2.1 General Safety Rules

• Always wear appropriate personal protective equipment (PPE) including a helmet, eye protection, hearing protection, heavy-duty gloves, safety boots, and leg protection (chaps).
• Never operate the chainsaw when fatigued, under the influence of alcohol, drugs, or medication.
• Keep children, bystanders, and animals at least 50 feet (15 meters) away from the work area.

• Always hold the chainsaw firmly with both hands, with your thumbs and fingers encircling the handles.
• Be aware of kickback. Avoid the guide bar tip contacting any object.
• Never cut above shoulder height.
• Ensure proper footing and balance before and during cutting.

2.2 Fuel Safety

• Mix fuel and oil in a well-ventilated area, away from sparks or open flames.
• Use a 2-stroke engine oil specifically designed for air-cooled engines. Refer to the specifications for the correct fuel-to-oil mixing ratio (e.g., 25:1 or 50:1, typically specified by manufacturer).
• Do not smoke while refueling.
• Wipe up any spilled fuel immediately.
• Allow the engine to cool before refueling.
• Store fuel in approved containers in a cool, well-ventilated area.

4. Setup and Assembly

Follow these steps to assemble your chainsaw before first use. Ensure the engine is off and cool before beginning assembly.

1. Install the Guide Plate: Remove the side cover. Position the guide plate onto the mounting studs.
2. Install the Chain: Carefully place the saw chain around the drive sprocket and into the groove of the guide bar. Ensure the cutting edges of the chain are facing the correct direction (refer to chain markings).
3. Align and Secure the Side Cover: Align the holes of the side cover with the mounting studs and the chain tensioner pin. Screw on the nut loosely.
4. Adjust Chain Tightness: Using the chain tensioning screw, adjust the chain until it is snug but can still be pulled freely around the guide bar by hand. There should be no slack on the underside of the guide bar, and the chain should not sag. Tighten the side cover nuts securely.
5. Fill Fuel and Oil Tanks:
   • Fuel: Mix gasoline with 2-stroke engine oil at the specified ratio (e.g., 25:1 or 50:1, check product specifications or included manual). Fill the fuel tank (0.15 Gallons capacity) with the mixed fuel.
   • Chain Oil: Fill the chain oil tank with appropriate bar and chain lubricant. The automatic lubrication system requires this oil for proper chain operation and longevity.

5. Operating Instructions

5.1 Starting the Chainsaw

1. Place the chainsaw on a firm, flat surface.
2. Engage the chain brake by pushing the brake baffle forward.
3. Press the primer bulb several times until fuel is visible.
4. Pull out the choke knob (if the engine is cold).
5. Hold the chainsaw firmly with one hand on the front handle and place your foot on the rear handle.
6. Pull the starter cord (manual start handle) briskly until the engine fires (usually a few pulls).
7. Push the choke knob in halfway or fully (if the engine is warm).
8. Pull the starter cord again until the engine starts and runs smoothly.
9. Allow the engine to warm up for a few moments.
10. Disengage the chain brake by pulling the brake baffle back towards the front handle.

5.2 Cutting Techniques

• Always maintain a firm grip with both hands.
• Plan your cut before starting. Identify potential kickback zones and escape routes.
• Start cutting with the chain at full speed.
• Avoid cutting with the tip of the guide bar to prevent kickback.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your chainsaw. Always turn off the engine, engage the chain brake, and disconnect the spark plug wire before performing any maintenance.

6.1 Daily Maintenance

• Clean the Air Filter: Remove and clean the air filter to ensure proper engine performance and prevent wear.
• Check Chain Tension: Adjust if necessary. A properly tensioned chain should be snug but still able to be pulled freely by hand.
• Check Chain Sharpness: A dull chain will not cut efficiently and can cause kickback. Sharpen or replace the chain as needed.
• Inspect Guide Bar: Check for wear, burrs, or damage. Clean the guide bar groove.
• Check Oil and Fuel Levels: Refill as needed.

6.2 Periodic Maintenance

• Spark Plug: Inspect and clean the spark plug. Replace if worn or fouled.
• Cooling Fins: Clean dirt and debris from the engine's cooling fins to prevent overheating.
• Fuel Filter: Inspect and replace the fuel filter periodically.
• Chain Sprocket: Inspect for wear and replace if necessary.
