3. Montagem
Follow these steps to assemble your UBeesize Mini Chainsaw:
3.1 Instalação da barra guia e da corrente
- Ensure the battery is removed from the chainsaw before beginning assembly.
- Remova a tampa da corrente desapertando o botão.
- Carefully place the chain around the sprocket and then guide it into the groove of the guide bar. Ensure the cutting edges of the chain teeth are facing the correct direction (away from the motor).
- Position the guide bar and chain onto the chainsaw body, ensuring the chain fits around the drive sprocket.
- Replace the chain cover and lightly tighten the knob. Do not fully tighten yet.
3.2 Ajuste da tensão da corrente
- With the chain cover lightly tightened, use the tool-free tension knob (red knob on the side) to adjust the chain tension.
- The chain should be snug against the guide bar but still able to be pulled freely by hand. There should be no excessive slack. A properly tensioned chain will have a small gap (approx. 2-3mm) between the chain and the bottom of the guide bar when lifted from the center.
- Once the tension is correct, fully tighten the chain cover knob securely.

- Parando: Release the trigger switch to stop the chainsaw. The chain should stop immediately.
5.2 Técnicas de Corte
- Branch Trimming: For small branches, make a cut from the top down. For larger branches, make an undercut first to prevent pinching, then complete the cut from the top.
- Corte de madeira: Ensure the wood is stable and supported. Apply steady, even pressure. Let the chainsaw do the work; do not force it.
- Evite beliscar: Be aware of the natural movement of the wood as you cut. If the chain gets pinched, release the trigger, remove the chainsaw, and reposition.
