To remove the battery: Press the release button to remove the battery pack to the left.

NOTE: When the device is not in use, remove the battery and protect the battery contacts. Loose metal parts could cause a short circuit in the battery, leading to an explosion and fire risk.

4. Charging the Battery

NOTE: If the power cord needs to be replaced, this must be done by the manufacturer or its agent to avoid a safety risk.

Charging Procedure

Low Voltage Charging

If the battery has been stored with little or no charge for a long period, the charger will enter recovery mode, which will take longer to fully charge the battery. This will extend the battery's lifespan. Once fully charged, the next charge will return to standard charging. A completely discharged battery pack will require the time specified in the battery manual. Plug the charger into an AC outlet. Insert the battery into the charger. This is a diagnostic charger. The charger's LED lights will illuminate in a specific sequence to indicate the current battery status.

Incorrect Fault Indication

If the battery is inserted into the charger and the status LED remains GREEN, remove the battery from the charger for 1 minute, then reinsert it. If the status LED remains RED, the battery is charging correctly. If the status LED remains GREEN, remove the battery and unplug the charger for 1 minute. After 1 minute, plug the charger back in and reinsert the battery. If the status LED remains RED, the battery is charging correctly. If the status LED remains GREEN, the battery is defective and must be replaced.

Charging Check

If the battery pack does not charge correctly: Check the current at the outlet with another device. Make sure the outlet is switched on. Check that the charger contacts are not short-circuited by dirt or foreign objects. If the air temperature is above 40°C or below 7°C, move the charger and battery pack to a room temperature location and allow them to warm up slowly.

Operating Instructions

NOTE: Remove the battery pack and keep your hands away from the lock button when moving the machine.

IMPORTANT: Check the chain tension before each use.

1. Oiling the Chain

NOTE: Use only guide bar and chain oil specifically designed for chains and chain oilers.

1. Refill oil (oil not included. Overfilling the tank is not recommended).

   

2. Check the machine's oil level at the oil indicator.

   

3. Begin use.

2. Starting the Machine

1. Press button "A" to unlock the safety switch. Simultaneously press button "B" to start the machine.
2. Release button "A".

3. Using the Chainsaw

Holding and Controlling the Chainsaw

• Hold and control the chainsaw with one hand on the grip area (a) of the handle – wrap your thumb around the handle.
• Hold and control the chainsaw with your other hand on the grip surface (b).

Cutting

• Start the cut with the chain running at full speed.
• Engage the stop and use it as a lever.
• Continue cutting until the guide bar is completely through the branch.
• Take the weight of the chainsaw at the end of the cut.

NOTE: After use, please drain the oil from the chainsaw's oil tank to prevent oil leaks that could affect its use.

4. Adjusting Chain Tension

New chains stretch at the beginning of use. Please check and adjust the tension regularly, as a loose chain can easily come off, leading to rapid wear of the chain and guide bar. If the chain becomes loose during use, it should be adjusted as follows:

1. Slightly loosen the screws on the chain cover.

   

2. Adjust the chain tension with a screwdriver.

   NOTE: Turn the adjustment screw clockwise to tighten the chain, and counter-clockwise to loosen it.

   

3. Ensure a 2-3 mm gap when pulling individual links from the guide bar.

   

4. Tighten the screws on the chain cover firmly.

   

Maintenance

CAUTION: Do not allow brake fluids, gasoline, or petroleum-based materials to come into contact with plastic parts. Chemicals can damage plastic and render it unusable.

CAUTION: Do not use strong solvents or detergents on the plastic housing or components.

CAUTION: Remove the battery pack from the machine before beginning maintenance.

1. Maintenance and Cleaning

1. Clean the chain carefully after each use.
2. Clean the guide plate grooves and gears after use.
3. Wipe the chain with lubricating oil and spray it with metal protective spray.
4. Do not spray the equipment with water or immerse it in water. Otherwise, an electric shock could occur.
5. Regularly clean the machine housing with a soft cloth, preferably after each use.
6. Keep fans, motors, and handles clean.
7. Remove stubborn dirt using a soft cloth moistened with soapy water.
8. Do not use solvents such as gasoline, alcohol, ammonia, etc. These chemicals will damage synthetic components.

2. Sharpening the Cutting Teeth

Sharpen the cutting teeth if the chain struggles to penetrate wood.

NOTE: We recommend that a service center with an electric sharpener performs important sharpening work.

1. Check chain tension.

   

2. Sharpen the cutting teeth with a round file with a diameter of 2 mm to 2.5 mm.

   

3. Sharpen the top plate, side plate, and depth gauge with a flat file.

   

4. File all cutting teeth to the same angle and length.

   HINTS: During the process:

   • Keep the file flat against the surface to be sharpened.
   • Use the middle of the file bar.
   • Apply light but firm pressure when sharpening.
   • Lift the file after each backstroke.
   • Sharpen the cutting teeth on one side, then switch to the other side.

Replace the chain if:

• The length of the cutting edges is less than 5 mm.
• There is too much play between the drive sprockets and the rivets.
• The cutting speed is slow.
• Sharpening the chain does not increase the cutting speed. The chain is worn out.

3. Guide Bar Maintenance

NOTE: Be sure to periodically rotate the guide bar to ensure symmetrical wear.

1. Lubricate the bearings on the nose sprocket (if present) with a syringe (not included).

   

2. Clean the guide bar groove with a scraping tool (not included).
3. Clean the lubrication holes.
4. Remove burrs from the edges and level the cutters with a flat file.

   

Replace the guide bar if:

• The groove does not match the height of the drive links (they should never touch the bottom).
• The inside of the guide bar is worn and causes the chain to deviate to one side.

4. Transport and Storage

Before moving the machine, always remove:

1. The battery pack from the machine.
2. Keep hands away from the lock button. Place the cover on the guide bar and chain. Before storing the machine, always remove:
3. The battery pack from the machine.
4. Remove any residual oil from the machine.
5. Clean all unwanted materials from the machine.
6. Ensure the storage area is inaccessible to children.
7. Store away from corrosive agents such as garden chemicals and de-icing salt.

User Tips

• Automatic Lubrication is Key: Users appreciate the automatic oil pump. Ensure the oil tank is filled before use, but avoid overfilling. Remember to empty it after each use to prevent leaks.
• Chain Tension is Crucial: Regularly check and adjust chain tension. A loose chain can easily come off and cause rapid wear. Keep a chain adjustment tool handy (unless your model has tool-free adjustment).
• Battery Management: Fully charge batteries before first use. If a battery has been stored for a long time with low charge, it may take longer to fully charge as the charger enters recovery mode. Store batteries in a cool, dry place (0-30°C / 32-86°F) with 40-80% humidity.
• Portability and Balance: The chainsaw is noted for being lightweight and well-balanced, making it suitable for reaching dense canopies or for users who prefer one-handed operation.
• Compatibility: This chainsaw is compatible with Makita 18V batteries, offering flexibility if you already own tools from that system.
• Safety First: Always remove the battery pack when moving the machine or performing maintenance. Ensure the safety switch is engaged when not actively cutting.
