Assembly Steps

1. Unpack the Chainsaw

Carefully remove the chainsaw from its packaging. Check for all components: chainsaw body, guide bar, chain, and other accessories.

2. Install the Guide Bar

Locate the guide bar and chain. Place the guide bar over the mounting studs on the chainsaw. Ensure that the guide bar is oriented correctly, with the flat side facing the chainsaw body.

3. Install the Chain

Fit the chain around the guide bar, making sure the cutting edges face the right direction towards the guide bar tip. Position the chain in the groove of the guide bar.

4. Tension the Chain

With the chain in place, slide the guide bar back onto the mounting studs. Install the chain cover and secure it with the nuts, but do not fully tighten yet. Adjust the chain tension using the tensioning screw, then tighten the nuts securely.

5. Fill with Fuel

Prepare a fuel mixture of gasoline and Stihl 2-cycle oil, usually in a 50:1 ratio. Open the fuel cap and fill the tank with the mixture. Securely close the cap.

6. Fill with Bar and Chain Oil

Locate the bar and chain oil reservoir. Fill it with appropriate bar and chain oil to ensure proper lubrication.

7. Check Safety Features

Ensure the chain brake is functioning properly. Test the throttle and make sure the trigger is responsive.

8. Final Checks

Confirm all screws and bolts are tightened. Ensure there are no loose parts or tools left on the chainsaw.

Safety Precautions

Always wear protective gear, including gloves, goggles, and hearing protection. The safety of the user is paramount, and following proper safety procedures will prevent accidents and injuries.

Read the user manual for specific instructions and safety guidelines. Never attempt to start the chainsaw without proper safety gear and precautions.

Starting the Chainsaw

1. Place the chainsaw on a flat surface.

2. Engage the chain brake.
