Typically, 30-60 minutes to cool sufficiently. In extreme cases, it may take longer. Always let it cool to room temperature before using.
Can I use a different battery to bypass error code 1?
Yes, if you have another compatible battery, you can try it. If the tool works with a different battery, the original battery likely has a problem. If the error appears with all batteries, the tool may need service.
