Automatic Oiling System
This mini chainsaw is equipped with an automatic chain lubrication system. Proper lubrication is crucial for smooth cutting and to reduce wear and tear on the chain and guide plate.
- Open the black cover of the oil tank.
- Pour 10-20ml of lubricating oil (general motor oil is suitable) into the fuel tank. Do not exceed 30ml.
- Close the black lid tightly to prevent leakage.
- Before starting the chainsaw, press the transparent button 3-4 times to circulate oil to the chain.
It is recommended to lubricate the chain every 20 times of cutting wood to ensure a smooth cut and prolong the life of the chain.

Maintenance
Post-use Storage Instructions
Proper storage ensures the longevity and optimal performance of your chainsaw:
- Ensure the Chainsaw is Cleaned and Dried thoroughly after each use.
- Store the Chainsaw Upright to prevent lubricant leakage.
- Drain Excess Lubricant from the tank if storing for an extended period.
- Make sure the oil cap is tightly closed to prevent leakage during storage.
Troubleshooting
Warnings About Common Mistakes
To avoid common issues and ensure safe operation:
- Avoid storing the chainsaw on its side or upside down. This can lead to lubricant leakage, as gravity can cause the oil to flow out of the reservoir.
- Do not leave the oil cap loosely closed. This can lead to leakage during storage, especially if the chainsaw is moved or bumped.
- Don’t neglect to check the chainsaw for oil leaks, cracks, or damage after each use. Storing a damaged tool can lead to leaks during storage.
