5. Configuració
5.1. Càrrega de la bateria
- Connect the Bivolt charger to a standard 110V or 220V power outlet.
- Insert the 48V battery into the charger. Ensure a secure connection.
- Allow the battery to charge for approximately 6 to 8 hours for a full charge. The charger typically has an indicator light to show charging status.
- Un cop carregada completament, desconnecteu la bateria del carregador i el carregador de la presa de corrent.
5.2. Instal·lació de la cadena i la barra guia
Before installation, ensure the battery is removed from the chainsaw.
- Remove the chain cover by loosening the retaining nut.
- Carefully place the saw chain around the guide bar, ensuring the cutting edges are facing the correct direction (refer to markings on the chain).
- Fit the guide bar and chain onto the chainsaw's drive sprocket.
- Replace the chain cover and lightly tighten the retaining nut. Do not fully tighten yet.
- 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 a small amount of play (approx. 2-3mm) when pulled away from the guide bar.
- Once the tension is correct, fully tighten the retaining nut.
6. Instruccions de funcionament
6.1. Arrancada i aturada
- Ensure the battery is fully charged and securely installed in the chainsaw.
- Agafeu fermament la motoserra amb les dues mans.
- To start, press the safety lock button (if present) and then squeeze the trigger switch. The chain will begin to move.
- To stop, release the trigger switch. The chain will stop rotating.
6.2. Tècniques de tall
Always maintain a stable stance and clear footing.
- Branques petites: For small branches, use a single, smooth cutting motion.
- Larger Branches: For thicker branches, make a relief cut on the underside first to prevent pinching, then complete the cut from the top.
- Evitar el cobeig: Be aware of the kickback zone (the upper quadrant of the guide bar tip). Avoid cutting with this area.
- No forçar: Allow the chainsaw to do the work. Do not apply excessive pressure, as this can strain the motor and cause the chain to bind.

7. Manteniment
Regular maintenance ensures optimal performance and extends the life of your chainsaw. Always remove the battery before performing maintenance.
- Lubricació de la cadena: Regularly apply chain oil to the guide bar and chain to reduce friction and wear. Check the oil level (if applicable) or manually lubricate as needed.
- Afilat de cadena: A dull chain requires more effort and can cause kickback. Sharpen the chain regularly or replace it when necessary.
- Neteja: After each use, clean sawdust, debris, and resin from the guide bar, chain, and motor housing. Use a brush or compressed air.
- Manteniment de la barra guia: Periodically flip the guide bar to ensure even wear. Clean the guide bar groove.
