Usage & Maintenance Tips

Prime a new coil by applying a few drops of e-liquid directly to the exposed wick holes before assembling
Fill via the base after unscrewing — avoid overfilling past the fill line
Give 30–60 seconds after filling before vaping to allow wick saturation
Replace coil when vapour or flavour noticeably declines
Clean tank base threads and 510 connection periodically for better conductivity
Store upright when not in use to protect seals and reduce leakage
