5. Setup

5.1 Fuel and Chain Oil Preparation

This chainsaw requires a mixture of gasoline and 2-stroke engine oil. Always use fresh, high-quality unleaded gasoline and a premium 2-stroke engine oil specifically designed for air-cooled engines. Refer to the engine oil manufacturer's instructions for the correct mixing ratio (typically 50:1 or 25:1).

• Fuel Mixture: Mix gasoline and 2-stroke oil in a separate, approved fuel container. Shake well before filling the chainsaw's fuel tank.
• Chain Oil: Fill the chain oil tank with high-quality bar and chain oil. Do not use waste oil or motor oil, as this can damage the pump and chain.

5.2 Guide Bar and Chain Installation

1. Ensure the chain brake is disengaged.
2. Remove the chain cover by loosening the two nuts.
3. Fit the chain onto the sprocket and around the guide bar, ensuring the cutting edges face the correct direction.
4. Mount the guide bar onto the studs, aligning the chain tensioner pin with the hole in the guide bar.
5. Replace the chain cover and hand-tighten the nuts.
6. Adjust the chain tension using the tensioning screw. The chain should be snug against the bar but still able to be pulled freely by hand. Lift the tip of the guide bar slightly while tightening the nuts to ensure proper tension.
7. Fully tighten the chain cover nuts.

6. Operating Instructions

6.1 Starting the Engine (Cold Start)

1. Place the chainsaw on a firm, flat surface.
2. Engage the chain brake.
3. Press the primer bulb several times until fuel is visible in the return line.
4. Pull the choke lever to the "FULL CHOKE" position.
5. Hold the chainsaw firmly with one hand on the front handle and pull the starter rope handle briskly until the engine "pops" or attempts to start (usually 1-3 pulls).
6. Push the choke lever to the "HALF CHOKE" or "RUN" position (depending on model).
7. Pull the starter rope again until the engine starts and runs.
8. Once the engine is running, blip the throttle to disengage the choke completely.
9. Allow the engine to warm up for a few moments before disengaging the chain brake and beginning work.

6.2 Starting the Engine (Warm Start)

If the engine is warm, the choke may not be necessary. Simply pull the starter rope until the engine starts.

6.3 Cutting Operation

• Always maintain a balanced stance and firm grip.
• Plan your cuts to avoid kickback and ensure the wood is stable.
• Let the chainsaw do the work; do not force it.
• Be aware of falling branches and logs.

Release the throttle trigger and move the engine stop switch to the "OFF" position.
