1. Ensure the battery is removed before assembly.
2. Remove the side cover by unscrewing the retaining nut.
3. Place the chain around the sprocket and guide bar, ensuring the cutting edges face the correct direction (refer to markings on the chain).
4. Fit the guide bar and chain onto the chainsaw body, ensuring the chain engages with the drive sprocket.
5. Replace the side cover and hand-tighten the retaining nut.
6. Adjust chain tension: The chain should be snug against the guide bar but still able to be pulled freely by hand. There should be no more than 2-3mm of slack when pulled from the center of the guide bar. Use the provided screwdriver or tensioning mechanism to adjust.
7. Fully tighten the retaining nut.

4.3 Lubrication

The Saker Mini Chainsaw requires manual lubrication. Before each use, apply a small amount of chain oil (not included, but a bottle is provided for storage) to the guide bar groove and chain. This ensures smooth operation and extends the life of the chain and bar.

5. Operating Instructions

Always follow safety guidelines before and during operation.

5.1 Starting and Stopping

1. Ensure the battery is fully charged and installed, and the chain is properly tensioned and lubricated.
2. Hold the chainsaw firmly with one hand on the main handle and the other on the auxiliary handle (if applicable).
3. To start, press the lock-off button (if present) and then squeeze the trigger switch. The chain will begin to move.
4. To stop, release the trigger switch. The chain should stop immediately.

5.2 Cutting Techniques

• Always make sure the chain is at full speed before contacting the material to be cut.
• Apply light pressure. Let the chainsaw do the work. Forcing the saw can lead to overheating and damage.
• When cutting branches, support the branch to prevent pinching the guide bar. Cut from the top down for smaller branches, or make an undercut first for larger ones to prevent tearing.
• Avoid cutting into the ground or other hard objects, as this will dull the chain quickly.
• Be mindful of kickback, especially when the tip of the guide bar contacts an object.

6. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your chainsaw.

6.1 Cleaning

• Always remove the battery pack before cleaning.
• Use a brush or compressed air to remove sawdust, chips, and debris from the motor housing, guide bar, and chain.
• Wipe down the exterior with a damp cloth. Do not use harsh chemicals or solvents.

6.2 Chain Sharpening

• A dull chain will cut slowly and inefficiently. Sharpen the chain regularly or replace it when necessary.
• Refer to the chain manufacturer's specifications for the correct file size and sharpening angle.
• Alternatively, have the chain professionally sharpened.

6.3 Storage

• Store the chainsaw in a dry, secure location, out of reach of children.
• Remove the battery pack before storing for extended periods.
• Use the guide bar cover to protect the chain during storage and transport.
