- 1). Pull back the brake lever so that it is facing the hand guard. The chain brake is toward the front of the chainsaw between the guide and the front handle. Pull the spark plug wire off the spark plug with your fingers. Make sure you're wearing heavy work gloves to protect your hands.
- 2). Remove the two nuts that secure the left side of the chainsaw body to the chainsaw with the multi-purpose tool that comes with the chainsaw. If you cannot find your multi-purpose tool, use an appropriate-size socket wrench. Remove the left side of the chainsaw body and the holding plate that is over the chain guide bar.
- 3). Grasp the chain guide bar with your hands and pull the guide bar toward you to pull the bar of the two bar bolts near the main body of the chainsaw. Slip the chain over the sprocket and remove the chain from the guide bar.
- 4). Spread the new chain in a loop in front of the chain saw with the cutting edges pointing in a clockwise direction. Slide the chain over the sprocket on the chainsaw behind the clutch. Ensure that the sprocket teeth fit inside the chain.
- 5). Slide the chain guide bar back into position with the adjusting slot over the two securing bolts. There is also an adjusting slot on the guide bar below the two bolts that fits over an adjusting tab on the chainsaw.
- 6). Starting from the top closest to the chainsaw, guide the chain over the edge of the guide bar.
- 7). Turn the clutch that is over the chain sprocket clockwise by hand to aid setting the chain completely around the chain guide bar. Place the holding plate over the chain guide bar with the flanges pointing away from the chain.
- 8). Place the chainsaw body cover back over the chainsaw and thread the retaining nuts over the bolts until hand tight.
- 9). Locate the adjustment screw on the front of the chainsaw near the chain guide bar. Hold the front of the chain guide bar up and turn the adjustment screw with a flat head screwdriver to tighten the chain.

Keep the nose of the chain bar guide up while you tighten the two cover retaining nuts with the multi-purpose tool or socket wrench. - 11
When installing the chain bar guide, it should be flush against the inside of the chainsaw body. If it is not, it is usually because the adjusting tab is not inserted through the hole on the chain bar guide.
