Insufficient cooling may cause plastic components to become fused, which may lead to burns or to a fire if burning parts get in contact with sawdust.

The battery is unstable and does not stay upright during functioning; it is possible that it falls on its side. If that happens, burning projectiles could hit persons, causing burns, or come into contact with flammable material, causing a fire. The product does not comply with the requirements of the Pyrotechnics Directive and the relevant European standard EN 15947.
