks during the rest of the process.

At this point, you should be able to identify the old fuel lines connected to the tank. There are typically two lines: one for fuel intake and another for the return. Carefully detach these fuel lines using needle-nose pliers. Be gentle to avoid damaging any other components of the chainsaw.

Finally, take note of how the old fuel lines are routed in the chainsaw. This will be important when installing the new fuel lines. You can also inspect the old lines for any signs of wear, cracks, or damage. If you notice any issues, it is recommended to replace them promptly.

Remove the cylinder cover and air filter

To remove the cylinder cover and air filter from your Earthquake chainsaw, you'll need to follow these steps:

Firstly, ensure your chainsaw is switched off and cold before beginning any maintenance work. Place the chainsaw on a flat, waist-height surface, such as a table, to ensure comfort and ease of access during the process. Remember to wear protective gloves for safety.

Next, use an appropriately-sized screwdriver to remove the nuts holding the cylinder shield in place. Craftsman models typically have three or four nuts. Once these are removed, carefully lift off the cylinder cover.

Now, you can remove the air filter. Check if it can be cleaned and replaced, or if it needs to be entirely replaced due to excessive dirt or damage. If the air filter is too dirty or worn out, it's important to replace it with a new one. Additionally, disconnect the spark plug at this stage.

By following these steps, you'll have safely removed the cylinder cover and air filter, allowing you to access other components of your Earthquake chainsaw for further maintenance or repairs. Remember to keep your workspace organised and be cautious when handling any tools or equipment.

Remove the air filter housing

To remove the air filter housing, you will need to remove the two bolts that are holding it in place. Once you have removed these bolts, carefully pull out the air filter housing and place it to one side. It is important that you keep the nuts and bolts in a safe place so that they do not get lost.

On the backside of the air filter housing, there will be a part of the throttle linkage attached. You must inspect this carefully, as you will need to attach it in the same way when you are reassembling the chainsaw. It is a good idea to take a photo of the arrangement on your phone so that you can refer back to it later.

Now that you have removed the air filter housing, you can move on to the next step of taking out the fuel filter.

Install the new fuel line

Now that you have successfully removed the old fuel line, it is time to install the new one.

Firstly, you must ensure you have a manufacturer-approved fuel line for the best performance. While a standard fuel line will work, it is always better to use company-approved components. You will also need scissors to splice one end of the fuel line. This will make it easier to feed into the hole for the fuel line. Feeding the line into the hole can be a little technical, so be careful. Once you have a hold of the line from the other side, it will be easier to pull it through.

Compare the new line with the old one to get an idea of how much pipe you need to insert into the carburetor. Ensure you have enough length on the other side to attach the fuel filter. Once the pipe has been attached to the carburetor and the primer bulb line, you can attach the fuel pipe to the fuel filter before putting it inside the fuel tank.

Now, you need to close the chainsaw. Start by placing the carburetor back in its place. Make sure it fits perfectly on the studs. Then, attach the throttle linkage on the backside of the air filter housing. The photos you took earlier will help now. Put the air filter housing back in its place and tighten the bolts. If everything is placed correctly, you won't need to force anything when fitting the housing. Now, place the air filter in its place and connect the spark plug. Finally, screw down the cylinder shield. Ensure you remove any dust, oil, or grease on the inside of the shield and air filter housing.
