What You'll Learn
Wear protective gear
Electric chainsaws are powerful tools, and safety should always be the top priority when working with them. Before attempting to replace the chain, it is important to wear protective gear to shield yourself from potential hazards. Here are the key items you should consider:
Eye and Face Protection: Safety glasses or goggles are essential to protect your eyes from flying wood chips and debris. These particles can cause serious eye damage and even vision loss. Some people prefer using a visor, which provides ventilation in hot weather, while others opt for safety goggles to prevent smaller pieces of debris from entering the eyes. Face shields offer additional protection by guarding your face against projectiles and falling branches.
Hearing Protection: Chainsaws can be incredibly loud, and prolonged exposure to high noise levels can lead to permanent hearing damage. Wear ear defenders, ear plugs, or earmuffs to attenuate the noise to safe levels.
Head Protection: A chainsaw helmet is crucial for protecting your head from falling limbs, branches, and other projectiles. It is designed to withstand impacts and shield you from potential head injuries.
Leg Protection: Leg protection is vital when operating a chainsaw. You can choose between chainsaw chaps and protective chainsaw pants. Chaps are easier to put on and take off, making them ideal for quick tasks or occasional use. They protect your legs by jamming the flywheel, reducing the likelihood of deep cuts. However, they may not cover the entire rear calf region, leaving parts of your legs exposed. Protective chainsaw pants, on the other hand, are designed for all-day use and provide full leg coverage. They comply with safety standards and are made of materials that slow down the chain's cutting rate, giving you time to react.
Footwear: Chainsaw boots are a type of steel-toe boot with added layers of protective fabric on the exposed front surfaces. They safeguard your feet from potential chainsaw contact and falling objects.
Hand Protection: Chainsaw gloves are specifically designed to protect your hands, especially the back of your left hand, which is the most common area for chainsaw injuries. Gloves with Velcro wrist straps can provide both protection and a secure fit.
Remember, your safety is paramount when working with electric chainsaws. Always follow safety precautions and wear the appropriate protective gear to minimize the risk of injuries.

Loosen the tensioning screw
To loosen the tensioning screw on an electric chainsaw, follow these steps:
Firstly, it is important to ensure you are wearing protective gear, including safety glasses, hearing protection, gloves, and a full-face shield. This is because electric chainsaws are powerful tools, and your safety should be the top priority when making any adjustments.
Next, locate the tensioning screw. This is usually found on the inside or side of the guide bar. The tension adjustment screw is used to adjust the tension of the chainsaw chain. By tightening the screw, the chain is tightened, and by loosening the screw, the chain is loosened.
Once located, use a screwdriver or wrench to loosen the tensioning screw. Turn the screw counterclockwise to loosen it. Be careful not to overtighten or over-loosen the screw, as this can affect the performance of your chainsaw. A properly tensioned chainsaw chain should be a little loose on the guide bar, but tight enough that the drive links do not come out.
After loosening the tensioning screw, you can proceed with installing the new chain. Carefully thread the new chain around the clutch drum, ensuring the drive links engage in the sprocket. With the chain properly threaded, you can then adjust the tension to the correct level by pulling on the nose of the guide bar.
It is important to note that different models of electric chainsaws may have slightly different designs and tensioning mechanisms. Always refer to your chainsaw's user manual for specific instructions and safety precautions.

Thread the new chain
Threading a new chain onto your electric chainsaw is a fundamental skill for chainsaw owners. Before starting, ensure you are wearing protective gear, including safety glasses, hearing protection, gloves, and a full-face shield. Additionally, clear a safe workspace, laying down cardboard or newspaper, and ensure your workspace is well-lit.
First, loosen the tensioning screw on the inside of the guide bar. This will make installing the new chain easier. Next, carefully thread the new chain around the clutch drum, ensuring that the drive links engage with the sprocket. Thread the rest of the drive links into the guide bar and around its nose. Ensure the chain is facing the right direction; the teeth should be facing away from you while you are holding the chainsaw.
With the chain properly threaded, pull on the nose of the guide bar away from the chainsaw to create some tension. While doing this, ensure that the guide bar is seated onto the saw's adjustment pin. The side plate is ready to be replaced once the guide bar is correctly positioned.
Finally, replace the side plate and the nuts that hold it in position, but do not tighten them all the way yet. Allow the guide bar to move slightly as you tighten the chain to the correct tension. Once the chain is properly tensioned, you can fully tighten the nuts on the side plate.

Adjust the tension
Adjusting the tension on your electric chainsaw is critical for performance and safety. A loose chain can slip and bounce, reducing cutting efficiency and increasing the risk of kickback. Over-tightening the chain can also cause issues, such as increased friction, premature wear, and binding in the bar groove, which may cause the engine to stall or the chain to jerk uncontrollably. Therefore, it is essential to achieve the proper tension for your saw.
To adjust the tension on your electric chainsaw, first, ensure the chainsaw is unplugged and turned off, with the ignition switch disconnected. Put on safety gloves and slightly lift the nose of the bar. Next, locate the tensioning screw or knob. This is usually perpendicular to the direction of the chain and may be found between the mounting studs, on the outside of the chainsaw, or on the bar cover or engine.
Once located, use a screwdriver or scrench (a screw/wrench combo) to tighten the screw in small, clockwise increments. As you tighten, continue to lift the nose of the bar slightly. The goal is to achieve minimal slack in the chain, with the chain feeling snug but still pulling freely. Check the tension after each turn of the screw and ensure the chain can still move freely around the guide bar.
Finally, perform a ""snap" test to ensure proper tension. Pull the chain on the underside of the guide bar down so that one or two drive links are out of the guide bar rails, then release it. The chain should snap directly into position. If the chain passes the snap test, reattach the cover and tighten the nuts or screws to secure the bar in place.

Test the chain
Testing the tension of the chain is a crucial step in ensuring your chainsaw is running optimally and safely. Here is a detailed guide on how to test the chain tension:
Firstly, locate the chain tension adjustment points on your chainsaw. These are commonly found on the side cover or the front of the chainsaw. With the chainsaw turned off and the cover removed, you can visually inspect the tension. Gently pull the chain away from the guide bar to check if the links remain engaged. The links should want to lift up slightly but not enough to become dislodged. This test will help you determine if the chain is too loose. A properly tensioned chain will move smoothly with little force.
The "Snap" Test:
Hold the nose of the bar and perform a "snap" test to ensure proper chain tension. With a gloved hand, pull the chainsaw chain along the top of the guide bar from the engine to the guide bar nose several times. The chain should feel snug but still pull freely.
Adjustments:
If the chain is too loose, tighten the tension by turning the adjustment screw clockwise. Conversely, if the chain is too tight, loosen it by turning the screw counterclockwise. Always ensure that the chain is cool before making any tension adjustments.
Final Checks:
After making the necessary adjustments, it is important to perform final checks before using your chainsaw. Double-check that all components are securely fastened and the chain tension is optimal. Test run the chainsaw to ensure it runs smoothly. Regularly check the chain tension throughout your project to maintain the performance and safety of your chainsaw.
