3. Setup

Assembly:

Follow these steps to properly assemble the guide bar and chain onto your chainsaw:

1. Open the Side Cover: Locate and open the side cover of the chainsaw.
2. Install Inverted Plate: Position and install the inverted plate correctly.
3. Install Saw Chain: Carefully install the saw chain onto the guide bar, paying close attention to the direction of the cutting teeth.
4. Adjust Chain Tightness: Close the side cover partially and adjust the chain tightness. The chain should be snug but still able to be pulled freely by hand, with approximately 0.4-0.6 inches of play.
5. Lock Side Cover: Securely lock the side cover in place.
6. Installation Complete: Ensure all components are firmly attached and the chain moves smoothly.

Fuel and Oil Mixture:

This chainsaw operates on a 2-cycle engine and requires a specific fuel-to-oil mixture. Use unleaded gasoline mixed with 2-cycle engine oil at a ratio of 25:1 (Gasoline:Two-Cycle Oil). Always use a fresh fuel mixture. Do not use E85 fuel or any fuel containing more than 10% ethanol.

For the chain and bar lubrication, use a high-quality bar and chain oil. Do not use waste oil or motor oil not specifically designed for chainsaw bars and chains.

4. Operating Instructions

Starting the Chainsaw:

Follow these steps for a quick and easy start:

1. Ensure Switch is ON: Verify the ON/OFF switch is in the 'ON' position.
2. Pull Switch Up: Pull the switch lever upwards.
3. Engage Choke Knob: Pull out the choke knob to engage the choke.
4. Pull Start Handle: Pull the start handle quickly several times until the engine briefly fires or 'pops'.
5. Push Choke Knob In: Once you hear the engine 'pop', push the choke knob back in.
6. Pull Start Handle Again: Pull the start handle quickly again several times until the engine starts.
7. Press Throttle Interlock and Trigger: Once the engine is running, press the throttle interlock and then the trigger to disengage the high idle.
8. To Stop: Pull the switch to the 'STOP' position to turn off the machine.

Cutting Techniques:

Always plan your cut before starting. Ensure stable footing and a clear escape path. Avoid cutting with the tip of the guide bar to prevent kickback. When cutting, let the saw do the work; do not force it. Maintain a balanced stance and keep both hands firmly on the handles.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your chainsaw.

Air Filter System:

The chainsaw is equipped with a quick-release air filter system. Regularly inspect and clean the air filter to prevent dust and debris from entering the engine. A clean air filter ensures optimal engine performance and extends engine life. The sprocket's internal structure also features a three-tier gasoline filter for additional protection.

Automatic Oiling System:

The chainsaw features an automatic oiling system that continuously supplies bar and chain oil during operation. This ensures stable lubrication, reduces friction, and prolongs the service life of both the chain and the guide bar. Always ensure the oil tank is filled with appropriate bar and chain oil before use.

General Maintenance Tips:

• Chain Sharpening: Keep the chain sharp for efficient and safe cutting. A dull chain can cause the saw to jump and increase the risk of kickback.
• Guide Bar Maintenance: Clean the guide bar groove and oil holes regularly. Flip the guide bar periodically to ensure even wear.
• Spark Plug: Inspect and clean the spark plug periodically. Replace if worn or fouled.
• Cleaning: After each use, clean the chainsaw thoroughly, removing sawdust and debris from the engine fins, air filter cover, and chain brake mechanism.
