How to Remove the Small Wheel on an Electric Chainsaw214

Electric chainsaws are versatile tools that can be used for a variety of tasks, from cutting firewood to trimming branches. However, like any tool, they require occasional maintenance to keep them running smoothly. One common maintenance task is replacing the small wheel, which is located at the front of the saw and helps to guide the chain. If the small wheel is damaged or worn out, it can cause the chain to derail, which can be dangerous. Fortunately, replacing the small wheel is a relatively simple task that can be completed in a few minutes.

Tools You Will Need
Phillips head screwdriver
Flat head screwdriver
Needle-nose pliers
New small wheel

Step-by-Step Instructions

1. Unplug the chainsaw from the power source. This is a critical safety precaution that should always be taken before performing any maintenance on an electric chainsaw.

2. Remove the chain guard. The chain guard is typically held in place by a few screws. Remove the screws and set the chain guard aside.

3. Loosen the chain tensioner. The chain tensioner is located at the rear of the saw. Use a flat head screwdriver to loosen the tensioner knob.

4. Remove the chain. Grip the chain with a pair of needle-nose pliers and pull it off the sprocket. Set the chain aside.

5. Remove the small wheel. The small wheel is held in place by a Phillips head screw. Remove the screw and pull the small wheel off the shaft.

6. Install the new small wheel. Slide the new small wheel onto the shaft and tighten the Phillips head screw. Make sure the small wheel is seated properly on the shaft.

7. Reinstall the chain. Place the chain on the sprocket and pull it through the guide bar. Adjust the chain tensioner until the chain is snug but not too tight.

8. Reinstall the chain guard. Replace the chain guard and tighten the screws.

9. Plug the chainsaw into the power source. The chainsaw is now ready to use.

Tips
If you are not comfortable replacing the small wheel yourself, you can take the chainsaw to a qualified repair shop.
When replacing the small wheel, it is important to use the correct size wheel. Using a wheel that is too small or too large can cause the chain to derail.
It is a good idea to replace the small wheel regularly, even if it does not appear to be damaged. This will help to prevent the chain from derailing.
