What to do if my Hilti SF 2-A12 Drill battery becomes very warm?

If the power tool or the battery becomes very warm, it may indicate an electrical fault. Immediately switch off the power tool, remove the battery, keep it under observation, and allow it to cool down. After that contact Hilti Service.
