• Work Area: Ensure the work area is clear of bystanders, pets, and obstacles. Maintain a safe distance from others.
• Inspect Chainsaw: Before each use, check the chainsaw for loose parts, damage, or proper chain tension. Ensure the chain brake functions correctly.
• Fuel/Battery Safety: For battery-powered chainsaws, ensure the battery is fully charged and properly inserted. Never operate with a damaged battery or charger.
• Proper Grip: Always hold the chainsaw firmly with both hands, with your thumbs and fingers encircling the handles.
• Avoid Kickback: Be aware of the kickback danger zone at the tip of the guide bar. Avoid cutting with this area.

4. Setup

4.1 Battery Installation and Charging

The chainsaw operates on a 40V Lithium-Ion battery. Ensure the battery is fully charged before first use.

1. To charge the battery, connect the charger to a standard power outlet.
2. Slide the 40V Lithium-Ion battery into the charger until it clicks into place. The charger indicator lights will show the charging status.
3. Once fully charged, remove the battery from the charger.
4. To install the battery into the chainsaw, align the battery with the battery port on the chainsaw and slide it in until it locks securely.
5. To remove the battery, press the release latch and slide the battery out.

4.2 Chain Tensioning

Proper chain tension is crucial for safe and efficient operation. Check chain tension before each use and periodically during operation.

1. Ensure the chainsaw is turned off and the battery is removed.
2. Locate the side access chain tensioning screw on the side of the chainsaw.
3. Loosen the bar retaining nuts slightly.
4. Turn the tensioning screw clockwise to tighten the chain or counter-clockwise to loosen it. The chain should be snug against the guide bar, but still able to be pulled freely by hand. There should be no sag on the underside of the guide bar.
5. Once the desired tension is achieved, tighten the bar retaining nuts securely.

4.3 Adding Chain Oil

The chainsaw requires bar and chain oil for lubrication. Check the oil level before each use.

1. Ensure the chainsaw is turned off and the battery is removed.
2. Locate the oil reservoir cap, typically on the top or side of the chainsaw body.
3. Unscrew the cap and fill the reservoir with quality bar and chain oil. Do not use waste oil or other lubricants.
4. Replace the cap securely.

5. Operating Instructions

5.1 Starting the Chainsaw

Before starting, ensure all safety checks are complete and the work area is clear.

1. Hold the chainsaw firmly with both hands.
2. Engage the chain brake (if applicable, typically by pushing the front hand guard forward).
3. Press the safety lockout button with your thumb.
4. Squeeze the variable speed trigger to start the chainsaw. Release the safety lockout button once the trigger is engaged.
5. To stop the chainsaw, release the trigger.

5.2 Cutting Techniques

Always maintain a stable stance and proper balance. Plan your cuts to avoid pinching the guide bar or experiencing kickback.

• Limbing: When cutting branches, support the branch to prevent it from falling unexpectedly. Cut from the top down for smaller branches, or use an undercut/overcut method for larger ones.
• Bucking: When cutting a log into sections, ensure the log is stable. If cutting a log on the ground, avoid cutting into the soil, which dulls the chain quickly.
• Felling: Felling trees requires advanced training and should only be performed by experienced operators. Always assess the tree's lean, wind direction, and escape routes.

6. Maintenance

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

• Cleaning: After each use, remove the battery and clean the chainsaw thoroughly. Remove sawdust, chips, and debris from the guide bar, chain, and motor housing.
• Chain Sharpening: A dull chain is inefficient and dangerous. Sharpen the chain regularly or replace it when necessary. Refer to the chain manufacturer's guidelines for proper sharpening angles.
• Chain Oil: Always ensure the oil reservoir is filled with appropriate bar and chain oil.
• Guide Bar Maintenance: Periodically clean the guide bar groove and check for burrs. Flip the guide bar regularly to ensure even wear.
• Storage: Store the chainsaw in a dry, secure location, out of reach of children. Remove the battery before storage.
