7. Ensure the hand pull cannot be removed.
8. Secure the sleeve lock nut.
9. Verify complete installation before use.

2.2 Fuel Mixture

This chainsaw operates on a two-stroke engine and requires a specific gasoline-to-oil mixture. Use a 20:1 gas-to-oil ratio for the first 20 hours of break-in period. After the break-in period, use a 25:1 gas-to-oil ratio. Always use fresh, high-quality two-stroke engine oil and unleaded gasoline. A small gas can with appropriate gradations for oil fuel mixture is included to assist with accurate mixing.

2.3 Guide Bar Selection

The WOIZAO 58CC Gas Chainsaw comes with two interchangeable guide bars: an 18-inch bar for detailed work and a 20-inch bar for heavy-duty cutting tasks. Select the appropriate bar size based on the cutting requirements.

Image Description: This image illustrates the two different guide bar sizes included with the chainsaw: an 18-inch bar suitable for cutting logs up to 20 inches in diameter, and a 20-inch bar for logs up to 25 inches in diameter.

3. Operating Instructions

3.1 Cold Start Procedure

Follow these steps to start the chainsaw when the engine is cold:

Image Description: This nine-panel image provides a visual guide for starting a cold chainsaw engine. Steps include moving the chain brake lever, pulling the choke knob, turning on the ON/OFF switch, pulling the starter handle, pushing in the choke knob, rapidly pulling the starter rope, pressing and holding the throttle lockout, allowing the engine to warm up, and disengaging the chain brake.

1. Move the chain brake lever fully forward to lock the chain brake before starting.
2. Pull the choke knob out until a "click" is heard.
3. Move the ON/OFF switch to the ON position.
4. Pull the starter handle firmly and rapidly several times until the first starting sound (pops) is heard.
5. Push the choke knob in.
6. Pull the starter rope rapidly 1-4 times to start the engine.
7. Press and hold the throttle lockout. Lightly squeeze and release the throttle control to idle the engine.
8. Allow the engine to warm up for 30 seconds.
9. Carefully disengage the chain brake. The chainsaw is now ready for use.

4. Maintenance

4.1 Automatic Oiler System

The chainsaw is equipped with an automatic oil supply system that delivers a steady supply of bar and chain oil. This system ensures safe and effective use, extends the life of the chainsaw, and helps reduce fuel consumption by optimizing cutting performance. Regularly check the oil level and refill as needed with appropriate bar and chain oil.

4.2 Chain Care

Maintain the sharpness of the chain for optimal cutting performance and safety. A chain sharpening file is included with the kit. Refer to the sharpening instructions in the full manual for detailed guidance. A sharp chain is crucial for efficient cutting and to prevent kickback.

4.3 Engine Cooling

If the engine overheats during prolonged use, it may pause operation as a safety measure. In such cases, locate and press the air outlet switch to open the air outlet for cooling. Allow the engine to cool down before resuming operation.

Image Description: This diagram highlights the 'AIR OUTLET SWITCH' on the chainsaw, indicating its purpose for opening the air outlet to facilitate engine cooling when the machine overheats.

5. Troubleshooting

5.1 Engine Not Starting

If the chainsaw engine does not start, consider the following:

• Fuel Mixture: Ensure the correct gas-to-oil mixture is used and that the fuel is fresh.
• Choke Position: Verify the choke is in the correct position for starting (pulled out for cold start, pushed in after initial pops).
• ON/OFF Switch: Confirm the ON/OFF switch is in the ON position.
• Spark Plug: Check the spark plug for fouling or damage.
• Carburetor Adjustment: If the engine still does not start or runs roughly, the carburetor may require adjustment. This typically involves adjusting the Low (L) and High (H) needles. Consult a qualified service technician if you are unfamiliar with carburetor adjustments.

5.2 Engine Overheating

If the engine overheats, refer to section 4.3 Engine Cooling for instructions on using the air outlet switch. Ensure the cooling fins are clean and free of debris to allow for proper airflow.
