2.1 General Chainsaw Safety

• Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, gloves, and sturdy footwear. A hard hat and leg protection are also recommended.
• Work Area: Keep the work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Children and Bystanders: Keep children and bystanders away while operating a chainsaw. Distractions can cause you to lose control.
• Weather Conditions: Do not use the chainsaw in rain or wet conditions.
• Secure Grip: Always maintain a firm grip with both hands on the chainsaw handles.
• Kickback: Be aware of kickback. Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.
• Proper Stance: Maintain proper footing and balance at all times. Do not overreach.
• Inspect Before Use: Before each use, inspect the chainsaw for damaged parts, loose components, or any other condition that may affect its safe operation.
• Battery Safety: Use only the specified battery pack and charger. Do not expose battery packs to heat or fire.

4.2 Guide Bar and Chain Installation

WARNING: Ensure the battery is removed from the chainsaw before performing any assembly or maintenance.

1. Loosen the chain tension adjustment knob (plum blossom knob) by turning it counter-clockwise and remove the side cover.
2. Carefully place the saw chain around the guide bar, ensuring the cutting edges are facing the correct direction (away from the motor at the top of the bar).
3. Fit the guide bar onto the chainsaw body, aligning the guide bar studs with the holes on the bar. Ensure the chain is seated correctly on the drive sprocket.
4. Replace the side cover and hand-tighten the chain tension adjustment knob. Do not fully tighten yet.

4.3 Chain Tension Adjustment

1. With the side cover in place but not fully tightened, use the plum blossom adjustment knob to adjust the chain tension.
2. Turn the knob clockwise to increase tension and counter-clockwise to decrease tension.
3. The chain is correctly tensioned when it can be pulled away from the guide bar by about 2-3 mm at the center, but still snaps back into place. It should move freely around the guide bar without binding.
4. Once the tension is correct, fully tighten the plum blossom adjustment knob to secure the side cover and guide bar.
5. Periodically check chain tension during operation, as it can loosen with use.

5.2 Cutting Techniques

• Assess the Cut: Before cutting, identify potential hazards such as branches under tension, obstacles, or unstable footing.
• Maintain Control: Always hold the chainsaw firmly with both hands. Keep your body balanced and avoid awkward positions.
• Start Slowly: Bring the running chain into contact with the wood gently. Do not force the saw.
• Avoid Kickback: Be extremely cautious of the guide bar tip. Avoid contact with any object, especially when cutting small, tough branches.
• Cutting Small Branches: For branches up to 190mm (7.5 inches) in diameter, make a single cut. For larger branches, consider making an undercut first to prevent pinching.
• High-Altitude Operations: For high pruning, the chainsaw can be paired with a compatible 5-meter high pole (sold separately). Ensure secure attachment and follow all safety guidelines for elevated work.

6. Maintenance

Regular maintenance ensures optimal performance and extends the life of your chainsaw. Always remove the battery before performing any maintenance.

6.1 Chain Lubrication

• The chainsaw requires manual chain lubrication. Fill the provided oil bottle with suitable chain lubricant (not included).
• Apply lubricant directly to the chain and guide bar groove before and during extended use.
• Proper lubrication reduces friction, heat, and wear on the chain and bar.

6.2 Chain Sharpening

• A sharp chain is crucial for safe and efficient cutting. Sharpen the chain regularly or have it professionally sharpened.
• Refer to the chain manufacturer's instructions for correct sharpening angles and file sizes.
• A dull chain will produce sawdust instead of chips and require more force to cut.

6.3 Guide Bar Maintenance

• Clean the guide bar groove regularly to remove sawdust and debris.
• Flip the guide bar periodically to ensure even wear on both sides.
• Check for burrs on the guide bar rails and file them smooth if present.

6.4 Cleaning and Storage

• After each use, clean the chainsaw body, guide bar, and chain with a brush or compressed air.
• Store the chainsaw in a dry, secure place, out of reach of children.
• Always install the chain guard before storing or transporting the chainsaw.
• Remove the battery from the tool when not in use for extended periods.
