Tips

For the best battery life, store the batteries at room temperature and charge them fully before first use. When cutting metal, use a fine-tooth blade and apply light pressure to avoid overheating. Always engage the restart protection when changing blades or batteries. The LED light is especially useful in dark crawl spaces or behind walls—keep the lens clean for maximum visibility.
