Operating Instructions

Fuel Mixture

This chainsaw uses a 2-stroke engine and requires a specific fuel-oil mixture. Use the provided fuel oil mixing bottle to prepare the correct ratio (typically 25:1 or 50:1, refer to the specific ratio in your included manual). Use fresh, unleaded gasoline and high-quality 2-stroke engine oil.

Starting the Chainsaw

1. Fill Tanks: Fill the fuel tank with the correct fuel mixture and the oil tank with bar and chain oil.
2. Engage Chain Brake: Push the chain brake forward to engage it.
3. Choke: Pull the choke control lever out to the full choke position.
4. Prime (if applicable): Press the primer bulb several times until fuel is visible.
5. Start: Place the chainsaw on a flat, stable surface. Hold the front handle firmly with one hand and pull the starter cord with the other until the engine briefly fires.
6. Half Choke: Push the choke control lever halfway in.
7. Restart: Pull the starter cord again until the engine starts and runs.
8. Warm-up: Allow the engine to warm up for a few moments, then push the choke control lever fully in.
9. Disengage Chain Brake: Pull the chain brake back to disengage it before cutting.

Cutting Techniques

Always maintain a firm grip with both hands. Keep the chainsaw close to your body for better control. Plan your cuts to avoid kickback and ensure the wood is stable. For detailed cutting techniques, consult professional guides or training.

Stopping the Chainsaw

Release the throttle trigger and push the stop switch to the "OFF" position. Engage the chain brake for safety when not actively cutting.

Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your chainsaw.

• Chain Sharpening: Keep the saw chain sharp. A dull chain reduces cutting efficiency and increases kickback risk.
• Chain Lubrication: Ensure the automatic lubricating oil system is functioning correctly and the oil tank is filled with appropriate bar and chain oil.
• Air Filter Cleaning: Regularly clean or replace the air filter to maintain engine performance.
• Spark Plug Inspection: Check and clean the spark plug periodically. Replace if worn.
• General Cleaning: Clean sawdust and debris from the engine cooling fins, guide bar groove, and chain brake mechanism.
• Storage: When storing the chainsaw for extended periods, drain the fuel tank and run the engine until it stops to clear the carburetor.
