2. Informació de seguretat
Seguiu sempre les precaucions de seguretat bàsiques quan utilitzeu eines elèctriques per reduir el risc d'incendi, descàrrega elèctrica i lesions personals.
- Seguretat de l'àrea de treball: Mantingueu la vostra zona de treball neta i ben il·luminada. Les zones desordenades o fosques conviden als accidents. No feu servir eines elèctriques en atmosferes explosives, com ara en presència de líquids, gasos o pols inflamables.
- Seguretat elèctrica: Eviteu el contacte corporal amb superfícies connectades a terra (per exemple, canonades, radiadors, fogons, neveres). No exposeu les eines elèctriques a la pluja ni a condicions humides.
- Seguretat personal: Utilitzeu sempre protecció ocular. Utilitzeu protecció auditiva quan opereu durant períodes prolongats. Vestiu-vos correctament; eviteu roba ampla o joies. Mantingueu els cabells, la roba i els guants allunyats de les parts mòbils.
- Ús i cura de l'eina: No forceu l'eina elèctrica. Feu servir l'eina elèctrica correcta per a la vostra aplicació. Desconnecteu l'endoll de la font d'alimentació abans de fer qualsevol ajust, canviar accessoris o guardar eines elèctriques. Guardeu les eines elèctriques inactives fora de l'abast dels nens i no permeteu que persones que no estiguin familiaritzades amb l'eina elèctrica o amb aquestes instruccions la facin funcionar.
- Seguretat de la bateria: Do not disassemble, open, or shred battery packs. Do not expose battery packs to heat or fire. Avoid direct sunlight. Do not short-circuit a battery pack.

10. Consells d'usuari
- Utilize 'A' Mode: For general screwing tasks, especially if you're new to power tools, the intelligent 'A' gear mode can prevent stripping screws or damaging surfaces by automatically adjusting torque.
- Match Bit to Task: Always select the correct drill bit or screwdriver bit for the material and fastener size. Using the wrong bit can lead to inefficiency or damage.
- Pre-drill Pilot Holes: For harder materials or when working close to edges, pre-drilling a small pilot hole can prevent wood splitting and make screwing easier.
- Keep Bits Clean: Regularly clean your drill bits and screwdriver bits to ensure optimal performance and longevity.
- Peça de treball segura: Sempre clamp or secure your workpiece firmly before drilling or screwing to prevent movement and ensure accuracy.
