Key Parts:

• Guide Bar: Supports and guides the cutting chain.
• Cutting Chain: The cutting element of the chainsaw.
• Front Handle: For stable two-hand operation.
• Rear Handle: Contains the trigger and safety switch.
• Handguard: Protects the operator's hand from the chain.
• Chain Brake: Safety feature to stop the chain quickly.
• Oil Reservoir Cap: For filling chain lubricant.
• Battery Compartment: Houses the 18V battery.
• Chain Tensioning Screw: Adjusts chain tension.

Setup

Before initial use, assemble and prepare your chainsaw according to these steps.

1. Battery Charging and Installation:

1. Insert the 18V battery into the provided 1.5A charger.
2. Plug the charger into a suitable 1.5A bivolt power outlet.
3. Allow the battery to charge fully. Refer to the charger's indicator lights for charging status.
4. Once charged, remove the battery from the charger.
5. Align the battery with the battery compartment on the chainsaw and slide it in until it clicks securely into place. Ensure it is fully seated.

2. Guide Bar and Chain Assembly:

Note: Always wear protective gloves when handling the chain.

1. Ensure the battery is removed from the chainsaw.
2. Remove the side cover by loosening the retaining nuts/knob.
3. Place the chain around the sprocket and then guide it into the groove of the guide bar. Ensure the cutting edges of the chain are facing the correct direction (usually indicated by an arrow on the chain or bar).
4. Fit the guide bar onto the chainsaw studs, ensuring the chain drive links engage with the sprocket.
5. Replace the side cover, but do not fully tighten the retaining nuts/knob yet.

3. Chain Tensioning:

Proper chain tension is crucial for safe and efficient operation.

1. With the side cover loosely attached, use the chain tensioning screw (typically located on the side cover or near the bar) to adjust the chain tension.
2. The chain should be snug against the bottom of the guide bar, but still able to be pulled freely by hand. There should be no excessive slack. A good test is to lift the chain from the guide bar; the drive links should not come out of the bar groove.
3. Once the tension is correct, fully tighten the side cover retaining nuts/knob.
4. Re-check chain tension after tightening the cover.

4. Filling the Chain Oil Reservoir:

The chainsaw requires chain lubricant to reduce friction and wear on the chain and bar.

1. Ensure the battery is removed.
2. Locate and unscrew the oil reservoir cap.
3. Fill the reservoir with high-quality chain and bar oil. Do not use motor oil or waste oil.
4. Replace the cap securely.
5. Periodically check the oil level during operation and refill as needed.

Operating Instructions

Follow these steps for safe and effective operation of your chainsaw.

1. Starting the Chainsaw:

1. Ensure all safety checks are complete (battery installed, chain tension correct, oil reservoir full, chain brake disengaged).
2. Hold the chainsaw firmly with both hands, one on the front handle and one on the rear handle.
3. Engage the safety lock-off button (if present) and then squeeze the trigger to start the chain.
4. Allow the chain to reach full speed before beginning a cut.

2. Cutting Techniques:

• Stance: Maintain a balanced stance with feet shoulder-width apart.
• Cutting Angle: Always cut with the bottom edge of the guide bar for better control and to reduce kickback risk.
• Avoid Kickback: Never cut with the tip of the guide bar. Be aware of branches under tension.
• Small Branches: Cut small branches with a single pass.
• Larger Logs: For larger logs, make an undercut first (if necessary) to prevent pinching, then complete the cut from the top.
• Clear Debris: Stop the chainsaw and remove the battery before clearing any jammed debris.

3. Stopping the Chainsaw:

1. Release the trigger. The chain should stop quickly.
2. Engage the chain brake for added safety when moving between cuts or when the chainsaw is idle.
3. Always remove the battery when the chainsaw is not in use, being transported, or stored.

Maintenance

Regular maintenance ensures the longevity and safe operation of your chainsaw. Always remove the battery before performing any maintenance.

1. Cleaning:

• After each use, clean sawdust, chips, and debris from the chainsaw body, guide bar, and chain.
• Use a brush or compressed air. Do not use water to clean electrical components.
• Clean the air vents to prevent overheating.

2. Chain Sharpening:

• A sharp chain is essential for efficient cutting and safety. Sharpen the chain regularly or replace it when dull.
• Refer to the chain manufacturer's specifications for the correct file size and sharpening angles.
• If unsure, have the chain sharpened by a qualified service technician.

3. Guide Bar Maintenance:

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

4. Chain Oil:

• Always ensure the chain oil reservoir is adequately filled before and during operation.
• Use only recommended chain and bar oil.
